1. Which wavelength of light has an effect on plants

In the natural spectrum, the effects of different spectral bands on plant physiology include:

280～315nm has the least influence on morphology and physiological process;315～400nnm chlorophyll absorbs little, which affects the photoperiod effect and hinders stem elongation;400～520nm (blue light) has the largest absorption ratio of chlorophyll and carotenoids, and has the greatest impact on photosynthesis;The absorption rate of 520～610nm pigment is not high;610～720nm (red light) chlorophyll absorption rate is low, which has a significant impact on photosynthesis and photoperiod effect;

The absorption rate of 720～1000nm is low, which stimulates cell elongation and affects flowering and seed germination;>1000nm is converted into heat.

In the visible light waveband, 400-520nm blue light and 610-720nm red light have the greatest impact on plants, while in the blue and red light wavebands, 450nm blue light and 660nm red light have significant effects on plants.

The light efficiency is increased by more than 50%, which is safe, environmentally friendly and energy-saving.

3. How to choose LED grow light source parameters

Selection of LED grow light source intensity

When designing plant light intensity, you need to refer to two key points of plant photosynthesis, one is the light compensation point and the other is the light saturation point.

The light compensation point means that as the light intensity decreases, the photosynthetic rate decreases. When the light intensity decreases to a certain value, the photosynthetic rate of the leaves is equal to the respiration rate, and the net photosynthetic rate is zero. The light intensity at this time is called light compensation. View. At this time, if the photosynthesis of the plant is to continue, additional light compensation is required.

The light saturation point is above the light compensation point. As the light intensity increases, the photosynthetic rate also increases accordingly. When reaching a certain light intensity, the photosynthetic rate no longer increases with the increase of light intensity. This phenomenon is called light intensity. Saturation phenomenon. The light intensity at which the maximum photosynthetic rate is reached is called the light saturation point. If the external light is stronger than the light saturation point of the plant, it will form a waste of light.

How to choose the right LED plant light for seedling and plant growth

How to choose suitable LED plant lights for plants and seedlings? This is a problem that both junior growers and experienced growers must pay attention to. Appropriate LED plant lights can give seedlings and plants a better growth environment and supplement light. We can start from the following points.

1. Planting environment When choosing the supplementary light, you should choose the appropriate supplementary light according to the planting environment. If it is planted indoors, when choosing the 1000wled plant supplementary light, you must choose the full-spectrum LED plant supplementary light, red The blue light fill light is harmful to the human body and will make people dizzy and nauseous for a long time. Outdoor or in a greenhouse with high humidity, you should choose a waterproof LED plant supplement light lamp, which can extend the life of the LED plant supplement light lamp and ensure normal use.

2. Crop types Different crops do not require light. For wild vegetable crops, we can choose to use full-spectrum fill light, which is reasonably priced and sufficient to achieve the fill light effect. For fruits and crops and flowers, you can choose red and blue light supplement light, which has a good supplement light effect in promoting the growth of stems and leaves, flowering and fruit, preventing overgrowth and coloring.

3. Crop growth requirements When selecting the power of the supplement light, the supplement light of the appropriate power should be selected according to the requirements of the crop for the light intensity and light time. Crops with long light need long-term supplement light. Long-term use will shorten the service life of the supplement light. Therefore, when choosing, pay attention to the warranty period of the supplement light to ensure the service life.

4. Supplementary lights merchants When choosing supplementary lights, in addition to paying attention to their own needs for supplementary lights, they should also pay attention to the strength of the 1000wLED plant supplementary lights. Competent fill-light vendors have guarantees on the quality and price of fill-lights. For example, LED plant supplement light manufacturers will absolutely strictly control price and quality to ensure the effect of supplement light.

LED plant light red and blue lamp beads ratio layout

All the plans of LED plant lights must be customized around plants. What kind of shape the plants need to grow into is cultivated according to the needs of people. Therefore, when looking at the ratio of red and blue beads of LED plant lights, the plant must be considered first. Growth needs and human needs.

But from the perspective of light, whether it is the demand for plant growth or human demand for plants, the control methods include control of light quality, control of light intensity, and control of light time. Only in this way can the light intensity reach the point required by the plant, and the light time can reach a certain length of time, giving the plant a better growth state.

When LED plant lights are used to supplement light to plants, the source of most of the light for plant photosynthesis is LED plant lights. The different light qualities of LED plant lights have different physiological meanings to plants. LED plant lamp lamp beads chips are mainly red lamp beads, blue lamp beads, and full-spectrum lamp beads. The main function of red light on plants is to adjust the photoperiod of plants, and the main function of blue light is to affect the movement of leaves and plastids, to a certain extent Inhibit the flowering and fruiting of plants; the main band of full-spectrum lamp beads is also the red and blue spectrum.

Spectrum: When using LED plant growth lights to grow plants, red light and blue light are very important. It is necessary to look for blue in the range of 440-470nm, and red in the range of 610 to 720nm. These two stages of the spectrum affect the photosynthesis of plants The contribution is the greatest, and other lights also have a weak effect. A better choice is the full-spectrum LED plant light, which can meet the spectrum required by each stage of the plant and can also be adjusted, which can give plants better growth.

Output: This is one of the most important characteristics of LED plant growth lights, and it will affect plant yields. When reading the product description. Will introduce the power of the LED plant light, it can be 400W, 600W, 800W or even 1000W. Generally, it is not always possible to obtain 100% power, and usually the final wattage is low.

Lens: Good-quality LED plant growth lights have an optical lens that can magnify the light and provide about 25% of the nutrient penetration for plants. This makes LED grow lights more expensive, but they are definitely worth the money.

Heat dissipation: LED plant growth lights usually work around 15 hours a day, so you need to ensure that they dissipate heat well, and try to use integrated die-cast aluminum alloy instead of fans or other plastic materials.

Warranty: Look for LED plant growth lights with at least five years of warranty, because this is the guarantee given by powerful manufacturers. The ideal life of LED plant lights is 50,000 hours, which is about 10 years. However, considering various factors, the actual working life will be about 5 years, so a 5-year warranty is the best choice.

Pay attention to the misunderstanding:

(1) The life of LED plant lights is not equal to working time

The lifespan of LED plant lights from most manufacturers can reach more than 50,000 hours. This life is the theoretical life that the lamp can use. The factors of light decay and technology replacement are not explained.

The light decay of LED plant lights includes many aspects. On the one hand, it is the lamp chip itself, the brightness of any lighting lamp will decrease after a long time working. On the other hand, accessories, including wires, panels, lenses, covers, etc., will age after a long period of time. Even if a new LED chip is replaced, it is impossible to achieve the best plant lighting effect as before.

(2) The higher the power, the greater the brightness, the better the effect

Power refers to the power consumption of the LED plant light in a certain period of time, and has no direct relationship with the light supplement effect of the LED plant light. The key factors that we should pay attention to are workmanship, quality and effectiveness. Brightness is the definition of light perception by the human eye. The perception of light by plants is calculated based on the illuminance lux. It is not that the brighter the human eye feels, the better the effect of LED plant lights. We'd better choose different LED chip ratios according to different stages of plant growth to achieve the best growth of plants at different stages.

(3) LED plant light is a cold light source, it will not burn plants

LED plant lights are cold light sources, compared to other plant growth lights. All products related to electricity generate heat. At present, there is no photoelectric conversion source that can achieve 100% photoelectric conversion, and more or less of the electric energy will be converted into heat energy, and the same is true for LED plant lights.

Low-power LED plant growth lights can illuminate plants at a close distance, especially during the germination stage. However, if the 600wLED plant growth light is attached to the plant, the heat radiated to the plant for a long time will also burn the plant. When the power is high, you must use an air conditioner or fan to dissipate heat.

Hope this can help you choose a good LED plant growth lamp and give plants better light.

What will the LED plant light be used for hydroponic cultivation of hemp?

When growing cannabis plants indoors, a proper lighting system is another important factor to consider. With the invention of LED lights, these are considered to be the best hydroponic light sources, allowing hemp to produce more buds and flowers at a high growth rate. Compared with standard halogen lamps, high pressure sodium lamps (HPS), fluorescent lamps or metal halide (MH) plant lights, hydroponic LED plant lights are more energy-efficient. Unlike traditional plant growth lights, LED plant growth lights can be specially adjusted according to the specific spectrum required for a specific growth stage. Cannabis is very sensitive to light, and light intensity, color and frequency need to be adjusted according to each stage of its growth.

As a herb that grows throughout the year, hemp, in addition to a particularly important attribute that people know, it also has more uses. For example, it is a raw material for fiber products, clothing, ropes, sails, grease, paper, and medical supplies. Has a lot of medicinal value. Therefore, in addition to the development of large-scale outdoor cannabis cultivation, there are also indoor hydroponic cultivation and cultivation.

Hydroponic cultivation is to create a relatively closed environment that can store nutrient solution through specific facilities, and keep the water, fertilizer, gas, heat and other conditions required for root growth relatively stable, and all or part of the root system is "immersed" in the nutrient solution. Cultivation methods.

When planting indoors, LED plant lights can be used to supplement light during hydroponic cultivation. LED plant lights are made according to the absorption and utilization of sunlight by plant growth, and the spectrum and light intensity meet the requirements. It can be used to supplement light for vegetables, seedlings, fruits, and flowers. It can not only promote the progress of photosynthesis, but also achieve the effects of increasing production and increasing, launching in advance, and enhancing quality.

Photosynthetically active radiation (PAR) is a wavelength band between 400 nanometers and 760 nanometers. The PAR band starts from the purple spectrum (380nm to 450nm). Light in this range is believed to improve the color, potency and taste of flowers, and does not play an active role in the photosynthesis process. After that, the blue spectrum lies between 450 nm and 495 nm, which is very important for photosynthesis and the rapid growth of cannabis. This color of light is most commonly used in the germination and vegetative stages of growth because it promotes the rapid growth and development of plants. After the blue spectrum, the wavelengths from 495 nm to 570 nm represent the green spectrum of light. Cannabis plants absorb very little green light energy, but there are reports that small amounts can affect growth. The wavelength range of yellow light energy is from 570 nm to 590 nm. Although less important during photosynthesis, yellow/red light promotes germination and is essential during the flowering stage of plant growth. The final color of the visible spectrum is red. Its wavelength range is 620 nm to 760 nm.

This light is needed during the flowering period of hemp. Adding red light will induce buds and flowering. When the plant reaches the flowering stage, many cannabis growers switch to a more pronounced red light source. The mixed blue red light gets the best response from the cannabis plant. Its wavelength range is 620 nm to 760 nm. This light is needed during the flowering period of hemp. Adding red light will induce buds and flowering. When the plant reaches the flowering stage, many cannabis growers switch to a more pronounced red light source. The mixed blue red light gets the best response from the cannabis plant. Its wavelength range is 620 nm to 760 nm. This light is needed during the flowering period of hemp. Adding red light will induce buds and flowering. When the plant reaches the flowering stage, many cannabis growers switch to a more pronounced red light source. The mixed blue red light gets the best response from the cannabis plant.

The higher PAR of the hydroponic cannabis LED plant light can promote faster growth of cannabis and can lead to larger buds. Some people suggest that light intensity is even more important than spectrum. Use photon flux to measure the intensity of light. Photosynthetic photon flux (PPF) indicates how many photosynthetically active photons are emitted from a light source per second. By knowing the PPF value of the light source, the total light output that contributes to photosynthesis can be found. The unit used to express PPF is micromole per second (μmol/s). The effectiveness of PAR is a measure of the amount of photosynthetic light (μmol/J) produced per joule of energy. For indoor cannabis cultivation, it is recommended to use energy-saving lamps with high PAR efficiency.

Cannabis requires dark and light periods at specific intervals to achieve optimal growth. The hydroponic lighting system should be equipped with a timer or IoT-based equipment to help growers control the lighting. The optimal photoperiod depends on the specific plant species. Indoor cannabis growers tend to buy full-spectrum LED plant lights for cannabis to maximize its growth and produce more buds and flowers.

Adjust the light intensity, uniformity of light and control temperature through LED plant lights to provide the best supplement light for cannabis hydroponic cultivation, so that the final output of cannabis will increase, but also pay attention to the harvest time. As more and more countries legalize cannabis, Let the market of LED plant lights be broader, and the prospects are promising.

Why do LED plant lights need heat dissipation

All electronic products need heat dissipation. LED plant lights are no exception. If they work for a long time, they will generate a lot of heat. If the heat dissipation problem is not solved, it will first affect the LED plant light lamp bead decay and other issues, secondly it may cause a short circuit, and finally it will always affect the LED. The service life of plant lights.

In fact, there are two kinds of plant lights: high-power plant lights and low-power plant lights. LED plant lights, like all electrical products, will generate heat during use, leading to an increase in ambient temperature and temperature. At present, low-power LED plant lights can be used without special heat dissipation measures, only a basic heat dissipation structure is required, because the LED plant lights have high electro-optical conversion efficiency and relatively no heat generation.

LED high-power plant lights are not the case. If the heat dissipation problem is ignored, it will not only affect the service life of the LED plant lamp, but also burn the lamp tube, and also affect the normal growth of the irradiated plant.

In the manufacturing process of LED plant growth lamps, heat dissipation is an important link. At present, the main heat dissipation measures adopted by LED plant growth lamps are as follows:

1) Fan cooling:

The principle of using a fan to transfer the heat generated by the LED plant light to the air is very simple. Similar to the heat dissipation principle of the computer and TV in daily use, the fan is used to convection the air to ensure that the temperature of the air around the heating element is not too high. It is simply generated by the fan, LED plant growth lamp and transmitted to the hot air in the air, and then Supplement normal temperature air to achieve the effect of heat dissipation.

2) Natural heat dissipation:

Natural heat dissipation means that no external measures are required, and it works directly inside the LED plant light. The main principle is to make the LED plant growth lamp have a larger contact area with the air, and use components with better thermal conductivity, so as to better produce lamps. The heat is transferred to the air, and then through natural convection, that is, the hot air rises and the cold air fills the position, so as to achieve the purpose of cooling the LED plant light.

At present, heat dissipation fins, lamp housings, system circuit boards, etc. are mainly used, which is also a relatively low cost and good heat dissipation method, which is widely used in various electrical equipment.

3) Electromagnetic heat dissipation:

Electromagnetic heat dissipation is called electromagnetic jet heat dissipation. Instead of using a fan to convection the air, it uses electromagnetic vibration to drive the cavity in the film to vibrate, so that the air continues to circulate to achieve the effect of heat dissipation. The technical difficulty is complicated. Some LED products are already on the market.

The benefits of LED plant light heat dissipation are:

1. Relatively prolong the service life of LED plant lights, the service life of LED plant lights is about 50,000 hours. If the heat dissipation is not good, the internal structure will age faster, and the service life of the lamp will definitely shrink sharply.

2. Light effect, any artificial light source has light decay. A very important factor that affects the speed of light decay is temperature. High temperature will accelerate the aging of materials. The same use LED plant lights, the same use for 50,000 hours, one at temperature In the high temperature environment for safe light, the irradiated crop is undoubtedly the latter, and its total yield and quality are higher than the former.

3. The effective heat dissipation configuration of the LED plant light also helps to control the ambient temperature. If the plant lamp is not heated, the local temperature around the lamp will be slightly higher for a long time, and the growth state of the plant will definitely be different from other places. This is not conducive to the overall temperature control of the greenhouse or plant factory.

LED plant light heat dissipation test

The heat dissipation performance of the LED plant light is directly related to its service life and the luminous efficiency of the lamp beads. If you want to see its heat dissipation performance, try an experiment to increase the temperature to an equilibrium state in a certain space for a period of time, and its internal structure will not be destroyed, and at a certain level Within time, the temperature of each part of the LED plant light will not increase with the prolonged high-intensity working time.

In cold regions, when planting medicinal plants and tomatoes, it is necessary to increase the temperature of the planting environment. In fact, the temperature rise of LED plant lights plays a big role. In fact, it can reduce additional temperature control costs and reduce energy waste. According to the actual scene of the application, select the corresponding LED plant light.

In addition to heat dissipation, there are several aspects that need to be paid attention to

Optical performance

In addition to the consideration of the ratio of red and blue light, it is also necessary to consider parameters such as luminous flux, luminous intensity, spectrum, luminous efficiency, and color temperature, because different plants have different requirements for red and blue light, luminous intensity, spectrum and color temperature.

Electrical performance

What needs to be paid attention to is the conversion of drive current and DC, as well as the need to pay attention to voltage drop, leakage, and static electricity, otherwise it will cause damage to the LED plant lamp beads and light decay, as well as people's safety issues.

Human radiation safety

The blue light of LED plant lights is the same as other electronic products, which is harmful to human eyes. This aspect should be paid attention to. Therefore, it is necessary to wear anti-blue goggles to protect the eyes.

The harm of blue light:

1. Blue light will aggravate the disease in the macular area of the retina;

2. Blue light can cause damage to the fundus after cataract surgery;

3. Blue light can cause blurred vision and cause visual fatigue;

4. Blue light can cause glare;

5. Blue light can inhibit the secretion of melatonin and disturb sleep.

Therefore, when purchasing LED high-power plant lights, the reliability of heat dissipation is an important technical indicator, and the yield and quality of later planted crops will also be directly reflected. Therefore, in addition to considering the price, the heat dissipation of LED plant lights is also worthy of attention.

How to plant seeds, place seedlings and choose LED plant lights for indoor plant

Indoor planting is not the same as outdoor planting. In addition to the need to supplement light, other requirements also need to be paid attention to. Sowing requires soil, and then distinguish which plants to plant. It should be noted that generally indoor planting is the cold season, so pay attention to the temperature, otherwise it will affect the growth of seedlings.

First, prepare fertile, well-drained soil and proper regional planning. Then place the seedlings so that they do not interfere with the seedlings, and then play the role of compaction, so that the supplementary light and temperature control can allow the seedlings to grow healthily.

Problems to pay attention to when planting

1. Indoor plants must be planted according to the specifications of specific varieties or hybrid varieties.

2. Compactness poses a serious threat to crops and is the cause of pests and diseases.

3. Make sure to leave a piece of land in the darkest place and place a bucket or water tank for fertilizer or pruned grass. During the fermentation process, carbon dioxide is released, which has a beneficial effect on plant growth and fruit setting.

After the above-mentioned problems about sowing are solved, the most critical plant light will be supplemented. Then how to choose LED plant lights?

Three points to know before choosing LED plant lights:

First of all, we must understand what plant to supplement light? Because different plants have different requirements for light intensity and spectrum, this affects the power selection and spectrum customization of LED plant lights; professional LED plant lights will customize the spectrum according to the needs of different crops at different growth stages, and the spectrum can significantly affect the light supplement Effect.

Understand the area and layout of the supplementary light area, which involves the selection of the size of the LED plant light, the layout and installation, to ensure the uniformity of light and increase the utilization rate, and use the entire space as reasonably as possible without causing regional waste.

Estimate the cost, the cost estimate of the LED plant light is determined according to your planting plants. If you are growing high-value plants, of course the cost of investment will be higher. On the contrary, lower it. In fact, the main thing is to meet the needs of your plants, and the right is the best. You can also find a professional person to help you with quotations and related questions, which will help you choose LED plant lights better.

Choosing LED plant lights can start from these 8 points:

1. PAR

PAR stands for "photosynthetically active radiation". It is a metric used in plants, while lumens are used in humans. So plants don't care how bright your lamps look. PAR in lighting is a wavelength in the visible light range of 400 to 700 nanometers (nm), and plants use this range for photosynthesis or growth.

2.PPF&PPFD

There are two stages related to photosynthetically active radiation (PAR). They are photosynthetic photon flux (PPF) and photosynthetic photon flux density (PPFD).

PPF simply describes the number of photons produced by the LED growth lamp in the PAR wavelength range in one second.

PPF is measured in units called micromoles (umol). You can use PPF to determine if your plant growth light is "strong enough."

PPFD is the number of photons that hit the canopy of a plant in a given second. This is measured in micromoles (umol). The larger the value, the better. The difference between PPF and PPFD is that PPF is the light intensity measured at the light source, while PPFD is the light intensity measured on the surface of the plant.

3. Light effect

Photon efficiency is a measure of how well a light source produces visible light. The unit of efficiency is Joules per second (J/s). If you know the PPF of the light and the input wattage, you can easily calculate the photon efficiency. The higher this number is, the higher the efficiency of the led plant growth lamp to convert electrical energy into photons.

4. LED chip

LED chip is the most necessary and basic aspect of LED plant growth lighting. Therefore, the manufacturing of chips must keep durability and efficiency in mind. A suitable LED chip can hardly appear color inconsistency while maintaining voltage and intensity. Elaborate chips can produce effective and uniform LED plant growth lights, which can support a variety of crops.

5. Spectrum

The spectrum refers to the electromagnetic wavelength of the light generated by the light source to promote plant growth. In order to carry out photosynthesis, plants use light in the PAR (Photosynthesis Effective Radiation) region. The wavelength of this region (400nm-700nm) is measured in nanometers (nm). Red light and blue light are the most critical for plants. Blue represents plant growth stage, while red represents flowering. In addition to red and blue, other wavelengths are also conducive to certain stages of plant growth. Ultraviolet rays help protect plants from insects and diseases, while more infrared rays than normal will make your plants think they are covered by something, so they need to grow taller to get more light. Compared with other wavelengths, green light can penetrate plant leaves farther and deep into the canopy. The ideal spectrum can help accelerate vegetation, increase flowering, accelerate growth, and so on. Whether the light source is an auxiliary light source (such as an indoor) or the only light source also affects which spectrum should be used.

Equipping your indoor plants with full-spectrum LED grow lights means that it can provide all the wavelengths present in natural light. All you need to do is to switch the amount of light the plant needs in different growth stages.

6. Heat dissipation

Although LED plant lights emit less heat than other traditional plant lights, putting many LED plant lights together, they still need a heat dissipation system to keep the body cool at all times. Some of the best LED plant lights on the market have a heat sink to release extra heat. This means that there are no noisy fans, and no power is wasted by powering them.

7. Lighting coverage

Every LED grow light you consider should contain information about lighting coverage. This refers to the area covered by the light falling on the plant, usually in square feet. A good coverage area is very important. Not only the size and lens of the LED grow light determine your coverage area, but also the height of the suspension. The farther the distance between the lamp and the plant, the larger the area, but the lower the PPFD.

8. Wattage

When it comes to the wattage of LED grow lights, this indicator refers to two things. 550w LED light can show that it can really absorb 550w energy from the wall, or it can provide brightness power equivalent to 550wMH/HID growth light. This also has to be selected according to your planting plants. If it is a more light-loving plant, you can choose a higher power.

When you choose the LED plant growth light, you can choose the best LED plant growth light for your plants by taking the above 8 points as the standard. In terms of minimizing power costs while maximizing plant health, the right LED grow lights will bring you the most benefits.

What are PAR and PPFD in LED plant lights, and why are they rating indicators?

PAR (Photosynthetically Active Radiation) describes the part of the visible spectrum (400nm-700nm) that plants "see" and use for photosynthesis. PPFD (photosynthetic photon flux density) measures the amount of light (PAR) that plants receive over time. PPFD represents the light density received by plants over time, measured in units of micromoles per square meter per second.

PAR (photosynthetically active radiation)

PAR is simply understood as the light suitable for plant growth. Traditional industrial and commercial applications of LED lighting are designed to illuminate the work space for human activities. This means that the only important spectrum is the very narrow central curve perceived by the human eye, and we measure it in lumens. The number of available lumens in a given area is an accurate measurement of the light output and coverage of these applications. The relationship between plants and light is very different, so the way we measure light in gardening is very different.

All plants draw nutrients and growth cues from natural sunlight, and respond to a wider range of lighting chromatograms that humans usually perceive. The spectrum that affects plant growth is in the 400 to 700 nanometer range, involving more red and blue at the end of the spectrum. Because of its positive role in photosynthesis, we call this light photosynthetically active radiation (PAR).

LED plant light manufacturers will advertise the PAR levels produced by their lamps, but there are some other key indicators that accompany the PAR output, which truly separates ordinary light from high-quality LED plant lights.

Photosynthetic photon flux density (PPFD)

PPFD goes one step further. It is good to produce a large area of PAR that nourishes the plant, but if the beam spread is a wide-spreading method, then only a small part of the PAR will actually reach the leaves of the plant. The rest will overflow onto the aisles and walls, which is basically a waste of energy. PPFD measures the density of PAR that actually reaches the plant canopy.

In addition to the high PPFD value, it is important that the light is evenly distributed on the crop. Hot spots or black spots can cause overexposure or underexposure of plants to available PAR and negatively affect the overall harvest quality. This uniformity is a challenge for LED plant lights, but there are some interesting innovations in this field.

The LED plant light produced by Yaorong Technology uses precise optical elements on each diode to focus the beam on the plant and provide precise uniformity throughout the canopy, thereby making the overall harvest healthier. Make sure that the PPFD measurement value you receive from the LED lighting manufacturer is the combined average of multiple measurement points from the entire canopy.

Through the above, we know that the growth of plants is inseparable from the PAR and PPFD in the LED plant light. One can provide the plant with the wavelength and spectrum required for photosynthesis, and the other can provide the light intensity and efficiency required by the plant. The meaning of LED plant lights is to replace sunlight to fill plants with sufficient light intensity and high efficiency. At the same time, the wavelength and spectrum are customized to give plants better growth at each growth stage, so you can see why PAR and PPFD are LED plant lights The rating indicator.

What can be done to give plants better growth?

Regarding how to make plants grow better, we can start from the two points of PAR and PPFD. First, start from PAR, take plants as the object, and customize the LED plant light spectrum that can achieve better growth effects according to the needs of different plants. ,wavelength. It is best to adjust the spectrum of LED plant lights, so that the corresponding spectrum can be adjusted at each different stage, so that the plant grows best.

At this point in PPFD, we need to increase the light intensity and efficiency, and increase the light intensity. We can increase the light intensity of the plants by installing multiple lights to overlap, or adjusting the installation height. The efficiency is the same, so how do we do it?

1. Install evenly distributed

Measure the floor area. Multiply the length by the width to get the square meters of the planting area. You can make the right choice based on how much power to provide per square meter, that is, how many LED plant lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.

2. Illumination distance

The illumination distance of the LED plant light is very important. You have to adjust the points for different plants at different stages, and you must also unify the distance to make the illumination more uniform.

3. Adjust the light

The dimming of LED plant lights can make plants grow better at each stage, the general germination rate: 30%; seedlings: 50%-75%; growth: 75%-100%; flowering: 100%. Give plants the best growth status.

4. Efficient use of light

The LED plant lamp can also realize the efficient use of light under the condition of uniform illumination. The main physical principles used are light reflection and light refraction.

The use of light reflection and refraction not only makes the illumination more uniform, but also achieves high luminous efficiency. The reflector and the metal substrate used by the COB are mainly used. The principle of the reflector reflects the light emitted by the light source into a beam, which increases the local light intensity. The reflection effect is also to maximize the light energy emitted by the LED plant lamp beads to be used by plants, and the reflected part is auxiliary light, which also has the function of fixing the lamp beads and heat dissipation.

Using the principle of light refraction is mainly to use an optical lens. The principle changes the propagation trajectory of the light. Generally, a single lens and a retest lens are used, which can control the light distribution very accurately.

Through this article, I believe that when you choose LED plant lights in the future, you already know which standard to start from. If you want to know more, welcome to Yaorong Technology Consulting.

3 points to pay attention to in LED plant light tissue culture lighting

Now growers will choose to use LED plant lights to fill light. Because the growth of plants can be affected by the control and adjustment of LED plant li.ghts to achieve the effect that growers want, LED plant lights are one of the most important conditions in tissue culture lighting, mainly from light quality, light intensity, light cycle, etc. aspect:

Light quality

The light quality of LED plants lights has a significant effect on the induction of callus, the proliferation of cultured tissues and the differentiation of organs. Like lily bulbs, cultured under red light, the callus differentiated after 8 weeks. The callus will appear only after several weeks of culture under blue light.

15 days after inoculation with gladiolus bulbs, shoots were cultivated under blue light, and the formed seedlings grew vigorously, and the seedlings were slender under white light. The light quality of LED plants lights also has a certain impact on the growth of tissue cultured seedlings. Studies like carnations show that different wavelengths of light play different roles in tissue culture. Blue light helps induce the production of lateral buds and increase protein content. Red light can promote the growth and neat growth of buds.

White light is beneficial to the growth and development of tissue cultured seedlings, with the highest biological yield, followed by red light; blue light promotes the increase of reducing sugar content in stems and leaves, but has little effect on total sugar; white light can also increase the synthesis of chlorophyll. Fan Cihui et al. found that gladiolus globules emerge earlier under blue light than under white light and red light, the seedlings grow vigorously, and the root system is strong; the seedlings are slender under white light, and the number of seedlings under red light is small.

Red light induced callus induction and growth of lily and mung bean better than self-light. If you can consciously apply these LED plant light quality effects to the large-scale production of seedlings, you can achieve the purpose of energy saving and increase production.

Light intensity

Tissue culture LED plant light intensity has an important impact on cell proliferation and organ differentiation. From the current research situation, light intensity has a significant effect on cells and the initial division of cells. , The light is strong, the seedlings grow stout, and the light is weak, the seedlings grow easily. In plant tissue culture, external carbon sources are mainly used as energy sources, and light is mainly used to meet the needs of plant morphology.

The light intensity of LED plant light of 300～500lx can be guaranteed, but for most flowers, 2000～3000 1x is more suitable. In the rooting stage, in order to make the rooting seedlings grow strong and adapt to the field environment as soon as possible, it is necessary to appropriately increase the intensity of the LED plant light to 3000~5000lx, or even 10000lx. If a higher concentration of CO2 is added, the photosynthesis of the seedlings can be enhanced, forcing them to change from heterotrophic to autotrophic, so that the tissue cultured seedlings can grow more robustly.

In order to save costs, in the construction and design of the tissue culture room, you can consider making full use of daylight. "Rooms with better lighting are used as cultivation rooms, and rooms with poor or dark light are used as reagent rooms and cultivation rooms. Some people use greenhouses as cultivation rooms and have also achieved better cultivation results. Using natural light as a light source can reduce Cost of production.

At the same time, since natural light is generally stronger than fluorescent lamps, the cultivated seedlings are relatively short, although the plants grow under strong light. It is relatively slow and slightly green, but due to the accumulation of carbohydrates, the tissue is full and it is easy to adapt to the external environment, and the teleportation survival rate is high.

If it is only beneficial to natural light, it will be greatly affected by the weather. On the one hand, the number of layers and columns in the room and floor are not evenly exposed to light. On the other hand, in clear and cloudless weather, excessive sunlight can burn the seedlings and even die. It is necessary to use thin curtains for proper shading; but under continuous rainy conditions and insufficient light, the seedlings will be weak and long. Fluorescent lights must be installed on all cultivation racks. It needs to be flexibly adjusted to the prevailing weather conditions.

Light period

When the test-tube shoots are cultured in vitro, a certain light-dark cycle is used for tissue culture. The most commonly used time periods are 16 hours bright and 8 hours dark. Studies have shown that organs and tissues of varieties that are sensitive to short sunlight are prone to differentiation under short sunlight. Callus produced under long sunlight sometimes needs to be cultured in the dark, especially the callus of some plants is darker. Light.

Okay, like callus of safflower and black ash. For most plants, 14-16 hours of LED plant light illumination and 8-10 hours of darkness can meet the needs of growth and development. However, different plants and different cultivation purposes sometimes have certain differences. The 12h LED plant light cycle is suitable for chrysanthemum tuber seedlings. Geranium bulimia callus induces bud formation, 15-16h light produces the most buds. If 24h light, the callus cannot turn green and can not produce buds; under 16-18h light, morning glory stem meristem can grow The formation of small plant wipes does not require light all day; under 16h light and long-term darkness, the taro leaves are cut into leaves and seedlings.

In addition, the LED plant light cycle also has a significant impact on the formation and induction of flower buds. Some plants need dark culture during the callus induction period, and light during the differentiation bud stage, such as gladiolus; carnations need dark culture a few days before the cultivation, and then transfer to normal culture, which is conducive to the occurrence of callus; some photosensitive varieties Flower bud differentiation can be induced under light conditions and time.

Advantages of LED plant lights in tissue culture

1. It can be well used in tissue culture, and can be illuminated at close range to provide sufficient light to plants;

2. The wavelength can be customized, which can replace high-pressure sodium lamps, halogen lamps, and fluorescent lamps with 3-5 times the power, saving 80% of electric energy;

3. Long service life, up to 50,000 hours;

4. The ratio of lamp beads can be freely matched to meet the needs of different plants and different growth stages;

5. It can control the growth rate of plants and predict the maturity time of the market;

6. LED plant light is a kind of energy-saving, environmentally friendly and efficient plant growth light.

7. The heat emitted is much lower than traditional plant growth lamps.

8. No standard power socket connectors for drivers or cooling fans are required.

9. Promote early maturity of plants, increase production, and improve the quality of melons and fruits;

10. Ensure the taste of vegetables in greenhouses and realize off-season cultivation;

11. Inhibit the reproduction of germs and pests, and make it green without pollution.

An innovative cultivation method in tissue culture, LED plant lights are also the trend of indoor planting and supplementary light demand. With the continuous progress and development of technology, the two will definitely be perfectly combined to bring better results.

The effect of LED plant light quality and spectrum on indoor crop growth

The effect of LED plant light quality on indoor crops

The light quality of LED plants affects the growth of indoor crop roots. Light can pass through the internal light environment, through the regulation of photoreceptors, and regulate their growth and development. Although there is no direct light, the response to different light quality is also different. The blue light of LED plant lights is conducive to the growth and development of plant roots. Blue light can increase the root vigor, total absorption area and active absorption area of seedlings. The cultivated rice seedlings were irradiated with the blue light of the LED plant light, and it was found that the protein content accumulated in the root system of the rice seedlings was high, the non-protein nitrogen content was low, the ratio of protein nitrogen to total nitrogen was high, and the total nitrogen content was also high. The synthesis of nitrogen compounds in the root system of the seedlings, the production of protein accumulates in the root system. Seedling raising based on the blue light effect of LED plant lights on crop roots has been applied by reproducers.

The effect of LED plant light quality on the growth of indoor crop leaves, leaves are the main organs for photosynthesis of plants, and the change of LED plant light quality directly affects leaf growth. According to reports, the leaf area of birch seedlings grown under blue light is twice that of seedlings under red light, and the area of leaf epidermal cells, palisade tissue, sponge tissue and functional chloroplasts are larger than those under white and red light. The rice seedling experiment has the same result. Compared with white light, blue light can obviously promote the growth of rice seedling leaves, increase the angle between the leaf and the sheath, and make the leaves flat; while the effect of red light is opposite, it inhibits the increase of leaves. Wide growth. However, some people think that the compound light is more conducive to the growth and development of the leaves. The leaf area of lettuce under the combination of red, blue, and green light is extremely large, followed by white light, and red and blue light. Studies have also shown that increasing the proportion of LED red light in the compound light has a certain promotion effect on the increase of tobacco leaf area, but the leaf weight of the leaf is reduced, and the leaf becomes very thin.

The effect of the light quality of the LED plant light on the growth of indoor crop stems. Different wavelengths of light can regulate the growth of the stems by affecting the level of endogenous hormones in the plant. Blue-violet light can increase the activity of indole acetic acid oxidase and reduce the level of auxin, thereby inhibiting the growth of plants. At the molecular structure level, red light can promote cell elongation, while blue light has the opposite effect. The long-wavelength LED plant light red light promotes the elongation of the stem, while the short-wavelength light inhibits the elongation of the stem.

The effect of LED plant light spectrum on indoor crops

UV spectrum (100–400 nm)

The ultraviolet spectrum that is invisible to the human eye is outside the PAR range (100nm-400nm). Approximately 10% of sunlight is ultraviolet light. Just like humans, plants can be harmed by excessive exposure to ultraviolet light. Divided into 3 types, UV-A (315-400 nm), UV-B (280-315 nm) and UV-C (100-280 nm).Although the benefits of using ultraviolet light in indoor cultivation are still being researched, ultraviolet light usually leads to a deeper purple-in fact, a small amount of ultraviolet light can have a beneficial effect on color, nutritional value, taste and aroma.Studies have shown that using controlled amounts of ultraviolet light can also reduce environmental stress, fungi and pests. Studies have shown that the use of UV-B light (280 nanometers to 315 nanometers) can increase the cannabinoids such as tetrahydrocannabinol in cannabis.

Blue light spectrum (400–500 nm)

The blue light spectrum is widely responsible for improving plant quality—especially in leaf crops. It promotes stomata opening-allowing more carbon dioxide to enter the leaves. Blue light drives the peak absorption of chlorophyll pigments required for photosynthesis.This is essential for seedlings and seedlings in the vegetative stage, as they will establish a healthy root and stem structure-especially important when stem extension must be reduced.

Green light spectrum (500–600 nm)

Compared with the red or blue spectrum, the green wavelength is less important for plant photosynthesis because it (not) easily absorbs chlorophyll. Nevertheless, green is still absorbed and used for photosynthesis. In fact, only 5-10% is actually reflected-the rest is absorbed or transmitted to a lower place! This is because green light can penetrate the canopy of plants,In the greenhouse, due to the presence of sunlight, the use of LED grow lights to supplement the green light spectrum is less important than crops that are only grown indoors (such as hemp or vertical crop cultivation).

Red light spectrum (600–700 nm)

Red light is the most effective spectrum for promoting photosynthesis because it is highly absorbed by chlorophyll pigments. In other words, it is located at the peak of chlorophyll absorption. The wavelength of red light (especially around 660nm) promotes the growth of stems, leaves and general vegetative growth-but the most common is the tall extension of leaves and flowers.It must be balanced with blue light to counteract any excessive stretching, such as deformed stem elongation. It is important to consider that although red is the most sensitive spectrum to plants, its efficacy will really come into play when combined with other PAR wavelengths.

Far-red light spectrum (700-850 nm)

Far-red affects plant growth in several ways-one is to initiate the shade avoidance response. At about 660nm (dark red), plants will feel bright sunlight. From 730 nanometers and above-that is, the ratio of far red light to red light is higher, the plant will detect the light "shadow" from another plant or a leaf higher in the canopy, so stem and leaf stretching will occur.

Far-red is very useful for promoting flowering and can increase fruit yield in some plants. In short-day plants like cannabis that rely on longer periods of darkness, 730nm can be used at the end of the photoperiod to promote flowering. Many growers are trying to use bursts of red light to interrupt the cycle of darkness to promote growth and flowering.

LED plant lights bring opportunities for the development of vertical agriculture

Vertical agriculture is a revolutionary and sustainable agricultural method that does not require so much space and water demand, and has no impact on the ecological environment. However, the demand for light has never changed, so LED plant lights are needed to supplement light. The emergence of LED plant lights brings unlimited possibilities for the development of vertical agriculture.

Why is there vertical agriculture?

In a linear system, feeding the urban population is particularly challenging. Agriculture is limited by the amount of space for growing crops. This may limit the total output of the farm, making it difficult to expand and produce more food. This is also the reason for the emergence of vertical agriculture. Vertical agriculture is carried out indoors, eliminating the possibility of environmental damage such as weather, pests and diseases. This agricultural method ensures that all plants receive the same amount of light, water and nutrients.

"LED plant lights in agriculture will be ubiquitous, and all fields of modern agriculture are closely related to light," said Yang Qichang, a senior expert in the field of agriculture and a researcher at the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences. The planting industry of modern agriculture ( For example, facility gardening, urban agriculture, open field production, plant protection and trapping, etc.), livestock and poultry breeding, aquaculture, and other (edible fungi, microalgae, etc.) all require artificial light sources to supplement light, so the role of LED plant lights will increase. Bigger.

The LED plant light can be designed to emit a specific wavelength of vertical agricultural planting light source, which can be used as an alternative light source for sunlight. Plants do not use the entire spectrum. Plants mainly absorb only part of the spectrum. The peak wavelength of chlorophyll absorption is about 450 nanometers and 650 nanometers (blue and red, respectively). Vertical agricultural growth lights using LED plant lights can be designed to emit only these wavelengths, thus providing only the light needed by plants.

We can know from the above that the growth of plants has nothing to do with soil. What plants need is light. The development of vertical agriculture is to break through the limitation of land space. As long as the light demand is met, plants can grow.

The following are several innovative cultivation methods for vertical agriculture:

1. Hydroponics

Hydroponics is a new method of plant cultivation, and it is also the most widely used method in vertical agriculture. This method does not require soil, but uses nutrient solution to cultivate, which is more convenient to cultivate and the plants are safer.

2. Aerosol cultivation

Aerosol cultivation technology is a new type of cultivation method. Aerosol cultivation is similar to hydroponics. The difference is that the nutrient solution is atomized and sprayed directly onto the roots of plants in the form of spray to provide the water and nutrients needed for plant growth. , And there is the ability to reduce water consumption.

3. Fish and vegetable symbiosis

The fish and vegetable symbiosis system is very similar to the hydroponic system, but one more is to integrate fish and plants together and use each other. The water purified by the plants is used for the fish ponds, and the waste generated by the fish can serve as the nutritional needs of the plants. .

4. Lokal-a self-sufficient small household vegetable system

Lokal technology is the combination of hydroponics and LED plant lights. Nutrient solution replaces soil and LED plant lights replace sunlight, so that plants can also be grown indoors without being restricted by environmental or geographical conditions.

5. AeroFarms-Intelligent Vertical Agriculture Innovation

AeroFarms technology combines the latest technologies such as LED plant light supplement light, aerosol cultivation technology and climate control to control and regulate various factors in line with the growth of plants, giving plants the best growth environment, but the investment cost may be higher. But now there are many successful cases abroad.

Features of LED plant lights:

1. Increase yield: The energy needed for plant growth comes from the photosynthesis of plants, and photosynthesis requires sunlight, and LED plant lights can supplement light to plants when the light is insufficient, and promote the accumulation of plant dry matter, thus achieving the purpose of increasing yield. .

2. Early market: LED plant lights can shorten the growth cycle of plants, promote the growth of plants, can make crops go on the market 7-15 days in advance, greatly increasing the economic income of users.

3. High luminous efficiency: 90% of the light emitted by LED plant lights can be absorbed by plants. Traditional plant lights such as high-pressure sodium lamps and metal halide lamps can only absorb 8-10% of the light during photosynthesis.

4. Low power consumption: LED plant lights consume very little power, so users do not have to worry about the cost of supplementary lights.

5. Long lifespan: LED plant lights have an extremely long lifespan, with an ultra-long lifespan of 50,000 hours to ensure long-term safe and efficient operation of the product.

6. Environmental protection: LED plant lights are safe, environmentally friendly and do not contain toxic mercury. Our LED grow lights use 10%-30% more energy than traditional lights. Consuming less energy can reduce greenhouse gas emissions into our environment.

Vertical agriculture is growing as an increasingly accepted mode of production. These innovative technologies will become more and more popular and will completely change the face of agriculture in the future! The development of agricultural planting is inseparable from light, and the same is true for vertical agriculture, and most of them are indoor planting, so it is natural to need supplementary light. LED plant lights are now the most popular plant supplement light for indoor planting. The development of vertical agriculture will bring a wave of new markets and opportunities to LED plant lights.

Application of LED plant lights in hydroponic cultivation

With the development of technology, indoor planting has developed soilless planting, hydroponic planting and other planting methods, which not only improve the utilization of land and water and fertilizer, but also promote the vigorous development of agriculture.

Hydroponic cultivation is to create a relatively closed environment that can store nutrient solution through specific facilities, and keep the water, fertilizer, gas, heat and other conditions required for root growth relatively stable, and all or part of the root system is "immersed" in the nutrient solution. Cultivation methods.

When planting indoors, LED plant lights can be used to supplement light during hydroponic cultivation. LED plant lights are made according to the absorption and utilization of sunlight by plant growth, and the spectrum and light intensity meet the requirements. It can be used to supplement light for vegetables, seedlings, fruits, and flowers. It can not only promote the progress of photosynthesis, but also achieve the effects of increasing production and increasing, launching in advance, and enhancing quality.

Advantages of LED plant lights in hydroponics

1. It can be well used in hydroponic cultivation, and can be illuminated at close range to provide sufficient light to plants;

2. The wavelength can be customized, which can replace high-pressure sodium lamps, halogen lamps, and fluorescent lamps with 3-5 times the power, saving 80% of electric energy;

3. Long service life, up to 50,000 hours;

4. The ratio of lamp beads can be freely matched to meet the needs of different plants and different growth stages;

5. It can control the growth rate of plants and predict the maturity time of the market;

6. LED plant light is a kind of energy-saving, environmentally friendly and efficient plant growth light.

7. The heat emitted is much lower than traditional plant growth lamps.

8. No standard power socket connectors for drivers or cooling fans are required.

9. Promote early maturity of plants, increase production, and improve the quality of melons and fruits;

10. Ensure the taste of vegetables in greenhouses and realize off-season cultivation;

11. Inhibit the reproduction of germs and pests, and make it green without pollution.

Significance of Hydroponic Plants

1. Adapt to market demand

Annual cultivation can be carried out on the same site. Leafy vegetables are not easy to store, but in order to meet market demand, annual production is required. Hydroponic cultivation is very simple. You only need to plant seedlings in the planting holes. For example, lettuce can be sown, planted, harvested at any time, and produced continuously without interruption, so hydroponics is suitable for planned and contracted production.

2. Solve the problem of anti-seasonal supply of vegetables

Hydroponic vegetables have a short growth cycle, and the hydroponic method belongs to facility production, which is generally not easily damaged by natural weather. Planted throughout the year, fresh vegetables can also be supplied in off-season to obtain higher profits.

3. No need to change the nutrient solution midway

No need to change the nutrient solution midway. Due to the long growth period of fruits and vegetables, even if there is no major physiological disease, in order to ensure the balance of nutrients in the nutrient solution, it is necessary to renew the nutrient solution in half or full amount.

4. High economic benefits

Hydroponic leafy vegetables can avoid continuous cropping obstacles, and the multiple cropping index is high. The facility operation rate is as high as 20 crops a year, and the production economic benefits are high. For this reason, generally leafy vegetables are often carried out by hydroponics.

Attention should be paid to the LED plant light hydroponic supplement light:

Appropriate lighting time

In terms of the duration of light, most plants have a natural circadian rhythm. This can also be imitated with the artificial light in the greenhouse. There is already a greenhouse lighting system, which can be programmed with the timer function, so that the LED plant light can slowly fall on the plants like nature.

Appropriate light intensity

The light intensity depends on the photon flux density, that is, how many photosynthetic photons are in the radiation. It can be quantified as micromoles per square meter and second (μmol/m2s). For comparison: Direct solar radiation up to 2,000 μmol/m2s. Your greenhouse plants usually don't need as much light. As the guiding principle of light intensity in artificial greenhouse, 600μmol/m2s is enough to achieve good growth.

Reasonably distribute the light evenly

Measure the floor area. Multiply the length by the width to get the area of the hydroponic area in square meters. You can make the right choice based on how much power to provide per square meter, that is, how many LED plant lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.

Appropriate light color

Light travels from the sun to the earth as electromagnetic waves of different wavelengths. The wavelength range visible to the human eye is between 380 and 750 nanometers (NM), which roughly corresponds to the light that plants can use for photosynthesis. The wavelength of light determines the so-called light color. The short wave turns blue, and the long wave turns red. Light waves around 500 nautical miles are green and reflected by plants. This phenomenon is also called green space because less photosynthesis can be used to use green light. You should not rely on greenhouse lighting that only combines blue and red light without any green part, because it is still very common. Because this can shut down the weaker photosynthesis and complete plant growth under green light.

Vertical agriculture is the trend of future agriculture. Hydroponic cultivation is an innovative cultivation method in vertical agriculture. LED plant lights are also the trend of indoor planting to supplement light. With the continuous advancement and development of technology, the two will definitely be a perfect combination. Vertical agriculture and LED plant lights promote the development of each other.

Indoor plant grow lights: who has the advantage of LED, CFL, HPS

As an indoor grower, you will definitely consider which plant growth lamp you choose to fill up your plants with the best light. Light is the key element of plant photosynthesis, the correct choice of plant growth light will greatly promote the growth of plants. Generally choose from these points: initial cost, later cost, spectrum, efficiency and rate of return. Let's compare which of the LED, HPS, and CFL has the advantage?

LED plant light (LED)

The operation of LED plant lights is much more complicated than the old technology: small diodes doped with semiconductor materials are energized with a constant current. By using the optical properties of different materials, we can obtain different colors.

Although the operation seems more complicated, the technology has been able to gain a foothold in the market thanks to its high reliability, excellent efficiency and lower cost. LED plant lights do not contain toxic gases, so the most important thing is the environment.

LED plant lights come in different sizes and wattages, revolutionizing the gardening market by allowing the creation of more and more effective lighting solutions with increasingly complex spectrums.

Some manufacturers of indoor LED plant lights mistake growers for the victims of improper marketing. They sell any color other than red or blue as a color that is useless and unusable for plants. They put forward skeptical graphics, indicating that the green light is completely reflected by the leaves, and that they provide you with the most effective products, but the growers may suffer.

However, LED plant lights have "almost twice the efficiency of traditional high-pressure sodium lamps and CFL bulbs (up to 2.6umol/J), especially full-spectrum LED plant lights. The efficiency of the light source and the lack of infrared make most LED lights hardly dissipate heat. , Which is conducive to controlling the temperature of the growth chamber and reducing the cost of pumping. All of these will ensure that you get a good harvest with less electricity.

The cost is certainly high, but the duration and efficiency of the system will give you more or less time to recover your investment.

Fluorescent lamp (CFL)

CFL fluorescent lamps allow us to replace old incandescent bulbs that generate more heat than light. The operation is conceptually similar to the HPS technology: the bulb consists of a high-pressure glass tube filled with mercury and rare gases and two electrodes that can generate ultraviolet light that is powered by an electronic ballast. Then, the light passes through the phosphor that covers the glass tube and is converted into white light.

These bulbs are also available in various sizes and wattages, and because of their low calorific value, they are widely used for professional and home planting. The spectral quality is acceptable, but the system has many limitations: the emitted light is never too strong to bloom, and the electrical efficiency is lower than that of the HPS system; for the best brands, it is about 1.3umol/j.

CFL bulbs are still very suitable for providing low-power light sources in the early plant and cloning stages, providing easy-to-use low-heat solutions. Plants can also grow in contact with the bulb without being burnt.

These lamps are cheap and have a long service life (approximately 10,000 hours of light). Our system is recommended to growers who need to economically solve plant growth stage problems.

High Pressure Sodium Lamp (HPS)

The high pressure sodium lamp (HPS) is undoubtedly the most popular and extensively tested lamp that can be used in various cultivations. These glass bulbs usually have a wattage of 50 to 1000 watts and contain pressurized gas that is ionized by two electrodes to produce photons.

High-pressure sodium lamps (HPS) produce a significant proportion of ultraviolet and infrared (approximately 20%): these frequencies help to simulate the solar spectrum, but are almost completely converted into heat. This requires a proper extraction system. The grower must be careful not to burn the growing leaves to the light. At the same time, excessive heat generation will also cause additional costs.

On the other hand, the rich green and yellow spectrum allows the light generated by these special lamps to penetrate the leaves, which is difficult to achieve with other systems. So they are usually installed on a fixed height ceiling.

Consumption and cost

The high pressure sodium lamp (HPS) has been around for a long time and works well, so many "loyal" growers will not replace it with other products.

The initial cost of the HPS system with power supply and reflector is not high (a complete set of 600W kit is about 150 euros), but the HPS bulb wears out very quickly, so the intensity will drop after a few months, and there will be a bulb to replace it, and later investment The cost will increase.

We recommend using these systems for growers who occasionally hope to spend less money in the short term but still get satisfactory results, especially those who live in cold regions. Let the excess heat be an advantage rather than a defect.

Yaorong LED plant growth light, the product characteristics of LED light (LED plant growth light) can replace traditional lights 3-5 times the power, saving 80% of the electric energy;

LED is used as the light source. And the life span is up to 50,000 hours;

The ratio of different lights can be specified by the customer. We recommend the ratios (red: blue) 8:1, 7:2 and 7:1:1, red. Provide plants with blue, orange, white and yellow mixed light;

The LED wavelength can be specified by the customer. We recommend using 620-630nm and 640-660nm for red wavelengths and 450-460nm and 460-470nm for blue wavelengths. Red light helps plants germinate and bloom, while blue light helps plants grow. You can choose a more suitable wavelength and color ratio to promote plant growth;

Very suitable for all stages of plant growth lights, they are suitable for indoor gardens, aquatic plants or soil-growing plants;

The area and height of the lamp will change according to different plants and environments, and the technical parameters will also change;

All material rings of the product meet environmental protection requirements and do not contain harmful heavy metals such as mercury;

Imported chip LED with high brightness and high reliability as the light source, with high brightness, wide angle and uniform light;

DC12V low voltage drive, safe to use;

Low power consumption, long life, maintenance-free;

Different plants require different growth conditions, and the wavelength of the light source required to participate in plant photosynthesis and affect germination and flowering will also be different. Therefore, the working wavelength of the product and the ratio of light source components will be very different for different plants. It can be customized according to user requirements, or the user provides relevant information, and we determine the composition of the light source for the user. Generally, red and blue light are the main components, and the ratio of red and blue light ranges from 2:1 to 9:1;

Red light: Promote photosynthesis of chlorophyll A and chlorophyll B, promote the formation of plant stems, stems and roots, leaf bulbs and other plants, and affect flowering and fruit;

Blue light: promote plant photosynthesis, promote green leaf growth, protein synthesis, fruit formation, increase yield and shorten the incubation period;

Customers can choose a more suitable wavelength and color ratio to promote the growth of plants according to the needs of your cultivated crops.

LED plant lights affect the growth of seedlings

Plants need sunlight during the important process of photosynthesis to produce starch, sugar and other substances needed for development. If there is insufficient light, the plants grow slowly and are very susceptible to diseases and pests. Their goal is to obtain strong and vigorous seedlings that can bring good harvests.

LED plant lights used for seedling cultivation are highly efficient and durable. The spectrum of the entire system can be adjusted very simply because the needs of seedlings will change significantly as they grow.

Before picking the seedlings, the light from the blue and red LED plant lights set at a ratio of two to one can be better perceived. The rich blue here activates the growth of the root system, but slightly inhibits the extension of the ground part. The stems are strong, with frequent internodes.

After picking, it is best to reduce the light intensity for a few days to ensure a rest after the stressful transplant. Next, you need to illuminate the seedlings with blue and red LED plant lights at a ratio of 1:1.

The effect of LED plant lights on vegetable seedlings

LED plant lights can regulate the light morphology and growth of plants and have an important impact on vegetable seedlings. Photomorphogenesis means that plants rely on light to control cell differentiation, structure and function changes, including effects on the germination of some seeds, promotion of upward growth, inhibition of lateral bud growth, stem elongation, and tropism. Therefore, indoor planting with LED plant lights can better regulate the growth of vegetable seedlings, flower bud differentiation and flowering, and better growth conditions will bring earlier harvests and increased yields.

Generally, auxin is used to regulate the growth of vegetable seedlings, but vegetable consumption is detrimental to people's health. LED plant lights make the seedlings grow better through spectrum adjustment through unique light supplement advantages, green light promotes the elongation and growth of cucumber seedlings, red light and blue light inhibit seedlings from growing, and compared with monochromatic light quality, it contains red The index of strong seedlings increased under the compound light supplement light treatment of the blue component.

Red supplementing cucumber seedlings with LED plant lights can increase the chlorophyll a, chlorophyll b and carotenoid content of cucumber seedling leaves; LED plant lights with red light and blue light can significantly increase the leaf area, dry matter quality and seedling index of tomato seedlings, and supplement the LED red light , Green light significantly increases the plant height and stem thickness of tomato seedlings. The red and blue combination of LED plant light can increase the stem thickness, leaf area, dry weight of the whole plant, root-to-shoot ratio, and seedling index of the eggplant. The red light energy of LED plant light Increase the biomass of the cabbage seedlings and promote the elongation of the cabbage seedlings. The blue light of the LED plant light promotes the thick growth, dry matter accumulation and strong seedling index of the cabbage seedlings. In this way, we know that the LED plant light regulation technology has a very obvious effect on the growth of vegetable seedlings.

The effect of LED plant light quality on the proliferation of tissue cultured seedlings

Studies have found that red light in monochromatic light can promote the proliferation of tissue cultured seedlings. Compared with the control fluorescent lamp, the number of single buds of the Phalaenopsis under the pure red LED plant lamp increased significantly, and the experiments of chrysanthemum and tobacco also reached similar conclusions. A single blue light is not conducive to the proliferation of tissue cultured seedlings. In the study of eustoma and sugarcane tissue culture seedlings, it was found that among all light quality treatments, the tissue culture seedlings under the monochromatic blue light treatment had the lowest growth coefficient. However, blue LED plant lights can effectively promote the formation of Phalaenopsis protocorm.

Experiments have shown that, compared with monochromatic LEDs, different combinations of LEDs are more conducive to the proliferation of tissue culture seedlings. The combination of red and blue LED plant light can promote the proliferation of sugarcane adventitious buds better than monochromatic light, which is better than fluorescent light and plant growth light. The regeneration effect of the adventitious buds of Rhododendron alpina leaves under the combined treatment of red and blue light is significantly better than that of 100% red and blue light. However, different plants or different varieties of the same species have different requirements for the light quality ratio at the stage of tissue culture proliferation. Rhododendron alpine leaves the best regeneration effect of adventitious buds under the treatment of red and blue light (3:1).

The effect of LED plant light quality on the growth of tissue cultured seedlings

Studies have shown that the effect of LED monochromatic light on the growth of tissue cultured seedlings is lower than that of different LED combined lights, while red and blue LED combined lights can enhance plant photosynthesis and promote plant growth and development. The growth of white palm tissue culture seedlings treated with a single red or blue LED is poor, and a certain proportion of red and blue LED compound light is beneficial to promote plant growth. The net photosynthetic rate of chrysanthemum tissue culture seedling leaves under the combination of red and blue light was significantly higher than that of monochromatic red and blue light, and the fresh weight and dry weight of the plant reached the maximum. The fresh and dry weight of strawberry sugar-free tissue culture seedlings was the smallest under blue light.

The optimal ratio of red and blue LED plant lights grown in tissue culture seedlings is inconsistent with the research conclusions of different plants. Japanese double butterfly and strawberry tissue cultured seedlings grow best under 70% red light + 30% blue light. However, the growth index of Anthurium andraeanum tissue culture seedlings under the treatment of 50% red light + 50% blue light was significantly higher than that of the control. Red light (R) treatment of white and tissue culture seedlings grow, blue light (B) treatment of white and tissue culture seedlings are low, compound light is conducive to the growth and morphology of white and white; 1RB light source treatment of white and tissue culture seedlings have significant soluble sugar content Higher than other treatments; in tissue culture production applications, adjusting the optimal red and blue ratio is the key to producing high-quality tissue culture seedlings.

The effect of LED plant light quality on the rooting and strong seedlings of tissue cultured seedlings

The effect of light quality on the induction and growth of isolated plant roots varies with the wavelength, and the effect of light quality depends on the plant genotype and rooting material concentration. Red light promotes the formation of adventitious roots of anthurium, phalaenopsis, imperial flower and ground cover chrysanthemum tissue culture seedlings. It is characterized by fast and dense rooting, and blue light has a significant inhibitory effect. Papaya tissue-cultured seedlings have the shortest root length under blue light; red and blue mixed light can promote the growth of sweet potato tissue-cultured seedlings to a certain extent. However, the root morphology of the tissue cultured seedlings under monochromatic red light is abnormal, and the survival rate of transplantation is low. Blue light helps to improve the vigor of the root system in the later stage, promote the accumulation of dry matter, reduce the water content, and prevent the vitrification of plants. Monochromatic red light irradiated the root system of chrysanthemum with low vigor, and the survival rate of transplanting was only 75%, while the transplanted tissue cultured seedlings survived under the combination of red and blue light. The root length and root vigor of Phalaenopsis treated with LED plant light and far red light were significantly increased compared with the control. Oncidium tissue culture seedlings have the longest root length under the combination of red and blue light, and the shortest root length under fluorescent light. Monochromatic red light irradiated the root system of chrysanthemum with low vigor, and the survival rate of transplanting was only 75%, while the transplanted tissue cultured seedlings survived under the combination of red and blue light. The root length and root vigor of Phalaenopsis treated with LED plant light and far red light were significantly increased compared with the control. Oncidium tissue culture seedlings have the longest root length under the combination of red and blue light, and the shortest root length under fluorescent light. Monochromatic red light irradiated the root system of chrysanthemum with low vigor, and the survival rate of transplanting was only 75%, while the transplanted tissue cultured seedlings survived under the combination of red and blue light. The root length and root vigor of Phalaenopsis treated with LED plant light and far red light were significantly increased compared with the control. Oncidium tissue culture seedlings have the longest root length under the combination of red and blue light, and the shortest root length under fluorescent light. The root length and root vigor of Phalaenopsis treated with LED plant light and far red light were significantly increased compared with the control. Oncidium tissue culture seedlings have the longest root length under the combination of red and blue light, and the shortest root length under fluorescent light. The root length and root vigor of Phalaenopsis treated with LED plant light and far red light were significantly increased compared with the control. Oncidium tissue culture seedlings have the longest root length under the combination of red and blue light, and the shortest root length under fluorescent light.

The LED plant lights used in the tissue culture stage will affect the growth and survival of the tissue culture seedlings after being transplanted outdoors. The indoor tissue culture stage uses a combination of red and blue LED light sources, which can increase the survival rate of strawberry, white brown, and chrysanthemum tissue culture seedlings, and promote the growth of seedlings after transplantation. Therefore, for plant tissue culture seedlings that are difficult to root, the rooting rate and root number can be increased through the pretreatment of red light in the early stage, and then adjusted to a certain proportion of red light, blue light and high beam. Cultivation uses red light to promote the growth and development of root system, improve root system vigor, and improve the adaptability of tissue culture seedling transplanting.

5 product advantages of LED plant lights

LED plant light is a kind of high-efficiency and energy-saving lighting fixture, which has the potential to fundamentally change the supplementary light of plant lighting in the future. However, the lighting technology of LED plant lights is not universal. There are low-power and inferior low-cost LED plant lights on the market, but they are advertised and sold with various false advantages. Many customers have also suffered in this respect. Today, Yaorong Technology is here to tell you about the 5 product advantages of LED plant lights.

Less consumption, more energy saving

LED plant lights are more energy-efficient than traditional lamps with very high operating temperatures, such as HPS and metal halides. Most of the energy consumed by these traditional lamps is used for thermal radiation (infrared radiation). Plants do not use infrared photons in photosynthesis, but they can warm plants and the environment. When using HPS and other traditional lights in warm climates or just installing many fixtures in one area, plants can easily overheat, causing you to need additional ventilation. The power consumption of fans and air conditioners will add more energy to your planting facilities.

LED plant lights are not just a substitute for HPS lights. HPS and other HID lights cannot be placed close to plants without burning them. Although LED plant lights generate heat like all electronic devices, their operating temperature is much lower. Their light does not emit heat radiation. They can be placed close to the plant canopy, saving space and reducing energy and infrastructure requirements.

The structure of the LED plant growth lamp emits light as a downward beam. Traditional plant lights emit light in all directions, so shades and reflectors are needed to guide the light to the plants. This kind of equipment increases the volume and is not efficient in directing light to the plants, which indirectly increases energy consumption. High-quality LED grow lights are equipped with secondary optical elements. This helps to avoid "hot spots" and distribute the light evenly in the growth area. They also ensure that the photons are delivered directly to your crop.

An Energy Report of the US Department of Energy researched the energy-saving potential of LED lighting in horticultural applications and found that LED plant growth lamps provide a 24% to 30% reduction in power consumption, which is more energy-efficient than other lighting fixtures.

Low heat generation and easy management

LED plant lights do generate heat in semiconductors. But because LED grow lights do not have filaments, they are generally more effective than HPS light sources in this regard, and therefore generate less excess heat in indoor greenhouses.

Proper thermal management is essential for LED grow lights, because the increase in heat will have a negative impact on the performance of LED grow lights, including reduced light efficiency, color shift and shortened lifespan. Because LED grow lights produce very little heat, growers can use a small and reliable extraction system to handle the excess heat, so there is no need to spend a lot of time, effort or expense to deal with the excess heat.

Longer service life

LED manufacturers' claims about the lifespan of LED plant lights obscure the real product failure mechanism and mislead customers. The life expectancy of most LED grow lights is rated between 50,000 and 100,000 hours. In contrast, many other grow lights tend to last about 20,000 hours before they need to be replaced. In addition to reducing long-term replacement costs, you can also save money by reducing maintenance costs and improving energy efficiency, while using longer-life lamps to improve light quality. The research report pointed out: LED lighting has surpassed all traditional lighting technologies in terms of energy efficiency, life span, versatility and color quality.

Operating temperature is also a major factor in the life of LED plant lights, so management attention is needed.

Increase crop yield

LED plant light technology cannot provide the same output as HPS and other HID technologies. LED plant light technology has the ability to increase yield, speed up production time and improve crop quality for today's growers. With its customizable spectrum, higher yields are achieved due to the high-quality spectrum and light output that better penetrates the plant canopy.

At the same time, LED plant lights can be used to control the photoperiod of plants, so that they can be harvested several times a year. If you want to increase the light on plants and give them better light conditions, they can make plants grow better. Better harvest.

High return on investment

The cost of LED plant lights is enough to justify the investment, but it depends on one's ultimate goal, and the cost is only part of the equation. Commercial growers seek long-term solutions. Appropriate LED plant lights can meet the needs of investors and operators many times. Although LED plant lights may require higher capital expenditures (assuming no subsidies, leases or incentive plans), LED plant lights (with an expected life span of 50,000 hours) provide a comparable service life, if not significantly better than HID systems .

Compared with traditional HID lighting technologies such as HPS and MH, LED plant lights can directly and indirectly save costs. The direct savings come from the higher efficiency of the LED plant light, which uses less wattage to obtain a higher or similar level of light.

Advantages of LED plant lights in the later stage:

Lower maintenance costs: There is no need to disassemble the LED grow lights for repair or cleaning, and most diodes have a rated service life of more than 50,000 hours.

Fewer consumables: LED plant lights do not need bulbs, ballasts or drivers to be replaced.

Less water: As plants evaporate less, the evaporation of soil or media is reduced.

Lower cooling requirements: LED plant lights radiate very little heat, so energy is not wasted to cool the space and plants.

Reduce infrastructure requirements: LED plant lights can be placed close to plants, so the infrastructure can be smaller and more economical.

The technology of LED plant lights is constantly improving to bring better growth to plants with better supplementary light. People should also pay special attention when choosing. Don't listen to the suppliers' excessive bragging about product advantages. When encountering this, you can doubt it, and make a better judgment from a more perspective before making a choice.

Advantages and disadvantages of indoor planting of LED plant lights

LED plant grow lights are one of the most promising supplementary lighting types for indoor planting. Let us understand this in more detail, because this LED plant grow light has many advantages compared with other traditional plant lights, and because it is indoor planting A new stage of agricultural development.

Plant growth process: From simple molecules, a huge organic chain is constructed to form the plant itself. For any process, energy is needed, and in real life conditions, plants use sunlight to obtain energy. A photon enters the leaf and initiates a biochemical reaction. The result is an increase in weight-roots, stems, leaves and fruits develop. The process of combining the atoms of simple mineral molecules into more complex organic molecules that occurs under sunlight is called photosynthesis. No light means no photosynthesis, and no plants without photosynthesis.

Therefore, indoor planting needs LED plant lights, and it is necessary to figure out the benefits of LED plant lights to plants. Let's take a look at the important role of LED plant lights in plant growth. Let’s take a look at the advantages and disadvantages of indoor LED plant growth lights:

Advantages of LED plant lights

Energy saving

LED grow lights are more efficient than traditional lighting systems and can reduce energy by 60% to provide the same level of light. Compared with traditional lighting systems, they emit less heat and provide more usable light. This is because LED diodes will not burn anything to produce light. Due to reduced energy use and heat production, LED plant growth lights greatly reduce energy costs.

More efficient

Compared with HID lighting, growers who use LED plant lights to grow plants in indoor planting will talk about the efficiency of this lighting system. LED plant lights are actually more efficient than HID lights, which means you will bring higher benefits.

Low temperature

The operating temperature of LED plant lights is significantly lower than that of HID bulbs. The HID system can become very hot, putting crops at risk of thermal damage, and may even cause a fire when used in a small space.

Longer life

LED plant lights not only provide higher efficiency and lower temperature. You can also get more growth time from LEDs—more. LED grow lights usually last 50,000 hours or more, while HID bulbs usually last 10,000 to 18,000 hours, depending on the specific type of bulb. When it comes to longevity, there is really no competition.

Full spectrum

One of the main advantages of using LED grow lights is that they provide a wide range of energy. When you choose LED, you don't have to worry about turning off the light when the crop growth cycle is mature. Even better-you can actually install a system tailored specifically to the type of crops you grow.

Fast harvest cycle

The LED grow light can be used 24 hours a day, and it has little effect on temperature. When growing plants indoors, the lack of environmental feedback means that plants rely on you to tell them what season it is and how they should behave. The use of LED plant growth lights enables you to change the time of day and the amount of light of red wavelength at the correct time to maximize the growth rate of plants. When LED grow lights are used to grow automatic flowering plants, there may be multiple harvests in one season. You can change the flowering time of the plant and increase the yield.

Disadvantages of LED grow lights

The fact is that, like any type of artificial light, LED plant growth lights have disadvantages. These disadvantages include:

Blue light

good for plants, good for you Harmful Your crops thrive in light at the blue end of the spectrum, especially when they are in the vegetative stage. On the other hand, your eyes? Not that much. Prolonged exposure to blue light (a type of light emitted by LED bulbs) can damage your retinal cells.

High initial investment cost

Many growers are turned away by the high upfront costs associated with LED lights. Purchasing an LED system means a larger initial investment than a similarly powered HID system, but a little mathematical calculation shows that in the long run, you will actually save money due to the high efficiency of LED.

So, is LED light the best choice for indoor planting?

As you know, there are definitely some advantages to using LED systems, but whether they are the best choice for indoor cultivation depends on several factors. For many growers, the low temperature, efficiency, lifespan, size and spectrum of LED make them ideal for indoor cultivation. Other growers, usually those who perform large-scale operations, prefer HID lights because they provide the strongest light. Of course, HID also have their own challenges-they consume more energy than LED, and they also force growers to invest in additional equipment, such as protective covers and exhaust fans. However, if your main goal is to maximize the number of crops your garden produces, then HID may be the way to go.

LED grow lights are almost certainly the future of the gardening industry. Even today, higher costs are the only serious disadvantage. As prices fall, this shortcoming is quickly disappearing. The best LED grow lights are very effective, and they can easily surpass any other type of garden lighting on the market today.

4 ways to increase cannabis production with LED plant lights

Almost all indoor cannabis growers hope to obtain higher yields with less money, time and energy. If you still don’t know how to increase the production of indoor cannabis? No measures have been taken, then please consider that you have one last chance. I will introduce 4 simple methods for LED plant lights to increase indoor cannabis production. These 4 tips and strategies will help increase your indoor cannabis production.

Increase the intensity of LED plant lighting

One of the most important things to do from the beginning is to make sure your cannabis gets enough light. During the vegetative phase, cannabis plants that do not receive enough light tend to "stretch" toward the light, with many stems between the nodes and the leaves. So it is necessary to provide enough light intensity to prevent young cannabis plants from stretching or growing too high and falling.

When your marijuana plant sprouts buds, you can take any measures to help direct more intense light to the buds, which tends to increase your yield. Then use LED plant lights to fill the cannabis light, choose a higher-power lamp or reduce the distance between the LED plant light and the cannabis plant, and maximize the light intensity to fill the cannabis light.

When your marijuana reaches the maximum amount of light to fill up the light, you can also have techniques to further increase the yield. You can increase the level of carbon dioxide in the growth chamber during the flowering phase of the hemp to enable your hemp to use more light and further increase bud production.

Enhance the uniformity of LED plant lighting

The uniformity of LED plant lighting will make cannabis buds grow better, so the uniformity of illumination will eventually increase the yield of indoor cannabis cultivation. So how to enhance the uniformity of the LED plant light, see below:

LED plant light chip distribution: After the light bead ratio is obtained according to the characteristics of the LED plant light supplement light cannabis plant, how to intersect between the chips is calculated, and finally distributed on the plant light package and COB panel according to a certain rule. Make each LED cannabis plant light illuminate the main area of the light quality and light intensity uniformly.

LED plant light installation height and distance distribution: the arrangement of the spacing between each LED plant light is mainly determined by the light intensity, in addition, the installation height of the LED cannabis plant light must be considered. After a comprehensive calculation, the distance between each LED plant light Distance distribution to ensure the uniformity of sunlight in large-area cannabis cultivation.

Physical reaction with optical equipment: LED plant lights can also achieve efficient use of light under the condition of uniform illumination. The main physical principles used are light reflection and light refraction.

The LED hemp plant light uses the reflection and refraction of light not only to make the light more uniform, but also to achieve high luminous efficiency. It mainly uses the reflector and the metal substrate used by the COB. The principle of the LED plant light reflector reflects the light emitted by the light source into a beam, increasing Local light intensity, the reflective effect of the metal substrate is also to maximize the light energy emitted by the LED plant lamp lamp beads to be used by plants, the reflected part is auxiliary light, it also has the role of fixing the lamp beads and heat dissipation.

The principle of light refraction of LED plant lights is mainly to use optical lenses, the principle of which changes the propagation trajectory of light, generally single lens and retest lens are used, which can control the light distribution very accurately.

LED plant lights regulate photoperiod and spectrum

If cannabis is grown outdoors, it is not affected by people, but if it is artificially grown indoors with LED plant lights, we can control the photoperiod of cannabis by adjusting the spectrum of LED plant lights. In order to obtain the best yield, density and bud size, the correct LED plant light spectrum should be used during the flowering period of cannabis. Different wavelengths of red light at the flowering stage of cannabis have an impact on the formation and yield of cannabis buds. Plants under the red light of LED plant lights The body contains high chlorophyll content, strong photosynthesis, high carbohydrate synthesis, which provides sufficient material and energy for plant growth; therefore, red light promotes the formation of plant chlorophyll, promotes stem nitrogen metabolism, and greatly promotes flowering and fruiting. effect.

LED plant light to control temperature

A good growing environment is essential to the health of the plant and its ultimate effectiveness and yield. When the temperature is too high or too low for your plants, no matter what you do, your plants will not grow normally and the buds will not become fertile.

Too high a temperature in the later stage of flowering will also burn off cannabinoids and terpenes, thereby reducing the odor of flower buds. By controlling the temperature and humidity, you can actually increase the smell and potency of the buds at harvest.

The light source of the LED plant light is a cold light source. The province does not generate too much heat when the LED plant light works, and it can play a role in temperature control in the indoor planting space at critical moments.

The last is the harvest time of cannabis. In the last two weeks before the peak of maturity, cannabis buds will significantly increase weight. It will come soon. When most of the white hairs on the buds turn black and curl, the cannabis buds are ready to be harvested. For experienced growers, it is not uncommon to check the glittering trichomes under a magnifying glass to ensure the timing of the harvest.

Adjust the light intensity, uniformity of light and control temperature through LED plant lights to provide the best supplement light for cannabis cultivation, so that the final production of cannabis can increase, but also pay attention to the harvest time. As more and more countries legalize cannabis, let LED The market for plant lights is broader and the prospects are promising.
