"How to grow 100 pounds of potatoes in 4 square feet"
you don’t even need to put all that money and labor into building a wooden box.
use a large grow bag. if you have a sewing machine, or know someone who sews, just get some thick, durable, breathable fabric and make up a giant bag. roll over the edges, fill it with just a few inches of dirt, and plant your potatoes. then keep adding more and more soil, and unroll the edges each time, until your bag is full and the potatoes are finished growing.
this goes for other root type things, currently doing this with some ginger and sweet potatoes.
