Do you have any tips for keeping a self contained terrarium? I’m making one for school but I’m worried the plants won’t grow fast enough to sustain oxygen for the creatures inside. So far I have ~3 pillbugs, two small slugs, one rose sawfly larvae, a juvenile millipede, an earthworm, and some sort of tiny red mite(?). I put some chia seeds in there because they seem to grow very fast, and could maybe help with oxygen? I’m unsure what to do
I’m afraid I’ve never made a self-contained terrarium, but perhaps some of my followers have and can comment or reblog with any advice they may have. :)
