I used to do a lot of seed treatments and watch the roots in a box with glass walls and about 18 inches deep of soil and maybe 2.5 inches wide. It was great for learning. Anyway I can’t find them and want to buy more. Does anyone know where I can find them? I’m struggling to find on the internet. Thanks
