OK so for some people space is a problem, and for me at least, the normal 5 gal bucket wasnt going to cut it. I wanted to maximize on soil so i figured that i could make square containers. Becuase height was an issue i made the containers short but very wide and long. So if you want to make your own containers this is a very easy way to: Materials: Masonite (1/4"), 1/2" ply. and 90 degree angle ties Cut the LxW out on your plywood. Then cut the masonite, which will be used as your sides. I used a skill saw and it worked fine. Once everything is cut, drill the masonite into the plywood (see pic). Note: it works well if you cut 2 of the sides so they overlap the masonite from the other two sides, that way when you put on your corner holder it will hug tight. Then drill in that corner square thing, not sure what its called so that everything holds tight. Finally get a 3/8 drill bit and drill a few wholes about .5" up from the bottom on each side so that water can drain easily. Again this is a nice cheap way to get square containers for person needs. For bigger containers, i would put 2 corner squares per corner. Ok and i also have a question. Can i put the soil right in there or should i line it with something, dont know what though. I cant seem to find anything wrong with putting the soil straight in? Anyway, i hope this is helpful for some.
