Hello GC, like the title says I need help making a drainage system. I grow in a 2'x3' closet and have about 4 plants running at a time. I grow in soil but I do not have a drainage setup (so I use pots without holes in the bottom) and thought it was time I set one up. I have been looking around online for the best setup but cant really find anything thst suits my needs. Anyone have some suggestions? Thanks.
