can I do organic with no drain?

I have an opportunity for another stealth cabinet grow but the design parameters dictate that a drain free pot would be FAR superior to a pot with a drain. I have always grown with a few drain holes in my buckets but with organic soil do I really need them? I am using the square kitty litter buckets for pots and I figured that I would put rinsed perlite and those aqua crystals for the bottom 2 inches then put a supersoil on top and a bit of a cooler soil in the middle/top for the seedlings to get a good start in. I'd start the seeds (Mako Haze) in a solo cup and transplant into the drainless pots. My thoughts are that I'd use a soil probe and water accordingly. Any excess water should be effectively held in my perlite/water reservoir, right? I would be careful and blah blah blah. Thoughts?

why cant you put holes in the litter box?

The pots would be a pain in the ass to get out or move unless the plants are short. The buckets are square and fit almost exactly into the space with very little room to spare. I don't have room for nor could I have access to a drain pan.

how many buckets do you have? take a bucket and cut in half and use the bottom as a drain pan, using a brick or something to separate them. but yes to your question you just have to watch the feeding but it can be done

2 buckets, 11.5x10x10 each, fitting into a cabinet that is 12 x 21 1/4 x 52 tall. The bottom 11 inches is solid, not a door, so the pots take up 11.5x20 of the 12 x 21 1/4 area. The bottom is not accessible due to some permanent shit in the way so I would have to totally pull a bucket out to get at the drain pan or bucket bottom or whatever. I wouldn't feed them anything but rain water and let my soil do the rest. Well, the Mako Haze is actually a longer flowering sativa so this run I might have to top dress a bit or something but regardless, rain water and light is all I have ever used.

Yeah you can do that. I rarely have runoff with my pots. (organic 15 gallon) The probe moisture meters may be handy for you...
