Well, I haven't had even a drop of water run out the bottom. So....I don't know. I don't water much--maybe a 1/2 gallon each plant twice a week now. They don't even seem to use all of that. Mostly just using the water a a vehicle for their fertilizers. I've read that AK-47 doesn't take much water. I'll be interested to see the difference when I get a chance to grow some other strains.

Oh also, I drilled some more holes around the bottom of the buckets. They look like swiss cheese, but I know they aren't sitting in a swamp at least.

P.S. Thanks for the rep and compliments. I'm having a blast!
