My question is in regards to growing hempy style with perlite/vermiculite. If I have an area that is say 3x3x7 ft would four 2 gallon self watering pots be enough. Would I be limiting yield by not using larger buckets. I really like these pots because I want to put air stones in the bottom and they accommodate very well but I'm wondering if I should go to traditional 5 gallon buckets and drill the hole to make Hempys and just nix the air stones? Oh... This would be for autos btw.
