sweet! I think I got my answer there. I have a 4x3 foot space but I also have a small dehumidifier in there so I could probably get 5 with one on top of the dehumid.... I am going to try it out thanks cuz I am bringing in off two about 6 oz... I need to bring that yield up... thanks a bunc.... how tall were you plants when done? and were they squished together pretty good?
