Unless you can fit 9 3 gallon pots, I would go with 4 5 gallon. With six pots in a square tent, not sure it would make sense. However, I do think 3g smart pots would be fine for your tent. I've grown in both 3 and 5g smart pots and haven't seen any different in yield. That being said, I do typically go with 6 5g smart pots in my 3.5x6 space.i have a 3x3x6.5 tent and a 600w hps for flowering
what should i do 4 5gallon pots or like 6 3gallon pots
