I have the tent in question. I have about 10-12 plants (not exactly sure) ranging from 2 gallon pots to 3 gallon. I would say try to fit as many 2 gallon pots in as you could, it all depends how much you want to veg. You could fit 9 plants in 3 gallon pots quite well, it would be crouded, but good, or 12 in 2 gallon pots, or 1-2 huge bushed in 7 gallon pots.... all depends how much veg you wanna do
