A_Aronanswered grow question 2 years ago I use 3 gallon and 5 gallon pots. I put 1 per square foot. The 3 gallon pots allow more airflow around the pots, which is good. I use bar style leds. So that would be 12 pots under each light. Depending on strain and training, 130g per plant is low side and 200+g per plant on the high side. I have gotten a half pound of each plant growing autos before. It is possible.
