From what I understand is that if you put more than one plant in a pot there roots are going to fight each other for space, one always wins and the Other one will suffer. Definetly not recommended.
I currently have 12 2gallon pots in a 4x4 and I could probably switch to 3 gallons but it would be packed at the bottom. I'm thinking about switching to 9 3gallon pots and I could do that with ease.. it would be more room and more canopy space per plant than I have now. I use to do 4 3gallon pots but that didn't cover my needs for meds..
