First grow here, I've got four plants, allowed up to six legally. No idea how much I'll get in terms of total yield, maybe 6-8 oz, but I was thinking about my next crop and will probably stay with four plants. Maaaaaybe five, but probably not. I love being able to move them around, spin them to change light coverage day to day, and have room to LST without having to set up a net for training. I got some 24" bamboo stakes for the next run, so I can open up the canopy some more, still trying to avoid fixing them in place. IF I do another run early next year, it'll be photoperiods, and I'll probably run two plants max.
