I'm in the same boat, dabumps. Given my short growroom height and my desire to let the plants fade at the end, I'm going with 7 gallon pots. I had been using crazy tall 7 gallon pails with SuperSoil, but run out of height quick, even with a SCROG.
I need the pots as short as I can, and I'm going 7 gallon Geo Tex and amended SuperSoil
