I just picked up 5 gallon fabric bags (smart pots?), and a bag of coco loco soil. I am ready to start over.
Those are big pots. 2 gallon, maybe 3 would be better IMO. Autos don't need big pots. All that will do is slow down the cycle so it takes longer to get to harvest where the trichs are cloudy and amber. Smaller pots of coco can see you done in 70 days. Big pots.... could take 90 days. Just as a general rule of thumb. There are other factors involved for how long it takes.
