I wasn't aware of that. I thought since this was just a small space I could just go strait two the needed pot which was two Gal. So now do I need to go back and put the ones I allready have under Veg light's into smaller pot's? they look good and healthy the way they are now, I hate to disturb them if I really dont have to. But if the way we have done this wont work out, let us know now PLEASE. this is supposed to be a 4 to 5 week veg period and 8 week flower give or take the process was around 12 to 13 week's. the plan's I went off of the guy stated he used the same tub, pot's, and light's for veg and flower. we adjusted our's a bit, and compensated the light's and vent's for the bigger tub. We think it will be fine. let us know.:thumbsup:
