I have 3 gallon pots but I'm wondering whether I should move up to 5 gallon pots. I know the rule of thumb, 1 gallon per foot. I can get by with 3 foot plants although I would like to get to 4 feet. I can't go much bigger than that. Medium is soil. Style is ScrOG. I'm moving from being an outdoor farmer to indoor so even 4 feet seems small but I'll just grow a few more plants indoors to make up for it. I guess my question is, can I grow a decent 4 foot plant in a 3 gallon bucket or do I need to step up to 5 gallons? I already have my pots so my preference is to stay at 3 gallons if possible. Your experience appreciated.
