I was growing in 5 gallon pots. I wanna fit more plants into my room and I was thinkin' about tryin' 3 gallon pots, but I am worried about them gettin' root bound or something. I usually veg for a month or so then flower. Any input on that? Anyone else use 3 gallon???
As for your question I would think 2 gallon would be fine. It depends on your veg time, but if you flower quick you should be fine. I did grow a single expieremental plant in a gollon and a half pot. I put it in flower straight from the clone dome, no veg time. It took a little longer to start flowering but I got like 15 grams off the girl.
