hey guys......I live in Cape Cod Mass... I have a couple thorobred plants(kush and white russian) that I started in June and I was wondering what was the maximum pot size I can grow them in.... I was thinking trying to plant them in 15-20 gallon containers for max yield. I grew one tree last year and it reaped after hallowee(indian summer)n, and yielded about three ounces(1 per gallon of soil). If I plant my babies in large pot would they be able to yield plenty, or is it not enough time for them to reach a good size or even survive the frost? I already planted 2 in 17 gallon pots.
