I was recently looking at these smart pots, about how they are supposed to be amazing http://www.smartpots.com/ they are designed for growing outside, but i was wondering it they would be worth using for an indoor grow (yes organic), IF so, what would be the smallest container i would be able to use through out the life term of the plant (i do not want to transplant into these pots, seedlings will be germinated then placed in them and stay there till chopped) I was thinking of getting about 20 of the 3 gallon pots to make the best of my room. What do you think? worth the money? best size? Really make a diff?
