Need some opinions on pot size...my father has been growing for over 30 years and grows in 1gal. milk jugs.. I personally think that's to small, and try to convince him to get larger pots, but he is very stubborn and set in his ways..he says that's all the dirt you need for a healthy plant..I agree...if you want plants to only be around 24" tall..but I'm pretty sure more dirt=larger plants, and yeilds. Right? We both do closet grows around 4'x4' under HPS, MH, and CFLs. Opinions please..
