You need to have a solid understanding of growing and how to keep a plant happy all the time. The better you treat it, the faster it'll grow. Duno why everyone has such a hard time with them.... most things to you hear about autos isn't true. I run an auto or 2 in my mom tent, or in vegging areas. Gives me a some fresh weed before the other grows come down. Sometimes I just experiment with them like making live hash or rosin, live bho etc. I don't think I'd grow a whole tent or room of autos but that's just me.
