i grow indoors in az but have thought about outdoors - problem is the plant will start flowering in mid to late september and you're just not going to get any time under 100 f for veg. i guess you could plant in september and treat it like an inside 12/12 from seed grow but you're not going to have a very big plant.
Come up to flagstaff man its plenty cold up here. Plus the weed is shit. Plus the college is shit. Plus... wait a second I cant go over this whole list, I HATE AZ STATE!
