Two notes, though. First, be wary of the grow times; most seed growers report things like ready to harvest in 8 weeks. If you want good yields, it'll probably be closer to 10 weeks or so. Autos tend to start a little slow, then explode, then fatten up for the last month or so. Most experienced auto growers take 10-12 weeks on all but the fastest and heaviest strains.
Second, pay attention to the roots. Autos don't get as big because of the ruderalis genes in them, but their roots are meant to suck up nutrition from shallower soils (due to ruderalis living in areas with thin soils). Good, airy soils with perlite, aerated water, and air pots all help you get the most dank from your plant. To get fat, sticky buds from an auto you need healthy soil or a top-notch hydro setup.
