Autos can be very potent, and they grow perfectly without having to worry about light leaks.
If photos weren't such a pain in the ass about their dark periods, they'd be nice to grow, since you can clone them. But, they are a pain in the ass, and therefore I avoid them. Especially indoors. Outdoors photos make sense because they run their cycle naturally. You don't have to protect them from light every night. Indoors, it's so much nicer to just plant a seed and know that in 3 months you'll have bud, with no tedious light control.
