Pay attention when you purchase the seed as to just how big the girls will get. Not all autos are created equal, while some only get 18" tall another will get 48" tall (some can get taller, my WTBs get 60+" tall for females while the male is over 6 feet), so get what fits in you grow. Next is how long it takes to finish, I have grown autos that finished in just over 60 days (56 days claimed) and others that take 130+ days (120 days claimed) (of course they were the larger girls)
Also one can run photo period plants with less cost for power, less cost for heat control, just flip to 12/12s at 3-5 weeks old (or if you have room let them get a bit larger, dont forget the stretch) you will need to control them by topping/training etc..
Inside you do need to remove leaf for both air flow and light penetration.
Happy growing!
