Autos do better indoor than they do outdoor, light timing is not as critical as with photos. IF/When you have problems with an auto it affects yields directly, where a photo can be recovered, cloned, reveged.
But one can go 12/12s with the photo at 3-5 weeks old and have a shorter faster crop, as fast as many autos.
When looking at seed look for the size the plant is supposed to get. Some are intended to be only 12" tall (60 days) at harvest while others can get 6' tall (120+ days), the shorter is faster to the finish line usually.
