There are ton's of reasons to go with auto-strains. And if grown to maturity they will be just as potent a photo-period strains.
Autos are much less forgiving. And as soon as the seeds pop the race is on. Anything that happens to delay or stunt the growth will likely result in lower quality flower.
Seeds really aren't that expensive and you can try out more strains by a new line each new crop.
Oh also since you brought your girls in from the outside. You gotta make sure to clean up the tent and grow space with strong cleaner (e.g. bleach) after the crop is harvested. I don't know if mites and other bugs are common in your area, but those things can be ruthless and nearly impossible to kill them off, if they find their way into an indoor grow room.
No I didn't bring them from outside, I switched from outdoor growing! It's a proper indoor run!
Sorry about that, I misunderstood your last reply.
