I was thinking to "veg" an auto,till pistils show(feminized) ,than put in in my friend's tent who will be switching the lights 12\12 to flower his grow.He has better light ,more space and good vent ,the thing is he'll be on 12\12 until i catch up.I know that autos prefer 18\6 throughout ,20\4 ,even 24\0,never heard of 12\12/Has anybody done an auto 12\12 in flowering?thx
