my understanding of autos is that u don't have to change to 12/12 to make it flower, it will flower based on it's age. i also understand that u can grow and flower an auto under any light schedule from start to finish and it will happily do it's thing. i've read that u can go 12/12 if needed (i.e. if heat is a problem) but that 18/6, 20/4 or even 24/0 throughout is optimum (different people say different things). i've just started an auto grow and will be going 18/6 from start to finish.
