I understand that but if they turn out not to be autos and I stick to 18/6 they will never flower. The question was if they are autos and I induce flowering with 12/12 can I then revert back to 18/6 or leave at 12/12.Hi dude what do u mean.if u want to veg and bloom under the same cycle.stick to the same light cycle.dont change back and forth .will shock ur plants and could hermie.happy growing every1
