I have 1 free auto northern light im wondering if i can keep it in the room with my Photoperiod for their 18/6 and then switch to 12/12 when they do or should i keep the one auto at 12 12 the whole time. im growing the photoperiods big (already started them on halloween 2013) so there will be like one to one and a half months from seed under 18/6 for the auto then what ever left under the 12/12 when i switch to flower. WIll the switch effect the auto? If so What is the best way to go about this?
