Hi,
I have been vegging my plants for 4½ weeks on 18/6 and now I want to switch them over to 12/12.
My lights currently come on at 9:00am and go off at 3:00am, so do I need to let the dark period go from 3:00am (lights off) to 15:00pm and then let the lights come on or should I let them come on at 9:00am (as normal) and go until 9:00pm?
Any help/advice would be much appreciated.
