Ok I have a wonder women plant, two cheeses and two grand daddy purps. I've had them under cfl lights for four weeks and was wondering when the best time to switch em to 12/12 from 18/6. Any help is appreciated.
That all depends on how big you want your plant to be man. If you have the space/lights you can veg it for a loooong time. Take it as big as you want it, and remember that during flowering she will be get a lot bigger too. How big is your flowering area? How much light do you have/will you have?
