if i have a plant and it is growing nicely, can i move it into the flowering stage whenever i want by makin it a 12/12 fixture and will it stay the same height? or do i have to wait?
Well...one of the most helpful guides I found was the GrowFAQ over at Overgrow. That should give you a very good idea of what you need to do...but you could also veg it for 4 weeks like BoB said. It will not stay the same height once it gets its flowering growth spurt going, and some plants can even triple in size! GrowFAQ
