12/12???

My setup is a closet which I divided into half veg and half for flowering. After about 45 days I moved them to flowering. At that point they pretty much burst with joy with new growth spawning everywhere. The problem is I still have 4 in the veg side cause I have no room for them on the flower side. I want to know if I can just 12/12 the whole thing from start on my next grow for more space?

don't see why not.

I have done some reading, and a lot say they do that right from the start. Looking for opinions or someone who does this
