You mean like use the metalk halide and hps for the flowering plants? As of now I have 2 seperate rooms. Flower room, and veg room. Each has a 400watt flower got HPS, veg room gots M.H. And seedlings under CFL's, as well I have soem CFLs hitting the undergrowth on the flowering plants. I also built a 8 bulb shroud for CFL's which I am using on the side of the Flowering plants to hit the lower budsites. I have been changing things around constantly though. I had a seperate section on the top of the closet in the flower room that I was using as a veg area, but even after sealing the shit out of it I was worried about light leak. I am thinking of setting that back up and having 2 fdlower rooms cause I am running out of room to flower plants. I have 5 plants ready to switch to flower but nowhere to put them
