I would personally use one of those extra hids in the flower room. But you definitely look like know what you are doing
Not really, but I am a quick learner. It has been a bit of a hap-hazard process and I can see that now, thank you. I am pretty sure it is going to get some more adjustments and/or new fixtures later. I was considering a couple of CFL type fixtures on the sides/corners of the flower room for more wattage and full spectrum.
I was afraid of going with a 600w in the flower room because the washer uses the same circuit, but we ran laundry today and no problems. I am thinking now it will probably be best to shift the 6" hood in the flower room to the side a little with the addition of some new hooks, and move the 150w unit in to the flower room so I have 550w of HPS in flower and 400w of MH in Veg. I have enough height in the veg room, once I clean up my exhaust lines, that I can raise my light up and get enough coverage for vegging with the one fixture I think.
I could also just remove the 150w and upgrade the flower room with a 600w HPS ballast and new lamp (If I want to spend another $250+). I am sure there are times when I am going to need to start flowering with an HPS in the shorter room if my flower room is still full, so the 400w HPS lamp wont go to waste.
