ok my next question is lights for her. I have a multi use ballast. It can take metal halide, hps, and merc vapor. I have HPS and merc vap bulbs. how well would a norelco 175w HID merc vapor lamp roll in flowering? Should I just use the HPS? It is also a 175w HID. I know the HPS is rated at 16,000 lumens and a kelvin color of 2k. These bulbs were given to me and I dont have the slightest clue of what the Norelco Merc vapor lamp's specs are. I have looked everywhere online that I could think of. It is a weatherproof norelco h39-22kc/dx/s and is also has a 6d with an arrow pointing down. HELP?
