I was so used to using HPS that the metal halide seemed weak to me. but I was using a 400 watt CONVERSION bulb, wich I found out really only gives about 250 watts of power on the metal halide. Well that was great for gettiong the plants started, now I'm back on the 400watt hortilux HPS bulb & I even added another 400 watt set up!
