my advice goes by the minimum of 50-70 watts per square foot. though in practice i am at about 125 watts per square foot! which goes a long way to explaining my heating problems.offtopic, email you got info on which wattage of lights and what it covers? im tryin to help this dude, but i cant find the info fast enough....i only remember 1k covering 8x8 or something like that
I even thought about using a 400w instead of a 600w HPS.
Does anyone know from experience that it is safe to use a lower wattage bulb in a differently rated ballast? I know it is not safe to use a 600w HPS in a 400w HPS ballast but is the reverse also true (using a 400w HPS in a 600w HPS ballast also unsafe)?
