Do you happen to have à link for info on this?Leave it set at 600 with a 600 watt bulb.... Don't fuck with shit if you're not willing to read about it first.... lowering/raising the amount of current or voltage to the bulb changes the spectrum that is put out.... Also changes bulb and ballast life/longevity.... Go read up or don't fuck with the switch....
Lol will do. Do you have à grow journal?put that bitch on the super lumens setting and let er eat!!
