Can i use this (360W Plantmaxâ„¢ HPS Conversion Bulb - Hydroponic Grow Lights) On my 400W metal halide ballast?
Im waiting on ordering it until i can get a confirmation from someone . Any knowledge on this subject is greatly appreciated.
I know it's a novice question, but a buddy lent me his 400W MH set up. I don't want to fuck with it in any way. THANKS
