I was wondering if I could use a metal halide ballast for hps bulbs. I also would like to know a little more about earth juice products can these be used as a complete feeding system
As far as the lights go, some ballasts are "convertible" and can use either hps or mh, and some can only use what they are specified for. That's about all I know, hopefully someone more knowledgeable will chime in.
I know you can us MH conversion bulbs with a HPS ballast but I'm not sure about the other way around. Good question, and thanks for asking it...I wanna know now too.
