I need to buy a 70w metal halide ballast for an inside grow i'd like to start. I can't even find one right now but if I do and would it be bad to use a high pressure sodium lightbulb during the flowering stages on a metal halide ballast? I'm not sure if they're set up the same, just wondering to save some money.
