I would search for this topic, but 'mh' is not a valid search input, and most people never spell out 'metal halide'

so anyways, I work for a maintenance company and have access to a few MH ballasts/bulbs that are going to get tossed. Its going to be my first indoor grow, so I dont want to throw a bunch of money into it yet. So, if my only two options at the time are CFLs and MHs, what should I use?
