Hey guys, new to the forum and to growing in general. I made a grow cabinet and everything in it is perfect.... Except for the Ballast(I think). I bought it refurbished and the grow store claimed it had been extensively checked and qc'd. I brought it home, plugged it in... and nothing. No sound, not a peep out of it, and of course my lights don't turn on. Am I retarded and don't know how to use it(since it came with no manual), or does this sound like faulty equipment that should be brought back?
