I think "totally wrong spectrum" is incorrect. Don't MH lights just emit less of the red/yellow light than HPS? They emit more blue light, and HPS emit more yellow, but they both emit a range of colours not just one spectrum. I am quite sure that is correct, but not 100% sure.

I do know for certain that you can flower with an MH and get great results, regardless of whether I got the details right.
