no you can not run a hps bulb in a mh ballast, you can run a mh bulb in a hps ballast.and you can run a lowwer wtt bulb in a higher wtt ballast mh or hps. example you can run a 400wtt bulb in a 100wtt ballast. youcan even run two 400wtt bulbs in a 1000wtt ballast. go to my youtube search for growingmeds i have videos to prove it works.no bulb or ballast failure.:mrgreen:

I have the 175W grow light system from http://www.bghydro.com/BGH/customkititems.asp?kc=HLCSMH017BGH&eq=

I am getting ready to switch to flowering and am going to purchase a HPS bulb and I was wondering if it was ok to just pop it into my light/ballast? Is this possible?

Only way to get your Metal Halide ballast setup to light a HPS bulb is to get a HPS conversion bulb specifically designed to use in a MH ballast.
If you try to just throw a reg HPS bulb in there it won't light. the only ballast that will light both MH and HPS are switchable ballasts or digital ballast
