ok so, i was lucky enough to have another 150w sun system bestowed upon me. Since the original is being used in my flower area, i have about a 4-5sq ft cab im using for veg, had CFLs in it, but i figured with the new ballast, perhaps i can use a MH bulb instead...So im wondering...

Can MH bulbs be used in HPS setup?

sorry out of interest what if you brought a kit that was dual spectrum then can you use both bulbs?

If you are talking about the SH dual spectrum they a big CFL's, very different.

You CAN buy a switchable ballast which will run both HPS and MH, they are very popular.

yes sir you can run hps for veg, i do. CHECK OUT SEEMORE BUDS movies, god dam i cant remember if its the first or second one but he pulls massive amounts of bud of a grow with only hps. And i was told that MH bulbs have a pulse start, and hps dont, or vise-versa. So using the non pulse start bulb in a pulse starting ballast will make that bulb burn out quicker. this info is coming from a light and ballast salesman at my work- electrical sales store.
