I'm pretty sure you need something higher in the spectrum for vegging. Usually for hid lighting you want MH for veg and HPS for flowering. You need more of the blues in the spectrum for veg which is what MH has, and more reds for flowering which is what HPS has. If you don't to spend the money, or your not going to veg for long you can get some 6500K cfl's.
