Yeah you could do and it wouldn't alter the quality of the bud you get, but a metal halide will keep the plants shorter than a hps for veg. The plants will stretch a bit in comparison to vegin under a halide or blue light spectrum bulb.

You can but need the ballast that will do both. I have one that has the cooling tube on it, with a fan built in.
I also top sativas to keep em bushy and get lots of smaller colas. My height is limited in the cabinet so knda have to top them. :mrgreen: :peace:

See: Conversion Bulbs, these are bulbs modified to be usable in your ballast. If you want your HPS ballast to power a Metal Halide bulb, you'll need the Metal Halide conversion bulb. See any online bulb suppliers or search google for a local shop ie. "hydroponics near city, st"

st = state. obviously. just, put the two letters for ur state
