I wouldn't. Okay let me explain. First I'd start under something cheap to operate, that gives blue light. If you plan to flower under HPS600, you can veg under either flouros or a MH250. Read this thread:

Look very closely at all the pictures and note the relation between plant size and pot size, and that the distance between plants is constant. If you start under a big HPS you are WASTING MONEY.
First decide how big you want them to finish.
Then calculate how many will comfortably fit in your space of that size. Add a couple, because being squished together for just a couple weeks prior to harvest isn't all that bad if you have good air flow.
Next, start twice as many as you hope to finish. Remember males are useless.
Only use your HPS for flowering. Yeah, you CAN use it for veg, but it increases stretch. In fact, keeping your halide or blue flouros as the light source for the first 2 weeks of flower will help keep your canopy flat. Check out the bank of flouros showin int he closet indiscretions thread. It cost ~60USD for the 5 fixtures and bulbs, and gives good, and cool, coverage for vegging plants.

IMHO, those elites are beautiful, wonderful, sweet tasting strains that are worth growing out but trying to bank on wieght is kinda setting up for disappointment. On the up side, they get you WAY higher than lower quality genetics would.

Would you rather have a pound of Beasters (worth $2800USD) or a pound of OGK (worth 6 grand)? lol! I know the answer to that one.
