Floros are cheapest to buy usually. hps is best all around and will be cheaper/lumem..mh is best for veg...i personally think that hps is best all around...but then again, I dont know what im talking about either. hope that makes sense, i just got home from the bar!
HID (HPS or MH) is cheaper to run for the amount of light you get. Florous are less $$ upfront cost, but cost more to run for the amount of light. (I think it was skunk or GanjaGuru that said perfectly in another post). "Lumens per watt HID is less expensive".
