3 kinds of lights will work. Florous, Metal Halide, and High Pressure Sodium.
Any one will se a whole grow through.
It is all in your budget. I personally do florous for veg. and HPS for flower. If I had the space for my veg. it would be a Metal Halide for veg.
If you want only one setup get an HPS that will get you through a whole grow fine.
My "Dream setup" would be MH for veg. and HPS and MH for flower. in a dual bulb reflector with digital ballasts. but then thats a dream. hahahaha
