If you only planned on growing one plant or just a few plants and then clone a mother my setup with the CFL's or some cheaper tubes is great but you could just run a small 400 HPS light with a 400 MH conversion bulb. That way you spend the money on one light but just an extra 100 on the bulb isnt too bad, and i can tell you a 400 watt MH will beat the shit out of my 16 42watt CFL's.:thumbsup:
