First Grow Ever! 12/12 flowering,

ok im going to head to the super store and look at some lights decide what ones to buy, OK ive done some research and heard some opinions. im thinking maybe 7-8 compact fluorescent lights some y splitter's and some sort of reflective backing for it.

Then add up all those bulbs wattage, and find out you have the same amount of wattage as a 400 Watt MH or HPS combined up. I'm just saying

You could get about an eighth from that plant.

ok so i saw this 500w MH lamp the otherday? would that be better than CFL's?
