how many cfl's?!?!

How many cfls at the least am I going to need to do this-_-

depends on the wattage. i find running four 105watt cfl's (around 400 relative watts each) works great for up to four plants. the lower the wattage, the hotter the bulb, though. so be careful with that. you're still going to need a pretty hefty ventilation system with any significant number of bulbs. but it all really depends on size of space, how many plants, and what kind of bud density you are hoping to achieve.

good luck and don't forget to floss
