Ive heard of people getting good results with CFLs.. Especially if you have over 600 watts..I'm using a 200 Watt CFL along with 4 other small cfls giving us a little over 300 watts..i'm sure our plants would be bigger if we had more light but if thats what you have to work with, so be it...They're growing so they must not mind flourescent bulbs that bad..

Good Luck!!!

And not that i'm anyone to be dishing out advice but if i can help with one thing it would be, not to worry about the end result too much..Get it going first and make sure your plants are healthy, yield isn't even in my mind yet..

If i get an ounce of smokable buds from 2 plants, i would consider it a success (considering its my first grow and i didn't even know the definition of germinate 2 months ago) :S5:

Again good luck and post pics please..
