Yup, I sure have man. I used nothing but CFL's when I first started grosing. I did..2 grows if my memory serves me right.

First grow I did, was an Afghan x Jack Herer, I grew it with CFL's, only 65W! Ha ha! Man, that's funny...anyways, I vegged and flowered under it, it took about 90-100days from seed to harvest, and I got only about 6grams of low quality herb. I overfed, a common mistake for newbies So that cut my yeild big time, and potency, taste.

Second grow I did, I used 85W of CFL's, I grew White Widow, it took about 80days from seed to harvest, and I got about 14g's from that grow. Mainly because they were very high quality seeds, I shouldn't have used them dammit!

Yes, it is very possible to grow with nothing but CFL's, with even greater success. If you want to do this, I suggest doubling the wattage used in vegging for flowering. If you don't, the buds will be light, wispy, and not of great quality. So if you used 100W for vegging, use around 200W for flowering.
