Yes ive grown dwc with cfls..I grew this way for awhile. I still harvested to me what were great rewards. But until i started implementing cheapy hps lighting to my grow it was then that i realized what growing was all about..U can get a 150 watt hps lamp for like 20-25 bux online and even get a 50 watter at home depot for 22 bux and ad that to the cfls... U will respect hps in harvest and the smaller ones do not give off as much heat as the equivelant cfls per lumen output.. Try a small hps. Tripple bud growth and enjoy.
hope that helps.
