I dont want to start a whole ruckus over this but it has to be said. If you so a full grow with cfls you'll never get the tight, thick nugs you would with an hid. If you're strapped for cash, check out
The $20 150w hps Its not the intensity ofa big kilowatt lamp, but its a frig of alot brighter than any comparable cfl and a great starter lamp. If you want airy, wispy buds, by all means get some cfls. But if you wanna grow some
fat nugs, Gotta get that HID!!!
Just my humble opinion.
Good luck with whatever choice you make, but think about it, watch
Greenhouse Seeds on Youtube those guys win the cannabis cup pretty much every year, and tell me if you think they could do that or even come close with cfls.
The pros do it, every "comercial" grower does it, and most importantly I do it, so it must be the right way to go!!!!
Good luck and happy growing!
