They are specifically made for cultivation, but for cannabis id say only to use for vegging. They come in 2 kinds 2700K for flower and 6500K (or w.e it says on it) for veg. 13,000 lumens so for veg they sure get the job done + they have best PAR (Photosynthetically active radiation) number of photons/sec that hit the surface of the leaf (u could say?!) and u dont need any ballast, it's built-in in the lamp, xD. But for flower they still dont seem to get the job done as an HPS does...lol ur cflis a little more hi tech than mine as you can see from my earlier pic, im using spiral 40w cfls and a pie plate reflector lolbut it gets the job done. some people say you cant grow under 2700k for veg but thats all im using
