I have been doing a cfl grow for a while now and it seems to be working great. this is my first grow, im very excite! i have 8 26w cfl 6500k day light blue for veg and 8 energy saver red spec for flower. i then bought 4 extension cords at the dollar store, 4 light socket splitters, and some cheap sockets to use on the end of the extension cords. the whole set up cost about 120 total with fans and odds and ends. you can start cheaper, and then just buy the red spectrum lights when its time to flower.
