To everyone in doubt what good CFL's and reflective material can do, I will tell you that CFL's do exactly the same as a METAL HALIDE and HPS. Stop being misguided. FLO's can produce good product at a fraction of the cost on electricity that HID's do. Lets get real here folks. LUMENS are LUMENS, A Kelvin rating is a Kelvin rating, and if a CFL is closely proximated to a plant it will not lose the lumens as drastic as you might think. Get a light gauge and check it out yourself. HPS has to be held father away due to heat and with that you lose nearly half of the rated lumens that bulb states it produces. On the other hand you can nearly touch leaves with CFL's with no problems and you lose virtually NO LUMENS.
This person did nothing but use CFL's/FLO's on their grow and I can vouch because I did the little Bonsai rope trick on 1 of my plants and she if a fricken monster!, So is her sister who has no bends. I am 2 weeks flowing and my buds are getting as big as when I have the SUN to produce.
A little more research about light and lighting and you might find yourself saving on your electric bill soon enough.
I am defending CFL's folks so don't get pissed off, just do some research.
