Hi I will not be able to use a cfl, the thing is that I'm working at a company that buys crazy high power leds and I will be able to get one to use, because they are really expansive, LED light with 120 lumens per watt, its used where HID are used like street lamps and stuff... they have options of 4200k and 6000k and I will try to use one of this leds to grow and see if it works good.
I will stick with just 4200k then, it might take a little longer to veg but flowering will still be the way it should be
