Yeah, you better go with the CFLs. The LED isn't doing the trick, and the green in it is useless because it's all refected off the plant and not used at all. They should be replaced with white if it was me, although some might recommend red(which I've read induces stretching). I think we'll all agreen that green was the wrong choice, though. Yeah, go with CFLs until dad get's his LED design perfected. Tell him to double or triple the LEDs and eliminate the green ones because they won't do anything for the plant, except make it appear green when you look at it, as the light is reflected back to your eyes.
Also, go with at least 50 watts CFL, higher if you don't have any reflector with them. I'd go higher anyway if it were me, but that's because I'm a light addict.LOL. I'm running 1,800 watts in a 5' X 5' space.
