you use green light during the dark periods in the grow room to not mess with the photoperioid, blue light is mostly for vegetive growing and red/orange light is for flowering

ya plants dont take in green light at all, becasue they are green. 6500 K (blue) good for vegging. And 2700 K (red) for flowering

thanks bro's. make sense, so would you recomend the blue for Veg. OVER a normal sunbeam CFL??

It depends on how powerful the bulbs are. I use a 125w blue for propagating, a 2x250w blue for rooting (fresh out of propagator) and a 400w sunmaster for vegging. The sunmaster has both spectrums so most of the red spectrum is wasted but it covers a bigger surface area so is better when your plants are in bigger pots. There are a few companies making l.e.d grow lights now though, they come in red, blue or mixed spectrums, have the benefit of cfl,s (low power consumption/ heat output) but can be used all the way through both cycles.
