The new dual spectrums....how in the world is ONE BULB going to give me PRIMARY BLUE or 6500K I want during veg...but then magically give me PRIMARY RED that the plants need in flower.

With both spectrums being present, if the red waves are not the stonger of the two, the plant simply doesnt get what it really needs.

How does the sun do it? Its rays dont change do they? maybe the bulbs are closer to what the sun puts off. there are a couple of people on here that grow from start to finish with only CFL's. I think Mand is one of them. please let me know what you think as i am willing to learn the ways of the samuri. lol
