We all know HIDs work but their power bill is enormous. This is why LEDS appeal to me as well as the customized rays. If you've studied biology you know photons are actually what are harnessed from the light (in our case LEDS) to create electrons within the chlorophylls of the plant. These...

How much faster is the growth rate/yield? What all do you need to produce it if one purchases a generator, what other products are necessary? How do you measure the ppm of your air? And lastly should it only be done in a closed sealed room? Does one run an exhaust fan, carbon filter...
