LED Grow Light Review: Hydro Grow LED vs ProSource WorldWide - 3X The Intensity!.mpg
3X The Light Intensity at 48" from the Light! That's what you get with http://www.hydrogrowled.com vs ANY other manufacturer! Notice how they're the only ones on You-Tube using a University Standard Li-Cor Quantum light meter, and giving you actual MICROMOLE readouts! No dubious Lux or Lumen readouts here! Only the light readings that ACTUALLY matter to your plants! Further proof that when it comes to LED Grow Light Technology, NO OTHER MANUFACTURER EVEN COMES CLOSE!
