hehehe..

ive been researching LED grow lighting for the past few months, and all the information is so convoluted.
I have yet to see anything grown worth of dropping hard cash, on expensive toys.
skip LED.

checkout sungodlights

for LED's i would say unless its designed for growing weed! a typical LED light is no diffferent than any other current light on the market.
designed for growing weed:
Blackstar LED
Blackstar Chrome
California Lightworks
BUDmaster
Blackdog

lowend models barely covers a 2x2 for 400$ smackers, so a 2700k LED, is no different than a 2700k cfl

LED lighting is all about the spectrums of light that are not visable to the human eye. which the plants use. not just RED & BLUE
