good topic but before everyone takes off is a million directions maybe we should determin If some of the research that has been done is valid in its statements and results from grows done w LEDs looked at.

ive been tracking the LED thing for 3 years now and in MHO LEDs work very well for vegging if used properly - the thing is that the 2 most serious attempts PROCYON and HGLs UFO are almost cost prohibitive and offer no ability to vary the required light spectrum for BOTH vegging and flowering.

this site GreenPineLane has a dynamite response from industry (LED) engineers and not only is taking a serious look at LEDs but provides instruction and evaluation of other more advanced hydro techs....

stop in and look at the site lotsa pics graphs and valuable stuff.

to me LEDS look good for at least vegging BUT these guys CAN jump to the next phase (LEDS for both veg and flower) ......maybe - if they had some hobbyist intrest?
