Hey halfway,
I also have been researching
led lighting and have found several
Sites on leds the most informed site is (
Experiments with Hydroponics, aeroponics, and LED Grow Lighting ) Where they are testing leds in hydroponic applications it seems lke a very informative site.
I have also looked into diy led gfow
lights and have found several cheaper alternative solutions to cheaper led
grow lights. Hope that the link helps
