I had 8 CREE red's on mine, 4 on each side of a 2 x 10 inch mesh
did not grow a thing, 5 months long waiting, and waiting.
when I build the unit, I put the LED's right at the screen, about 1 inch off.
I have bin informed that this was way to close, 4 to 6 inches would have bin better,
my problem is, is that I build it all to be 1 inch, and thus removed it after 5 months, as I have to rebuild, so I can have more space between the mesh and led's
I don't know if there is a real wrong color, as some use regular bulbs, some T5 or CF,
I think it is a bit playing around, or gust check what LED's are used on manuf. units.
