I'm betting the LED's wont produce enough lumens or a varied enough spectrum for the plants to grow. Remember the sun is the best source of light, and going into LED technology is moving very far from the perfect light source.

Noble Idea, but in everything I've learned about growing plants is the light intensity is very important as well as a nicely spread spectrum. It is known the Low Pressure Sodium is a very efficient intense light, but its narrow yellow spectrum makes it as efficient as growing with an incandescent.

I still hope it works, but I have my doubts.
Jiminy Reviewed by Jiminy on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.
