Had a fun and interesting visit to your space last Thursday, while visiting friends in the city.  Surprisingly like ours (i3 Detroit) and had a good discussion with Rob. I mentioned that I would provide some info about LED plant lighting, so here goes.<div>

<br></div><div>Here's a really good place to start:</div><div><font color="#0000ee" face="Times New Roman" size="3"><u><a href="http://en.wikipedia.org/wiki/Grow_light" target="_blank">http://en.wikipedia.org/wiki/Grow_light</a></u></font></div>

<div><br></div><div>Note that someone has actually patented a combination of wavelengths for growing plants.  Kind of a silly patent, since I think you could vary only slightly from it, and not violate it, with good results.</div>

<div><br></div><div>This blog:</div><div><a href="http://ledgrowlights.blogspot.com/2006/10/wavelengths-in-led-plant-grow-lights.html" target="_blank">http://ledgrowlights.blogspot.com/2006/10/wavelengths-in-led-plant-grow-lights.html</a></div>

<div>Says that you should concentrate on blue wavelengths, even though most grow lights concentrate on the red end.</div><div><br></div><div>Overview article from Michigan State:</div><div><a href="http://leds.hrt.msu.edu/assets/Uploads/LEDsInsideGreenhouses.pdf">http://leds.hrt.msu.edu/assets/Uploads/LEDsInsideGreenhouses.pdf</a></div>

<div><br></div><div>Hope you find this useful.  I'm putting together a page on our wiki to describe my initial effort:</div><div><a href="http://i3detroit.com/wi/index.php?title=LED_Grow_Lights">http://i3detroit.com/wi/index.php?title=LED_Grow_Lights</a></div>
<div><br></div><div>If anyone is interested, I'd be interested in collaborating on improvements!</div>
