[Noisebridge-discuss] A visit to Noisebridge and info on Gardening with LEDs

[Roger S]

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.

Here's a really good place to start:
*http://en.wikipedia.org/wiki/Grow_light*

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.

This blog:

Says that you should concentrate on blue wavelengths, even though most grow
lights concentrate on the red end.

Overview article from Michigan State:

Hope you find this useful.  I'm putting together a page on our wiki to
describe my initial effort:

If anyone is interested, I'd be interested in collaborating on improvements!
