Howdy
I'm new to this place, thought i'd share a little project I've finished/been working on (I'm an constant tinkerer).
I've played with growing small plants under LED lights for quite some time, starting with a few cress seeds in my early attempts with some success ,so decided to try out a larger system.
(Sorry for the crap photo's, my only decent camera uses film)

The current system resides in the back of my practice amp, it uses 3x 3w Red High power LED's and 1x 3W high power blue LED All attached to a mack-off great heatsink. The power supply was picked up for £2.50 from a local electronics shop and the current limiting circuitry is from this design:
Circuits for high power LED's
The current is limited to half an amp so they are not quite running at full power, but they chuck out a hell of a lot of light, and get quite hot.
Also to the left of the image is a fan blowing down into the top of the power supply to keep things a little cooler and some air circulating in the box.
Here is a photo of my little plant thats been vegging right up next to the blue LED for 5 days now:

Things seem to be going OK for now, hopefully they'll continue that way, although my little plant only has about 6 weeks before it's gonna have the chop due to moving house. When i get settled I'll be building a bigger system with more LED's.
Best part of the whole thing? the amp still works, so my little plant can rock out to some dirty blues.
