Just an update on my seedlings...they're alive and well under the LEDs, but not having grown too much I can't say how they're doing in comparison to HID lighting. They've stretched a bit till now they're pretty much touching the lights, but there's not enough heat put off by them to harm the plants it seems.

Soon I'm gonna hook up a wattmeter to my power supply and see how much power I'm actually drawing, but ideally it should just be about 3.2(Volts per LED)X.02(amps)X50(#of LEDs) = 3.2 watts!

Since its a ghetto rigged power supply, some is being wasted though a dummy load to trick the computer power supply into thinking there's a motherboard there.....so we'll see how wasteful these suckers are....
