I'll start off by saying it appears to me as if the 3500K warm white is there mainly for illumination/visual purposes, yes? That's fine - most of those are a bright blue LED with phosphor, no biggie, they still emit quite a bit of well-usable light.

600nm I would remove entirely. My testing data showed that the best response for red was from 630-670nm, lower isn't worth wasting the energy on, plus you get closer to yellow emissions which act as growth inhibitors.

The rest is perfect. I'm surprised I could see focusing cups, guess I've been making this stuff for so long that even blurry pics give me enough detail!

I figured you'd need the 3W diodes simply because of the fixed distance. Keep your eye open for my grow located http://boards.cannabis.com/hydroponi...icro-grow.html I'm using 1W diodes in a much smaller environment, and I hope to push a fat yield from such a small area.

Keep growin!
I need to restate one of the things I said - if you're doing AQUARIUM lighting - some light between 550-610 is helpful. This is where "full spectrum" lighting would likely excel, as marine plants have some chlorophyll sub-structures that work with those wavelengths of light. My fault for misstating something like that.
