I love this stuff....it's nice to get back into scientific experiments. About 10 years ago I used to design heart catheters for a big corporation. Since then I've been in finance.

The exercise my brain is getting from this is quite refreshing!

These guys say they can make these LED's to my exact specs. It takes the cost of my units up by $55 to get the exact wavelength LED, but to me that's well worth it if they work!

I was thinking of instead of ordering their off the shelf 120W light with just the 470's, I would substitute in 50% 430nm and 50% 452nm to comprise the blue in the flowering light. Sound like a good plan?
