Hello guys,

I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me:

Our options are as follow:
940nm, 850nm, 660nm, 630nm, 610nm, 590nm
570nm, 530nm, 510nm, 470nm, 460nm, 400nm
and a total of 64 LEDs in the bulb.



I've got in my grow notebook the following quote from a post:::
<<<<<<<<<<<<<
for good growing you need blue, red and deep red spectrum. for clorophile A you need 400-430nm of blue and 650-670 nm of red. for clorophile B you need 420-470 nm of blue and 620-650 nm of red.
peak absorbtions are at A: 425 and 660 nm, and at B: 450 and 630.
the power of spectrum should be stronger in red spectrum (arround 85-90%), others arround 5% of each. i did some test grows, but i only used 470 and 630 spectrum and the plants looked just fine. if you give them all the spectrum (for A and B type), they will grow even better.

What do you guys think? I think this is great oportunity, they're offering to build a couple of prototypes so we can test them out. At the very least, we're all going to win from this.

There are two threads I'm following on the boards of Overgrow.com about LED lights, but it's just a mess in those boards. I preffer to discuss this here with you guys.

As to the power, the anlges of the LEDs, the soldering, voltage, amperages, etc. I'm pretty sure we'll hammer that out with the company engineers.

What I'm looking in this thread is some solid advice on what would be our best trial run... what LEDs to use?

I don't know what you think, but initially, I'm thinking we should try two types of bulbs: One for vegetative growth (blue). The other for flowering (red).
Suggestions?

Thanks,
