To Physicsnole, I have read with great interest your posts in this thread as well as in the LED "theory" / build discussion. Great research and insight.

I have been looking into the LED area for some time. So far, I have rejected the generic array's of low power LED from China. I was encouraged by the LED UFO grow trial done by high times mag. Almost as good a result as the 400HPS, but not quite...

Now I have been following the grow by SNS using the procyon's. great progress.

I think the Procyon's are the best grow I have seen published so far for herb using LED.

However, I think you are definitely on the right track when you are looking into additional supplemental wavelengths. especially and including the 660nm.

So, a question. Are you planning on getting into the business of building LED grow lights? Or are you only doing the research for your own home built grow??

I would be very interested in lights like you describe with all the mix of lambda's.

Also, I have found one other LED light supplier out there that I wonder if you have checked out: Theoreme Innovation in Quebec canada. From what I can tell, their lamps have more light out than the Procyon's and are equivalent to a 600watt HPS (their claim.. but the claim is verified by Agriculture Canada with a grow of lettuce and tomatoes). From digging into them, it appears their fixture is a bit more powerful than the Procyon, AND it looks like they are using several wavelengths in their design. More than just the red and blue combo used. It also looks like they are using high power LED. I have NOT been able to determine if they are using 1watt devices, or 3 watt devices or which brand or brands. But it looks like they have more LED bulbs and a wider frequency coverage.

Have you checked them out? Anyone on this thread looked into them. NOTE: I am not a spammer and do not work for the company. I am only looking to find the best solution for my needs and am looking for any feedback comparing the procyon's to the ones from Theoreme Innovation.

Or, better yet, I could buy some lamps ready made from Physicsnole!
