If your co-op has money to experiment, then I would say go ahead and get some of those UFO's. I've studied up on what's available today, and those are some of the best available at this time, if not the best. However, it would be experimental at this point, and I would quadruple the number of UFO's per area that they recommend. I would not deplete your entire lighting fund until you tried maybe one or two of those for an entire grow, budding as well. I keep saying that I have yet to see anything budded solely with LED's that produces anything worthwhile, and I have yet to be shown how I am wrong. They work OK for vegging, budding is a different can of worms.

Notice the info said it can be used as a supplement to CFL or HID. That's all I would recommend at this time, and your money would be much better spent on some CFLs that are the proper spectrum. If you want to steer away from HID because of heat/power draw, I would recommend studying up on the newer more efficient T-5 fluorescent lights. Of course there is nothing on the market that compares to the results you get with HPS during budding.

If you or your clients are willing to spend whatever it takes, and you are dead set on getting LEDs at this time, I would pay someone to make the proper LED arrays for you, or at least design them. People who manufacture LED lighting products at this time use maybe one nm (color) for blue and one for red. I'm guessing to be truly efficient, your going to want about 6 or 8 other colors, or varying degrees of red and blue, with the blue being the dominant color during veg and red being the dominant color during bud. Not just any blue and red, but the proper nm that corresponds to peak chlorophyll activity.

Good luck and let me know if you have more questions. I'm not an expert, but I have studied LED's.
Opie Yutts Reviewed by Opie Yutts on . LED grow lights... input please. 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.
