LED grow lights... input please.

To be fair, NASA is testing LED grow light technology.

The new digital ballasts are an improvement on magnetic ones though.

khronik Reviewed by khronik on 06-22-2007. 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.

Just an update on my seedlings...they're alive and well under the LEDs, but not having grown too much I can't say how they're doing in comparison to HID lighting. They've stretched a bit till now they're pretty much touching the lights, but there's not enough heat put off by them to harm the plants it seems.

Soon I'm gonna hook up a wattmeter to my power supply and see how much power I'm actually drawing, but ideally it should just be about 3.2(Volts per LED)X.02(amps)X50(#of LEDs) = 3.2 watts!

Since its a ghetto rigged power supply, some is being wasted though a dummy load to trick the computer power supply into thinking there's a motherboard there.....so we'll see how wasteful these suckers are....

The test is definitely in the results for sure.

I have been looking into the couple of leds available for growing and the only two that are even worth looking at are the Procyon 100 and the Smartlamps. The rest are all cheap shit.

Of the two the TI-Smartlamps are the best. They are the most powerful and they are the best at growth and flowering cause they have more than just red and blue leds. I was speaking to a commercial greenhouse guy who says they are the only ones that the commercial growers are using -- tomatos etc so it should be good for other stuff

There is a great little hobby site for growing with LEDs called Experiments with Hydroponics, Aeroponics, and LED Grow Lighting which is worth following for anyone interested.

They just started a tomato test with the Smartlamp which should be interesting to follow. Not sure how many stores sell these lamps yet, but you can always buy them online from the company at growrevolution.com

So, the seedlings should have grown now. What do the adults look like? Please?

I have seen LED's compared to HPS 400w, and they're almost identical.

this is strictly a LED grow I find online....

Thanks for the link. Very interesting, but I don't undestand why the guy has the LEDs 3 feet from the plants. One advantage of LEDs is that you can put them right next to the plants, for much better growth. He's producing scraggly looking plants, but he is experimenting, and he is getting buds. He needs more LEDs and he needs to have them closer to the plants.

Anyone herd or used these befor?

I don't know anything about that first one except that it looks terrible for weed farming. Is it even LED? Assuming the 2nd one is in the proper wavelength, then yes it will work well. You would probably need 20 or so to grow a plant, and 50 or 100 of those to come close to equalling the yield of 400 watt MH. Just a stab at it.

Its amazing how much credit NASA gets in so much credit for their "inventions". A majority of the time they have a need and other corporations create these technologies for them. Like mylar, created by the Dupont company(along with many others). Just ranting I guess. remember that anything in space was built by the lowest bidder:wtf:
