LED grow lights... input please.

[Blumen]

Prepare to have the light very close to your plants, unlike the pictures for those 5mm led-lights show. Closer than CFL.

Blumen Reviewed by Blumen on 12-24-2007. 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.

I still am waiting to see an LED grow that produced buds of any significance. I have no doubt that a person could get some decent bud from LED lighting. In general people are going about it wrong, and they refuse to spend any money to boot. At this point the initial set up would be expensive as hell to get one plant to bud nicely, but it can be done. Due to the life expectancy and low power draw, very soon they will become viable. Perhaps even today.

posted below are photos and a grow diary. i dont know if this is what your wanting but it appears to be the most extensive work ive seen thus far - he observes that on his next LED proj he would req of the manuf hes working w to increase the amt of RED lights used to foster more flower development

we can do better than this kids if we all share what were doing and how its working as for me im ordering my 1st ste of OFO's this week and starting my 1st LED grow under thier currend BLUE matrix and will f/u by req that a more RED matrix be developed


Experiments with Hydroponics, Aeroponics, and LED Grow Lighting

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.

Opie,
Check this guys grow...hes got them all over the place.....

Lowryder :wtf: (and, notice he combined a HPS with the LEDs) ... I'm with Opie on this one "show me a BIGASS marijuana plant grown under LEDs" :jointsmile: ... I don't think ya can show me that, without spending $100,000 on LED lights ... but, it is a very intriguing idea, regardless, I'm hoping for great results :smokin:

I think the point of using LED's (for me at least) wouldnt be efficiency of growing bigass plants, but instead, the almost zero heat generated.

Imagine a set of 6 large speakers (the 2.5ft tall , bigass ones)

In the bottom, you have walls lined with LED lights, on every side, and a lowryder/lowlife in the middle. no vents required, just a burping everyday.

in the top 6"? an actual working speaker

if you get 1oz / plant, and have 6 speakers, you'll be getting two thirds of an ounce a week, enough for a light/weekend smoker, and a reasonable amount for a medical user.

its the perfect stealth setup, nobody would ever realise.

Yeah, too bad he had to do like everyone else as done, and wreck the experiment by putting in other lights. The people that need to do this are the people that either don't smoke weed or have plenty of weed, so they don't worry about yield and ruin the experiment.

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.

[Opie Yutts]

I am not against LED lighting by any means, and I know that one day people all over the world will be trashing their other lights and switching to LED's. That day will be 6/12/0018.

Well dip me in shit and roll me in sugar.

Here's the best I've seen so far:

YouTube - LED vs. HPS 25 days into flowering

Or search youtube for "LED vs. HPS"

He did several videos at different stages, but this one is the last, and it's 25 days into flowering. Where is the results video?

Not sure. The video was posted in July...

But he has put a lot time and effort in his experiment...which I thought was well worth the look...He has spent some dollars as those lights are pricey...
