What did HIGH TIMES say about LED's???

[gladysvjubb]

Hi Folks,
I don't have access to High Times Mag. Could anyone who read the article on LED growing please give us a thumbs up or thumbs down . I'm sure there are 6 of us or more that would be interested in what the guru's say. Thank you........

fuck.. If LED growing is a good thumbs up.. THat will revolutionize growing for sure.. think about it... ZERO HEAT!! .. Only down fall of it that I would see is that you would need to get a heater inside your grow areas now instead of an A/C

BUT who knows.. though, I would imagine it being way way way less costly then HID lighting and CFL's.. BUT im sure manufacturers would jack up the prices..

I have that issue right here. This article on the UFO is basically an introduction on the theory of why the LED's can work. They don't take a real stance one way or the other.

"Ongoing trials have pitted the LED UFO against various sizes of MH and HPS bulbs. Preliminary results submitted by our testers, while not nearly conclusive, have laid support to argument both for and against LED growing."

"In these experiments , the UFO was tested in identical environments against 400-and 600-watt HID bulbs. Early indications of big energy saving showed across the board, and is very clear that heat production was minimal. As an added bonus, in the one trial that has finished and harvested, reports of higher resin production were submitted.
On the other hand, all experiments showed signs of stretching within the LED test groups. Increased stress is sometimes a cause of higher resin production, but it is not the method by which growers hope to achieve potent yields.

"LED lights are manufactured in a broad array of packages, with some providing a fuller spectrum of light and others focusing on a few specific colors. The LED UFO, for example, focuses on the redder and deep blue spectrums that are largely missing from current market HPS and MH bulbs. Hitting 455nm (nanometers) and 627 nm respectively, the UFO emits a combination of spectrum's, forming an almost violet hue over gardens."



"...plants in hydro set-ups under LED lights need fewer watering cycles per day than test subjects under normal HID lighting..."

"..in the first trial that finished, the grower reported a 12% increase in yield for the UFO-grown crop, which was side-by-side with a 400-watt MH lamp-grown crop. Not bad when you consider the UFO runs on only 90 watts."



and of course..


"The answers to these questions and more will be revealed in next month's issue, so stay tuned in and turned on!"

Excerpts -HIGH TIMES Issue -FEB 385/2008

Not sure if I'm allowed to just take straight excerpts out of a magazine like that but I here I have.

Thats basically the meat of the article for ya.

I get mine at 7-11 , I might be a paranoid stoner, but I don't really want to have my name on HT's mailing lists. So to the newsstand it is. Not to bad though, Slurpees abound.

Peace

Hi. Talking about led lights Arjan of the Greenhouse says that they are really good for veg right now but more development is needed before they are really good for the flowering ..........Peace

He's right!!

They seem good for vegging but lack power
and penitration into the plants for better flowers??
Too bad,i like the sound of less power!

I think one of the great possibilities of LED is that they don't need the penetration of HID, you can put them right next to the plant, plus having several points of light emission would allow you to cover the whole plant from all angles, not just from above.

At the rate LEDs are improving, they will surpass other types of lighting - when's the last time you heard about a new light bulb that was 2 times as efficient as what you have at home? With my LEDs, it's happened twice in the last year, and the big companies are just now getting on board in the last year.

the UFO uses LEDs that are at least 6 months old, and there are new ones out now that can put out almost twice the light with the same power usage. The newest LEDs are not available in mass products until 6 months or a year after they hit the small-scale market.

If you think about it, the UFO could potentially put out 150% or maybe 200% of the light it puts out now, if one were to swap out the LEDs in it, and you wouldn't have any increase in power draw. Since it, as is, can come close enough to the 400w HID to even be compared to it, then in a year, it'll far surpass it (as long as the company updates their design with the new LEDs, that is).

I remember when you could only compare LEDs to incandescents. Now you can compare them HID, which was always thought of as the most efficient bulb out there. - that alone says alot!

I'd love to build a 400w LED array, and then compare it. The issue with the High Times report is they compared a 90w LED setup to a 400w HID. put 4 UFOs in the grow room, save 10% of the power over the HID, and then tell me what happens - a much closer comparison.

Totally agree with that my friend

Bt i must say, LED technology is increasing fast, bt that doesn't mean it will continue to increase fast, there is only so much one can do before the maximum potential of a product, such as LED lighting, is reached.

I've heard from I.T experts that even tho home computers have advanced sooo fast, the "scientists" are now struggling to improve things like the Dual Core Processors any further because, for now at least, they've sort of maxed their technology and are trying to figure out how to improve further with out things over-heating etc. (the quad core processor type thing they're trying to build overheats and blows itself up within milli-seconds of being turned on; jst for an example ) so they're focusing now on making things smaller rather than running better/faster ... This could b the same for LED technology, and any other technology for that matter!!! Jst something to think bout

Good points for a stoner

Heat is an issue with high power LEDs, that's for sure. I've smoked tons myself.

One of the things that has improved LEDs a lot is purity of materials, and applying them with little to no contamination. That has a finite limit, without a doubt.

It's going to be an interesting next few years, that's for sure.

My computer says it dual-quad core and it's not blowing up lol.

 

[Guest]

Poodo, the dual quad core is a different processor to the qaud core ... the dual quad (from wat i've heard) is sposed to b like 2 dual cores put together (think of 2 bricks (small bricks lol) taped together in the middle to look like one) where as the quad is jst one processor with 4 cores (sorry i dnt no the tech terms and all that lol, i've jst heard from peoples in the industry) ... The dual quad was their way of getting almost the same power as a quad core with out the heating issue (a way round the problem, bt none the less jst as good as solving the problem entirely really) ... U can only slow advancement down, it would b very hard to put a complete stop on it!

Cheers.

one day led's will be best way to grow, imagine just having a cieling and walls full of blue and red spectrum leds, but where not even close yet, im going to say once they start replacing common bulbs like cfls and incandescents, is the time to switch, how long this will take i dont know, maybe a year or maybe 10, someone should do some research on this subject ( im to much of a lazy stoner)
