led's

anyone know anything about using red, blue, green and even yellow led's for growing the good stuff? Nasa are using them at the moment with lettuces and the like with amazing results. I'm desperate to find out more about this.

I need more info' on this: How many led's for say 40 plants? Or, rather, what wattage for 40 plants?

Think of all the different colours of the spectrum you could introduce to the plants. Plants also benefit from green, white, orange light.

I know i'm trying to run before I can walk, but like you said, this is the future of growing. Maybe that's why it's easier for me to want to try something like this because I'm new to it all. It would be much harder for someone like yourself with your thoroughly tried and tested methods to want to try a different method.

We old growers want to try new stuff, too! When we first heard about LEDs, we started checking into it. I saw my first fixture 3 years ago. Like any new technology, the initial prices are too high, and the results aren't there yet. Two years ago, I decided that it would be several more years of invention for LEDs to be a viable option for consumers.

The prospect is definitely interesting. Using HID lighting, the biggest problems are heat and electricity. Using LEDs may solve both of those.

What I've read, the plants need only light in the red and blue range.

I'm only mentioning about the other colours because i was reading some info on the nasa scientists and their work with led's and lettuces. While just using the red and blue light they noticed some purple discolouration to the lettuces and found that introducing green light made the lettuce green and healthy again. They didn't say much about the white and orange light, only that they are also beneficial to plants.

I konw someone who is using combination, high efficiency hids.. around a primarily LED setup, the hids are placed in teh middle and cover the entier specrtum, but during each growing stage different led lights are used. This has worked well, and may server as a bridge for conventional growers as this has for my friend. Alot of experiementation is needed though.

they sell little blue and red led grids at my local grow shop, i don't know much about electricity but don't they take almost nothing to run? i just bought an led flashlight, only has 3 leds in it, but it's brighter than most mini mag lights ive owned, whiter light too, almost blue.

I think led's are the future.
They are just not cheap enough yet.
Give them a year or two and the newness wil wear off and they will be cheaper.

Midgrade', when you said 'too expensive', could you elaborate please. As in how much?

Often, I've found, price is a matter of perspective and speculation. sometimes you have to spend a little to save a lot.

try over a grand for a starter kit of of two red led's and one blue one. Just saw this thread after looking around for a while. type in "led plant" and google it; if you check out the results, you'll see that an led set to to the wavelengths plants absorb best to be insanely expensive. I assume every grower, however, would be envious of 75% power savings over 400 W HID/HPS, and a bulb life of over 7 years at 18 hours a day. It sounds like the perfect veg room light setup, but at an outrageous price. Does anyone know if the grow ops in amsterdam have started to test this stuff out? I was hoping to see some pics of some bud grown under this stuff...

I just noticed you are from Europe. When you said over a Grand, were you talking £'s?

nope, dollars. 2000 pounds would be even more ridiculous. It isn't true, however, that growers haven't been experimenting with led's on cannabis. The nasa research that started all of this as far as led implementation for agriculture was published in 2001. Check out cogi's led experiment at reeferworld.com. I just went through the entire 24 pages of posts, and while more than you can take in one sitting, learned a hell of a lot as far as what wavelengths to try out for my first led grow light. Someone has to experiment...

Over a grand where i'm from means having over 1,000. Not 2,000. That would be two grand. You stated over a grand... if that's dollars then it would be about £550. Which isn't a lot of money.

Now, if it is $2,000 that would be about £1100, and this would seem pricey. Yet, the leds last for seven years... save loads on electric, eradicate heat problems, improve taste in hydro by using different coulours of the spectrum.

So, is it over a grand in $'s, or over a grand in £'s?
