I heard that you can use red and blue LED lights to add the red and blue spectrums to your plants without adding the extra heat of other lights. Is there any truth to this? I havent had time to research it, but its intriguing and I want to know. Anyone know?

Ponderings of late:

*Why do people die? To make life important.
*Is there a purpose to life? No, life is protoplasm with a reproductive nature.
*Do I belive in a personal "God"? No, the truth is one, but is shown in many faces.
*-isms are very dangerous things.
*We are the vehicle of spirit, we radiate "God" from ourselves to others.
*Eternity is now, experience it now.

I actually just saw an add for that type of thing in a high times magazine so yes it does exhist.. performance wise though, I havent the slightest idea.

High Times makes money for themselves... not others. So........ get it?

thought i saw graf back the other day, Still haven't figured out what he meant?? VV

I did some field research on LED lights. There are LEDS of ANY light spectrum/temperature you can think of. They consume VERY little energy. They do not generate heat. BUT.... they have VERY LOW luminosity. I saw huge LED systems, they can iluminate a big room for the human eye, BUT they send like 400 lumens. And as far as we are concerned, plants like lumens, thay need energy not just human visible light.
So, after this field research, I think the LED systems of today are not a good idea.

Oh, it is important to note that I researched common LED systems and not those sold for plant growing purposes. I couldn't find them here in Fantasy Island!

My 1 wk old seedlings are doing well with 2 blue and 1 red LEDs. However this only illuminates 1 plant.

Green LED'S?

I read somewhere that plants do not use enough of the green color spectrum for it to be useful. Red, Blue, Orange are the most important.



With L.E.Ds its not about lumens its about spectrum wavelength.


I have got good results from mine. Although i did a L.E.D./CFL combo, heard that was the way to go. No fluctuation in the electric bill, no worries about temps, very nice for stealth ops.

LEDs work but their terrible compared to other lights, cost way too much and you'll never get a harvest big enough to pay the lights off.
