Blue-Only LED's for Seedlings?
- Thread starter AeroKing

It's not just about using "red" or "blue" - it's about using precise wavelengths (nm's, nanometers). Plus, Chlorophyll-A and Chlorophyll-B both have different absorbtion spikes for the wavelengths of "red" and "blue", so you will need at least four different wavelengths of LED's.
Then there are the other essential pigments which require thier own specific wavelengths of light - but I wont get into that! do you see where I'm going with this? The point is, you need to do a lot more research about growing with LED's.
The real bottom line is - you don't need any lights in a germination box!

OK, I guess it's a "seedling box", then. They're in there for maybe a couple weeks, then under a 400w MH.
The Blues are 225 Blue: 460nm (nanometer) wave length
or the combos are
60 Blue light LEDs: 465nm (nanometer) wave length
165 Red light LEDs: 650nm (nanometer) wave length
I'm considering either one of each or 2 blues.
Are you saying that these will be ineffective?
Or that I would need both spectrums?

To tell the truth, I have given up on LED's (at least untill somebody makes a real breakthrough). I was very impressed with things I heard about them a year or two ago. But the state-of-the-art hasn't really improved all that much in the mean time. I was "hot to trot" and bought several panals (in kit form) - but I was really disapointed with the results. So I'll just wait untill the "Rocket Scientists" get it right!
I would certainly recommend that you use the panals with both wavelegths. My problem is this - I'm scientifically oriented enough to be very taken with the "concept" of LED grow lights, but lack the "hands-on electronics experience" to experiment with them. If there are any "LED Guru's" out there - let's hear from you!!!! In the mean time I'll just sit and wait 'till someone perfects the bitch!
