Lighting LED only thread (the manual)

UCSanta Barbara creates the perfects the led's and UCSanta Clara rolls the 2.5 pound doobie. That schwarzenneger's done some good work in caly forn ya
 
just blue and red waves on the led jungle lights? looks like old tech....but yes, cool logo TaNg!:head:
 
helloe everyone! sotty if repeat but it 720 nm led so invisible to human eye that it seems to be off. my manufacturer assure me this is so.

Hay dude yes anything above 700nm is to broad a wavelength for humans to see so the LED will appear dark. http://en.wikipedia.org/wiki/Infrared




Name Wavelength Frequency (Hz) Photon Energy (eV)
Gamma ray less than 0.01 nm more than 10 EHz 124 keV – 300+ GeV
X-Ray 0.01 nm – 10 nm 30 EHz – 30 PHz 124 eV – 124 keV
Ultraviolet 10 nm – 380 nm 30 PHz – 790 THz 3.3 eV – 124 eV
Visible 380 nm–700 nm 790 THz – 430 THz 1.7 eV – 3.3 eV
Infrared 700 nm – 1 mm 430 THz – 300 GHz 1.24 meV – 1.7 eV
Microwave 1 mm – 1 meter 300 GHz – 300 MHz 1.24 µeV – 1.24 meV
Radio 1 mm – 100,000 km 300 GHz – 3 Hz 12.4 feV – 1.24 meV

Hello AFN :) I've go a rookie question to which I found numerous suggestions but I think in this thread I will get the best answer. I feel uncertain to put my seedlings under my 90W LED panel since it has been only few days after they sprouted. Both seedlings are just oven an inch high. Do you recommend to put them under the light right the way or I should give them some time, perhaps an extra week under the natural sunlight ?
