Rhizome, nice to see respond from you
Have a look at these graphs Chlorophyll a, diethyl ether
Lightening is more ciomlex than I thought. I have never been in biology that far since I was at school.
Basically all light from sun is used for plants growth. For example Table 3
The aim iz to determine peaks for all of plant pigments, accesory cells and light harvesting complexes, then to find out the proportion of content in the plant in order to combine led lighter using leds with known wavelenghts to meet this proportion, this will ensure absolute lightening so all plant cells will be driven in action.
For example:
chloro a peaks at 420 660 nm number of cells per cm^2 100 (say we need 100 leds)
chloro b peaks at 430 525 nm number of cells per cm^2 50 (we need 50 leds)
PSII triggered by 680nm light number of cells per cm^2 4 (we need 4 leds)
this is just simople illustration of what I mean.
But there are more factors that can affect light spectrum such as veg, flowering, etc
cture Reviewed by cture on . Light spectrum research Due to my LED total fuckup :)) i had carried out a little research. Used various sources, and they state various date for instance Alphabetical Index of Photochem CAD Spectra different absorbtion spectra for alfa in methanol and ethil. Here is tha spectrum I have figured out for now. chlorophyll a 420 660 chlorophyll b 430 625 b carothene 450 P680 Photosystem II Rating: 5
