light is just photons so it does not really make sense that plants need the whole spectrum. So do plants just use certain wavelengths better than others. What about the experiments that were done and people claimed to much blue created a leafy plant. It just does not make sense. I am really lost. I do not think people really know exactly how it works. At least I do not get it. I am lost. I can't make up my mind.
Just like Rackitman said, "There is all this conflicting data out there." I think that is for sure true.
demoreal Reviewed by demoreal on . Drowning in conflicting plant graphs - help! (LED) Still trying to design my LED light through clear understanding and not just mimicking. There is one photosynthetic response curve that shows yellow light has more effect than blue light and that green, while lower, is almost as useful. Other articles say green light may stunt plant growth and that yellow is not much more useful (despite the huge success of HPS). Then there is the photosynthesis action spectrum showing that violet/purple light (400nm) has the highest absorption peak Rating: 5
