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.
