Plants need other frequencies to signal different chemical processes, they don't thrive if just fed blue light.

There is a lot more to it than just chlorophyll absorption. I've been looking into this lately with regard to saltwater aquarium lighting, and it's pretty complicated stuff. Google "McCree curve" and "Photosynthetically active radiation" for (much) more.

You should check out the resources at http://www.reddit.com/r/HandsOnComplexity, there is a lot of great knowledge about plant lighting there!
