A couple things to consider. If you are looking for growth and not just
lighting a tank (which I think we all want)...then just any ol red or blue
won't cut it. Chlorophyll A and B both have absorbtion bands that are not
easily matched with LEDs (or atleast the ones I can find). Also, you NEED
blue for more than just growth. Blue is what the plant uses to in order to
know what direction to grow.

..everything else is wasted as far as growth is concerned.
