Re: Green light
I enjoyed your post George... if anyone is confused please look on page
21 of Aquarium Plants by Barry James (or any Plant Physiology textbook).
Photosynthetic plants clearly absorb light in the green part of the
spectrum... just less efficiently than in the red or blue region. This is
why plants appear green. It was always explained to me that red pigment
in a plants photosynthetic organs is a protective measure in response to
strong light.
On another note, many aquatic plants have the ability to double in
size every 2 to 4 days under optimal conditions... to see an ad boasting
of 6" growth after several weeks is truly hilarious... what is amazing to
me is that the plant actually survived that long under such obviously
inadequate conditions!
