Re: [AGA Member] Red Pigment-K spectrum anecdotes



I have a plant, rotala indica, that grows smaller green leaves in low light and pink or red leaves with more intense light, suppose nutrients and other variables also affect color as other people have the same plant and it is much more intense than mine ever get, and mine is under two 55 watt compact flourescents, new tubes, they have had a month and it's still not hot pink. I am lazy about fertilization and the DIY CO2 maintenance. I have bought cuttings of the magenta plants and put them in my tanks and they fade to salmon pink or green fairly quickly.

Yeah, I'm not saying that the only thing that will grow in bright light are red plants i'm just saying that most of the red plants can only grow in bright light. Because if they are shodowed they will not be able to absorb enough light in order to survive. Think of it as a bunch of dots Green dots abosrb light red ones don't (in every plant their are red pigments and green pigments what determins the colour of the plant is the amount of red to green pigment) so if their are alot of red dots their will have to be alot of light in order for the fewer amount of green dots to pull in enought light for the plant to survive.

But lots of plants live in clear water and even no water
and have lots of green and little or no red.

The reason they only need less green pigment is because
they live in clear open water that lots of sunlight can come throw, thus
they can have less green pigment to survive.
