From what I have read, (in aquarium plant books) plants will alter
thier pigment depending on the available light..... It's kind of like a
plant metabolism. This is also a very good indicator of your plant's
light requirements. I thought this was very cool stuff!!



or just the opposite. The plant is not getting enough light, so it is
getting pale. The long internodes and also indicate not nearly enough
light.
