Yeah, the reason indicas have more chlorophyll is that plants darken in response to sunlight, and sativas need more light to trigger that response. So under the same lighting, an indica plant would become darker. Anyway, adding pigment to the plants would just make the pigment absorb light that maybe the chlorophyll would have absorbed. There is also the fact that pigments aren't absorbed through the roots.
khronik Reviewed by khronik on . Changing plants color affects light absorbtion? I have a theory. It is totally untested, just an idea to throw out here. Since a plant's green color is the result of it reflecting back the wavelengths of light that it does not use, could changing the plants color cause it to absorb more (or less) light? For example, satties are lighter and greener than indies, and indies need less light to grow than those greedy sativas.
