If this is so then I think that the "middle" part of the spectrum (the one that makes the color of the light pleasing to the eye) is not completely useless for the plants. Look at all these graphs for the wavelengths that are best for photosyntesis. They all differ a little from each other. But what is pretty obvious is that between the high blue and red spikes there is also some activity. Meaning that the green light will actually be beneficial to some degree.
Yes exactly what I mean. Thank you

I currently use a colormax to supplement my red spectrum. Its a far weaker light in terms of intensity. Now I really want to experiment with that purple and mixing green. I'm just worried about intensity and usefulness. Or if its so insanely ugly, maybe I can turn it on when I leave.
