Why green lights are bad for plants?
There is a reason why plants appear green. Inside a plant, the plastid chloroplast contains green pigment that reflects green light. This means that plants do not use green lights in large amounts (there are some other plastids that uses the color green, but there are few in number). So when you give plants green light, they cannot use it as efficient as they would if it was a different color.

So, your eyes only see the green or the red wavelengths.
