Why grow lights for house plants are never green?
first off, plants are green meaning they dont absorb green wavelengths, they reflect it off which is what we see. secondly they need yellow/red colored light in order to perform photosynthesis since they absorb those colors. the sun viewed through our atmosphere appears yellow, not green.

Cyan light results. Green and blue and red lights are all primary colors of light. Because red is not part of cyan light, cyan and red light are complementary colors.
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.

How do disco lights work?
They have color filters. A red filter, for example, transmits only red light that is emitted from the white light bulb.

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