The plants simply do not use green light, to them it's as if it does not exist
This a scientific proved false statement.

Plants use green light, although they are less sensitive to it than to other wavelenghts. Green light can stop the flowering stage, but more intensity (in micromols, not in lm) or duration of green light are required than any other wavelenght. So, if it absolutely neccesary to check something during the dark period, the best is use green light, because plants are less sensitive to it and because humans have the max sensitivity to green light.

But dont think green light is safe, it isnt. Use it at the minimun possible.
