In addition to the solid responses responses, red light is required to trigger a plants phytochrome system by which it senses the photoperiod.
It's the reason green lights are often used for night-time maintence even though it is used for photosynthesis, contrary to the prevailing bro-science.
Same reason a full moon doesn't cause issues: minimal red.
Figure 30.18.1: Phytochrome system: The biologically-inactive form of phytochrome (Pr) is converted to the biologically-active form Pfr under illumination with red light. Far-red light and darkness convert the molecule back to the inactive form.
