this is missing the point, photosynthesis is an entire different topic than photomorphogenesis.Why green?
Frontiers | Photosynthetic Physiology of Blue, Green, and Red Light: Light Intensity Effects and Underlying Mechanisms
Red and blue light are traditionally believed to have a higher quantum yield of CO2 assimilation (QY, moles of CO2 assimilated per mole of photons) than gree...www.frontiersin.org
Probably a bad idea for photo plants unless you are adding it to the lights on schedule, but not at night!
the former is driven by chloroplasts and the latter by (much more sensible) photoreceptors.
plants don't wake up from photosynthesis but because phytochromes get reverted by PAR light. But not all color get absorbed equally:
You best not advise "white light" in the dark period, because usually these diodes peak at ~630nm and will still have a huge area under the curve for the Pr absorption max at 660nm.
Which is the reason why any generic growlight that is wrong-phased + ungrounded can reveg plants when the diodes dim in the night (unknowingly)
Still, a green monochromatic light can also lead to reveg due to various effects that convert green to red when the photons get scattered.
