One thing I’m curious about this from the plant perspective - we’re pretty sure we’re passing everything relevant down to the plant, but nature doesn’t normally leave signal or energy lying around without leveraging it somewhere, so what don’t we know about how the broccoli use the parts we’ve been assuming they don’t?
Industrial (or home) grow lights are often already red and blue spectrum focused since those are most efficient for photosynthesis. There’s plenty of research on those if you’re curious
As far as I know, plants are not usually limited by sunlight, but CO2. Grabbing more wavelengths is not going to improve their growth potential.
Plants are green because they _reflect_ non-magenta light! This energy is wasted. If you saw artificial grow lights, they are now often magenta-colored exactly because the green part of the spectrum does nothing, and you might as well save some energy.

These panels absorb that light before it gets to the plant, so it's a win-win.
