    Sure, but where does the energy for that light come from? If the answer is burning things (this is the most likely answer today!) then you are making the world worse. Renewable answers all go back to the sun so why not use the sun directly and avoid all the inefficiencies from turning the sun into electric and then back into light? Which leaves nuclear - which is dieing because of expense.

      Photosynthesis only uses a couple frequencies. Using solar to generate electricity and feed that into target LEDs can be significantly more efficient.

        while not wrong solar does not use most of the sun either and what plants use is where a large part of the energy is. Plus your add in the rest of the inefficiencies of the grid. So I’m back to not seeing how this can be enough better.

        i’m sure you can grow plants this way I just don’t think you can ever make it a good way
