Most sunlight is not red or blue; most of it is either infrared, green or ultraviolet. Plants absorb red and blue light. If you could capture all the energy from the sun with a solar panel from the future, then it could power many more lettuces if you transformed all that energy into the important wavelengths rather than waste it in heating the floor and making leaves look green and pretty to the human eye.
