Growing food on Mars for long-term space exploration has many benefits including reduced costs and fuel requirements for lift-off, increased nutrition and psychological benefits for astronauts, and oxygen and water regeneration. However, there are also many complication including potential threats caused by the thinner atmosphere, which would force production underground or into a heavily armored base. Fiber optics and concentrating mirrors for photon delivery provide a more efficient system than more traditional electric systems. This technology transmits solar radiation, and the spectra can be altered by tuning the mirrors to only transmit photosynthetic photons. In order to reduce heat loads and optimize food production it is important to determine whether ultra-violet and far-red photons should be included or excluded from this system. The photons in this range can be either beneficial or detrimental depending on the crop, timing and intensity
