Artificial Radiant Sources for a Plant Cultural Sub-system in CELSS

The plant cultural sub-system which is a part of CELSS, such as a lunar base or space station, plays an important role in supplying foods and O2 for residents and in absorbing the CO2 exhausted. Optical radiation is an essential environmental element for plant growth. An artificial lighting system in this sub-system will be used as the optical radiation supplying system. One of the reason is the length of the day in space is quite different from that on earth, so sunlight is not suitable for plant growth. Also, it is very essential that vegetables be supplied reliably and on schedule. In this report, artificial radiant sources now used conventionally were estimated from the viewpoint of plant growth. From the results, it was found that a 3-band fluorescent lamp can be used as a radiant source of the sub-system. This paper also discusses trial lamps, including far-red radiation, which are usually deficient in fluorescent lamps.
