In the star in the film, there are many plants in the space station is the astronaut, let the plant growth light station in space by using plant growth, such as the 2015 film The Martian (Jedi rescue), is through the planting crops and soil on Mars LED lamps produce a vegetable garden.

Similar plots may be achieved in the future, and no soil is needed at that time. Through the control of planting environment (CEA) system, with the least energy and water, using LED to replace fluorescent bulb, ignore climate, location or season, planting plants in any place, food can not only ease the problem more and more urgent, can also be used in the space station, let the pilot can eat fresh vegetables.

The international space station (ISS) astronaut in 2014 launched the "Veg-01" space farm, the successful use of red, blue and green LED light training the first batch of red vine dishes, also in 2016 to make space Zinnia flowering, when the United States National Aeronautics and Space Administration (NASA) said, hoping to grow tomatoes in space in 2018.

Canada University of Guelph (Guelph) is the development of relevant technology, hope the astronauts can be on the moon or is planted on Mars, and improve the quality of life of the astronauts, the controlled environment system of equipment center (CESRF) is looking for astronauts in the long-term task for planting plants, and as the moon and Mars earth pressure is relatively small University of Guelph, is devoted to the study of decompression of the greenhouse.

There is no guarantee to have enough sun in space, so it is necessary to grow plants through plant growth lights and different spectra. With the evolution of LED technology, its luminous efficiency and power are higher and higher. Besides street lamps and car lights, it can also be extended to plant lamps. Nowadays, it can be used as the only source of lighting for plants.

LED chip device is different to send a specific wavelength of light, the same plants have different flavor and pigment accumulation in different light, the secondary metabolites of plants (Secondary Metabolites) will have different responses to these changes in wavelength, improve plant mouth feel and drug research are very helpful.

Therefore, besides studying the space plants, CESRF of University of Guelph is also working with the pharmaceutical plant industry, LED industry and other CEA system companies. It hopes to provide technology for the field of medicinal plants by multi-party cooperation.
