Concerned from astronauts in space, every residence time of space exploration will be very long, and their food is brought to the earth from space, many scientists have been studying on how to grow vegetables in space. Recently, the research team at the University of Guelph is committed to developing an LED technology, which enables the most efficient speed astronauts in space to grow vegetables.

The research team is studying the use of LED enable plant growth optimization technique, LED lamps can be used to produce specific wavelength necessary for the growth of plants, is the most valued LED lighting efficiency. When a shortage of resources appear, you can get a lot less energy to photons.
The researchers used lettuce tested in experiments, because such plants are easy to grow and the grown rapidly. They will use the findings to improve more nutritious crop growth, such as strawberry and cherry tomatoes and so on. Researchers believe that peculiar method will be widely used LED light source in the future, so lots of vegetables grown astronauts in space.
The objective of this study is to see what is the best special wavelength that most suitable to the plant growth. Any interplanetary missions are necessarily limited in resources, so energy efficiency is the key.
