For space astronauts, each space exploration will have a long stay, and their food is brought from the earth to the space. Many scientists have been studying how to grow vegetables in space. Recently, the research team at the University of Guelph is dedicated to the development of an LED technology that allows astronauts to grow vegetables in space at the most efficient rate. The research team is investigating technologies that use LEDs to optimize plant growth. LED lights can be used to generate the specific wavelengths necessary for plant growth, most notably the efficiency of LED lighting. When resources are scarce, you can get many photons with less energy. The researchers used lettuce for testing in the experiment because the plant grew easily and grew rapidly. They will use research to improve the growth of more nutritious crops such as strawberries and sacred fruit. Researchers believe that the peculiar method of LED light source will be widely used in the future, allowing astronauts to plant a large number of vegetables in space. The goal of this study was to test to see which specific wavelengths are optimal for the growth of various plants. The resources of any interplanetary mission are bound to be limited, so energy efficiency is the key. The smaller the weight we send into space, the better we need to carry the interstellar missions, and the astronauts can't travel to the food store halfway to Mars.
