Without a self-circulating production system, we cannot live long in space. The gardens on earth may be unruly and messy, but in space, we always need the vegetable fields to work like good machines. This is the researcher at Purdue University is using LEDs scientifically.  The reason why the lights mix light to produce delicious crops. Gary Mitchell, a professor of horticulture at Purdue University, said in a statement: "Everything on earth is ultimately photosynthesized by sunlight." “The problem we face is how to replicate in space, generate our own light source with limited energy, and target LEDs.  Lighting is the best choice. †We have long known that LEDs use far less power than conventional high-pressure sodium lamps for every additional illumination. But if we can figure out exactly what proportion of the visible spectrum will make the plants absorb well, we can theoretically further reduce the energy consumption of the space garden. As far as lettuce is concerned, at least the magical panacea seems to be to place red and blue lights on the roof at a ratio of 95:5. A new scientific study by Mitchell found that this special hybrid light saves 50% of energy compared to using fully covered led lights and 90% less energy than traditional light bulbs. When it comes to sending humans to live on Mars, we have to be more serious, so the technology to grow plants outside the Earth must be perfect. If we want to build a self-sustaining colony on this red planet, or to send astronauts to further space for missions, we need not only space gardens to feed settlers, but also the ability to recycle carbon dioxide, oxygen and water. Independent sustainable ecosystem. NASA has acknowledged this need and has focused on the Recycled Food System on a recent research development draft. But life in space is not the same as life on earth. There, we take it for granted that resources, including sunlight and air, are very precious and non-renewable. Space farmers face enormous challenges, such as the traditional means of using 600-1000 watt bulbs to simulate sunlight and stimulate plant growth in a closed environment. Traditional lighting can also generate excess heat, which can cause plants to dehydrate or burn if they are not careful. Researcher Lucy Polit said, " Lighting accounts for about 90% of energy demand. If you use traditional lighting to grow plants, you need a nuclear reactor to feed four people." Both cannabis growers and future space farmers have found that LED lights that emit only visible light are the best choice. Plants throw away most of the sun's energy, and evolution has made plants prefer to absorb red and blue light in all colors. After laboratory modifications, the researchers found that lettuce with a little blue light and a lot of red light produced the highest yields, cutting energy consumption by ten times. Mitchell's research team still has a lot of work to do, such as studying how to increase or decrease light during the entire life cycle of a plant. Once the optimal green leafy vegetable illumination process is in place, scientists will begin to study more of the plant's required light, such as tomatoes and corn. The current cosmic menu may have only vacuum-packed food, but when you start to go to Europa's maiden voyage, ordering a fresh salad may sound unusual. ZTTEK Electric Scooter Batteries.
