Reportedly, Netherlands-based PlantLab has taken advantage of red and blue LED lights to produce beans, corn, peppers, zucchini, tomatoes and strawberries in an automated indoor farm, which could lead to more efficient indoor food production, especially in climates with short sunlight hours.
Netherlands-based PlantLab believes their work with LED technology could lead to more efficient indoor food production and allow more growing options for farmers in climates with shorter daylight hours.
Indoor farmers have been using LED lights for years because of their tendency to increase photosynthesis in plants and their ability to remove some bacteria and viruses. They are also a lot more energy efficient than traditionally grow lights. But probably the main reason LEDs are popular with indoor plant growers is that they provide just the right frequency to encourage growth.
According to the project overview, “Plants mainly need blue and red light for photosynthesis and far-red, a color not even visible to the human eye but visible to the plant. The relationships between the light colors determine the form of the plant.”
