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.

With single coloured LED lights, scientists at PlantLab are using the exact coloured that lights plants need for photosynthesis.

According to the project overview, “Plants mainly need blue and red light for photosynthesis and far-red, a colour not even visible to the human eye but visible to the plant. The relationships between the light colours determine the form of the plant.”
 
Asides from minimizing soil erosion, their new system of indoor farming has the added benefits of reducing water waste by 95% and eliminating pesticide use.
