The yields of some crops can be substantially boosted by covering them in a material that increases the amount of red light they receive. The simple technology could help to feed the world’s growing population, although more research is needed to see if it affects the flavor and nutrition of plants.
Red wavelengths of sunlight are known to be the biggest drivers of plant growth because they stimulate leaves to produce chlorophyll, which is needed for photosynthesis. So this causes more yield in the sector.
