Their chloroplasts only conduct photosynthesis for a narrow bandwidth of light, which a grow lamp can deliver. They need the appropriate spectrum of light," he explains, adding that plants are actually quite choosy in this regard. "Technically, plants don't need sunlight. "Grow lights let indoor growers of any scale bring the right spectrum of light to their plants," says Roger Buelow, the chief technology officer at AeroFarms, a high-tech vertical farming company that grows produce indoors year-round. Unlike the bulbs in chandeliers or sconces, grow lights emit a spectrum of light that's similar to the sun.
