Inside the sprawling warehouses where some indoor farming startups grow food under artificial light, custom “light recipes” adjust the color of LEDs to help plants grow faster. Even with efficient LED bulbs, the systems still use a huge amount of energy. But new technology designed for traditional greenhouses can manipulate sunlight in a similar way, without any use of electricity at all.
On greenhouse roofs, a film filled with quantum dots shifts UV light from the blue portion of the spectrum to red. The orange glow that the film emits helps plants grow.
