Year-round illuminated greenhouses are starting to catch on, especially in places with cold, dark winters that aren’t great for growing crops. Maybe you’ve bought produce or herbs cultivated at one of these “plant factories.” One problem with this kind of closed-environment agriculture is that it takes a lot of energy to replace the light that outdoor plants get from the sun’s rays.

University of Florida horticultural scientist Kevin Folta and his team started wondering if they could tweak the usual cycle of alternating long bright “days” followed by long dark “nights.” By playing around with how long plants received light and darkness, they may have discovered a way to trim the power bills for indoor growers.

Micro-naps for plants: Flicking the lights on and off can save energy without hurting indoor agriculture harvests

Kevin M. Folta, University of Florida

Indoor plant factories have high energy costs since LEDs replace the sunlight outdoor plants get for free. Scientists found a way to dial back how much light is needed by breaking it into tiny bursts.
