Leafy salad greens grown under banks of LED lights, with mist or drips of water are having their day in the sun. Several top U.S. indoor farms, stacked with plants from floor to ceiling, tell Reuters they are boosting production to a level where they can now supply hundreds of grocery stores.
Plenty, Bowery, Aerofarms and 80 Acres Farms are among young companies that see a future in salad greens and other produce grown in what are called vertical farms that rely on robotics and artificial intelligence, along with LED lights. While the first versions of modern vertical farms sprouted about a decade ago, in recent years the introduction of automation and the tracking of data to regulate light and water has allowed them to get out of lab mode and into stores. Now they are trying to scale up.
