Q&A: Inside the World's Largest Indoor Farm
A Japanese company's futuristic approach to farming could revolutionize how we grow our food.
An abandoned Sony factory in Miyagi Prefecture, Japan, has been transformed into what could very well be the farm of the future.
Shigeharu Shimamura, a plant physiologist and CEO of Mirai, has constructed the world's largest indoor farm—25,000 square feet of futuristic garden beds nurtured by 17,500 LED lights in a bacteria-free, pesticide-free environment. The result? About 10,000 heads of fresh lettuce harvested each day.
