AppHarvest Greenhouse, Morehead, Kentucky USA

Will coal-country become an AgTech capital? AppHarvest, the largest greenhouse in the US (2.8 million square feet) uses digital monitoring, sun & LED lighting, recycled rainwater and nonchemical growing practices. All of its irrigation water (360,000 gallons a day) is supplied from rain collected from the roof and stored in a ten acres pond (46 million gallons) basically a three month supply in case of drought. Pest control uses nonchemical biological methods, such as tiny wasps ( Encarsia formosa and Eretmocerus eremicus) to control white flies, the nemesis of greenhouse production.
