Have You Seen The World's First Indoor Vertical Farm Yet? ​

Behind a bright blue wall, which seals a former highway tunnel, stretches a massive indoor farm bathed in rose-tinted light. Fruits and vegetables grow hydroponically, with no soil, in vertically stacked layers inside, illuminated by neon-pink LEDs instead of sunlight. This high-tech facility in South Korea is the world's first indoor vertical farm built in a tunnel. It's also the largest such farm in the country and one of the biggest in the world, with a floor area of 2,300 square metres (25,000 square feet), nearly half the size of an American football field.
