In the largest agriculture-tech funding round in history, vertical farming startup "Plenty" attracted US$200 million. Some experts say the investment could make the indoor farming industry more viable as a whole. Instead of growing greens outdoors, the farm grows its food on glowing, LED-lit 20-foot-tall towers inside a former electronics distribution center in South San Francisco. The towers don't require pesticides or natural sunlight. The technique is called indoor vertical farming. Food grows on trays or hanging modules in a climate-controlled, indoor facility. The process is revolutionary. Certain types of food could be produced year-round, anywhere, in a small space. http://www.businessinsider.com/food-investment-vertical-farming-2017-8/
