Lately I'm reading a lot about vertical farming. Wiki defines it as "a component of urban agriculture" and "the practice of producing food in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures. (such as buildings and skyscrapers)" https://en.wikipedia.org/wiki/Vertical_farming Also this article predicts that the market is estimated to reach USD 3.88 Billion by 2020, which is huge growth for a market that barely exists. http://www.marketwatch.com/story/ve...h-388-billion-usd-by-2020-2016-01-13-82033123 What do you think about vertical farming? Could it become the trend that would define the future agriculture?
