France's first 'vertical farm' sets its sights on sustainability

There's no soil and no sunshine, just stacks of boxes of microgreens and herbs, robot sprinklers and LED lights at France's first 'vertical farm'. The aromatic plants grown by Jungle company in a hangar in the northern French town Château-Thierry will soon supply the national supermarket chain Monoprix. Eventually, it is expected to produce eight million plants a year without any of them ever seeing the light of day.
