World's largest vertical farm gets big harvests at accelerated rate

A laboratory worker in full biohazard gear is patrolling rows of rainbow colored LED-lit shelves. The shelves stand about 2 meters and have six levels, each containing trays of lettuce saplings bathing underneath the light, and the room is illuminated in a psychedelic pink.

This is no scene from a science fiction movie, but a common sight for scientists at a plant factory in Anxi, Fujian province, which covers 1 hectare and is the largest vertical farming complex in the world. The second-largest is a 0.64 hectare farm in Newark, New Jersey.
