Miyagi Prefecture, Japan, a factory half the size of a football field, with 17,500 LED lamps grows lettuce on 15 levels. Each day 10,000 heads of lettuce are produced, using 1% of the normal amount of water needed for the same crop yield.
An advanced system that controls water irrigation, air humidity, air flow & overall temperature allows the factory to produce the ‘perfect’ environment for lettuce to grow and speed wise it beats its outside cousin by 2.5x!
