The Netherlands is building its first large-scale commercial vertical indoor farm. It’s expected to serve Europe’s largest supermarket chains with high quality, pesticide-free fresh cut lettuce.

Because it’s a closed growing system, with controlled evaporation from plants, this farms use 95% less water than traditional farms. At the same time, most vertical farms don’t need soil because they use aeroponics or hydroponic systems – these dispense nutrients needed for plants to grow via mist or water.
