Emirates Flight Catering and Crop One Holdings are building Dubai’s world’s largest hydroponic farm. The 130,000-square-foot facility will produce over five tonnes of produce every day (all free of pesticides and herbicides). Even though it is soilless, hydroponics uses less water than traditional farming. The company claims that the technology will use just 320 gallons of water and 100 square feet of land to produce the same amount of leafy greens that traditional farming would require 827,640 square feet of land and 250,000 gallons of water to produce.
