Urban.ag is a rooftop farming startup based in Seattle that was founded in 2010. It designs sustainable and efficient rooftop agriculture systems that keep costs low while yielding high. A 10,000 square foot urban farm mitigates 85 tons of CO2 annually while producing over 100,000 pounds of food with 93% less space and 89% less water than traditional farming. The system is designed to be constructed in weeks and harvests continuously. It aims to create local jobs and reduce pesticide usage to achieve long-term human sustainability in urban centers.
