Many people have heard of hydroponics and aquaponics, in which plants are grown in some type of medium and nutrients are delivered via water based solution. Aeroponics has emerged in the last decade as a solution that uses no medium (the roots simply dangle in the air) and has minimal water requirements as nutrients are delivered via misting in an enclosed space. Modern Farmer has an excellent article that explains the technology in layman’s terms and they note that naked roots thrive; when eliminating growing medium, plants grow faster.
As you might imagine, production can be accomplished on a small footprint, in diverse climates, that allows a dependable food supply without disruption due to environmental changes, weather events, pestilence, or supply chain failures.
