Aeroponics is an alternative form of gardening in which you’re growing plants without soil. Unlike hydroponics or aquaponics, though, which use their own soilless methods, aeroponics leaves plants’ roots hanging in the air while they get a periodic misting of nutrients and water. It may sound complicated, but it’s easier than ever to start an aeroponics garden in your own home, especially with the ever-increasing accessibility of tools to help you start.
