: the growing of plants by suspending their roots in the air and spraying them with nutrient solutions
Hydroponics allows us to grow plants in a water-and-nutrient solution, while aeroponics grows them in a nutrient-laden mist. Dickson D. Despommier, New York Times, 24 Apr. 2009
Fog can actually carry dissolved nutrients for growing plants aeroponically, suspended in the air, with their clean roots dangling in the fog. Marshall Ingwerson, Christian Science Monitor, 1 Mar. 1985
