aeroponics

Aeroponics is a method of growing plants by suspending their roots in the air and spraying them with nutrient solutions. This technique is a form of controlled environment agriculture (CEA) and is one of the soilless methods used in modern vertical farming.12

Vertical farming involves growing crops indoors in stacked layers without soil. While historical examples exist, modern vertical farming, conceptualized in the late 20th century, aims to produce food in urban areas using human-made conditions. Aeroponics, developed by NASA, is one of the systems used, alongside hydroponics and aquaponics. This method allows for year-round crop production with potentially reduced water usage and fewer pesticides, though it requires significant electricity and has high start-up costs.2
