Aeroponics is the process of growing plants in an air or mist environment without the use of soil. The basic principle of aeroponic growing is to grow plants suspended in a closed or semi-closed environment by spraying the plant's dangling roots and lower stem with an atomized or sprayed, nutrient-rich water solution. The environment is kept free from pests and disease so that the plants may grow healthier and more quickly than plants grown in a medium.
Air cultures optimize access to air for successful plant growth. Aeroponics can limit disease transmission since plant-to-plant contact is reduced and each spray pulse can be sterile. Aeroponic equipment involves the use of sprayers, misters, foggers, or other devices to create a fine mist of solution to deliver nutrients to plant roots.Ultimately, the choice is up to the producer. However, there is much room for improvement and the need to supply poor farmers with quality seed continues.
