Aeroponics is a system where often no media is present and the roots of the plants are misted with the nutrient solution in a chamber or other suitable space. The mist has to be of a certain size (5 micron max) to maximise growth and the delivery of the mist is a problem in its own right.
Aeroponics is less suitable for commercial production, due to blockages that can occur and high pressure pumps are often required. However, there are occasions where aeroponics is used for research and in some ‘niche’ applications.
The lack of any media in aeroponics and the subsequent lack of buffering can be problematic. However, aeroponics is a fantastic system when clean, fresh roots are required.
