Aeroponics

from Wikipedia, the free encyclopedia
NASA aeroponic culture

The aeroponics is a hydroponics -Anbaumethode for plants. The plants are fixed in such a way that their roots are constantly wetted in a closed container with an aerosol of a hydroponic fertilizer solution made from water and nutrients . The solution is nebulized with the help of nebulizers (low pressure, high pressure and ultrasonic nebulizers ). The method is also well suited for root vegetables such as potatoes, carrots or medicinal plants , whose nutritious components are stored in the roots.

The method was developed by KT Hubick in 1982 and later improved by NASA scientists. The method is also suitable for growing plants under conditions when there is little or no gravity , i.e. especially in space travel. An additional advantage of the hydroponic method is that less water is required in the circuit than with the other methods.

Aeroponics is nowadays mainly used for rooting cuttings because of the enormous root growth , because with this method the roots grow stronger and faster than the above-ground parts.

The disadvantage of the ultrasound process is that fertilizer salts crystallize out on the ultrasound membranes and this leads to blockages.
