Aeroponics is a substrateless cultivation method in which the plant roots are hung freely in the air and sprayed with a fine mist of nutrient solution. One of the main disadvantages of conventional agriculture is high and inefficient use of water, fertilisers and pesticides. The advantages of aeroponics are:
requires around 95% less water²
around 85% less fertiliser is needed²
pesticides are reduced by around 100%²
Seasonal independence – i.e. fresh and regional production all year round – is a further benefit. Important factors are sustainable development, CO2-neutral production, and the protection of ecologically valuable areas.
