Aeroponics is the practice of growing plants with their roots exposed to the air and sprayed intermittently with a fine, high-pressure mist of water containing nutrient-rich solutions. There is no need for soil in aeroponic systems.
The roots of plants grown this way are free to absorb the maximum amount of oxygen, without the restrictions of soil compaction. This allows the plants to generate the oils and sugars that give them their flavour much more efficiently, creating strong, vigorous crops that taste delicious and grow much faster than with conventional methods.
Because any water not absorbed by the plants’ roots is simply recycled through the growing system (rather than evaporating, draining away or getting soaked up by soil), aeroponic systems use a tiny fraction of the water required by conventional growing.
Aeroponics is a particularly useful method for plant scientists and researchers as plant roots are easy to see and access. This means that plants can be regularly observed and tested without impacting plant growth or killing the plant by uprooting it.
