Figure 9.8 - Aeroponics can be classified as a branch of hydroponics,
but in recent years it has become something of a method in a field of
its own.
These systems are generally expensive and are used by
professional growers. The unit itself can be recognized straight away
by its design. The plants are grown in a medium that is placed into
slots along a lengthy tube. The tubes can run anywhere from 1 meter to
20 meters in length. Inside the tube are nozzles which mist down the
roots of each plant with grow nutrients. The reservoir, which contains
nutrients, is kept outside of the tube in a tank. The nutrients are
pumped from the tank to the nozzles and then the remaining solution
that drips from the plants is drained into another tank that is normally
checked before being reused again.
