THE AEROPONIC SYSTEM
The Aeroponic system is probably the most technologically
advanced of all of the hydroponic systems.
Up
to a certain point, it is similar to the N.F.T., with nutrients
supplied through Humid Air, or as a fine mist.
In
this system, the roots remain suspended and immersed in a Culture
Chamber, or Growing Chamber, where they are sprayed with a mist
of nutrient solution at short intervals, usually every few
minutes.
As
in all hydroponic systems, the solution is taken from its supply
tank by a pump controlled by an extremely precise timer
calibrated for very short irrigating cycles, renging from seconds
to minutes.
Like
the N.F.T system, the aeroponic system is highly susceptible to
energy and pump failures.
If
energy or pump interruptions occur, the plants roots will
dry extremely quickly resulting in total loss.
The
spraying of the nutrient solution can be done by medium or high
pressure nozzles, by high pressure foggers, by ultra-sonic
foggers or even by centrifugal foggers.
Another major problem in aeroponic systems is the blocking of the
orifices in the nozzles and high pressure foggers.
Its
prymary application is in the production of shoots and edible
sprouts.
