Hydroponics: Aeroponics Systems

In aeroponics, the nutrient solution is supplied by a time-activated pump beneath the foliage.

Aeroponics systems comprise one of six basic types of hydroponics, or soil-less, gardening systems.
Myths about hydroponics systems suggest that they are too complex, too technological, too expensive, or environmentally unfriendly. None of these myths are true. Hydroponics gardening systems have existed since the time of the Egyptian Pharaohs, they are simple and affordable, and they offer more ecological benefits than traditional gardening.

In some hydroponics systems, the plants’ roots are submerged in a nutrient solution which is periodically drained to aerate them. In aeroponics, the nutrient solution is supplied by a time-activated pump beneath the foliage. Water infused with needed minerals and vitamins is misted up into the roots by the pump. After misting, the roots are allowed to air out. Aeroponics is similar to the nutrient film technique (NFT) in its method of aeration, but more complicated in other respects.

Aeroponics systems can function without frequent supervision. Cycles are timed for every few minutes,
and you only need to make sure that the roots receive sufficient exposure to the nutrients. Once you have done that, you can attend to other things. The important thing is to make sure that the roots don’t dry out; the misting cycles must be precise and not interrupted.

The drip option is the most common hydroponics system in use. The nutrient solution is dropped onto the plants from above by pipes. Other gardeners, however, like the ebb-and-flow system, which uses a timed mechanism to submerge the roots then to return the unused solution back into a reservoir beneath the roots. The advantage of this method is that the nutrient solution can be recycled. Many growers choose this method for its ecologically sound design.
