Serra aeroponics. How does it work?
Now not many people are surprised seeing the plants grow lush outside a substrate, with the roots dangling. 
Remains any case be considered in many ways a technique futuristic that dell'aeroponica, in which a mist of nutrient solution is sprayed directly on the root system allowing considerable water saving, labor and fertilizers.
The aeroponia can remedy some flaws hydroponics, where it is sometimes possible to find an environment that is too wet (and consequent formation of mold and algae) and in case of open systems "lose" the risk of pollution from fertilizers or of substrates (such as the rock wool, in case of growers who act in a manner little ethics).
Additionally, the use of water is truly reduced to lowest terms.
In contrast, the aeroponics is difficult to achieve a simplified and inexpensive, and requires an initial investment in equipment and staff training.
Let's look at the materials used in a greenhouse for the production on a large scale.
PVC conduits: they are in fact containers for plants, robust and hygienic have a lifetime almost eternal. It esistone in different shapes and sizes suited to any type of cultivation (horticulture, floriculture, vines, small trees, herbs). PVC is a recyclable material.
Pipes and Sprayers: the tubes are also made of PVC and are not afraid wear. The nutrient solution that passes through them is pumped from the tanks to reach the sprayers dirazionali that, regulated by a solenoid valve, will provide to the spray of the roots.
Drainage: as in hydroponic systems with gutters, unused solution is then returned, collected and reused due to the slope of the structure.
Panels: a styrofoam perforated lining the canals and provide support to plants, protecting the roots from light. 
Control system: the brain of the greenhouse is technologically advanced and allows you to adjust all parameters ressochè environment. Irrigation, fertilization, pumping, drainage and so on are settable from the control panel can be interfaced with PC.
