Greenhouse Production Systems
Hydroponic Systems
Aeroponic System
In the aeroponic system, the nutrient solution is intermittently sprayed onto the roots of plants that otherwise hang in the air (Figure 15.5). The A-frame aeroponic system is constructed of polystyrene board sides supported by a frame above a nutrient reservoir. The plants are inserted into the holes of the polystyrene sides and secured using polyurethane foam, with their roots suspended on the inside of the A-frame. The box is sealed so that the roots are in darkness (to inhibit algal growth) and to maintain humidity. The roots of the plants get good oxygen from the spray of solution and from the volume of air within the chamber.
