ABSTRACT
This chapter describes the practical aspects of how an aeroponic system functions and the key factors associated with its practice. There is a heavy emphasis on the nutrients needed to grow strong and healthy plants. A description by element is included—the macro and the micronutrients—that are necessary for photosynthesis to occur. The root uptake mechanisms and essential chemical ingredients present in a nutrient solution. The key features of a commercial aeroponics system are listed and described. These features include nutrient tank, pumps, and associated plumbing. The quality of water and the concomitant sensors needed to monitor and control the daily operation of commercial operation are described. These sensors include ones that can measure continuously pH, electrical conductivity, water and air temperature, humidity, and CO2. The need for the development of robust sensors for measuring specific nutrient ions (nitrate, phosphate, potassium) is also discussed.
