Aeroponics has it’s roots in the academic world. Initially developed as a method to study plant root structures in the 1920’s. Richard Stoner brought aeroponics to the commercial world as Genesis Technology in 1983. In 1998 NASA funded Stoner’s aeroponics research, bringing attention to this method of growing.
Research has shown that plants have the highest efficiency nutrient and oxygen uptake when exposed to water droplets between 5 and 50 microns. The High Pressure Aeroponics (HPA) system is designed to produce the 50 micron droplet size. This requires special spray nozzles and a pump system that operates at 100psi. Although setting up an HPA is more complicated and expensive, the benefits are certainly worth it. HPA allows for a faster harvest frequency, uses 98% less water and 1/3 the nutrients of soil and hydroponics systems.
Since the watering system requires precisely timed output, an HPA system requires a higher level of automation in the grow room. To me this is a benefit, I am very interested in automating the environment control to get the best yield from my 4 plant cap (since this is what is allowed for a private grow in Oregon).
