In aeroponics, the roots of a plant are suspended in a darkened chamber and periodically covered with a mist or fog of nutrient solution.
No solid medium is used. Traditional aeroponic techniques use pumps and misters more commonly found in micro-irrigation systems, whereas state-of-the-art techniques employ ultrasonic nebulizers which render the nutrient solution into an extremely fine fog. The Land Exhibit at EPCOT Center has aeroponics in vertical sections of large-diameter plastic pipe. Plant are placed through holes drilled in the side of the pipe so roots are inside.
The pipe sections are suspended from the greenhouse ceiling and move continuously around the greenhouse on a motorized system. Periodically they pause under a mist nozzle to be irrigated. Aeroponics may be the best method for plants with thick roots such as trees. Thick roots may not get adequate aeration in static or flowing systems.
