Abstract: A fog generator includes a reservoir for a liquid to be atomized, a plurality of ultrasonic transducers disposed in spaced relation to each other in the reservoir so as to be submerged within the liquid therein, a gas inlet duct extending through the reservoir, and a dome-shaped deflector overlying, and of larger diameter than, the gas inlet duct to deflect the gas flowing through the duct back towards the reservor to pick up liquid atomized by the transducers.

Abstract: An apparatus for aeroponically growing plants, having a housing including a partition defining an upper compartment and a lower compartment, the partition including means of supporting a plurality of plants. The apparatus comprises a fog generator including a container for receiving a quantity of water, and a ultrasonic transducer located within the container to be immersed in the water when received therein, and thereby to generate a fog in the upper end of the container. Also having conduit means to direct the generated fog to the compartments of the housing.
