An automatic cloning apparatus is disclosed which comprises a housing having an interior divided into a plant compartment and a water compartment. The plant compartment has a plurality of porous net pockets adapted to allow plants to rest thereon and water to drain therethrough. Above the water compartment is a mixing area having a mist generator thereon. The mist generator is mounted to the housing and has a motor with a hollow tapered shaft extending downwardly therefrom into the water compartment. The shaft is tapered whereby when spinning rapidly, the combination of centripetal force on the water and the outwardly sloping inner surface of the tapered shaft forces water upwardly therein. A disk is mounted atop the open upper end of the tapered shaft and adapted to receive water therefrom. The disk throws the water off in a radial movement in small droplets in the mixing area and also forces air within the mixing area outwardly throughout the mixing area. This action mixes the air and the water within the mixing area and forces the resultant mixture through the cage to the plant compartment in a fine mist.
