Aeroponic plant growing apparatus which includes an elongate vertically oriented plant chamber having a plurality of plant receiving apertures through its side wall. Stationed at the top of the chamber are one or more spray nozzles through which nutrient solution is sprayed into the chamber, thereby wetting the roots of the plants stationed in the apertures. The apparatus includes structure by which fresh atmospheric air is inducted into the chamber and stagnant air is exhausted during the spraying of the plant roots. In a preferred alternative the motive energy for this air induction into the plant chamber is provided by the spray nozzle(s) and an air induction manifold cooperates with the spray nozzle(s) to establish a low pressure Venturi zone therebetween.

[ What is claimed is:] [1.] Aeroponic plant growing apparatus comprising:(a) an essentially vertically oriented elongate plant chamber having upper and lower ends and a tubular side wall, said chamber having a bore defining a plant root receiving zone and said side wall comprising a plurality of plant receiving apertures therethrough;(b) spray means comprising at least one spray nozzle stationed at the upper end of said plant chamber, said spray means being oriented to spray liquid plant nutrient solution downwardly through the bore of said chamber, thereby to wet plant roots residing within said zone;(c) means to supply liquid plant nutrient solution to said spray means; and(d) means to induct atmospheric air and to exhaust stagnant air from said chamber during operation of said spray means.
