Abstract: A method for aeroponically growing plants which involves an elongate vertically oriented plant chamber having a plurality of plant receiving apertures through its side wall. Plants are stationed in the apertures with their roots extending into the bore of the plant chamber and nutrient solution is sprayed downwardly into the chamber to wet the plant roots. During the spraying of the plant roots atmospheric air is inducted into and stale air exhausted from the chamber. In preferred alternatives of the method the motive energy for the air induction is provided by the spraying step, the nutrient solution is sprayed as a mist and the spraying is undertaken cyclically.

Abstract: 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.
