US Patent 6984090 Root nutrient delivery system

A system for directing water, nutrients and air to the root system of a plant includes an elongated, hollow housing having a wall member that permits water and air to be transmitted therethrough and which defines an internal cavity with an open top and an open bottom. The system may include a plurality of deflectors that are configured to direct water entering into the open top in a direction toward the wall member so that the water may be passed through the wall member. The system may include an upper flange, which may be coupled to the housing proximate the open top, and/or a lower flange, which may be coupled to the housing and extend upwardly and outwardly therefrom.
