Title: Hydroponics growing conduit

Abstract: A combination of a rigid trough formed of a bottom and raised sides and a conduit which carries the water-nutrient solution to plants contained therein, the conduit being contained within the trough and being placed in the trough sufficiently spaced between the sides thereof to permit access to the underside of the conduit. A Dike Stick is so sized to fit under the conduit in one situation to provide a partial damming effect and to fit on top of the conduit by bridging the sides of the trough.
