The Pressure Compensated Dribble Ring is a simple, effective way to evenly water a large pot or container. The 4" diameter, low-profile tube consistently releases water at 2 gph, ensuring a well-watered, but not overwatered, plant.
The PC Dribble Rings are great for nursery stock, B&B (ball and burlap) stock, and large containers. The ring's larger body design is accurate, reduces clogging, and have a controlled output that remains constant from 15 to 50 psi.
