Abstract
An improved miniature watering unit is disclosed, which has a cylindrical body attached to a source of pressurized water, having one or more water discharge openings and a rotatable cap. As the cap is rotated, a stem is raised or lowered to form an arcuate orifice of variable circumferential width between the stem and the interior of the body. The adjustment in width of the orifice in turn adjusts the rate of water from the discharge openings.
