Lower leaf temperatures, create instant humidity, and cool down air temperature with the mister system. The Mister Assembly includes a preassembled mister and riser with 1/4 in. barbed inlet that is ready to install. Works when installed upright or upside down. The fan-spray emitter delivers water in a full-circle pattern at 4-7 GPH and radius of up to 1-1/2 ft. (at 15-50 PSI). Adjust from fine to heavy mist with a twist of the dial. Use the attached 1/4 in. barbed inlet to connect to 1/4 in. supply tubing. Mister and riser are made of polyethylene treated with UV inhibitors.
