Common Culture Black Lightproof Ducting w/Clamps – 8" x 25'

Common Culture black lightproof ducting for grow room exhaust This ducting blocks 100% of light, so no glow leaks out of an exhaust run during the dark cycle. The black wall also absorbs heat off the airflow, which your cooling setup then carries out of the room. It handles high heat and humidity along with heavy CFM without fatiguing or splitting. Rated to 140°F, it resists kinking through tight bends around a tent or rack. Cut-to-length lightproof duct in 4, 6, and 8 inch diameters It comes in 25-foot sections you cut to the length a run needs, so there is no wasted slack coiled behind the fan. The duct is offered in 4-inch, 6-inch, and 8-inch diameters to match common inline fans and carbon filters. Clamps are included on each length. Growers usually keep the run short and straight to protect static pressure. Match the duct diameter to the fan and filter so airflow does not choke at a step-down.
