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.\u003c\/p\u003e\n\u003ch2\u003eCut-to-length lightproof duct in 4, 6, and 8 inch diameters\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eIt 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.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% Lightproof:\u003c\/strong\u003e Blocks light leaks in and out of the exhaust run during dark cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-Absorbing Black Wall:\u003c\/strong\u003e Pulls heat off the airflow for the cooling setup to exhaust.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated to 140°F:\u003c\/strong\u003e Handles high heat, humidity, and heavy CFM without fatigue.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKink-Resistant:\u003c\/strong\u003e Bends around tents and racks without collapsing the airway.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut-to-Length + Clamps:\u003c\/strong\u003e 25-foot sections trim to fit, with clamps included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%; border-collapse:collapse;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color:#333; color:#fff;\"\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:8px; text-align:left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eType\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eBlack lightproof flex ducting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eDiameters\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e4\", 6\", 8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eSection Length\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e25 ft (cut to length)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eLight Blocking\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e100% lightproof\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eMax Temperature\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e140°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eClamps\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eIncluded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color:#fff;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eStandard inline fans and carbon filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"GrowersHouse","offers":[{"title":"4\" x 25'","offer_id":43669779972163,"sku":"DUC-49","price":5.8,"currency_code":"USD","in_stock":true},{"title":"6\" x 25'","offer_id":43669780004931,"sku":"DUC-50","price":8.85,"currency_code":"USD","in_stock":true},{"title":"8\" x 25'","offer_id":43669780037699,"sku":"DUC-51","price":11.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2082\/5769\/files\/Common_Culture_Black_Lightproof_Ducting_w_Clamps_main_image_1050_x_1050.webp?v=1786648199","url":"https:\/\/happyhydro.com\/products\/common-culture-black-lightproof-ducting-w-clamps","provider":"Happy Hydro","version":"1.0","type":"link"}
