It forms a key part of any grow tent or grow room extraction system, moving stale air out of the grow area while bringing fresh air in. This constant air exchange helps maintain stable temperatures, reduces excess humidity, and ensures plants receive a steady supply of CO₂ for healthy vegetative growth and flowering.\u003c\/p\u003e\n\u003cp data-start=\"460\" data-end=\"758\"\u003eBuilt with a dual-layer construction, Black Combi Ducting features an aluminium inner layer and a tough black polyester outer layer. This design provides far greater durability than standard aluminium ducting while also preventing light leaks that can disrupt the dark cycle during the bloom stage.\u003c\/p\u003e\n\u003ch3 data-section-id=\"ycgkk5\" data-start=\"760\" data-end=\"776\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"777\" data-end=\"1235\"\u003e• Dual-layer aluminium and polyester construction for improved durability\u003cbr data-start=\"850\" data-end=\"853\"\u003e• Prevents light leaks inside grow tents and grow rooms\u003cbr data-start=\"908\" data-end=\"911\"\u003e• Reinforced spiral wire keeps the duct open for consistent airflow\u003cbr data-start=\"978\" data-end=\"981\"\u003e• More resistant to tearing than standard aluminium ducting\u003cbr data-start=\"1040\" data-end=\"1043\"\u003e• Helps reduce noise from ventilation systems\u003cbr data-start=\"1088\" data-end=\"1091\"\u003e• Compatible with most inline fans, carbon filters and ventilation setups\u003cbr data-start=\"1164\" data-end=\"1167\"\u003e• Ideal for hydroponics, soil and coco indoor growing environments\u003c\/p\u003e\n\u003ch3 data-section-id=\"1mcmyku\" data-start=\"1237\" data-end=\"1268\"\u003eHow It Solves Grow Problems\u003c\/h3\u003e\n\u003cp data-start=\"1270\" data-end=\"1590\"\u003ePoor ventilation is one of the most common causes of indoor growing problems. Without proper airflow, heat can build up inside a grow tent or grow room, slowing vegetative growth and reducing plant health. Excess humidity during the flowering and bloom stage can also lead to mould, poor bud density, and reduced yields.\u003c\/p\u003e\n\u003cp data-start=\"1592\" data-end=\"1968\"\u003eBlack Combi Ducting ensures air moves efficiently through your ventilation system, helping remove hot, humid air while bringing in fresh CO₂-rich air that supports strong root development, improved nutrient uptake, and consistent plant growth. Its light-proof outer layer also protects the dark cycle during flowering, preventing stress that can affect yield and plant health.\u003c\/p\u003e\n\u003ch3 data-section-id=\"1qw4ccu\" data-start=\"1970\" data-end=\"1984\"\u003eHow to Use\u003c\/h3\u003e\n\u003col data-start=\"1986\" data-end=\"2459\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1qkbg6r\" data-start=\"1986\" data-end=\"2074\"\u003e\n\u003cp data-start=\"1989\" data-end=\"2074\"\u003eMeasure the distance between your extraction fan, carbon filter, and exhaust point.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1fxdfq7\" data-start=\"2075\" data-end=\"2153\"\u003e\n\u003cp data-start=\"2078\" data-end=\"2153\"\u003eCut the ducting to the required length using scissors or a utility knife.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"18jw5dm\" data-start=\"2154\" data-end=\"2207\"\u003e\n\u003cp data-start=\"2157\" data-end=\"2207\"\u003eSlide the ducting over the fan or filter flange.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"oqgcyg\" data-start=\"2208\" data-end=\"2288\"\u003e\n\u003cp data-start=\"2211\" data-end=\"2288\"\u003eSecure in place using duct clips or strong tape to ensure an airtight seal.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"1hhxjxl\" data-start=\"2289\" data-end=\"2375\"\u003e\n\u003cp data-start=\"2292\" data-end=\"2375\"\u003eRoute the ducting through your grow tent ports or grow room ventilation openings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-section-id=\"hlpv11\" data-start=\"2376\" data-end=\"2459\" data-is-last-node=\"\"\u003e\n\u003cp data-start=\"2379\" data-end=\"2459\" data-is-last-node=\"\"\u003eAvoid sharp bends where possible to maintain maximum airflow through the system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/article\u003e\n\u003c\/div\u003e","brand":"Hydro Crop Shop","offers":[{"title":"5m \/ 4\"","offer_id":52712164950282,"sku":null,"price":7.5,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 5\"","offer_id":52712164983050,"sku":null,"price":8.5,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 6\"","offer_id":52712165015818,"sku":null,"price":10.0,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 8\"","offer_id":52712165048586,"sku":null,"price":13.0,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 10\"","offer_id":52712165081354,"sku":null,"price":15.5,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 12\"","offer_id":52712165114122,"sku":null,"price":19.0,"currency_code":"GBP","in_stock":true},{"title":"5m \/ 14\"","offer_id":52712165146890,"sku":null,"price":27.0,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 4\"","offer_id":52712165179658,"sku":null,"price":12.5,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 5\"","offer_id":52712165212426,"sku":null,"price":15.6,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 6\"","offer_id":52712165245194,"sku":null,"price":18.6,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 8\"","offer_id":52712165277962,"sku":null,"price":25.0,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 10\"","offer_id":52712165310730,"sku":null,"price":29.0,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 12\"","offer_id":52712165343498,"sku":null,"price":36.0,"currency_code":"GBP","in_stock":true},{"title":"10m \/ 14\"","offer_id":52712165376266,"sku":null,"price":47.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/ducting-combi-ducting-29227386208440.webp?v=1773486972","url":"https:\/\/hydrocropshop.co.uk\/products\/black-combi-ducting","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
