Black Combi Ducting

Black Combi Ducting is a premium ventilation hose designed for efficient, lightproof air movement in hydroponic grow rooms, tents, and greenhouses. Featuring a multi-layered construction—aluminium inner core with a tough black PVC outer layer—this ducting provides flexibility, strength, and superior resistance to tearing, temperature, and pressure. The black outer layer blocks light leakage, making it perfect for sealed environments where controlling the photoperiod is essential for plant development and flowering. This helps protect the root zone and canopy from environmental fluctuations, mould risk, and unwanted stress. Compatible with all standard ducting accessories, inline fans, and carbon filters, Black Combi Ducting is ideal for building robust intake or extraction systems in automated irrigation setups and professional grow operations.
