5m White Combi Ducting — Reflective Outer with Dual-Layer Construction

5m White Combi Ducting — Reflective Outer Cover with Dual-Layer Construction

Combi-Ducting moves air to and from the grow area as part of your ventilation system — replenishing CO₂ and removing excess heat and humidity. Dual-layer construction with aluminium inner and plastic outer greatly increases tear resistance while preventing light leaks. The white reflective outer cover reduces noise from airflow and reflects heat away from the duct.

Why growers choose 5m White Combi:

• 5m length — middle-ground for typical home grow-room layouts
• White reflective outer cover — reflects heat and light, reduces grow-room temperature gain
• Reduces airflow noise — outer cover dampens noise vs bare alloy ducting
• Dual-layer construction — proper tear resistance, professional build
• Aluminium inner for strength — holds shape under extract suction
• Plastic outer for flexibility — bends around corners and obstacles
• Universal compatibility — fits any matching diameter fan/filter

Who it's not for:

For darker grow rooms where reflectivity isn't needed, standard alloy combi at lower cost is adequate. For acoustic noise reduction (serious quiet operation), RAM Sonoduct or Phonic Trap deliver better noise control. Check the diameter matches your fan and filter — 4", 5", 6", 8" all have different variants. For longer runs, 10m is better value than multiple 5m sections.
