Black Combi Ducting is a cost effective solution for grow room ventilation.
Purposely designed in black to prevent light reflection through the ducting, it has a double layered construction with an aluminium inner and a plastic outer, greatly increasing its resistance to tearing while also preventing light leaks.
- Dual layered construction – aluminium sheath with polyester outer
- Greater resistance to tearing than standard aluminium ducting
- Reduced noise levels compared with single layered ducting
- Prevents light leaks
- Available in 5 and 10 metre lengths, from 4 to 14 inches
