Vortex Black Combi-Ducting in 10 Metre Lengths

Combi-Ducting is used to as part of your ventilation system to move air to and from the grow area, replenishing CO2 and removing excess heat and humidity. Combi-Ducting has a double-layered construction with an aluminium inner and a plastic outer, greatly increasing its resistance to tearing while also preventing light leaks.

How Vortex Black Combi-Ducting works

With both an internal aluminium sheath and a layer of plastic around the outside, combi-ducting is much more resistant to tearing than standard aluminium flexi ducting, as well as being fully lightproof.

Combi-ducting is generally used to carry air from your extractor fan/filter to an outlet nearby. It can also be used to carry fresh air into your grow-space from an inlet. It can easily be shaped around corners and will concertina down to a very short length if needed.

How To Use

How to Use Combi-Ducting

Combi-ducting fits directly over the flange of your same-diameter extractor fan or filter and an appropriately sized duct clip is usually used to hold it tightly in place. The ducting can then be run to your air outlet/inlet. Although Combi-Ducting works fine when run loose, the noise from air-flow through the ducting will be greatly reduced if it is stretched out as much as possible. To reduce Combi-Ducting down to the correct length, use a sharp pair of scissors to cut the aluminium and a pair of sharp wire cutters to snip the spiral wire in the appropriate place.
