Vortex Aluminium Ducting - Flexible Duct for Extraction and Intake
Best for: growers running an extraction or intake setup who need flexible, heat-tolerant ducting between fan, filter and tent.
Our thoughts
This is bread-and-butter grow room kit, the sort of thing that does not get much thought until you realise your intake or extraction run needs another length. Aluminium ducting like this holds its shape far better than the thin plastic stuff, and the steel helix means it will not collapse the moment you bend it round a corner. Not exciting, but exactly what most tents actually need.
Vortex Aluminium Ducting is a flexible duct built from polyester-laminated aluminium foil wrapped around a high tensile steel wire helix. The helix gives the duct its shape and crush resistance, letting it hold a bend without collapsing or pinching off airflow, while the laminated aluminium layer is what makes it noticeably more heat-tolerant and durable than basic plastic ducting.
It comes in a choice of diameters to match different fan and filter sizes, and in two length options so you can pick a shorter run for a compact tent or a longer length if your fan and filter are further apart. Being flexible, it can be stretched, compressed or bent around obstacles, then cut to length with scissors or a sharp knife if you need an exact fit.
How it compares
Ducting is one of those categories where the material and construction matter more than the brand name on the box.
- Compared with thin plastic ducting, aluminium ducting like this is far more heat-tolerant, so it holds up better running close to hot HID reflectors or lamp ballasts.
- Against rigid PVC or metal ducting, this flexible version is much easier to route around awkward tent frames and shelving, at the cost of being slightly less airtight if not clipped and taped properly at the joins.
- Similar aluminium flexi-ducting from more premium extraction brands costs more but offers broadly the same core construction: laminated foil over a steel helix.
It is a solid, no-nonsense choice if you want ducting that will hold its shape and handle warm air without the price tag of premium branded extraction ducting.
Usage guidance
Getting a clean, efficient duct run is mostly about length, support and sealing the joins properly.
Sizing your run
Match the duct diameter to your fan and filter's spigot size, and choose the shorter or longer length option depending on the distance between your fan, filter and vent point. Long runs with lots of bends will reduce airflow, so keep the route as short and straight as practical.
Fitting
Stretch the duct out to its working length, secure it onto spigots with duct clips or good quality tape, and avoid sharp kinks that can restrict airflow.
Support
Support longer horizontal runs so the duct is not hanging under its own weight, which over time can pull joints loose or create sagging low points where condensation can collect.
Technical specifications
- Construction: Polyester-laminated aluminium foil over a high tensile steel wire helix
- Diameters: Choice of sizes to suit common fan and filter spigots
- Lengths: Two length options available
- Flexibility: Fully flexible, holds its shape when bent
- Heat tolerance: Higher heat tolerance than plastic ducting, suitable for use near HID reflectors
- Cutting: Can be cut to length with scissors or a sharp blade
- Typical use: Intake and extraction runs in grow tents and rooms
Who this is for
- Growers setting up intake or extraction on a new tent or room
- Anyone replacing collapsed or damaged plastic ducting with something more durable
- Growers who need a specific length or diameter to fit an awkward space
- Budget-conscious growers who want solid ducting without paying premium extraction-brand prices
Our take
Ducting will not win you any grow-of-the-month awards, but a collapsed or kinked duct will absolutely tank your extraction and heat control. This gives you a durable, flexible option that holds its shape and shrugs off heat better than the cheap plastic stuff, at a price that makes sense.
Pick the length and diameter that matches your setup and get it fitted properly. Does exactly what it should, day in, day out.
