Ventilation Ducting
The correct diameter and type of flexible ducting determine the final quality of air extraction from the grow tent. Remember that the ducting must be compatible with the fan and the carbon filter. You can choose from classic ALU flexible ducting, the more durable COMBI flexible ducting, silenced SONO flexible ducting and PhonicTrap ducting, which is rigid and almost completely silent. At the bottom of the page you will find a practical overview of pack sizes and dimensions.
Choose carefully and do not hesitate to ask us for advice, just write to info@higarden.cz.

The correct diameter and type of flexible ducting determine the final quality of air extraction from the grow tent. Remember that the ducting must be compatible with the fan and the carbon filter.
And how do you easily find your way around these ducts?
- The first thing is to choose the correct size. If your fan has a 100 mm flange, a 100 mm hose will match it too (it is actually slightly larger so it can be fitted on)
- Ideally, the fan and filter should have the same flange, but if they differ, it does not necessarily have to be a problem - just use a reducer. However, make sure the ducting does not narrow after the fan, or that the fan has sufficient power reserve and can push enough air through the narrower ducting. If narrowing is unavoidable, it should never be more than one size, for example from 200 mm to 160 mm or from 125 mm to 100 mm.
- Basic ducting with a single-layer outer shell made of aluminium and plastic is ALU flexible ducting. The cheapest option for grow boxes allows reliable and flexible air routing. This ducting is suitable for temperatures up to 60 °C.
- ALU flexible ducting wrapped in black plastic for greater mechanical resistance and therefore longer service life – that is COMBI.
- SONO is flexible ducting with sound insulation and an approximately 30% larger hose diameter. This difference lies precisely in the presence of the insulating layer.
- If you need to reduce noise as much as possible, we recommend PhonicTrap ducting, which reliably dampens sound and ensures discreet operation. The acoustic insulation of the ducting is twice as effective as SONO and does not shed pieces of glass wool. Because of the insulation, it is slightly thicker than usual.
Tip: If you are dealing with noise, we recommend using SONO together with noise dampers on the fan.
Choose ducting according to diameter and requirements for strength or sound insulation. It is available in packs of 3 m, 6 m and 10 m.

For air distribution, you also need accessories for ducting, namely the absolutely essential clamps and connectors, Y pieces (Y joints), T pieces, as well as end caps or practical insect screens, which protect your growing space from pests and more.
TIP: If something goes wrong in the grow room, silver adhesive tape will definitely come in handy, as it quickly solves a minor problem and does not reduce the reflectivity in the room much.
