An essential part of any self-respecting hydroponic grow room, Combi ducting is the ultimate solution for a cheap, yet tough and durable method of ventilating air through either an extraction or intake system.

Similar in ease of use to the single sheathed aluminium ducting, however one key selling point of the combi ducting is that of its plastic outer layer. This extra layer ensures that it remains almost impossible to tear or perforate when installing it. This avoids any issues that may arise with either light leakages through the ventilation, or any unfiltered grow-room air making its way to the outside world.


Try to cut the ducting to just the right length, to avoid any unwanted sagging and consequently drop in air flow rates. Simply pierce the aluminium sheath with a sharp knife where needed and use wire cutters/pliers to cut through the wire skeleton.

Check the connection is air tight by running a lit splint around the connections. Any smoke will be drawn into areas not correctly sealed, indicating further attention is needed to secure this area.

Use in combination with elbow’s and Y pieces to ensure minimal drop in air flow around corners.
