The BloomLED Combi Alu/PVC duct in Ø200mm is the essential conduit for moving air between your extractor fan, your carbon filter and the outside of your tent. Its multi-layer aluminium and PVC build limits heat loss and traps odours, keeping your indoor grow discreet and perfectly ventilated. Flexible, lightweight and compressible, it installs in minutes even in the tightest setups.

The Ø200mm diameter delivers generous airflow and limits pressure drop between fan and carbon filter.
The multi-layer wall dampens air noise and traps odours for a truly discreet indoor grow.
Flexible and compressible, it bends around corners and clamps into place in seconds with a Ø200 collar.
Pair it with a 200mm extractor fan and a matching carbon filter to keep full airflow and ventilation efficiency.
Is the 3m length expandable?Yes — it compresses for transport and extends up to 3 metres. Avoid tight bends to preserve airflow.
Correctly sized ventilation is the key to a healthy climate: controlled temperature, managed humidity and neutralised odours.
