Build a Complete Grow Room Ventilation System — Fans, Ducting, Filters & Controllers
Airflow is the one thing you can't cut corners on. Heat stress, humidity spikes, stale CO₂, and escaping odours all come back to ventilation. This collection covers every component of a complete grow room airflow system — from the fan that moves the air, to the ducting that carries it, the filter that cleans it, and the controller that automates it all.
Inline Fans — Headwind HVC EC Mixed Flow Series
EC motor technology means high airflow with low power draw and near-silent operation. The Headwind HVC range is the backbone of any serious grow room ventilation setup.

Smart EC Fan Controllers — Headwind HVC
Plug directly into any HVC EC fan and automate your entire climate — no extra adapters, no guesswork. Manage up to 4 fans simultaneously.
