Airflow, Ventilation & CO2
Ducting
Ducting refers to the tubing or channel system used to move air into, out of, or within a cannabis grow space. It connects ventilation components such as fans, filters, and exhaust systems.

What Is Ducting?
Ducting is a component of indoor cannabis ventilation systems designed to transport air between equipment and the grow environment. It directs airflow from intake sources to the canopy and from the grow space to exhaust outlets. Proper ducting ensures efficient air exchange and stable environmental control.
How Ducting Connects Ventilation Components
In most grow setups, ducting connects inline fans, carbon filters, and exhaust ports. When air is pulled through the system, ducting channels stale air away from plants and expels it outside the grow space. Intake ducting may also be used to bring fresh air into the room, supporting consistent CO₂ levels and temperature regulation.
How Duct Material and Size Affect Airflow
The material and diameter of ducting influence airflow efficiency. Flexible aluminum ducting is commonly used for its adaptability, while rigid ducting may provide smoother airflow with reduced resistance. Selecting appropriate duct diameter helps maintain proper static pressure and fan performance.
How Installation Impacts System Efficiency
Poorly installed ducting can restrict airflow and reduce ventilation effectiveness. Excessive bends, long runs, or crushed sections create resistance that forces fans to work harder and lowers overall air exchange rates. Minimizing sharp turns and keeping duct runs as short as practical improves system efficiency.
How Ducting Supports Odor Control
Ducting also plays a role in odor control. When connected to carbon filters, it ensures that exhausted air passes through filtration before leaving the grow space. Proper sealing of joints prevents leaks that could allow unfiltered air to escape.
Why Proper Ducting Maintains Environmental Stability
Effective ducting supports temperature stability, humidity control, and consistent airflow distribution. As part of a well-designed ventilation system, it helps maintain an optimal growing environment and protects overall plant health and yield potential.
