Ventilation System with Automatic Valve (60mm)

Grow Kit Ventilation System with Automatic Valve (60mm Fan) This grow kit ventilation system is designed to provide efficient air exchange inside your grow container while minimizing the risk of contamination. The built-in valve is not manually adjustable. It automatically opens when a 60mm fan is running and closes when the fan is turned off. This prevents unwanted airflow, dust, or contaminants from entering the grow kit when the ventilation system is inactive. Features: Designed for 60mm fan Automatic flap valve (opens with airflow, closes when fan stops) Helps maintain proper fresh air exchange (FAE) Reduces risk of contamination when fan is off Compact and easy-to-install design Ideal for mushroom grow kits and other small controlled-environment cultivation setups.
