Exhaust fans for grow tents and grow cabinets
A good exhaust fan ensures continuous air circulation and helps to remove heat and moisture from your grow tent or grow cabinet. This allows you to better control the temperature and humidity and create a stable climate in which plants can grow optimally.
In this collection you will find fans for different sizes of grow spaces. From compact extractors for smaller setups to powerful EC fans for larger spaces. When choosing a fan, not only pay attention to the maximum capacity in m³/h, but also to the diameter of the air connection, noise production, energy consumption, and options for speed control.
Quiet and energy-efficient EC fans
For grow tents where noise production and energy consumption are important, modern EC exhaust fans offer clear advantages. An EC motor can work efficiently at various speeds, making it excellently suited for a ventilation system whose capacity needs to be regulated.
The Hortifan Silent fans combine an energy-efficient EC motor with PWM control. With a compatible fan controller, you can regulate the fan speed or, depending on the controller, have it automatically adjust to the temperature and humidity in the grow room.
What capacity do you need?
The required capacity of an exhaust fan is determined by more than just the volume of the grow tent or grow cabinet. The heat production of the lighting, ambient temperature, length of the air hose, and the use of a carbon filter also influence the required air displacement.
Please note that the stated capacity in m³/h generally indicates the maximum airflow of the fan. A connected carbon filter, air hose, and bends cause resistance, which means that the actual airflow in a complete ventilation system is lower.

A stable climate for your plants
A well-chosen fan helps to remove excess heat and moisture, but the correct settings depend on the plants and growth phase. Would you like to know more about this?
