How to Choose the Right Greenhouse Ventilation Fan
Keeping your greenhouse climate under control is the key to thriving plants and it all starts with the right ventilation fan. Here's how to make the smart choice.
Some tips of how to choose the proper greenhouse ventilation fan
Know Your Size — And Don’t Overdo It
The most common mistake? Buying a fan that’s too powerful for your space. For proper airflow, your fan should exchange the full volume of air in your greenhouse every 5 minutes. That’s roughly 200 m³/h (cubic meters per hour) per 10 m² of floor space. Oversized fans create turbulence and can harm plants — so match fan power to your actual needs.
Types of Fans: Pick the Right One
- Axial fans. Best for small-to-medium greenhouses. Efficient, lightweight, and easy to mount.
- Centrifugal fans. Great for larger or high-humidity greenhouses. Quiet, with more controlled airflow.
- Channel fans. Ideal for high-output systems needing targeted airflow.
Climate Control Made Easy
Look for fans with built-in temperature and humidity sensors. These auto-activate based on climate shifts keeping your greenhouse consistent without constant manual checks.
Smart Placement = Better Airflow
- For small greenhouses, install fans at the front or back walls.
- For larger greenhouses, use side-mounted fans or roof installations, and supplement with internal circulation fans.
- Add a vent or intake window on the opposite side of the fan for cross-ventilation.
Seasonal Adjustments
- In winter, use closeable intake vents to maintain heat.
- In summer, hang a damp cloth over the intake to add humidity and cool the air.
Protect Your Investment
Use automatic shutter-blinds to protect your fan from outside dust, rain, or snow. These shutters close when the fan is off and extend its lifespan significantly.
Monitor with Thermometers
Place 2–3 thermometers in different areas of your greenhouse to track temperature zones and adjust your fan system as needed.
