Exhaust fans for greenhouse – The Importance of Greenhouse Ventilation & temperature
Ventilation is essential for balancing an indoor climate that makes the most of the powerful solar spectrum, while keeping an optimal temperature and air quality to help your plants thrive! Good ventilation is essential for both good temperature and humidity management of a greenhouse. Poor air circulation reduces plant activity and can lead to problems with humidity and disease management. Ventilation is important for air circulation and replenishing carbon dioxide. If carbon dioxide levels are not maintained, plant growth is affected.
Greenhouse temperature control is important to keep plants growing even during the offseason. The perfect temperature for a greenhouse is 27°C. Most plants and vegetables will grow healthy under this temperature. But in the hot area, it is most commonly achieved using passive roof ventilation— hot air up and out of the roof vents, pulls in cooler air. Greenhouses will be extra hot during the summer, temperature and humidity control during the summer require a canny combination of ventilation, humidity and shade. Obviously, that’s not a smart solution!
It is better to have more venting and temperature controlling capacity than you need. Equipping exhaust fans for greenhouses and evaporative cooling pads is a good step.
Key Method Of Actively Venting and Cooling A Greenhouse
However you use your greenhouse, it’s important to understand the benefits of an efficient and economic greenhouse ventilation / cooling system.
Greenhouse Ventilation Tip #1 – Airflow is Essential
Airflow affects a multitude of aspects of your greenhouse. Temperature control, improved air circulation, humidity control and carbon dioxide/oxygen replacement are essential parts of keeping the greenhouse climate viable for healthy plants. SINOGREEN offers active ventilation systems to quickly exchange large volumes of air. Ventilation fans generally need to have sufficient capacity to completely replace the air in the greenhouse every minute. Different sizes of greenhouses need different capacities of ventilation fans. So, check out the best exhaust fans for greenhouses to help get a leg up on airflow in yours too!
Greenhouse Ventilation Tip #2 -Temperature Control is Key
We probably built our greenhouse in order to keep plants warm, but without proper ventilation, pretty much every greenhouse will get too hot, even in relatively cool weather. Many plants will wilt and die if the greenhouse temperature isn’t controlled.
Greenhouse without cooling systems will typically be at least 10-20°F warmer than the outside temperature, especially in hotter climates and in summer months.
Please keep in mind that the variety of plants we are growing will determine what our greenhouse climate needs to be, and that might vary greatly. It’s also worth noting that the size of your greenhouse will affect the resources it takes to cool it.
