One of the issues to be concerned about when using greenhouses is the circulation and control of the air. </span><span style="font-weight: 400; font-family: arial, helvetica, sans-serif;">Let’s learn more about air circulation for greenhouses in the article below.</span></p> <figure id="attachment_1281" aria-describedby="caption-attachment-1281" style="width: 640px" class="wp-caption aligncenter"><img fetchpriority="high" decoding="async" class="wp-image-1281 size-full" title="Types of ventilation, notes and exhaust fans for greenhouses" src="https://systemfanglobal.com/wp-content/uploads/2022/11/exhaust-fan-for-greenhouses.jpg" alt="Types of ventilation, notes and exhaust fan series for greenhouses" width="640" height="447" srcset="https://systemfanglobal.com/wp-content/uploads/2022/11/exhaust-fan-for-greenhouses.jpg 640w, https://systemfanglobal.com/wp-content/uploads/2022/11/exhaust-fan-for-greenhouses-300x210.jpg 300w, https://systemfanglobal.com/wp-content/uploads/2022/11/exhaust-fan-for-greenhouses-600x419.jpg 600w" sizes="(max-width: 640px) 100vw, 640px" /><figcaption id="caption-attachment-1281" class="wp-caption-text">Types of ventilation, notes and exhaust fans for greenhouses</figcaption></figure> <h2 style="text-align: justify;"><span class="ez-toc-section" id="Benefits_of_greenhouse_ventilation_for_cultivation"></span><span style="font-family: arial, helvetica, sans-serif; color: #339966;"><b>Benefits of greenhouse ventilation for cultivation</b></span><span class="ez-toc-section-end"></span></h2> <h3 style="text-align: justify;"><span class="ez-toc-section" id="Greenhouse_temperature_control"></span><span style="font-family: arial, helvetica, sans-serif; color: #339966;"><b>Greenhouse temperature control</b></span><span class="ez-toc-section-end"></span></h3> <p style="text-align: justify;"><span style="font-weight: 400; font-family: arial, helvetica, sans-serif;">The temperature in the greenhouse directly affects the quality of the crop. A line of plants will have different suitable temperatures for their growth. Normally, the space temperature outside the greenhouse often deviates from the temperature required for the plants. In addition, during respiration and photosynthesis, plants also produce a certain amount of heat.</span></p> <p style="text-align: justify;"><span style="font-weight: 400; font-family: arial, helvetica, sans-serif;">To ensure the proper temperature is maintained in the greenhouse, it is common to use ventilation measures for the greenhouse.</span></p> <h3 style="text-align: justify;"><span class="ez-toc-section" id="Eliminate_gas_stratification"></span><span style="font-family: arial, helvetica, sans-serif; color: #339966;"><b>Eliminate gas stratification</b></span><span class="ez-toc-section-end"></span></h3> <p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif;"><span style="font-weight: 400;">Each type of gas has a different mass, the heavy gases are usually located at the bottom, and the light gases will rise to the top. This results in gas stratification. Plants may not receive the same beneficial gases. </span><span style="font-weight: 400;">With greenhouse ventilation fans can help prevent air stratification, they help diffuse air evenly throughout the greenhouse. Thus, promoting the best growth for plants.</span></span></p> <h3 style="text-align: justify;"><span class="ez-toc-section" id="Moisture_balance"></span><span style="font-family: arial, helvetica, sans-serif; color: #339966;"><b>Moisture balance</b></span><span class="ez-toc-section-end"></span></h3> <p style="text-align: justify;"><span style="font-weight: 400; font-family: arial, helvetica, sans-serif;">Greenhouses often create a large amount of humidity, in which some plants need less moisture such as orchids.
