Greenhouse

Overview
Greenhouses are structures designed to provide ideal growing conditions for plants. These structures are usually made of glass or plastic and are used to create a controlled environment for growing crops, plants etc. However, maintaining the ideal environment inside a greenhouse can be challenging, especially during the hot summer months. Proper greenhouse ventilation is essential for the success of any greenhouse operation. On this website, you will see different types of greenhouse ventilation products, and best practices for greenhouse ventilation. Greenhouses give us the opportunity to grow year round by harnessing the power of the sun and eliminating the negative effects of inclement weather, pests and disease and allows controlled pollination. There are basically two kinds of ventilation. Natural or passive ventilation can be achieved through strategically placed vents and inlets and rely on wind or natural occurrences to work. And, there is an active ventilation or mechanical ventilation systems which is the most reliable and preferred method for large scale operation but require a power supply. Mechanical and Passive or Natural ventilation products are what you will find available on this web page. There is one more strategy worth noting and that is Hybrid Ventilation. Hybrid ventilation is a combination of natural ventilation and mechanical ventilation. It involves using both natural and mechanical ventilation systems to regulate the temperature and humidity inside the greenhouse. Hybrid ventilation is ideal for medium-sized greenhouses.

Importance of Greenhouse Ventilation
Greenhouse ventilation is essential for maintaining a healthy growing environment for plants. It allows for the exchange of air, which helps to regulate the temperature, humidity, and carbon dioxide (CO2) levels inside the greenhouse. Without proper ventilation, the temperature inside the greenhouse can quickly rise, leading to heat stress and plant damage. Similarly, high humidity levels can cause fungal diseases to develop, while low humidity levels can cause plant dehydration. Carbon dioxide is also crucial for plant growth, and proper ventilation ensures that there is enough CO2 for the plants to perform photosynthesis.

Greenhouse Exhaust Fans
Proper greenhouse ventilation is essential in creating the ideal environment for your growth cycle and creating more profitable blooms. Since plants can breath out or transpire up to 80% of the moisture they take in through their roots, its critical to remove excessive heat and humidity from your greenhouse. Greenhouse exhaust fans are an excellent way to keep your growth environment maximized by maintaining a negative pressure to remove unwanted humidity and excessive heat while pulling in fresh air and much needed carbon dioxide through a motorized shutter or louver system. Typically you want the greenhouse exhaust fans to be as far away from your fresh air supply inlets as possible. You can mange the climate and automate the system through thermostats, humidistats or timers depending on your geographical location and the type of plants or produce your growing. Before designing your greenhouse ventilation system, know your climate and the climate required to maximize your plants growth potential.

Greenhouse Recirculation Fans
Recirculation fans are another important part of your greenhouse ventilation system. Horizontal Air Flow (HAF) Fans can be used to create a circular air flow pattern in your greenhouse removing any unwanted air pockets and ensuring your greenhouse is properly breathing. Airdistributor carries a complete line of fixed mount circulation and basket fans, panel fans and portable circulation fans to keep the air moving through your greenhouse.

Best Practices for Green House Ventilation
Proper greenhouse ventilation requires careful planning and execution. Here are some best practices for greenhouse ventilation:

• Determine the ventilation requirements based on the size of the greenhouse, the type of crops being grown, and the climate in the area.
• Use a combination of natural and mechanical ventilation systems to achieve optimal results.
• Install intake vents low to the ground and exhaust fans high up in the greenhouse to create a natural flow of air.
• Use temperature sensors to monitor the conditions inside the greenhouse and adjust the ventilation accordingly.
• Clean the ventilation systems regularly to prevent the buildup of dust and debris, which can reduce the efficiency of the system.
• Use shading and insulation to reduce heat buildup inside the greenhouse, which can reduce the need for excessive ventilation.
• Consider using automated greenhouse ventilation systems that can adjust the ventilation based on the conditions inside the greenhouse.
