The success of a greenhouse is not just in its ability to trap and retain heat. A proper greenhouse should also have proper ventilation that reduces stifling heat and most plant diseases. Before you buy a greenhouse, consider equipping it with an exhaust fan in order to improve its ventilation capabilities.
Why An Exhaust Fan?
An exhaust fan ensures the growing environment for the plants is optimum. It regulates the internal temperatures by doing away with excess humidity, stale air, and heat, all while drawing fresh and cool air from without. The temperature interchange process helps in the following:
- Temperature control: Although you want to do everything to retain heat, excess of it will tamper with the plants’ growth. An exhaust fan helps maintain just the right ranges by lowering the internal temperatures to the right levels.
- Humidity management: Plants regularly release moisture through the process of transpiration, increasing the amount of humidity inside the greenhouse. Excess moisture has adverse effects, such as fungal leaf rot, mold, and mildew. An exhaust fan will assist in reducing these risks.
- Proper air circulation: proper air circulation translates to healthier plants. It ensures the appropriate movement of carbon (II) oxide, which is necessary for photosynthesis. Additionally, it prevents any formation of any stagnant air inside the greenhouse.
- Disease reduction: it is difficult to attract many pests in a well-ventilated environment. An exhaust fan ensures that the greenhouse environment is always refreshed.
Signs You Need An Exhaust Fan
It is paramount to know the exact moment your greenhouse requires an exhaust fan. Be observant of the following key signs in order to respond accordingly:
High Levels Of humidity
You recognize the presence of excess humidity through foggy windows and damp interiors. An exhaust fan will fix that by providing the right moisture balance inside your warehouse.
Overheating
There are times when the temperatures will soar, especially during warmer seasons. Excess heat could kill your plants if not managed. An exhaust fan will provide a convenient environment for growth.
Stagnant Air
If you recognize there is stale air or there is inconsistent plant growth, take that as an indication there is insufficient air circulation. An exhaust fan will ignite air movements, facilitating proper air movement inside the greenhouse.
Rampant Pest Infestations
Pests and diseases thrive in places of high humidity and stale air. The presence of a disease outbreak is a wake-up call for better ventilation. An exhaust fan will facilitate a better plant environment.
More Condensation Buildup
Excess condensation, especially on the walls of the greenhouse, is a breeding space for diseases. An exhaust fan pushes the moist air out of the greenhouse, reducing condensation.
Uncontrollable Climate
The main reason you buy greenhouse is to try to have some control over the temperatures necessary for your plant growth. However, the outside climate is uncontrollable, and you will find yourself trying to get the balance between the temperatures inside the greenhouse and from without. An exhaust fan will aid in proper air regulation as well as circulation.
Exhaust Fan Maintenance
It turns out that an exhaust fan is paramount in a greenhouse project. The right quality is also pricy to acquire, especially if your plant space is large.
Often clean your exhaust fan to ensure that it is always performing optimally. Apart from cleaning, ensure you also do the following:
- Lubrication: Always apply the right lubricators on the motor and any other moving parts. If the fan is not self-lubricating, ensure you lubricate after every nine to ten months. Use a manufacturer-approved lubricator to avoid any unwanted complications.
- Regular checks: Regularly inspect the fan’s blades for any damage, wear, or tear. Sometimes there will be some bent blades. You will have to replace them immediately.
- Motor maintenance: Inspect your fan for any overheating. You will notice this through burning smells or slow operations. Do not obstruct the ventillations.
- Thermostats tests: Constantly check the thermostats or any automated system. The thermostat readings will help you check and verify the system’s temperature. Adjust the thermostat’s settings as required.
- Rust prevention: Identify corrosions early and do away with any rust. Ensure that any rust or corrosion is identified early, especially if you live in very humid areas.
Conclusion
The right exhaust fan will ensure that your greenhouse is well-ventilated. Proper ventilation will reduce the risks of diseases as well as improve the plants’ yield.
