Plants can be grown outdoors in areas with warm weather. In regions where there is cold weather and seasonal restrictions, the growth of plants in that environment faces problems that disrupt their growth. To avoid this problem of heating and cooling, we refer to the knowledge of greenhouses and plant breeding centers.
Types of greenhouse equipment
Heating systems
Greenhouse ventilation system
One of the most essential greenhouse equipment is the greenhouse ventilation system. Good ventilation is critical to maintaining an optimal growing environment and improves overall greenhouse efficiency. Also, good temperature and humidity management is essential. Ventilation is important for air circulation and carbon dioxide replenishment. Poor air circulation reduces plant activity and can lead to problems in humidity and disease management.
Air movement in the greenhouse should be between 0.2 and 0.7 meters per second. If the level of carbon dioxide is not maintained, plant growth will be affected. This is a greenhouse equipment related to air exchange. A large volume of air must be moved in hot conditions. A greenhouse should be able to do at least 30 air changes per hour, but ideally 60 air changes per hour to ensure that the greenhouse environment can be managed. Ventilation can be done passively or actively. The ventilation capacity of greenhouses is usually described as a percentage of the ground surface. For example, a greenhouse with 30% roof ventilation has 0.3 square meters of open air space for every 1 square meter of ground surface. Greenhouse equipment should have at least 25% ventilation capacity, but up to 40% is desirable. It is better if the ventilation capacity is more than needed.
Greenhouse valves
Passive ventilation uses vents that naturally draw air through the greenhouse. Ventilators are the most common method of ventilation used in greenhouse production. Ceiling ventilation is a more effective method of air exchange than side wall ventilation. Although different designs of greenhouse equipment vary in effectiveness, in general, roof vents are up to 5 times more effective than side wall vents.
Greenhouse fan
Active ventilation is the use of equipment that brings air into or out of the structure. Fans are the key method for active greenhouse ventilation. Fans can also be installed in greenhouses to move the air inside the greenhouse. Circulating fans are often used in passively ventilated structures to help move air when ventilation is minimal. When using fans for air exchange, the most effective method is to draw air along the entire length of the greenhouse structure and equipment to avoid remaining hot air pockets. The fans that are placed to remove the air from the higher parts of the greenhouse are more effective for cooling than the fans that are placed at the bottom.
Light control devices
Lighting systems can be automatically triggered using simple timers or complex integrated controllers. Some greenhouses with large installations may not have enough electrical service to run all of their lights at once; Therefore, they may need to be adjusted according to the available electrical power.
The best thermometer and moisture gauge
The greenhouse thermometer is one of the most essential equipments of the greenhouse. Monitoring temperature changes in the greenhouse is very important to help crops grow. During the summer, the greenhouse should not be overheated, and during the winter, the plants should be protected from the cold. The ideal temperature for a greenhouse depends on the crops being grown. Temperature may be the first factor to check, but humidity is a close second. is Knowing the amount of water vapor in the air is very important; Because some plants need a more or less humid environment for optimal growth. Fortunately, both of these are easy to measure. All you need is a digital greenhouse thermometer and hygrometer.
Greenhouse digital digital humidity
Among the greenhouse equipment, these items are also very important. When you want to monitor the initial greenhouse temperature, it is recommended to buy a wireless digital thermometer. This greenhouse thermometer shows the minimum and maximum temperature for a specific time period (usually 24 hours) and allows you to closely monitor the temperature inside the greenhouse. Depending on your climate, there is a big difference between a sunny day And there is a cold summer night; This is why a good insight into the highest and lowest temperatures is essential. While you can choose a traditional and analog model among greenhouse equipment, it is suggested to go for a more advanced digital thermometer.
Fog Cooling System
This system is considered one of the methods of cooling the greenhouse and minimizes the ambient temperature, which in the summer season reduces the temperature inside the greenhouse and around the flowers and plants. The main function of this system is to produce moisture and mist and water particles in the smallest form, which prevents getting wet and increasing the disease and the effects of salt and salts in plants that remain on the surface of the plant. Evaporated drops of water should be released at a specified height above the plants in the plant breeding hall. Evaporated drops will lower the temperature of the greenhouse before hitting the plants. In areas where the intensity of the sun's heat is high, using a mist cooling system can be the most effective way to reduce the temperature. If the design of the fogger is done correctly, it can create the ideal temperature and humidity for the greenhouse space so that the plants can grow sufficiently in the environment.
