Everyone is concerned about keeping the temperature stable in the winter when they consider year-round horticulture in a greenhouse. What they should be concerned about in the summer is cooling the greenhouse.
When the temperature starts to climb, your plants within the greenhouse may suffer severely. This is why it is important to understand how to keep your greenhouse cold so that you can grow healthy plants even in the heat.
There are various strategies to keep your greenhouse cool throughout the summer, particularly if you live in a hotter climate. You may need to use some do-it-yourself techniques such as active ventilation or adding accessories such as swamp coolers and misters. The strategy you'll employ is determined by your available budget and the amount of cooling you need. Here are some ideas for keeping your greenhouse cool in the summer.
Ample ventilation
Making ensuring your greenhouse has proper ventilation is one of the most critical things you can do to control temperature and humidity. This will enable air to flow and maintain your plants' surroundings fresh and healthy. Roof vents, side vents, and automatic vent openers are all viable solutions.
It is critical to have enough vents to provide appropriate air circulation, regardless of the style of vent you pick. A general rule of thumb is to have one square foot of vent space for every 100 square feet of greenhouse floor space.
Utilization of Fans
Installing fans can be a huge help in promoting air circulation and distributing cold air throughout the greenhouse, which will ultimately result in a reduction in temperature. This is of the utmost importance during the warmer months, when the greenhouse may quickly become stuffy and unpleasant for both you and your plants. If you want to get the most out of the fans, be sure to position them strategically around the greenhouse.
There is a wide selection of fans available, including those that are fixed to the ceiling or the wall, as well as those that are placed on the floor. Fans that are fixed to the walls are the better choice for ventilation in smaller greenhouses, while ceiling fans are a good choice for larger greenhouses with high ceilings. Floor fans are very portable and may be relocated to deliver cooling exactly where it is required the most.
Shade Cloth
Shade cloth can help to limit the quantity of heat and light entering the greenhouse. This may help keep the temperature stable and prevent plant stress, particularly in hot weather. Shade fabric over the top and sides of your greenhouse may considerably decrease the inside temperature and offer a cooler, more pleasant habitat for your plants.
Shade cloth is available in a variety of densities ranging from 30% to 70%. The dense the shade fabric, the less light and heat penetrate the greenhouse. The density of the shade cloth may be chosen depending on the sort of plants you're cultivating and the environment in your location.
Misting and Watering
It is especially vital to water and spray your plants as well as the floor of the greenhouse when the weather is very hot. This will help bring the temperature down and enhance the humidity levels. This will assist in maintaining a cool and pleasant climate for your plants, and it will also give a supply of the moisture that is necessary for their growth.
You may choose to water your plants the traditional way, using a watering can or hose, or you can choose to install an autonomous watering system, which will make the procedure simpler and more effective. There is also the option of installing misting devices, which will spray a fine mist of water over the plants and the floor of the greenhouse.
Cooling through Evaporation
The temperature within the greenhouse may be controlled using an evaporative cooling system. This method works by moving air over water, lowering air temperature, and increasing humidity. Evaporative cooling systems are extremely useful in hot, dry areas, where they may help your plants flourish in a pleasant and healthy atmosphere.
Evaporative cooling systems, which normally consist of a fan, a water pump, and a cooling pad, are often positioned near the greenhouse's roof. The fan pulls hot air from the greenhouse and directs it through the wet cooling pad. The air cools as it travels over the wet pad, while the moisture from the pad adds humidity to the air. The cooled and humidified air is then cycled back into the greenhouse, decreasing the temperature and making your plants more comfortable.
Monitoring and upkeep
It is essential that you keep a close eye on the temperature and humidity levels inside your greenhouse in order to guarantee that your plants are flourishing in ideal conditions. You may get accurate readings of temperature and humidity by using separate instruments called thermometers and hygrometers. Always be sure to keep a close eye on the temperature and humidity levels in the room and make any necessary adjustments to the ventilation and cooling systems.
It is also essential to do routine maintenance on your ventilation and cooling systems if you want to guarantee that they are operating correctly. This may involve cleaning the vents and fans, replacing the filters, and making sure the water pump and cooling pad are operating as they should. Maintaining a high degree of system upkeep will assist in guaranteeing that your greenhouse maintains the temperature and humidity levels that are optimal for the plants you are growing inside.
Conclusion
Greenhouse ventilation and cooling are key components of ensuring your plants thrive in their growth environment. By following the tips in this article, you can keep your greenhouse at the appropriate temperature and humidity levels, resulting in healthy and strong development.
