Heating and Ventilation
Greenhouses harness the sun's rays to heat the interior air. All greenhouses must include proper ventilation to achieve the ideal greenhouse temperature, either side vents and fans that manage the hot air and cool air or top vent that opens a hatch in the ceiling. Some greenhouses' features can offer to operate the greenhouse manually or automatically.
The manual ventilation feature is cheaper. Remember that you must open and shut the vents or open the door during the day and close it at night. Some people may consider this hassle for those who aren't home during the day, and this is also a problem if the weather changes suddenly.
The automatic ventilation system has a sensor that turns on the fans or heating if the temperature rises or falls below thresholds on the system's program.
The following are the tips to ensure the ideal greenhouse temperature:
- Make sure to open the door on warm days. Put heavy rocks in front of the door if needed to prevent the door from shutting from the wind.
- Use additional stand fans to keep the air moving if needed.
- Open the lid of the cold frame to allow air to circulate during the day.
Tips to Decrease Greenhouse Temperature
You must invest your time and money to build and maintain your greenhouse. It provides a controlled environment for your plant's growth in your garden. Greenhouse offers shelter for your plants during rainy, sunny, and windy season. Every summer, the level of heat temperature inside your greenhouse is challenging to handle. During the cold season, your greenhouse temperature will increase, and that is the most challenging case to handle. These tips will help you to decrease the heat or cold level in your greenhouse:
Natural Ventilation
Natural ventilation will help you decrease the temperature level in an overheated greenhouse. Open all windows and doors to allow hot air to escape from your greenhouse. If the budget is not a problem in your case, you have an option to put a hinged roof that you can open during high temperatures to avoid the accumulation of hot air.
Ventilate Using Shade
Using shade to ventilate the greenhouse helps in reducing heat temperature. There are various types of greenhouse shade, such as compound shading, liquid shading, and leady vines growing at the top of the greenhouse.
Fan Ventilation
Fan Ventilation helps you push the hot air out and makes the air cooler. The proper location of fans is essential. Do not put the fans at the ground level or the top of the roof. Allot at least five to six feet away in front to draw the air over and through the plants. Put the wet pad into the fans to give an evaporative cooling effect and to avoid the plants to dry.
