A greenhouse allows you to control the temperature and ventilation in an enclosed space, which is essential to have healthy plants. Here are some tips to help you regulate the environment in your greenhouse.

Regulating the Temperature in Your Greenhouse

The amount of light will affect the temperature in your greenhouse. Summer crops grow best when the temperature is between 75 and 85 degrees during the day and less than 75 at night. During the winter, the temperature should not be more than 65 degrees during the day and can get down to 45 degrees at night.

Check the temperature requirements of the plants you want to grow in your greenhouse. If you want to grow plants in a greenhouse in the winter, you may need an auxiliary heat source. The cold outdoor temperatures can make it difficult to keep a greenhouse warm, even if it gets a lot of sun. Several types of greenhouse heaters are available, including propane and electric.

In other cases, you may need to cool your greenhouse to avoid overheating your plants. A greenhouse in a sunny area can get too hot, even in the winter. If your greenhouse is attached to your house, you may be able to move the warm air to your home.

How to Promote Air Circulation in a Greenhouse

Good air circulation is necessary to grow healthy plants in your greenhouse. Air circulation strengthens the woody tissue in plant stems and makes it harder for fungi to attack plants. Leave spaces between plants so they are not touching each other to allow air to circulate.

Plants need carbon dioxide in air to produce sugars for food. Carbon dioxide can be depleted in a closed greenhouse. Change the air supply at least once a day, even if that means you will need to add extra heat.

An easy way to increase air circulation in your greenhouse is to install screened windows and doors. You can open a window on one side and a door panel on the opposite end to create cross-ventilation. Warm air can rise and exit through high windows, and colder air can enter through lower windows.

If you have a free-standing greenhouse, you can use passive vents and thermostatically-controlled exhaust fans and intake vents. Manually-operated vents are inexpensive but need to be checked at least twice a day and opened or closed. An automatic ventilation system is more expensive but can save time and do a better job of regulating the temperature.
