How Do I Keep My Grow Tent Warm at Night?

There are a number of options available for heating your grow tent at night. These include electric heaters, fan heaters, and even ducting. Each one has its own advantages and disadvantages, so it’s important to consider your specific needs. If you are concerned about the amount of heat your grow tent receives during the night, here are some tips to help keep your plants comfortable.

Propane heaters

Propane heaters can keep your grow tent cozy during the night. These devices are effective in indoor and outdoor spaces. Propane heaters should have vents for fresh air to come in and carbon monoxide to escape. You should not let the heater run constantly, because this can be dangerous. Propane heaters for grow tents should be properly vented to prevent carbon monoxide buildup. Propane heaters should also have safety features such as low-oxygen sensors and tip-over safety features.

Propane heaters for grow tents are available with thermostats to control the temperature. They are designed to circulate heat quickly and evenly to keep your grow tent at a comfortable temperature. Many of these heaters feature dual temperature settings, and they are easy to control. These heaters also have a tip-over switch to prevent shock, and an overheat protection switch.

Electric heaters

An electric heater will keep your grow tent warm at night, and you can use a fan to help keep your plants from being too cold. You can also buy a humidifier and use it if your tent is very dry. You can also put wet towels inside the tent to add moisture. When you’re growing indoors, it is essential to have a proper air exchange. Fans will remove the hot air and bring in the cooler air. This change of air will help strengthen your plants.

The best grow tent heater is one with a thermostat, so you can control the temperature inside your tent. It should be able to control its temperature and shut off automatically when it reaches the right temperature. The best ones will have an adjustable timer so you can set it to come on for an hour, ten hours, or twelve hours.

Fan heaters

Fan heaters can be a great way to keep your grow tent warm at night. These units are very efficient at distributing warm air and are easy to control. You can set them to turn on when the temperature drops and shut them off when the temperature rises. They also have a thermostat, which helps you save power. Choosing the right heater for your tent can help you grow plants safely and successfully.

Depending on your needs, a fan heater can be either an electric or a gas heater. An electric heater will need an outlet and an extension cord. A heavy duty extension cord is recommended, as regular ones can catch fire if they overheat. Also, it is best to use a fan heater before bed, or first thing in the morning, to prevent overheating. You should also keep the heater at least a few feet off the ground. It is also important to make sure that it is placed away from the side walls and is not too close to the thin inner tent.


If you’re trying to keep your grow tent warm at night, ducting is the way to go. Ducting can keep the tent warmer than it is during the day by pushing air into it and out of it. It will also help your plants survive cold air shock. You can run flexible ducting from an intake fan, wrap it around the grow tent, and plug the other end. Or, you can cut slits in the ducting to allow the air to flow freely.

When selecting ducting, it’s important to make sure that the size of the filter is large enough for the space you’re growing in. Many grow tents have too small of an area to fit a carbon filter. Besides that, you’ll need a way to install a fan. A fan is a good way to move air, but it can also be a hassle to hang and move.

Air conditioners

Air conditioners are a great way to keep your grow tent comfortable. They can help maintain a comfortable temperature and also remove moisture. They also have a HEPA filter that keeps your tent free of dust. These units also come with a 1-year warranty. They can be installed easily without requiring any professional installation.

A grow tent that is too warm can cause a plant to die. You can remedy this by using an air diffuser to keep the temperature even throughout the night. It can be made of flexible ducting that can be run from an intake fan and wrapped around the grow tent. You can plug the end of the ducting or cut slits in it to distribute the air.

Strong exhaust fan

If you have a small grow tent, you can use a 4” exhaust fan with a carbon filter. Larger tents may need a 6” inline fan. This type of fan can have two speeds and can expand if needed. Just remember that the further the exhaust fan travels, the lower the airflow will be. To make the most effective use of your exhaust fan, connect it to the tent through a short ducting or straight path.

Another great feature of an exhaust fan is its on-board variable speed controller. This allows you to lower or raise the fan speed to keep the tent cooler. Some fans also feature a carbon filter to reduce odors.
