Buyer’s Guide

What a Grow Room Heater Is?

A grow tent heater is a device that generates heat and directs the hot airflow to a particular area. Its purpose is to raise the temperature in a room, tent, or other space. There are heaters created specifically for indoor gardening, or you can apply the universal device with the required functions.

The design can be various, but in most cases, this is a box with a heating element and a fan, which directs the warm air. But there are also radiator models without a fan. Some devices might have a rotating or portable feature to ensure even heat distribution.

The two most common types are ceramic and oil-filled heaters. In the first option, the device has a ceramic heating stone that generates heat. This is the model, which likely has a fan.

These items are best for small areas. Oil-filled grow room heater with thermostat is usually bigger, and it takes longer to heat this device. However, this type works for large rooms and generates sufficient heat.

How a Tent Space Heater Works?

Let’s take a closer look at the heater’s work. For growing weed, you should maintain the right temperature inside the tent, especially in cold seasons. That is why we apply heater devices, which warm up the air and allow maintaining the tropical climate inside the tent even during cold seasons.

The heater usually has a thermostat for adjusting the temperature and controls using the electricity. Also, there can be a selection of modes, fan speed, timer, and other features for convenient use.

Compact devices are perfect for small rooms or directed heating. Bigger and more powerful models will help you in warming up large tents. To ensure effective heating and wise power usage, make sure your tent is securely sealed to prevent the warm air from coming outside.

How to Use a Grow Room Heater Safely?

Keep in mind that using plant heaters indoor requires a careful approach. This is a heating device that works from electricity and is usually placed in small spaces. Therefore, here are some rules for using the heater safely and save your harvest:

  1. Choose the right place. The surface should be hard, non-burning, and stable. Most of the heaters are intended to stand on the floor. If this is a wall model, make sure it does not hang next to the wooden or other burnable objects.
  2. Do not place the combustible objects and materials next to the heater. Ensure the curtains or other cloth does not reach the device.
  3. Keep the heater away from the paint, gas cans, matches, and other easily flammable objects.
  4. Create a safe surrounding. Make sure there are no kids or pets near the heating area.
  5. Do not leave the heater turned on at night or for a long time without supervision.
  6. Unplug the device when you do not use it. Make sure the cord is not damaged or worn up.
  7. If you use an extension cord, do not plug in other devices into the outlet in order not to cause overheating.
  8. Look for devices with safety features like thermal or lean shut-off, sturdy cord, cool-touch surface, etc.


What Features to Consider in the Best Grow Tent Heater?

If you cannot choose one of the products from our reviews, you can try to find the perfect model by yourself. But we will not leave you without help here as well. Regardless of your approach to the making-decision process, you should know what features to consider before buying the particular heater.

  • Power usage. This parameter is measured with watts, and this is the number you should look for. Heaters require a lot of electricity, and it can be expensive to use them all the time. So, look for powerful models, which can heat the room quickly, and then you can turn it off.
  • Temperature regulation. This is a convenient option for adjusting the heater performance. In growing weed, you should maintain a particular temperature, without making the air too hot. That is why adjusting settings will be handy here.
  • Heating method. There are two types of heaters: stationary and with a fan. The first one is an oil-filled model that provides powerful heating around itself. The devices with fans are usually smaller and produce directed warm airflow.
  • Room size. Keep in mind that for large grow rooms, you should buy a potent heater or a few smaller models. Also, do not place the strong heating device inside the small tents in order not to cause overheating.
  • Automatic turn-off. The good heater has two auto shut-off functions: thermal and anti-lean. The first one turns the heater off when it is too hot, while the second feature activates in case the device falls.
  • Additional safety features. These can be a timer, cool-touch surface, alarm, and special construction, which prevents tipping over.

However, we still recommend you to look for the professional room heater review before buying one. This is how you can get the complete estimation of the device and decide whether it is suitable for your gardening needs.

FAQ About Plant Heater Devices

Here is some extra info about the room heaters and their usage. Look through these questions to enlighten anything that may still be unclear.

What size should be the room for the grow tent heater?

Depending on the size of the grow tent, you should pick a suitable heater. For small rooms of up to 50 square feet, you can apply compact models. For bigger spaces, you should use more powerful heaters, or a few small ones placed evenly throughout the room.

What kind of heater is right?

As we already said, the suitable model is defined by the room size, the outdoor condition, and your gardening needs. Most weed growers prefer to install oil-filled devices in big rooms and ceramic heaters in small ones.

What happens if the grow room is too hot?

Too high temperature is harmful as well as low. When it reaches 80°F (26°C) and more during the flowering stage, the growth of the buds will slow down, and they will be airy. The heat also influences the smell of the plants.
