Best Grow Tent Heaters 2020


The first natural goal of cannabis farmers is to maximize their crop quality. We all want to use the most efficient growing methods to optimize our overall yield quantity. However, to make the most out of efforts, you have to get full control over your indoor garden. This also includes temperature control, that you can keep at an optimum level with the best grow tent heaters.

Keep in mind – fluctuating temperatures can be dangerous for your crops when it comes to growing cannabis. When you can mimic the transitions between summer and winter for indoor gardens using tent heaters and temperature controls, keeping the temperature to the optimum level is a challenge.

Benefits of an Indoor Heater

The ideal temperature range to optimize your plant growth is about 18C to 25C or 65F to 77F. During the vegetative phase, a warmer environment is better, which is around 20C to 30C or 70F to 85F. Nevertheless, during the flowering phase, 20C to 26C or 65F to 80F is appropriate.

In the absence of natural climates, extremely low temperatures may result in an unhealthy environment. This can hinder healthy plant growth, photosynthesis, flowers blooming and development, and seed germination. 

On the other hand, marijuana plants also suffer in colder temperatures as they’re highly susceptible to mold growth that’ll affect the general harvest quality.

Here are some of the key benefits of the best indoor heaters.

  1. Heaters help to achieve and stabilize optimal growth temperatures.
  2. Grow tents or rooms with no heating source or limited heating capacity can use a heater to create a healthy growth environment.
  3. With a standby heating system helps in overcoming the challenge of unpredictable temperature changes.
  4. There will be times when grow lights don’t emit enough heat to warm up the area. Simply put, a heater maintains a constant temperature, particularly when LEDs are involved.
  5. If you are located in a cooler climate, a heater can be a lifesaver.
  6. If the growing area is far from natural heat sources, it requires its own source of heating. 

What Characteristics To Look Out for in a Grow Tent Heaters

It can become pretty overwhelming when shopping for a heater for your indoor garden. To buy the best product, you need to do prior research into types of heaters, brands, heating accessories, key features, and additional benefits. The following horticulture specific features will help you avoid substandard products and invest in a useful, explicitly for greenhouse use, heating tool:

Power Consumption

The rating of power is measured in Watts that directly affects your energy bills. The higher the watts it consumes, the higher the bill. 

It is best to note that heaters can run up to, and even exceed 1500W. It is essential to buy an energy-efficient heater that generates just enough heat without contributing to abnormal power consumption bills.  

Temperature Regulation

Precision is key when it comes to good cannabis growth. Investing in a grow room heater that is accompanied by a digital temperature calibration reader can be a useful aid. This digital-specific temperature control helps you to avoid detrimental and time-consuming trial and error rounds. Thermistors and thermal fuses prevent electrical surges.

Size of Growth Operation

Heat distribution is interlinked with the approximate size of the room. Measure your room and calculate the heat distribution you require before making a purchase.

Heating Method

Consider whether you want a fan or stationary heater to dispense heat waves.

Automatic Turn-Off

Some heaters shut down on their own when they heat up. This may be a useful safety feature for some people.  

Additional Safety Features

If you want a premium quality heater, make sure it comes alongside a user manual, inbuilt safety features, and auto-time settings that allow for specified time durations. In addition, low probabilities of tipping over with a low center of gravity and cool construction materials are also key features for a durable product.  

Types of Indoor Grow Tent Heaters

Looking for practical solutions when it comes to choosing the most suitable heating option for your indoor gardening? If yes, the first thing you need is to learn about the different types of indoor grow tent heaters. 

Here is a quick list.

Ceramic Heater

Ideally utilized in smaller rooms, ceramic heaters are available in two primary forms. These heaters use a ceramic heat stone instead of an exposed heating element and sometimes feature a fan.

  • Radiant Ceramic Heater: Convection heat to circulate throughout the area.
  • Connective Ceramic Heater: Direction-oriented heating.

Rapid heating is definitely an advantage offered by ceramic heaters. However, be aware of the quick cooling down after shut-down as well. These are inherently safe for indoor use because of non-heat absorbing plastic encasing, no hazardous emissions, etc. Waterproof versions are also are available. 

However, if using one, we recommend you not to leave these heaters unattended overnight. 

Oil-Filled Heater

Recommended for medium to large-sized rooms, these powerful heaters are slower to heat up but offers constant heat. Physically these resemble traditional radiator heater. Appropriate for 24/7 use, it features fins filled with oil that is heated to increase temperature levels.

Burns and replacements are non-existent along with zero production of combustion gases. They’re low power consumers as they retain heat post shutting off due to the heat reservoir. As they do not reduce humidity or burn oxygen, they are also safe to use. Waterproof versions are also available. The only downside is the initial expensive price, but they last really long.  

Propane Heater

Propane gas heaters are powerful machines that fit the needs of larger rooms. It is easy to install, lower relative cost, low maintenance, and quick to heat up. 

However, in the absence of venting, emissions may harm plants. Be wary of the flammable fuel. It is safe to use overnight as most come with automatic shut-off features. Waterproof versions are available.  

Tubular Heater

You can use Tubular Heaters both vertically or horizontally. The fluorescent light lookalike heaters work well in smaller tents.  

Alternative Heating Methods

Here is a list of some other methods that you can use to heat your grow tent, but probably not as effectively as with heaters.

  • Electrical Grow Room Heaters.
  • Soil Mats: These are simple to use and highly useful when germinating seeds as the temperature is maintained between 75F-85F. The heat moves from the ground up, underneath pots and seedling trays. 
  • Water Storage Technique: Eco-friendly option, absorbs natural heat energy during the daytime and emits to the grow tent at sundown.
  • Insulation Heating: Seals off the growing area to prevent external airflow from lowering temperatures. 
  • Compost Heat: Compost acts as a heat sink, absorbing heat energy during the day for later use.
  • Heat Lamps: You can use heat-producing lamps to increase temperature. However, you must monitor soil moisture as the use of these increases the chance of foliage burn and drying out.
