Benefits of Getting a Heater for Your Grow Tent or Grow Room
Just like humans, plants also have their preferred environment for maximum growth and potency. Every gardener knows it’s essential to build an optimal growing environment for plants, especially marijuana.
Since your grow tent or grow room is always sealed or closed, however, it’s highly possible that the environment inside the grow tent is not as friendly as the outside, meaning that your setup conditions may not generate enough warmth (heat) for your plants. That explains why a grow tent heater is a must for novice cannabis farmers.
A grow tent heater, kind of like a space heater, is intended to be used in a grow tent or grow room and gives you more control over the temperature inside. You can use a heater to increase or decrease the heat in your grow space until the temperature reaches optimal, making it more favorable for cannabis growth.
What are the Types of Grow Tent Heaters
There are many heating options to increase the temperature in a grow tent, including gas, electric, and other kinds of heaters generally used in the home, each of which has its own features and uses. We’ve sorted out several common types of grow tent heaters used by most gardeners to help you select the best one that suits you.
As the name suggests, an electric heater converts electrical energy or electricity into heat energy rather than gathering heat from the surrounding environment directly.
A ceramic grow room heater is usually ideal for small spaces or areas. Thanks to the heating element of PTC, it can quickly warm up a room.
An oil-filled heater runs on both electricity and oil. It warms the air with oil-filled fins and consumes less electrical energy. In this type of heater, oil is considered a heat reservoir to generate the heat the grow tent requires.
This type of heater is efficient. It simply uses the water to transform the heat throughout the growing space. You can use it both in your small grow tent or in the whole house.
Duct fan heaters may be less known. Often as an integral part of HVAC, it can also be used to heat your grow tent and is ideal for farmers looking for space-saving options.

How to Choose the Right Grow Tent Heater
Using a heater can help to give enough warmth and secure a maintained temperature in your grow tent or grow room for minimal energy. Here are a few things to bear in mind if you’ve decided to look for a grow tent heater.
Required power is especially an important concern if you plan to buy an electric grow tent heater. You need to check how much power is required to run the heater. It’s closely associated with the electric bills you’re going to pay. A grow tent heater with a high power intake will cost you a lot of money and become a burden for you.
Type of Heater
As we mentioned above, there are several types of grow tent heaters. You need to know which kind suits you best.
Anyway, if you prefer more heat, ceramic heaters may be an ideal choice, compared to other kinds, which use a ceramic element to generate heat and have fans to distribute the heat to each corner of the grow space.
Type of Heat
The heat, determined by the type of your heater, can be either good or bad for your cannabis plants. For example, infrared heat harms your plants. So it’s essential to check what heat the grow tent heater you’d like to buy is producing.
Size of Grow Tent or Grow Room
Always remember to check how big your grow tent or grow room is because grow tent heaters are designed in various sizes to suit rooms of different sizes. The amount of warmth a heater can generate is mostly dictated by the heater’s size.
Large grow tent requires a bigger grow tent heater to produce massive heat for even distribution. A heater will be of no use if it’s too small for the space.
Safety is also a highly essential consideration that you should never ignore. You always need to check the safety features of electronic appliances, including grow tent heaters.
Good and safe-to-use heaters typically come with advanced safety features, such as over-heat and tip-over protection. This suggests that the heaters will automatically stop working if overheating or tip-over occurs. These settings are crucial to avoid bad accidents like catching fire.
Make sure the grow tent heater you want to buy is efficient. Efficient heaters need less power and are more environmentally friendly without causing harmful waste.
Auto Power System
Nowadays, some heaters are designed with this feature. It’s perfect for busy people who don’t have much time to care for their grow room and plants.
Ease of use
Another important factor you should take into account is whether the grow tent heater is easy to use and assemble so that you don’t have to waste a lot of time figuring out how exactly the heater operates.
Buying a grow tent heater with detailed instructions and temperature settings will greatly save you time and effort, making your life much easier. Besides, if you’re a person who has the need to know the exact temperature, you can select a grow theater with a display screen. It may cost you a little bit more, but considering the convenience, it’s absolutely worth it, right?
In fact, portability is not a very must for grow tent heaters. The portability of a heater largely relies on the size of the heater, more accurately, the size of the grow room. Small heaters are often more portable and easy to carry.
Some grow tent heaters are manufactured to be mounted or hung. They are space-saving options for people without much space.
So it’s utterly dependent on your needs and preferences to select one grow tent heater. Knowing your demands before buying is always a wise choice.
How to Operate a Grow Room Heater
Grow tents keep the temperature in your grow room at a perfect 70 degrees Fahrenheit, which is optimal for cannabis growth. The heater is powered by electricity and includes a thermostat for temperature control. You can switch buttons as you push to turn it on or off. Upon switching the heater on, it can already generate heat, and it will maintain a warm environment inside the grow room.
As previously stated in this essay, cannabis thrives best at temperatures ranging from 20 to 30 degrees Celsius. The majority of the grow tent heaters listed above are modest in size, making them simple to fit within the grow room. However, if the heater is too strong, it must be placed outside the grow tent.
It is essential to maintain the grow room sealed to guarantee that the grow room heater functions correctly. This will keep the warm air from within the grow chamber from escaping and the cold air from outside from entering.
FAQs About Grow Tent Heaters
1. Should I Put a Heater in My Grow Tent?
Yes. The heat from lights alone is usually not enough to guarantee that your grow tent is maintained at an optimal temperature. A grow tent heater will help you control the fluctuating temperature and make your tent a more favorable place for the robust growth of plants (marijuana). So you can yield some healthy benefits.
2. What Type of Heater is Best for a Grow Tent?
If you decide to grow marijuana inside, you can choose electric heaters over oil-filled heaters. Besides, a power of 300-400 watts is ideal for the heater to do its best.
3. How Do you Warm Up a Grow Tent at Night?
Grow tent heaters are good helpers. You can buy an electric heater to heat your grow space at night. The warmth produced by electric heaters is enough for plants, even in the coldest winters. However, you should remember not to directly blow the hot air into the plants because the heated air is dry.
4. Do You Need Ventilation in Your Grow Tent?
Absolutely. Proper ventilation in grow tents is crucial to ensure healthy plant growth. Good ventilation provides fresh air from the outside and supplies the CO2 the plants need for photosynthesis. It also dispels the air inside to keep the humidity and temperature inside under control.
5. What Temp Should You Keep Your Grow Tent at?
If you’re growing cannabis plants, the temperature should be kept around 70-85 ℉ (20-30 ℃) with lights on. When it comes to their night (with lights off), the temperature can be slightly lowered.
Besides, marijuana has different preferred temperatures at different stages. At the vegetative stage, cannabis plants are still young and happy with a little warmer temperature of 70-85 ℉ (20-30 ℃), as mentioned above. When it comes to the flowering stage, however, it’d be better to keep the temperature slightly lower, about 65-80 ℉ (18-26 ℃), because a slightly cooler temperature in the flowering stage can help make the best bud color.
6. Can the Normal Room Heaters Be Used for Grow Tents?
Yes, you can use normal room heaters in your grow tent or grow room. Just make sure that the heaters you have are equipped with adjustable temperature settings. It’s very important.
7. Do You Need a Heater Even If You Live in a Hot Place?
No. If the heat of your grow room or grow tent is already at an optimal level, then you really don’t need a grow tent heater to control the temperature. If you’re living in a hot place with a high temperature inside the tent, you may need to use an air conditioner instead of buying a heater. A grow tent heater is merely designed for growing plants in very cold places or in winter.
8. What Humidity Needs Do I Need to Take Care of Plants in a Grow Tent?
Humidity is another critical factor in growing plants. At the early stage of growth, a humidity level of 55-60% is ideal for healthy plant growth, while at the flowering stage, the humidity should be reduced to around 40%-45%. Despite this, however, there is yet to be a specific answer. Different plants have varying requirements for humidity. Therefore, always check for that before actual growing.
9. Can I Grow Cannabis Plants Without a Heater?
Sure. Gardeners who grow cannabis in places with ideal weather conditions do not need to use a grow tent heater.
10. What Factors Should You Consider While Growing Marijuana, Except the Heat?
There are many other factors you need to pay attention to for marijuana growing, including lighting, nutrition, grow tent, ventilation, humidity, etc.
So, if you think you’re ready to get started, go ahead and start looking for the perfect grow tent for you. The output you need will undoubtedly be determined by the kind of grow tent heater you choose.
If you make the incorrect choice while selecting a growth tent heater, your plants will suffer greatly. On the other hand, grow tents will be helpful for indoor gardens, and the best thing to do is to get the finest grow tent heater available on the market, which has significant heating mechanisms with minimal power input!
