Best Heater For Grow Room/Grow Tent: 2023 Reviews And Guide

Last Updated on June 5, 2023 by Georgie Smith

Seasonal changes can deal your grow room a huge blow, and it may mark the beginning of the end for a lush, healthy farm. Winter frost and summer heat are some of the adverse conditions that are hard to cope with for most plants. Thus, a question many farmers often ask is; what is the best grow tent/room heater?

Indoor plants such as veggies, fruits, and flowers require an average temperature of 24 Degrees Celsius for maximum yield, and this can be hard to achieve without the right heater stationed somewhere in the room. Moreover, while most heating systems have heat regulators, it is essential to buy the best among many.

However, before settling on the right choice, it is imperative to note that the amount of space in a grow tent matters a lot. It is to say that grow room heat emanating from a heating system should be able to radiate across the place to all the plants, including those which are underneath taller ones. With this in mind, you must thus station the heater in a central location.

In this post, Morninghomestead reviews some of the best heating solutions for your indoor farm so that plants can retain a cozy feel and survive through harsh weather conditions. However, first things first, you are interested in finding out why you need a grow heater.

Benefits of a Grow Room/Grow Tent Heater

Indoor growers with experience would not fuss about this. However, for someone with little experience in farming methods that require a grow room such as hydroponics, Aeroponics, and Aquaponics, understanding the basics should mark the beginning of happy days.

No one should start building a grow tent only to lose everything at the onset of winter because he or she did not anticipate having a grow room too cold.

So it is okay to ask, how will a grow room heater benefit my farm?  Well, here are some notable points:

  • Temperature changes can sometimes be unpredictable. A standby heating system will, however, help you overcome such challenges in the nick of time.
  • In cases where grow lamps or bulbs are not emitting enough heat to make the room warm, a heater becomes a vital necessity for those practicing hydroponics.
  • Heaters also make it possible to achieve optimal temperatures.
  • When there isn’t enough heat or none at all coming through to a grow tent, it is imperative to acquire a heater.
  • Grow rooms in stationed areas away from a furnace require their heating system. [1]

What Features to Look for in a Heater

Situations, where people buy the wrong heater for their indoor gardens, are common. Sometimes this happens because many do not find out beforehand, features that define the best heating accessories.

No one will victimize you if it is the first time you are doing so for your farm, but it should not be a justification for taking home a substandard product all the time.

It is the age of information plethora, everything you need to know is always a click of the button away. If you cannot find the best guidebooks on grow room heat problems, a quick online search will save the day. Now, here are some essential features you need to look for when purchasing a heater:

Power Consumption

Rating of power is in watts. While it is necessary to buy one that will generate enough heat, you would not want to end up paying way abnormal power consumption bills. Heaters can consume power more than 1500 watts.

Temperature Regulation

Does your grow tent heater have digital temperature settings? Operating one on guesswork is the last thing you should do. Look for a product that comes with a digital temperature calibration reader.

Safety Precautions

While most products will come with a user manual, good heaters should also have inbuilt safety features such as auto turn off and shut down when there is overheating. You should also be able to auto-set a grow room heater so that it shuts down on its own after a specified duration.

Method of Heating

Are you looking for a product that distributes heat waves with the help of a fan or a stationary one? It is a crucial decision to make before acquiring the right one.

Size of Grow Room

Grow tents are either big and small. While most heaters will work distribute heat to all corners of a growing place, it is critical to look into this issue before settling on the best choice.

What Kind of Heater Should I Use in Grow Room/Grow Tent?

It is essential to focus on practical solutions when choosing the best heating option for your indoor garden. You are likely to come across different ideas regarding this, some of which may sound very new and may throw you into a state of confusion.

Do not fret. There are as many approaches to this vital activity as you can think. The options are unlimited. Morninghomestead will review top choices you can buy from Amazon shortly, but in the meantime, the following will interest you:

Heat Lamps

These were popular in the past. Moreover, while you may want to try them out, it is imperative that you will need to keep watch over soil moisture. It is hard to regulate this heating option, and if you are not careful, the foliage of your plants may wilt and dry due to excess heat.

Compost Heat

Yes, you can provide warmth to plants using heat coming out of compost. It has been an option for greenhouse growers for many years now, and others are still using it. The compost acts as a heat sink. You may want to ask; how is it done? Well, all you need to do is fill a trench dug in a grow room with compost. It accumulates enough heat during the day when the temperature is a bit high for use in the later hours.

Insulation Heating

It may not be the best in the face of modern grow room heater options, but it can help with your day in situations. With this option, you will need an insulating material to cover the grow room (More or less like those used in greenhouses).

Water Storage Technique

Not everyone can think about this, but it has worked. A dark storage tank which you then station near a grow room is preferable. By the day, it absorbs enough heat energy which is later emitted to a grow tent at sundown.

Soil Mat

They could sound crazy for someone who has never tried it. Grow tent heat mat happens to be one of the many options a grower can settle on, and it is pretty simple. Instead of heating the surrounding air, you do it on the soil mats.

It is a great option not only for plants but also when germinating seeds. You place heat mats under grow trays or pots then apply heat. The resulting warm gets emitted upwards.

Electrical Grow Room Heaters

It is the most popular and advanced. Electrical heating appliances for indoor gardens are available in shops near you, but you can also buy one from Amazon at an affordable price. This post looks at this option by reviewing some of the best heaters on the market.

What’s the Best Way to Heat?

Truth is most growers are already using a heater in their farms, but for those who are yet to do so, this post should help you buy the best one from Amazon. In spite of this, there are significant questions that you must try and answer. For example, what kind of heater should I use in a grow room?

There are many conventional ways of warming up your plants, but it is ideal to use modern heaters with regulators for controlling overheating. Modern commercial garden tents require robust systems to achieve this, and it is why you must go out there and buy the best heater.

You may want to hang the heater somewhere in the room or place it in some corner. They are no restrictions as to where it should be. However, it should not be too close to the plants, or it will burn the leaves. A heating fan makes it possible to dissipate heat to every place in the room.

Closet grow room supplies


People do ask many questions about heaters for grow rooms/tents. Below are some of the most common ones:

Q:  What is the best way to use a heater in my grow tent?

A: There isn’t a standard way of heating. You can place your heater inside the tent or outside. However, the size of the canvas always matters because, by it, you can determine the most central position for the appliance. In cases where the room is big, you need a heating fan to distribute heat to the furthest areas.  It is unthinkable to use heaters outside large tents.

Q: How do I choose the right heater based on room size?

A: This is a common question. Well, there are two main types of heaters, namely, oil-filled and ceramic. The latter is ideal for smaller rooms while oil-filled heaters are popular with medium and bigger room sizes.

Q: How much will good heaters cost me?

A: The market has the best in stock, and while it might have been challenging choosing one (but not anymore after reading this post), cost varies. Sometimes it is about size, wattage or type. However, one should be able to save extra bucks when buying heaters from Amazon.

Q: What is the best time to heat?

A: Fluctuations in temperature should be able to help you make this decision. In the evenings, temperatures fall, and it could be the perfect timing. During winter, heating systems are a necessary evil for indoor plants.
