Popular Grow Tent Heaters of 2024 Compared

If you’re thinking about trying your hand at cannabis gardening – whether the finished product will be for your own consumption or if you’d like to use it to try and start a business – when it comes to growing, you have two options: you can grow outdoors or indoors.

While most novice cannabis farmers might assume that the latter approach is the best way to go (and while it may be in some cases), that isn’t always the case. You may have limited space, the climate you reside in may not be suitable for growing, you might want to be able to take your garden with you if you ever have to go, or you may just want to remain incognito, for example; in any of these types of situations, indoor growing would definitely be your best bet.

Indoor growing can yield some great results, but in order to do so, you need to make sure that you provide your plants with ideal growing conditions. One of the best ways to do that is to create a greenhouse by using a cannabis growing tent. As the name suggests, these tents function as a greenhouse, providing the plants with optimal conditions for growing; however, in order to further improve those conditions, a grow tent heater is a definite must. 

As you can probably guess, a grow tent heater is kind of like a space heater, but it’s specifically designed to be used inside a grow tent. It generates and controls the heat within the tent, and it may feature a rotating fan or a circulating air system, which helps to circulate the heated air so that the plants can be evenly heated.

Grow tent heaters can really help to increase your yields and produce higher-quality, more abundant plants; in fact, many cannabis farmers highly recommend using these handy devices, and claim that they are an absolute must. 

Of course, like so many other products that are on the market for cannabis growers, there are so many grown tent heaters available. While choice is always a good thing, with so many options, trying to decide which one will best suit your needs can seem like a daunting task. No worries mate! We’ve taken the liberty of doing the research for you, and we’ve narrowed down our top picks below.

Herb CEO Summary

A grow tent can be a great way to farm cannabis. In order to ensure the success of your crops and produce higher yields, you’ll definitely want to invest in a grow tent heater. With any of the options featured on our list, you’ll be sure to provide your plants with the ideal growing conditions. 

What kind of heater do I need for a grow tent?

The type of heater will be dictated by the size of your grow tent as well as where the tent is located. If your tent is in a climate controlled building like a house you don’t need a heater. However if you are growing in a cold basement or outdoors you’ll need a heater to regulate temperatures.

Is it safe to have a heater in a grow tent?

Heaters in tents and/or indoors should be monitored at all times. Furthermore it’s best to invest in a heater that was designed to be used in a grow tent as opposed to using less-safe generic space heaters which have fewer built-in safeguards.

How do you keep heat in a grow tent?

Ideally by placing the tent in a temperature controlled building or even your house. If you control the temperature externally you won’t have to worry about the tent retaining heat because it’s surrounded by a healthy ambient temperature. Keeping your tent closed will also help keep the heat from escaping.
