If you’re one of the lucky few that live in a hot climate, you’ll probably only need a grow tent heater every now again for the odd cold night, but for many growers that live in places with changing seasons, temperature control, if not regulated properly, can cause serious problems such as mold (bud rot) or even crop failure.
For these growers, they know winter is coming and they’ll need to think about keeping the plants’ roots at an optimal temperature, so depending on their grow room, plus if the plants are auto-flowering or not, then the solution may be to incorporate a grow tent heater or multiple grow tent heaters.
So in this article, we’re going to try and answer some of your questions about grow tent heaters and save you from the many wasted hours online trawling through sites by highlighting some of the best-reviewed grow tent heaters out there.
One of the most recommend heaters among growers for any set-up is the oil-filled radiator. With that being said, you can do much worse than opt for the Pelonis oil filled space heater when looking at this category. Consistently rated five stars, the six fin Pelonis oil heater would be ideal for any small to medium grow set-up.
It comes with multiple heat choices, with the highest running at 1500W and the lowest 600W, while the middle setting runs at about 900W. As well as the three heat settings, the Pelonis space heater features an impressive LED display with five large easy to use and read buttons as well as a 24hr timer.
An added bonus to the above is the inclusion of a remote, so choosing the right settings is made even easier.
If your one of the unlucky ones to experience problems with the Pelonis oil filled space heater, then don’t worry too much, as the heater comes with a standard one year warranty.

4 heating modes
Remote control included

The De’Longhi Convector Panel Heater is another option for any cannabis cultivator struggling to find adequate growing space. It’s just as safe as the Pelonis oil filled space heater while running at a similar wattage at 1500W.
As the name suggests it’s slightly different in design and comes as one rectangular thin convector panel rather than your fin radiator design.
For anyone with a small to medium grow setup this can be seen as a bonus, as it’s much thinner so can fit into a smaller area without causing to much trouble.
Convector panel heaters can be just as efficient as oil-filled heaters and are amazing at heating up the whole grow room quickly.
It’s claimed convector panel heaters are some of the best for using in cannabis grow rooms and are better for heating multiple plants at once, rather than just a single plant.
The De’Longhi Convector Panel Heater chooses to incorporate an LED display instead of the more simple design of dials, these are normally positioned to the side panel.
It also comes with an adjustable thermostat, which is sufficient enough for most people’s needs. As well as a timer and an energy-saving option.
Safety features of the De’Longhi Convector Panel Heater come in the form of an internal overheat sensor, which will switch of the heater if it ever becomes too hot, an automatic cut off switch if the heater is ever tipped over, as well as caution indicator lights.

The DIMPLEX 1000W 30″ Wireless Heater is mini in design but packs enough of a punch to be included in this list. Consistently rated four stars and above, the consumers that have bought this little powerhouse have not been disappointed.
It doesn’t come with as many heating options as some other heaters but is becoming ever more popular among the growing community for the heat they produce whilst also saving on space.
These baseboard heaters are ideal for full grow rooms when more than one heater is required.
Where the DIMPLEX 1000W 30″ Wireless Heater falls short on its heat settings and installation process, it more than makes up for with its small compact design and efficient heat production.
The smaller DIMPLEX Wireless Heater models are also an ideal solution for those with smaller grow tent setups and do the job of keeping your roots at an optimal temperature considerably well.
With a high-efficiency thermostat, easy installation, warranty of 10 years for elements, a 1-year unit warranty plus CSA certified. The DIMPLEX Wireless Heater is another popular option for cannabis cultivators.

The Costway electric portable infrared quartz heater is another good quality product that includes enough settings to satisfy most indoor growers, it’s priced reasonably well, offering cultivators on a budget another fantastic heating option.
The Costway space heater uses fan circulation while also rotating side to side to create heat and direct it to your chosen area. It’s compact in design and has three heat settings which are high, medium and low, with the highest heat setting running at 1500W.
As well as the three heat settings, Costway has included a 12hr timer, LED display, and an easy to use remote which features sensitive response and ultra-long sensing distance.
Three safety features are included in the Costway electric portable infrared quartz heater. The first being your standard overheat sensor, which is always top on most people’s safety list, a tip-over sensor for any mishaps, and also a child locking feature. Although the last feature probably won’t be used by most growers, it’s always a handy feature to have.

But just like their fans, VIVOSUN make a pretty decent and affordable heat mat with the bonus of a thermostat included, the VIVOSUN 10″x20.75″ Seedling Heat Mat and Digital Thermostat to be exact.
Again, ideal for anyone on a budget that would prefer to use heating underneath, rather than a standalone heater.
The VIVOSUN 10″x20.75″ Seedling Heat Mat and Digital Thermostat is one of the best-reviewed heat mats out there at present, and cheap to boot and quite often rated at four stars and above.
Making it one of the more popular choices from the big online retailers, although some lower reviews have been known.
One downside of the VIVOSUN 10″x20.75″ Seedling Heat Mat and Digital Thermostat is that it only comes in one size, which isn’t exactly great.
It’s an easy fix though, as multiple heat mats can be attached to achieve the required results.

If any defects do present themselves, then VIVOSUN has a 1-year warranty that is more than adequate.

A grow tent heater is a piece of equipment that can produce heat which is then directed to a specific area, be it a room, object so to increase the temperature of the intended target area.
Most are quite expensive to run on a continuing basis, and will generally need an electrical mains supply, although there are other options available, propane etc.
The design is mostly of an upright rectangle or square design, but can sometimes be round or oblong, prices vary and can range from under $50 into the $1000, and hundreds of options are available. They can also be static, fixed or oscillating, in terms of grow rooms always opt for oscillating when space will allow.
The choice of what grow tent heater to buy for your grow room, again just like grow tent fans will come down to the growers’ personal preference, the size needed, the price of the grow tent heater and what’s commonly recommended and used by other cultivators.
But to be honest there’s not really a definitive right answer to the question, what heater should I buy for my grow tent?
We’ve previously mentioned the importance of your grow tent fans needing to be oscillating, the same can also be said for your grow tent heaters.
Sometimes this is not always practical depending on your grow room and the amount of free space available, so you may opt for a static/fixed heating solution instead.
But where possible, we’d always recommend going for grow tent heaters that incorporate the oscillating feature, as oscillating will always mimic the plants growing environment and circulate the heat much better.
As well as your traditional grow tent heaters, heating mats and even heat tubes are sometimes recommended and used in grow rooms. Basically, there’s a multitude of options out there, so do your research thoroughly.
Some of the most popular and recommended grow tent heaters are:
Grow tent heaters play an important role in most grow rooms, this can be especially true when growing in the winter.
More than likely you’ll be growing in a confined area as well, and will need a grow tent heater that fits the requirements of being small enough for your grow room, but also producing enough heat to keep your plant roots at an optimal temperature.
There’s a plethora of choice in the grow tent heater market at present, and we’ve written about some of the better-reviewed ones that are currently available, and by doing so hopefully made the decision of what grow tent heater to buy that little bit easier.
