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.

Making it one of the more popular choices from the big online retailers, although some lower reviews have been known.

Consistently rated five stars, the Pelonis double-layered covered 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 and digital thermostat.

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.

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.

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.

What is a Grow Tent Heater?
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 or object/s 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.
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 cannabis 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 or grow room?
Some cannabis growers will incorporate a heater inside of the grow tent, obviously, this isn’t ideal, but does work and can produce the required results.
Bear in mind though, the heater would need to be of a smaller size and there’s also the real possibility of it being a fire hazard.
The best practice is to place your chosen heater on the outside of the grow tent, or if you have a full-sized grow room opt for multiple oil-filled, panel or baseboard heaters.
Heat mats and heat tubes are other affordable options that many growers incorporate into their grow rooms with varying results. Obviously, heat mats are more commonly used for seedlings.
But by connecting several of these mats together and placing them underneath your plants you can achieve similar results to the more conventional heater.
Some growers have even used outside heat mats as a sort of underfloor heating method/technique. These would normally be used for melting snow and ice outside, so again there’s a safety issue here. So consider every aspect carefully before going ahead.
Tube heaters can/are used, but are a bit hit and miss depending on what brand you choose to purchase. The Dimplex tube heater is one of the more popular among indoor growers.
A great technique for underplant heating is to place one or more tube heaters inside of a wooden pallet and place underneath your cannabis grow, you should see some good results from this method.
Again, use common sense to any heating options you choose to use. Safety is paramount, the last thing anyone wants is a potential fire situation.
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 tent, 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.
