    Why We Like It

    This space heater would make a great addition to any grow room. We like the efficient and reliable heating as well as the ease of use. Furthermore, the safety features ensure that no harm is made to your plants while operating.

    Product Overview

    This oil-filled radiator is an excellent addition to the grow room. It can be used for different sizes of grow rooms, from small to medium.

    During testing, we observed that the heater heats the room quite quickly. Considering that most oil-filled heaters take some time before heating a room, this comes as a pleasant surprise.

    It comes with 7 fins installed. It also features a power choice ranging from 600 to 1500W. Thus, it can comfortably heat rooms up to 200 sq. Ft.

    We like the way the fins distribute the heat evenly across a room. It also makes sure the heat flows freely and efficiently.

    Energy Consumption & Other Features

    Despite the decent this device produces, the energy consumption is relatively low. This is due to the ECO setting, which makes sure the heater uses the least amount of power necessary.

    Since you are using this in a grow room, the sound might not be a concern. Nevertheless, the heater produces very little noise during operation.

    Ease of Use

    The heater’s controls are really simple. The LCD lets you know exactly what settings the heater is on. With the adjustable thermostat and timer, you can choose different settings conveniently.

    Furthermore, the heater comes with a remote control that allows you to manage settings from a distance.

    Safety

    Safety is vital, and the Pelonis space heater delivers well in this regard.

    It comes with an integrated overheat function that shuts off whenever the heat reaches dangerous levels. Furthermore, it features anti-freeze and anti-tipping features.

    Pros

    • Efficient and reliable heating
    • Innovative safety features

    Cons

    We loved the way the fan noiselessly carries on its function. It also ensures that the hot air circulates and penetrates every angle of the room.

    Product Overview

    This is a powerful heater that carries out its job with great effectiveness. It consumes up to 1500W, which is enough for heating a medium-sized room. Furthermore, it comes installed with six fins that allow it to distribute the heat around the tent.

    The operation of this heater is fairly quiet despite its power.

    It comes in 3 basic modes: High, Low, and Eco. The space heater also features a 10-hour timer that allows you to set modes ahead of time.

    It is very easy to use as it comes with remote control. You can adjust the temperature, set the timer, toggle between the different heating modes, and a few other functions.

    Safety

    The heater comes with safety features, including a tip-over option that shuts off the heater once it tips over. It also comes with a thermal cut-off option that mitigates overheating.

    Other Features

    The wheels and the carry handle of the heater ensure that it is straightforward to move around. It has a tower design that takes up as little floor space as possible.

    We love that despite having quite a long cord, the manufacturer has created a port in the heater where you can fold the cord in. This declutters your tent and makes it more organized and safer.

    Grow Tent Heater Buyers’ Guide

    When choosing a heater for your grow room, you need to consider a couple of factors. These factors are similar to those you would consider when buying a heater for your room.

    However, you need to pay closer attention than usual. Why? Because plants are more sensitive to temperature changes than humans.

    Even a little change in overall temperature can affect their behavior. Therefore, before you buy any heater, you must consider the following factors:

    Room Size

    There are different sizes of heaters, and in many cases, the size of the heater affects the amount of heat it can produce and distribute.

    If the grow tent is large, you will require a heater that produces a lot of heat for all the parts of the tent to be reached. If it is a small grow room, you can opt for a smaller or less powerful heater.

    The size of the grow room is an essential factor to consider when choosing a heater.

    Type of Heat

    The type of heat provided can either be beneficial or detrimental to the plants. For example, if the heater gives off infrared heat, this will most likely harm the plants. You need to recognize the type of heat it is giving off. Is it using a fan to circulate the air or something else? Is it an oil-filled heater?

    These factors need to be carefully considered.

    Power Consumption

    Although not true in all cases, the higher the power consumption, the more heat generated. You need to factor in the amount of power a heater draws before you buy it.

    While you need a heater that is capable of heating the entire grow tent, you should keep an eye on the power consumption. A heater with high power consumption will increase your electrical bills.

    Ease of Use

    It is frustrating spending money on an appliance and having a torrid time figuring out how to operate it. Therefore, when you want to buy a heater, ensure it is easy to install, use, and operate.

    A heater with temperature settings is usually a good bet. That way, you do not have to guess the operation mode. Some heaters come with a display that shows you exactly what is going on with the heater, for example, the current temperature settings. These heaters are often great choices.

    Safety

    As with every appliance, safety is paramount. Your heater must be safe to use and have protocols in place to prevent accidents.

    Some of the important safety features found in the best grow tent heaters are: Overheat cut-off and anti-tipping. With these features, the heater cuts of power and stops working until conditions return to normal.

    Size and Portability

    If you have a small grow room with limited space, buying a heater that is portable and takes little space is vital. Some can be mounted or hung to allow you to maximize space in the grow room.

    Type of Heater

    There are two common types of heaters. These are:

    • Ceramic Heaters
    • Oil-filled heaters

    Ceramic Heaters are heaters that employ a ceramic heat stone to generate heat. These heaters produce a lot of heat, but not as much as oil-filled heaters. These heaters have fans to disperse heat and are especially suitable for grow rooms that are small in size.

    Oil-filed Heaters, on the other hand, use oil to generate heat. Because of the medium of generating heat, they are slow to heat. However, when hot, they produce far more heat than ceramic heaters.

    They are ideal for medium to large-sized grow tents.

    Frequently Asked Questions about Grow Tent Heaters

    Why is a heater necessary for a grow room?

    Low temperatures can cause a variety of problems that can be eliminated by using a heater. Some of these problems include:

    • Poor Germination: if the temperature is too low, you cannot expect germination to take place. Plants need temperatures upwards of 60 degrees and even up to 80 degrees to germinate successfully.
    • Reduced Metabolism: if the temperature is low, the water plants need becomes has a higher oxygen concentration. And if plants draw up this water, it will negatively affect their growth.
    • Poor overall health: a damp, cold environment can lead to mold, cold spots, etc. This will eventually damage your plants.
    What factors affect the choice of a grow room heater?

    Many factors affect the heater used in a grow tent. Some of them include:

    • Type of Heater
    • Portability
    • Size of the room
    • Power Consumption
    • Safety
    • Ease of Use
    Where should I place the heater in my grow room?

    The choice of the heater’s location depends on the amount of heat it generates, the amount of heat your plants need, the size of the tent, etc.

    If your grow room is small, say, for example, it measures 6×6, the heat from the heater might be too much for the plants. Hence, placing it outside is the ideal choice.

    However, if your grow tent is bigger, say, for example, 10×10, the size allows you to place the heater inside the tent.

    Since some of these heaters come with stands and even suspenders, you do not have to take up valuable floor space. You should note that your plants should be some distance away from the heater. If this is not done, the proximity to such heat can make the plants shrivel up and die.

    What should I look out for in a heater?

    When the heater is in use, there are precautions you have to take. For instance, you need to keep humidity in check. If you are not observant, your heater can remove the moisture in the room and “choke” your plants.

    As you want to be economical and careful, you should note the amount of power the heater consumes. Furthermore, you should ensure that your circuits can handle the extra load from the heater. If they cannot, then be prepared for blown circuits in the end.

    When should I heat the grow tent?

    In normal weather, you can do this in the evening when the temperature cools down. However, in winter, you need to do it almost round the clock.

    Do grow tent heaters have bad effects?

    NOT IF YOU USE IT RIGHT. These heaters are made to improve plant growth.

    Conclusion

    There are many heaters available on the market, which can make choosing the right one difficult. We hope that you will use the information contained in this article to choose the best grow tent heaters for your plants.
