How To Cool A Grow Tent Without Wasting Tons Of Money
When it comes to growing cannabis indoors, heat is the one issue that almost every grower has to deal with. Growing marijuana in a small space, along with the heat created by grow lights and other equipment during the summer months, causes temperatures to rise much over what is considered safe for marijuana plants. If you want your plants to survive until harvest time, you must take action to combat the heat. Fortunately, there is a great deal you can do. For decades, growers have been able to successfully deal with heat-related issues.
Continue reading to find the most effective methods for keeping your grow tent cool, even during the warmest summer days.
How To Cool A Grow Tent
Based on your location, the temperature in which you reside, the sort of grow lights you are using, and a variety of other circumstances, you may have a significant heat problem or a very minor one. All of the ways for cooling your grow tent that are discussed here can make a significant impact in the temperature inside. However, most of them will not be sufficient on their own, unless you are dealing with a very little quantity of extra heat. If you’re dealing with a more complicated topic, you’ll need to mix numerous approaches.
More information may be found in “Do Grow Tents Prevent a Helicopter From Detecting Heat?”.
Switch To LED Grow Lights
Depending on where you reside, the sort of grow lights you are using, and a variety of other circumstances, you may have a significant heat problem or a relatively minor one with your marijuana plants. It is possible to make a difference with any of the cooling options for your grow tent described below. Unless you have a little quantity of extra heat to deal with, however, most of them will not be sufficient on their own. A larger challenge will necessitate the use of a number of different approaches.
If you want to know more about this, read “Do Grow Tents Prevent A Helicopter From Detecting Heat?” Having said that, even if you do not have a significant heat problem, combining numerous solutions will always be the most effective, and this is exactly what we propose.
Put Ballasts Or Drivers Outside The Grow Tent
If you are using high-intensity discharge (HID) lights and want to use them indefinitely, you may limit their heat output within the grow tent by placing their ballasts outside the tent. Because the ballasts generate a significant amount of heat on their own, placing them outside can be beneficial. You may also dim the ballast in order to lower the output of the lights as well as the heat produced by the ballast in itself. Even with LED grow lights, this might be a viable solution in some situations.
The Quantum fixtures and the Spyder type fixtures are both capable of doing so.
If you have an LED grow light with an external driver, you should be able to remove it from the fixture and set it outside the grow tent without difficulty. A tiny grow tent without ventilation, in particular, can have a significant influence on the amount of heat generated within the grow tent.
Cycle Air In And Out Of The Tent
At the absolute least, you’ll want an exhaust fan and some ducting in order to do this. In addition, a charcoal filter will almost certainly be required. Furthermore, if you are utilizing a large grow tent, you will want an intake fan as well as a ventilation fan. Read our post on how to determine the size of fan you require. In order for my grow tent to function properly, I need to know what size fan I’ll need. Make use of the exhaust fan to remove the air from the grow tent. You could just vent it into the room, but it would cause the room to heat up, and you’d end up with an issue that was identical to the previous one.
- However, even in this case, it is preferable to use the ductwork to direct the air out a window or into the attic.
- A simple system for producing marijuana indoors.
- You should probably use a carbon filter to eliminate the stench from this air before releasing it into the surrounding environment to avoid spreading it further.
- Although you may place this carbon filter outside of the grow tent to save room, it is normally preferable to do so if at all feasible within the tent.
- Because cold air tends to settle towards the bottom of the tent, the intake should be located near the bottom of the tent.
- In order to draw fresh air into a larger grow tent, the exhaust fan will need to be very powerful, which means you’ll need an intake fan that can keep up with the exhaust fan in order to draw fresh air into the tent.
- Maintain a comfortable temperature in the room outside the tent.
- It is also possible to install an air conditioner directly in the tent (see below).
- The following are some considerations to keep in mind when doing ducting.
- Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the aperture at the end of the duct.
- Consider installing a screen over each entrance to keep them out completely.
Run An Oscillating Fan In The Grow Tent
A minimum of an exhaust fan and ducting will be required to accomplish this. A carbon filter will very certainly be required as well. An intake fan will be required if you’re working with a large grow tent. Read our post for more information on determining the appropriate size of fan for your needs. In order to properly ventilate my grow tent, I must first determine the size of the fan required. Pulling air out of the grow tent using the exhaust fan is a required. You could just vent it into the room, but it would cause the room to heat up, and you’d end up with an issue that was identical to the one you were experiencing.
- If you must use ducting, it is preferable to vent the air out a window or into the attic rather than via a window.
- Inside marijuana cultivation at its most basic.
- In order to avoid spreading the smell of this air around the globe, you should definitely use a carbon filter to eliminate it.
- However, it is normally preferable to use this carbon filter within the grow tent in order to preserve space, unless it is absolutely necessary to do so.
- In order to keep chilly air at bay, it’s best to place the intake near the ground.
- As mentioned above, the exhaust fan for a larger grow tent will need to be quite powerful, so you’ll need an intake fan that can keep up with the exhaust fan in order to draw new air into the tent.
- Maintain a cool temperature in the space outside the tent.
- It is also possible to install an air conditioner directly in the tent itself (see below).
- The following are some things to keep in mind when doing duct work.
- Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the opening at the end of the run.
Pests can also enter through the ducting or the intake vent, in addition to being attracted to the light. Consider installing screens over each opening to keep them out.
Put A Swamp Cooler In The Tent
At the absolute least, you’ll need an exhaust fan and some ducting to do this. You’ll also most likely require a charcoal filter. Furthermore, if you are utilizing a large grow tent, you will want an input fan as well. Check out our post on determining the size of fan you require. In order to properly ventilate my grow tent, I need to know the size of the fan. To remove air from the grow tent, turn on the exhaust fan. You could simply vent it into the room, but it would cause the room to heat up, and you’d end up with a similar problem in the end.
- Even in that case, it’s preferable to use the ductwork to direct the air out a window or into the attic.
- A straightforward system for cultivating cannabis inside.
- You should definitely run this air through a charcoal filter to eliminate the stench before releasing it into the environment.
- Although you may place this carbon filter outside the grow tent to save room, it is normally preferable to do so if at all possible.
- Because cold air tends to settle towards the bottom of the tent, the intake should be near the bottom of the tent.
- The exhaust fan for a large grow tent will need to be pretty powerful, therefore you’ll need an intake fan that can keep up with the exhaust in order to draw fresh air into the tent.
- Maintain a cool temperature in the room outside the tent.
- Alternatively, you may install an air conditioner right inside the tent (see below).
- When ducting, there are a few things to keep in mind.
- Utilize light-proof ducting and make a u-shaped bend at some point in order to ensure that no light enters through the aperture at the end.
- Consider installing a screen over each entrance to keep them out.
Put An Air Conditioner In The Tent
This is the quickest method of bringing the temperature of the air within your grow tent down. However, it is only something you would want in a larger tent because it takes up a lot of room and significantly cools the air.
It also helps to reduce the humidity in the grow tent. An air conditioner in a room outside the tent will usually be sufficient in most situations. As a result, it helps to chill the air outside the tent, which is then drawn inside the tent via the intake.
Run Lights At Night
If you are growing indoors, there is no rule that says your plants must have the same daytime hours as you do throughout the growth season. Their sunlight might be our nighttime, and vice versa. Temperatures are colder at night, which will assist to counteract the heat generated by the lights during the day. Additionally, there may be an extra benefit. Some electrical companies offer cheaper electricity prices throughout the evening and midnight hours, which means you may save a little money as well.
Plants that bloom, such as marijuana, require 12 hours of continuous darkness every single day to thrive.
Move The Grow To The Basement
Heat increases, as we have already established. As a result, the lower levels of your home will be significantly colder than the top levels. If your grow tent is presently placed upstairs or elsewhere, relocating it to the basement will result in a somewhat cooler ambient temperature, which will make it simpler to keep your tent cool while it is being used.
Cooling A Grow Tent: Final Thoughts
Maintaining a cool growing environment in order to enhance development and output is likely the most difficult challenge marijuana farmers must overcome. There are a plethora of things you can do, to be sure, but they all need time, effort, and money. It’s simply a matter of viewing it as a necessary component of indoor growing operations. Accept the fact that you will need to acquire fans, ducting, filters, and possibly even air conditioning units in order to complete your project. Additionally, you should consider using LED grow lights rather than obsolete HPS or MH lights (we still recommend CMH, though we prefer a quality LED).
How to Cool A Grow Tent? – 10 Actionable Ways to Take
What do you think the months of June through August are like for you? We’d say it’s scorching. And when given the opportunity, we run under the air conditioners or at the very least beneath the fans to cool ourselves off. If that’s the case with ourselves, why shouldn’t it be the same with the plants? We’re talking about an agrow tent in particular, to whom you’re pretended to be ‘Mother Nature’ from every angle possible. Consequently, if you’re concerned about how to cool a grow tent that’s becoming excessively hot, it’s quite OK to choose that route.
Listed below are five strategies for keeping the temperature of a grow tent under control.
Let’s get this party started-
What Turns a Grow Tent Hot?
Before we can learn how to cool down a grow room, we must first understand what is causing the abrupt increase in temperature in the space. Throughout this section, we’ll refer to each of the probable explanations by their proper names. Let’s have a look-
- If the ventilation system fails, the heat generated within the tent is trapped within the tent itself. What is the obvious ramification of this? No doubt about it, there’s heat trapped within the tent, boosting the temperature
- It’s likely that the tent’s HVAC system isn’t performing up to pace due to the excessive heat in the surrounding environment. The higher the temperature outside, the greater the amount of work the cooling system needs to do. Otherwise, the temperature and heat would soar to dangerous levels. The presence of too many heat sources within the grow tent region and not enough cooling agents to neutralize them is another probable explanation for the problem. The absence of adequate insulation around the tent’s outside is another potential source of heat loss that we would need to solve. And that is most likely to occur in summer climatic zones
Have you acknowledged each and every one of them?
Let’s have a look at some of the various solutions for getting them sorted out for a good purpose.
Ways to Cool A Grow Tent- Without Products
During this first section of the solutions, we’ll speak about several improvised methods of cooling down a grow tent. These will not be associated with the purchase of any items or the incurring of any costs in any way. All of the action will be focused on improvisation, optimization, and correction. Let’s have a look at it-
Way 1: Get the Best Out of the Ventilation Scopes
Grow tent kits available on the market are equipped with vent holes through which you may insert carbon filters, ducting into and out of the tent, and anything else that may be necessary. On that note, you must make certain that these venting chances are utilized to their full potential. And this will eventually result in a reduction in heat accumulation and a decrease in temperature. Another challenge that may be addressed from this position is the maintenance of appropriate airflow. You may increase ventilation by following a few simple guidelines that can be implemented with any available resources you may have at your disposal.
- Reposition the clip-on or stand fans throughout the grow space to better suit their needs. Additionally, if they offer to modify the speeds, you can do so. Relocate the location of the input duct opening to the coolest suitable location in the immediate vicinity. When this is done, cold air will be drawn into the tent, resulting in a dramatic reduction in the temperature within. If they have not previously done so, they should consider adequately closing the vent openings.
Way 2: Diminish the Heat Sources as much as Possible
The most basic approach to cooling down a grow tent is to utilize goods that chill the air. However, if we believe contrary, we may achieve the same result by reducing the amount of heat that is produced within a tolerable range. And it works just as well as the first method. When it comes to naming heat sources in a grow system, there are just a handful that come to mind. Let’s have a look at the list:
- The lights (1 source of heat)
- Space heaters
- Motor-driven devices
- Soil that carries heat inside it
- And other sources of heat
Now, let’s speak about the grow lights first, because they are the primary contributors of pollution in this environment. In the first place, lights must be kept at a safe distance from the plants’ roots. After that, you can switch to using air-cooled light hoods instead of ordinary light hoods. Because these hoods take care of the hot air that is generated by the lights and prevent it from entering the grow area. Aside from these two points, there are a couple of small details that you should be aware of.
Additionally, you must employ automatic controllers to turn off the lights when they are not required.
When it comes to other sources of heat, you may use the same tactics that we recommended for lighting.
Way 3: Optimize the Ducting
This is something that many growers ignore, and as a result, they find themselves in an unexpectedly heated growing environment. In the ducting, this is the result of an excessive amount of bending. The following is a straightforward calculation: for every 90-degree turn within the duct, the fan must work 5 percent harder than it would normally be required to accomplish. This means that your fans will be less effective the more twists and turns there are in your ducting. Result? Poor air transmission and an increase in the temperature.
Moreover, this is true for both the intake and the exhaust ducting. Additional ducting and increased length can be added if necessary to meet your requirements. However, while doing so, you must make certain that the bending is maintained to a bare minimum.
Way 4: Avoid Low Humidity in the Grow Tent
Because many gardeners fail to consider this point, they find themselves in the midst of an unexpectedly warm growing environment. In the ducting, this is the result of an excessive amount of bend. Using a straightforward calculation, the fan must work 5 percent harder than it would otherwise have to in order to complete every 90-degree rotation within the ductwork. This means that your fans will be less efficient the more twists and turns there are in your ductwork. Result? Reduced air flow and a consequent rise in internal temperatures Consequently, while your ducting is being transported from another location to your grow room, ensure that it is as straight as possible.
Additional ducting and increased length can be used if necessary, if necessary.
Way 5: Reposition the Grow Tent As Per the Exterior
As long as the heat difficulties are taken into consideration, the location of the grow tent within the house is quite vital to the success of the operation. Typically, growers like to store them in secluded areas such as the garage, cupboards, or other similar locations. However, in the event that you are not one of them, the following are some pointers. Place the grow tent away from the south-facing wall of your home. This will help to keep the bugs out. This is likely to prompt thoughts about how to construct a perimeter around the grow tent.
The heat of the sun is transferred to the tent through the nearby air, causing the tent to inhale hot air.
Rest confident that you will be able to take care of the ventilation on your own.
Ways to Cool A Grow Tent – With Products
It is a well-known truth that air conditioners are intended to reduce the temperature of a room. And, in a small and curved environment such as a grow tent, this is far superior than any other option available to you. Consequently, if you want to invest money after cooling down your tent, compact ac units are the ones you should consider purchasing later. The size of your grow space, on the other hand, will determine which of the following alternatives you can use: Even though little air conditioners are less powerful, they are capable of cooling tiny grow tents such as 4×4, 4×5, 5×6, 6×8, and even 10×10.
As a result, while it cannot be used in the tent, it may be utilized in other situations.
They are effective, self-controlling, and have a lengthy shelf life to look forward to. However, as you may imagine, they come at a significant financial expense. Split Air Conditioning Units that We Recommend
Way 2: Use Fans
Because you are already familiar with the construction of an agrow tent, we assume that you have already occupied the fan(s) in it. However, given that the current scenario suggests that these fans are not adequately cooling the tent, we believe there is room for innovation. Replacement of the old fans with new and more efficient ones is what we’re talking about! Finding the proper size and kind of fan is always important when it comes to maintaining a healthy temperature for your growing plants.
- Inline fans: Fans that are built into the ductwork and are responsible for both the air intake and the air exhaust
- Oscillating fans: These fans are either openly attached to the grow tent wall or stand on the floor to ensure that the grow tent’s interior air circulation is properly maintained.
As a result, identify the appropriate size for both of these kinds and place them in an appropriate location. Location of fans is also significant since, if they are put in the wrong location, they will just circulate old, hot air inside the air instead of fostering new and cold breezes around the room. Inline fans that we recommend are as follows: Oscillating fans that we recommend are listed below. Sales promotionAir King Clip Fan, 6 inch (white). 6-inch commercial-grade 2-speed fan with a spring-loaded clip-on construction; 1/300-horsepower motor that is permanently oiled; polypropylene blades.
Way 3: Use Water Chillers
If you discover that ac units are prohibitively pricey for the amount of indoor gardening you do, there is a finer and more economical alternative available. And they are referred to as water chillers. Chillers for water are electric devices that absorb wet vapors while leaving the cold and cooled ones in their wake. There are two types of chillers: water-cooled chillers and air-cooled chillers. Water-cooled chillers are more common. Despite the fact that the latter is less expensive, it is less effective for grow tents larger than 44.
These devices are equipped with a water reservoir to keep the water contained and an evaporating mechanism to reduce the temperature of the surrounding environment.
As you have seen previously, insufficient humidity is one of the probable causes of the heating of grow tents.
However, in the best-case situation, we recommend that you use a decent humidifier to deal with any humidity issues you may be experiencing.
Way 4: Control the Climate
When it comes to heat management in a grow tent, you may make considerable strides forward by regulating the environmental factors on your end. By doing so, we’re tackling issues such as-
- Grow lights, inline fans, oscillating fans, air conditioners, humidifiers, dehumidifiers, and any other electric HVAC equipment are all recommended.
Having the ability to apply some preset regulating directives about when they should turn on and when they should remain turned off will be quite beneficial. This is particularly effective in preventing the intrusion of unnecessary heat into the home. In addition, if you maintain tight control over the grow tent environment, there are a number of health benefits for the plants as a result.
The controllers are available on the market in a variety of configurations. There are controllers that work alone, and there are controllers that work in a 360-degree environment. Listed below is a selection of our top-recommended products from both categories:
Way 5: Use An Ice Box
Think about it: what could be any more inexpensive than a water-based chiller? Yes, you read it correctly; the icebox is the culprit. It is, in fact, a box of ice, just as the name implies. If you don’t want to use a box, you may use a bucket and transform it into a homemade icebox. These are not things that are available for purchase at a store. However, if you’re interested, you may create one yourself by following a few easy steps.
What is even more economical than a water-based chiller, in your opinion? This does indeed refer to the icebox, which you have correctly identified. It is, in fact, a box of ice, as the name suggests. It’s also possible to use a bucket instead of a box to make your own icebox at home. It is impossible to purchase these products at a store. It is possible, though, to create one yourself by following a few basic procedures.

Reasons for A Rise inGrow Room Temperature
It’s fine if you haven’t finished building your grow room yet. However, if you already have one, you may be experiencing severe discomfort as a result of the high temperature. Consider the following causes for the situation before continuing further: a.
Take a stroll in the outside garden or the neighborhood park. Is there anything else that mother nature provides them, apart than sunlight, that they need? Yes, you are correct; that is the natural air movement. In the case of indoor cultivation, this is referred to as ventilation. Plants suffer from a variety of problems when they do not have adequate ventilation. And the first of these is a greater internal temperature.
Too Many Heat Producers
The most significant source of heat in a grow room is the lighting.
However, there are some objects that produce heat that circulates throughout the area. Examples include light ballasts, large pumps, and other such items.
Not-so-Insulated Location of the Grow Tent
For the past two years, I’ve worked as a grower. And, right from the start, I started growing plants in my basement. Growing in such a well-insulated space allowed me to get temperatures that were at least 5°F lower than those obtained with the same arrangement planted anyplace else in the home. And when the plants become overheated as a result of one or more of these factors, they begin to exhibit symptoms of stress. As a result, the amount of bloom or fruit produced is minimal. Please read the next sections of the post if you want to learn about some practical strategies to keep your grow room cool in real time.
7 Grow Room Cooling Solutions That Actually Work
When it comes to chilling a restricted place like as your grow room, nothing compares to the effectiveness of an air conditioner. It not only cools the surrounding environment, but it also removes the heat created by equipment such as blowers, generators, pumps, ballasts, and other similar devices. ACs of varying sizes are likely to be utilized by growers. These are sometimes labeled in terms of BTU (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU, 36,000 BTU, 48,000 BTU), and sometimes in terms of weight (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU, 36,000 BTU, 48,000 BTU) (1 Ton, 2 Ton, 3 Ton, 4 Ton).
Take notice that, while many growers employ portable air conditioning units, window air conditioning units, and other similar devices, a ductless mini split system is the most efficient.
As a result, you can’t always rely on your air conditioner to do all of the cooling duties.
Take Care of The Ventilation
When it comes to chilling a restricted place like as your grow room, nothing beats an air conditioner. Besides cooling the atmosphere, it also removes heat created by equipment such as blowers, generators, pumps, ballasts and other similar items of equipment. There will almost certainly be a variety of AC sizes used by growers. The BTU rating (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU, 36,000 BTU, 48,000 BTU) and weight rating (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU) are occasionally used to name them, and the weight rating is often used to mark these as well (1 Ton, 2 Ton, 3 Ton, 4 Ton).
Take notice that, while many growers employ portable air conditioning units, window air conditioning units, and other similar devices, a ductless mini split system is the most effective.
Air conditioners, on the other hand, are likely to use a significant amount of energy to function. It is not always possible to rely on an air conditioning machine to do all of the cooling activities required. Continue reading this post for additional cost-effective alternatives.
Structurize The Grow Room
A tent that is overcrowded is never a good thing. Every tent has a limit to the number of plants that may be accommodated within it. The presence of an excessive number of plants can result in a variety of problems, one of which is high temperatures.
Using Smart Pots
The use of smart pots to house plants in order to assist them cope with heat stress is an excellent solution. These can assist in surge evaporation, which reduces the likelihood of overheating, as well as maintaining the health of the plants by delivering oxygen from the sides. The use of Coco air is another clever pot hack that aids with the cooling of the growing tent. Your plants will be more resistant to the heat as a result of it. There are a number of additional substances that can aid in the battle against heat stress.
Optimize The Lights
Lights are the primary source of the potentially hazardous heat surges. There are a few instances in which lights can behave more like heat sources than they do as lighting sources. The methods are as follows:
- When the plants reach maturity, the lights should be dimmed. Extreme heat generation as a result of low-quality lighting
- There is insufficient airflow between the lights and the plant canopy. Leaving the light on when it isn’t essential (during the day)
Several things may be done to optimize the lights in order to reduce their heat-generating effects, including:
Raise The Lights
Raising the light by 8-10′′ might be used as a temporary remedy to minimize direct heat impacts from lights on your plants.
Install A Light Mover
Some hot spots and uneven lighting across the area might be caused by light sources that are fixed in one location. Consider taking up residence in a motorized mover. Using a curved track, they may convey the lights back and forth or around a corner. As a result, the light dispersion across a large region becomes more uniform, which is advantageous. Additionally, it minimizes the amount of hotspots and the problems associated with canopy overgrowth. First and foremost, it contributes to lessening plant damage caused by excessive heat exposure.
Run Lights At Night
When compared to the daytime, the nighttime temperature is a few degrees colder than the midday temperature. Growers, particularly those who live in hot climates, should avoid making the mistake of turning on lights during the daily hours. Because the temperature has already risen by a few degrees at that point. Rather, turn on the lights at night. It will help to keep the temperature under control. And it’s possible that it will prevent the power bill from skyrocketing. In a manner, you’re saving both energy and money at the same time.
Use Air Cooled Lights
Using air-cooled lights is an excellent technique to keep lights from creating heat and causing problems. In order to exhaust the hot air from the bulbs, they might be linked to the ducting system. The process will be accelerated even further if the insulation is properly installed. If you want to take it a step further, you may go for lights that are water cooled.
They are equipped with a water reservoir and a water pump in order to preserve water. It is possible that a water-cooled light can discern the essence of an air conditioning unit in a grow tent that has been properly sealed.
Ensure Proper Ducting and Insulation
It has been discovered that each extra right-angle bend in the ductwork results in a 5% reduction in fan performance. The same is true if your ductwork is not properly installed. To be fantastic, you must seal every portion of it with an insurance policy that ensures the smallest amount of bends possible. Aside from that, try to avoid as many right angles bends as possible. Ducting is concerned with insulating the airflow within the building. But what about the entire growing area? – Insulating the grow space, on the other hand, is absolutely necessary.
If you’re growing in a region where your growing space isn’t completely enclosed, you’re going to have to deal with regular temperature increases.
- It should not be placed on a south-facing external wall. A grow room should not be located beneath a hot roof. Try a basement or something similar
- It could work.
This is not a straight answer to the cooling issue that you are experiencing in your grow tent. However, this is a lifesaver when your plants are on the verge of being hazardous. And what exactly is it? A rise in temperature will allow the plant roots to absorb more water as a result of over-transpiration, which will result in increased water consumption. And as they’re doing so, the roots are not only absorbing more water, but they’re also absorbing more nutrients. Overconsumption of some nutrients, such as boron, copper, and manganese, increases the likelihood of poisoning even more significantly.
Reducing the nutrient content by around 20% to 40% by adding clean water to the mixture is possible.
Keep Humidity Under Control
Another important factor influencing the temperature of your grow room is the presence of a low degree of humidity. As you are aware, a decrease in humidity results in an increase in temperature. In the same way, vice versa. Increasing the relative humidity of the growing space can help you deal with a high temperature. This will assist plants in exhaling water vapor through their leaves, resulting in a cooling effect. Now, how big of an increase would be required? Or, alternatively, how do you keep your grow tent cool with that?
Products Used in A Grow Room Cooling System
Growing plants inside is a system that has been created. As a result, there is a solution available on the market for virtually any problem you might possibly encounter. A couple more options are available when it comes to cooling as well.
Inline and Oscillating Fans
Every grower understands the need of having a fan in order to manage temperature and ventilation. Even after being aware of this, many make blunders when it comes to selecting the appropriate type and size of grow fans. Oscillating fans and inline fans are the two types of fans that are commonly used in grow rooms. Air circulation around the plants is provided by oscillating fans, whilst inline fans exhaust heated air and draw in fresh air. It is critical, however, to select a fan with the appropriate CFM rating.
The following are some of our suggestions: -– The best inline fan is: Apollo Horticulture 6″ Inch 440 CFM– Best Oscillating Fan (Wall Mount): Hurricane 16″ Wall Mount Fan– Best Oscillating Fan (Standby): WestPointe HP 16″ Stand Fan– Best Oscillating Fan (Standby): WestPointe HP 16″ Stand Fan
Mini AC Units
To keep the temperature and ventilation stable, every grower understands the need of having a fan. Although they are well aware of this, they continue to make mistakes in terms of selecting the appropriate type and size of grow fans. Oscillating fans and inline fans are the two types of fans used in grow rooms. Air circulation around the plants is provided by oscillating fans, whilst inline fans exhaust heated air and draw in fresh air, as seen below. A fan with the appropriate CFM number, on the other hand, is essential.
The following are some of our suggestions.
WestPointe HP 16′′ Stand Fan– Best Oscillating Fan (Wall Mount): Hurricane 16′′ Wall Mount Fan– Best Oscillating Fan (Standby): WestPointe HP 16′′ Stand Fan– Best Oscillating Fan (Standby): WestPointe HP 16′′ Stand Fan– Best Oscillating Fan (Standby): WestPointe HP 16′′ Stand Fan–

Every grower is well aware of the need of having a fan in order to regulate temperature and ventilation. Even after realizing this, individuals continue to make mistakes when it comes to selecting the appropriate type and size of grow fans. Oscillating fans and inline fans are the two types of fans that are commonly used in grow environments. Air circulation around the plants is provided by oscillating fans, whilst inline fans exhaust heated air and draw in fresh air. It is critical, however, to choose a fan with the appropriate CFM rating.
Here are a few of our suggestions.
Chillers have been assigned the task of absorbing the excess heat that accumulates in a growing environment. There are two types of chillers: water-cooled and air-cooled. Water chillers are preferred by most growers, despite the fact that they are more expensive. Hydroponics water chillers have a reservoir that holds water as well as a nutrient solution. This is the heart of the system. The combination of water and nutrient actively contributes to the cooling of the temperature. Once again, water chillers are only suitable for indoor hydroponics.
Evaporative Cooling Systems
Although the nomenclature seems complicated, the procedure that ECS’s follow is rather straightforward. It contains a solution that may release mists into the air, and the mist is intended to be vaporized after being inhaled.
An additional feature is a swamp cooler fan, which pumps air into a moist medium. A result of this combined activity, evaporation occurs, and the temperature of the grow tent environment begins to decrease. One particular model that we advocate is— Evaporative Air Cooler SF-614P from SPT.
If you want to spend the least amount of money possible to keep a small grow tent cold, preparing an icebox yourself is the most effective method. The procedure is really simple, and it is far less expensive than any of the other goods described above. A tutorial for building an icebox in your grow room is available here on our site. These are the goods that cool directly by cooling air to keep the temperature as low as possible. However, there are several additional goods available on the market that, while they do not provide cool air, they are excellent at preventing heat generation.
- The ability to dim the light
- Reflector hood lights
- Plant fertilizers and vitamins
- And smart pots are all included.
It should be noted that using all of these things to manage the temperature in virtually any grow environment is effective. However, the trouble arises when you are unsure of ‘How Big’ or ‘What Kind’ of merchandise you should purchase once you have decided on your budget. This is because, depending on the size of your grow tent, the kind of power provided by each of these devices varies significantly. You should be certain of this if you choose a remedy to deal with the heat problem.
Check If You’re Making These 4 Mistakes Or Not-
- It Should Be Mentioned: Using all of these tools to manage the temperature in virtually every grow room is a successful strategy. It becomes an issue, though, when you are unsure of ‘How Big’ or ‘What Kind’ of merchandise you should purchase with your money. Because the kind and strength of each of these things will vary greatly depending on the size of your grow tent. You should be certain of this before purchasing a device to deal with the heat issue.

How to Cool a Hot Grow Tent (7 Tips & Tricks)
The most recent update was made on January 18, 2022. Grow tents and other confined environments can get unbearably hot throughout the growing season. A light setup and the fact that cannabis plants perspire away all but around 3 percent of the moisture they absorb results in a sauna-like environment in a container. So, what can be done to mitigate the heat generated by a grow tent? There are a variety of strategies to experiment with, including:
The 7 Ways How to Cool a Grow Tent Are:
Starting with a fairly apparent choice, but one that should be noted since some growers may not be aware of how beneficial a small air conditioning unit can be when placed within a grow tent, is a good place to start. A little portable device is all that is required to reduce the temperature down in a small amount of space. Make sure it’s operating continuously, though, because an air conditioner that cycles on and off during the day will significantly increase your electricity cost.

2. Proper Ventilation
Starting with a fairly apparent choice, but one that should be noted since some growers may not be aware of how beneficial a little air conditioning unit can be when placed within a grow tent, is a small air conditioning unit.
In order to lower the temperature down in a small space, a compact portable device is needed. Maintain consistency, though, because an air conditioning unit that cycles on and off throughout the day will significantly increase your electricity cost. Pixabay image courtesy of Gray Rhee.
3. Consider Changing Lights
If the temperature in a grow room is constantly too high, despite the best efforts of the grower to bring it down, the lighting system in the room is most likely too hot for the tent it is housed in. There are a few various possibilities in cooler lighting from which to pick, so it is not a hopeless situation. Pixabay user cannabispromoter contributed this image. Use LED lights as a trick. After decades of unsuccessful attempts to break into the market, LED lighting solutions are just now becoming widely used.
LEDs are an excellent choice for a grow tent for this reason alone, and they should be taken into consideration in situations such as these.

4. Air-Cooled Rigs
These function by removing heat from the light rig using either water or air, and doing so through the use of a pump or a fan. Air-cooled computers are moderately helpful as long as ventilation is already quite strong in the area, but they are only slightly beneficial in a location that is already constantly scorching on a regular basis. These lights operate by continuously blowing air across the surface of the light by means of a fan mounted in its reflector, therefore transferring heat in the process.
5. Water-Cooled Rigs
Though they perform admirably, water-cooled setups tend to be significantly more expensive than the other two alternatives. This is accomplished by the use of a circulator pump that forces cold water through ducting surrounding the lights. The heat is dissipated into the water, which then travels through a chiller before returning to the top and around again. If you have the option, water-cooled setups are an excellent method to keep a grow tent cool when the weather is hot.
6. Icebox Intake
Because it requires continual replenishing of ice during the grow if utilized as the primary source of cooling, we recommend it just as a temporary option while you search for a better answer to your cooling needs. Make Your Own Icebox Intake System using This Trick Essentially, the idea is to route an intake line via a cooler that has been modified to include holes for ducting to pass through. Continue to fill the cooler with ice, and the intake fan will begin to blow cold air anytime there is ice in the cooler.

7. Good Insulation
True, insulation helps to keep heat trapped within a tent, but this isn’t a problem if the tent’s ventilation is up to pace. Insulation, on the other hand, should be viewed as a means of preventing cool air from evaporating. Proper insulation, when used in conjunction with an air conditioner or other cooling gear and enough circulation, is one of the most effective methods of maintaining a steady and cool temperature for plants.
Tents that are exposed to weather factors, such as those that are put outside or in a non-insulated area of a house, such as an attic, are particularly vulnerable to damage from the elements.

Of course, this is not a comprehensive list of the many various ways people have discovered to cool down a grow tent, but it should give you a decent idea of some easy cooling ideas that every grower can put into action. It’s important to remember that cannabis plants prefer a consistent temperature above an optimal temperature. The ability to maintain a steady temperature in a grow tent, rather than having it swing up and down about an optimal temperature, might be beneficial in some situations.

- For a multitude of reasons, grow tents get hot. Examine your current circumstances and compare them to the examples provided above so that you may determine where the problem is.
In the next part, we’ll go through 27 different strategies for dealing with overheated grow tents.
Top 27 Tips On How To Cool a Grow Tent or a Grow Room
During the day, ideal growth temperatures vary from 70 to 80 degrees Fahrenheit, while at night, temperatures range from 65 to 70 degrees Fahrenheit. This is the temperature that you should be attempting to achieve. As many thermometers as feasible should be installed, with one at plant level and another at the top of the tent if at all possible. This will assist you in determining whether or not you have adequate ventilation and will increase air flow.
Tip 2 – Use Air Cooled Grow Lights with Inline Ventilation Systems
Passive ventilation is provided by cutting ventilation apertures into the side of the light housing, which is common in grow lights. Active ventilation, such as inline fans and air ducts, is used by some growers to keep the grow lights cool. Consider switching to grow lights that are air cooled.
Tip 3 – Use Water Cooled Grow Lights
You may use water cooled grow lights in the same way that you would use air cooled grow lights. Using water cooled lights, you can reduce the size of your shadow imprint, which is ideal for usage in grow rooms that use natural sunlight in addition to LED lighting.
Tip 4 – Don’t Grow in the Attic
Attics will be extremely hot, posing a major heat risk. If you have the option of relocating your grow tent to another room or the basement, do so. In this advice, you will attempt to chill the area around the grow tent, which comes into the category of repairs.
Tip 5 – Insulate the Grow Room In Combination with Adding AC
Adding active air conditioning and insulating the grow tent or grow room are two options if you are unable to leave the attic.
Tip 6 – Grow Rooms – Use Light Movers To Move Heat Around Room Evenly
It is possible to use a light rail to move the lights around and spread the heat in a bigger grow area that has uneven or excessive temps.
Tip 7 – Add Hydroponics with Reservoir Chillers
It is possible to use a light rail to move the lights around and spread the heat in a huge grow room that has uneven or excessive temperatures.
Tip 8 – Add Frozen Ice Bottles Daily
Fill some gallon jugs halfway with water and place them in the freezer.
Every day, place them in the grow tent. Every night, put them in the freezer. It requires more effort than an air conditioner, but it is less expensive!
Tip 9 – Check For Bends or Breaks in Ventilation Tubes
Each curve in a ventilation tube can result in a reduction in efficiency of 5 percent or more. Additionally, ensure that the tubes are free of any debris (or dead animals).
Tip 10 – Add a Cooling Humidifier to Increase Relative Humidity
Top-filling cooling humidifiers are less expensive than central air conditioning equipment. The top filling varieties are less difficult to refill and keep in good condition. If you live in a dry location such as Colorado or the desert west, increasing relative humidity might be beneficial to your plants as well.
Tip 11 – Optimize the Lights
Check to see that your lights are operating at their best:
- Is it possible to see through the ventilation apertures on the lights? Are they dangling at a sufficient height from the top of the grow tent to allow for appropriate air circulation? Is the temperature of the lights too high for such a tiny space? Is it possible to convert to cooler LED lights?
Tip 12 – Use LED Lights Instead of Halogen Or Hotter Lamps
Is it possible for you to relocate your smallgrow tent to another room?
Tip 14 – Move the Grow Tent Away from Windows
Could your little grow tent be moved to a different location?
Tip 15 – Block the Windows In Your Grow Tent Room
However, if you are unable to relocate the grow tent away from the windows, blackout curtains should be used in order to block out the light and keep the room cooler overall. You may also open the windows in the evenings to bring in some fresh air.
Tip 16 – Open All the Ventilation Ports
However, if you are unable to relocate the grow tent away from the windows, blackout curtains should be used in order to block out the light and keep the space cool. Additionally, you may open the windows to allow cold air to enter throughout the nighttime hours.
Tip 17 – Add a Commercial Air Conditioning Unit
If you have the necessary funds and room, this is one of the most straightforward solutions. Purchase and install a business air conditioning unit. It’s that simple. It is possible to utilize a huge unit, such as the one seen below, to furnish the entire room. Alternatively, a tiny unit can be placed within the grow tent.
Tip 18 – Install a DIY Air Conditioning Unit
Alternatively, you may construct your own DIY air conditioning machine. These, like the frozen bottles, require daily maintenance, so plan accordingly.
Tip 19 – Use Timers For the Minimum Light Time Needed
Are your lights left on for an excessive amount of time each day? Make use of timers to provide your plants with the exact amount of water they require to stay cool.
Tip 20 – Add a Intake and Exhaust Fans
This is one of the most often seen solutions. Simply move the air in and out of the grow tent in a deliberate manner. It is most effective when both are present to assist in completely circulating air flow within the grow tent.
Tip 21 – Optimize Air Flow – Are Your Fans Too Small?
If you already have air flow installed, it’s possible that it isn’t moving enough air. Spread out many thermometers at the top, bottom, and all about your tent to keep an eye on the temperature. Alternatively, use a single thermometer and take it to each of the places, taking note of the temperature at each.
Tip 22 – Add Oscillating Clip-on Fans To Circulate Air Inside the Tent
This is a tried-and-true method of keeping a tent cool. Check that a tiny oscillating clip-on fan will flow enough air to keep everything cool, as described in the preceding step.
Tip 23 – ADVANCED – Use a Carbon Dioxide Cooling System
Increasing the amount of carbon dioxide in the air provides plants with more of what they require (CO2 and light), as well as helping to chill the area. This is a more complicated strategy since you must continuously check the CO2 parts per million (ppm) levels in order to ensure the health of your plant as well as your own safety. We’ve discovered that a nice $40 air conditioner is a more convenient solution.
Tip 24 – Add Fans to Grow Lights or Use Grow Lights With Working Fans
It is possible to increase the amount of CO2 and light available to plants by adding carbon dioxide to the air.
This can also assist to chill the environment. The CO2 particulate matter (ppm) levels must be monitored for the health of your plant as well as for your own safety with this procedure, which is more advanced. The less expensive choice, we find, is an excellent $40 air conditioner.
Tip 25 – Check That Any Existing AC Units or Exhaust Fans are Working and Clean
This check should be performed at least once a year, better many times a year.
Tip 26 – Check That Any Glass Panels On Your Grow Lights Have Ventilation and That’s It’s Clean and Clear
This should be the case, but it’s wise to double-check everything once a year.
Tip 27 – Operate Grow Lights At Night Instead of the Day
This final method might save you time by eliminating the need to open and close the windows at night and during the daytime. It is most effective if you also use blackout curtains to filter out the light coming in through the windows of the grow tent room.
How To Keep Grow Tent Cool
Heat is a typical problem that indoor gardeners have to deal with. Maintaining the temperature of your grow tents at a comfortable level is critical to ensuring that your plants survive until harvest time. As a result, we will provide you with the finest advice on how to keep your grow tent cool. Fortunately, there are a variety of things you can do to regulate heat and keep your grow tent as cold as possible during the growing season. Consequently, at the conclusion of this essay, you should be able to understand how to maintain a cool grow tent in order to ensure that your plant grows to its maximum potential.
Tips On Cooling Down Grow Tent
It is critical that you maintain your grow tent cold in order to avoid the accumulation of excessive heat. Too much heat can cause your plant to burn, and it can even cause some of your growing equipment to get damaged. Depending on the amount of heat you’re dealing with and the size of your grow tent, you may require one or a combination of approaches to keep your grow tent as cool as possible. As a result, make certain to consider the amount of heat you’re dealing with in order to choose the best method to take in dealing with the scenario.
As a result, the following are some of the most effective suggestions for keeping your grow tent cool:
1.Use an air conditioner
Using an air conditioner to cool your grow tent is a simple and effective method of keeping it cool. If you’re camping in a tiny tent, you may use one little air conditioner to keep the temperature cool. Alternatively, it may be placed outside, adjacent to your little grow tent, or in the same room where your tent was previously located. However, if you’re using a larger tent, you’ll need a larger air conditioner to keep things cool. The main disadvantage is that using an air conditioner may result in higher power use, which is especially true if you’re growing on a large scale.
2.Inline and exhaust fans
When inline and exhaust fans are used in conjunction with each other, you may get another excellent means of cooling your grow room tent. This will cause the air in your tent to circulate in and out.
A grow tent’s inline fan is responsible for bringing in fresh air inside the grow tent, which is how these fans function. In contrast, the exhaust fan takes the interior air, which is often heated, outside of the grow tent to cool it down.
3.Change your grow light to LED
If you’re still experiencing heat issues in your grow tent, you may want to consider changing the type of grow light you’re currently utilizing. A higher level of heat is produced by some grow lights, such as domestic CFL, HID, and HPS lights, among others. It may be necessary to switch to a grow light that produces less heat (such as an LED, fluorescent grow light, or other similar technology). Because they consume less power and are more successful at growing plants, these grow lights will even help you save money on your electricity bill.
4.Use oscillating fans
Make certain that fans are installed inside your grow tent. Even one or two portable oscillating fans can suffice if you’re camping in a tiny tent. But if you have a larger grow tent, you will need numerous oscillating fans to keep the temperature of your grow tents stable. Always remember to include fans in your plans when you’re making the decision to acquire a grow light. The number of fans you need will be determined by the wattage of your grow lamp. Increased grow light wattage necessitates the use of additional fans, and vice versa.
5.Proper ventilation of tents
In general, your grow tent should be properly ventilated, with input and exhaust vents, among other things. Not only that, but your grow tent should also have frequent vents, which may be covered with layers of mesh to allow for better ventilation. Using intake and exhaust fans in conjunction with these vents increases the effectiveness of this system.
6.Proper ventilation for grow lights
Using a grow light with an appropriate vent enables for the passage of cold air over the grow light while it is in operation. We recommend that you always use a grow lamp that has vents on all four sides of the unit. Set up the appropriate fans in the direction of the grow light vent to allow cold air to move across the grow light and into the room.
Final Thoughts On How To Cool Grow Tent
It is possible to circulate cold air across the grow light when it is equipped with the appropriate vent. If possible, use a grow lamp with vents on all four sides, as recommended by our team of experts. Create a path for cold air to move through your growing environment by directing all of your fans toward the grow lamp vents.
