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
If you’re still using high-pressure sodium or high-pressure mercury vapor grow lights, it’s time to make the transition to LED. Or, at the absolute least, to the Children’s Miracle Hospital. Do not even consider using HPS or MH if you are just starting out in the business world. LED grow lights (and CMH grow lights as well) are simply superior than older HPS or MH grow lights in every aspect (except initial cost, though even that is fairly close these days). LED lights consume less electricity to produce the same amount of light, and they generate less heat.
Furthermore, you will not be need to update bulbs every two to three years.
If you want to save time and money, opt for the HLG grow lights, which are manufactured in the United States.
Spider Farmer is unquestionably the greatest, but if your budget is even more restricted, theViparspectra Pro Series lights are a good alternative.
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
The grow tent should always be equipped with at least one oscillating fan, regardless of whether or not you are ventilation your grow room. In large tents, you’ll need a number of these. Find out which fans are the most effective for grow tents in this article. These fans keep the air flowing over the plants at a constant rate. Not only does this assist to keep things cold, but it also helps to prevent the growth of mold.
This is especially crucial during the early phases of the grow when you want to increase the humidity levels in the grow tent, as well as during the latter stages when huge buds and fan leaves obstruct air movement in the grow tent.
Put A Swamp Cooler In The Tent
Swamp coolers chill the air by evaporating the water contained within them. For this reason, they are often referred to as evaporative coolers. They are more efficient at chilling air than other types of coolers (such as regular air conditioners), but they also add moisture to the air they are used to cool. If you need to boost humidity, a swamp cooler is a fantastic tool. However, if your grow environment is already too humid (or just perfect), you should avoid using a swamp cooler. Instead, use a conventional air conditioner to cool down.
Put An Air Conditioner In The Tent
Air is cooled by swamp coolers because water evaporates and cools the air around it. Because of this, they are often referred to as evaporative coolers. They are more efficient at chilling air than other types of coolers (such as regular air conditioners), but they also add moisture to the air they are used to cooling. The usage of a swamp cooler is highly recommended if you need to boost humidity in your growing environment; however, if your growing environment is already too humid (or just perfect), you should avoid using one.
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. If you’re a grower, we’re willing to bet you’ll be unable to stop scrolling until the very end. 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 can 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 opportunities are utilized to their full potential. And this will eventually result in a reduction in heat accumulation and a decrease in temperature. Another concern that can be addressed from this position is the maintenance of proper airflow. You can improve ventilation by following a few simple guidelines that can be implemented with whatever available resources you may have at your disposal.
- 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 required. Finally, you must make certain that these venting chances are utilized to their full potential. The heat accumulation and temperature increase will gradually be reduced as a result of this. Another challenge that may be addressed from this position is providing enough ventilation. You can increase ventilation by following a few simple guidelines that may be implemented with whatever resources are available to you. Listed below is everything you need to know:
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
It is possible that you have a definite belief that there is a direct relationship between humidity and temperature if you have done your research. Particularly when dealing with a limited space such as a grow tent, the connection becomes more clear. The general rule of thumb is that the lower the humidity, the higher the temperature will be in any given situation. In the same way, vice versa. As a result, if the humidity is below a certain level, it is possible that heat and temperature accumulation may occur within the growing environment.
Increasing the humidity levels in the grow tent if the humidity levels are lower than that will benefit both the plants and the overall temperature condition in the grow tent.
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.
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. When we talk about fans, we are referring to two different sorts of fans:
- 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.
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.

- So, make yourself a cup of coffee and set aside 10 minutes to read over the entire essay.
- Let’s cruise through the entire composition and meet up at the conclusion once more.
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
Heat is generated by lights in a grow room to a significant degree. Some goods, on the other hand, give off heat that spreads throughout the area. Bulb ballasts, large pumps, and other such items are examples of this.
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.
AC units, on the other hand, are likely to consume a significant amount of energy. As a result, you can’t always rely on your air conditioner to do all of the cooling duties. Continue reading this article to learn about more cost-effective options.
Take Care of The Ventilation
The ventilation or air exchange of a grow room is the most essential environmental aspect that has a direct impact on the temperature of the growing environment. Because the heat created within will simply build if there is insufficient air flow, the temperature will continue to rise indefinitely without effective ventilation. The next question that comes to mind is, “What does it need to have appropriate ventilation? “. To put it succinctly, it implies that the plants should receive the same amount of airflow as’mother nature’ would provide if they were cultivated outside.
- There are two types of fans that may be used to complete the task: oscillating fans and extractor fans.
- While the other fan circulates old air out of the room and brings in fresh air from the outside.
- You’ve picked the optimal combination based on the size of your grow area, the quantity of plants you want to produce, and other environmental factors.
- Begin by locating the input ductwork in the coolest available location nearby.
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
A continuous location for the lighting sources may result in hot spots and uneven illumination across the room. Put yourself in the driver’s seat of a moving truck. Using a curved rail, they may carry the lights back and forth or in a circle. As a result, the light dispersion across a large region becomes more consistent, which is beneficial. The amount of hot spots and problems caused by canopy overgrowth are reduced as well. First and foremost, it contributes to lessening plant stress caused by excessive heat exposure.
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.
Solution? Reducing the nutrient content by around 20% to 40% by adding clean water to the mixture is possible. Additionally, air movement in the reservoir may be of assistance.
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
Having a low amount of humidity is another significant factor in the temperature of your grow room. It is well known that high temperatures are caused by low humidity. The same goes for the other direction. Increase the relative humidity of the grow space if you want to beat with a high temp. In turn, this will aid in the transpiration of moisture via the leaves, resulting in a cooling effect. How big of an increase would be required now? In that case, what is the best way to keep your grow tent cool?
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
As you are aware, there are three types of air conditioners available: portable, split, and window. While these three types differ in terms of size, application, functionality, and, of course, price, they are all useful. If you’re utilizing a grow tent of the size of a 2X4 or 5X5, a portable air conditioner that fits your budget will suffice. Split air conditioners, on the other hand, are the greatest choice for growing in a bigger space, such as a grow room. For the third option, we do not believe that a window air conditioner would be the most cost-effective option for a developing room.
You can, however, have a look at our in-depth examination of the many types of grow room air conditioners. For the time being, here are our top selections for air conditioning systems for growth rooms and tents:
|Midea Portable Conditioner||12,000 BTU||300 Sq.ft.||See Price|
|Whynter ARC-14S||14,000 BTU||500 sq ft||See Price|
|LG LP0817WSR||8,000 BTU||150 sq ft||See Price|
The unusual piece of equipment has evolved into a one-stop solution for many growers that need to regulate the environment of their grow room in an efficient manner. It’s essentially an air conditioner that also includes a CO2 feeder, dehumidifier, and air filter. Split type and water-cooled type are the two sorts of these computers available. The second option is more likely to be used by growers. The main feature of this unit is that it automatically cools and dehumidifies the room based on the temperature and humidity of the environment.
In case you’re interested, here’s a link to the Opticlimate Pro 3.
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 can 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.

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
Air conditioners are an easy and convenient solution to keep your grow tent cool. One tiny air conditioner can be used in a small tent if the space is limited. Alternatively, it may be placed outside, next to your little grow tent, or in the same room where your tent was originally located. A larger tent, on the other hand, will necessitate the use of a more powerful air conditioner.
If you’re growing on a large scale, the sole disadvantage is that using an air conditioner may result in higher power use. However, employing an air conditioner to chill your grow tent is one of the most effective and efficient strategies you can do.
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.
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. Image courtesy of Gray Rhee and Pixabay.
2. Proper Ventilation
Check to see that the fan linked to the exhaust is large enough to handle the size of the grow tent and that it is operating at optimal efficiency. A fan that is either too tiny or just does not perform properly may cause air to stagnate rather rapidly, resulting in temperature variations and other problems. In addition to exhaust fans, intake fans should be examined since they normally have an easier time dealing with problems than exhaust fans.
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
Heat is removed from the light rig using either water or air, and the heat is extracted by a pump or fan, depending on the kind of system. In a room where ventilation is already rather strong, air-cooled rigs can be moderately successful; nevertheless, they are only modestly beneficial in a place that is continually overheated. Using a fan inserted in the light’s reflector, they operate by continuously pushing air over the surface of the light, transferring heat in the process.
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
Because it requires continual refilling of ice during the grow if utilized as the primary source of cooling, we recommend it just as a temporary option while looking for a better one. Make Your Own Icebox Intake System Using This Simple Technique In this design, an intake line is routed via a cooler that has been modified to include holes allowing ducting to pass through it.
Continue to load the cooler with ice, and the intake fan will automatically turn on soon there is enough ice in the cooler. However, rather than being considered a permanent solution, it should be viewed as one that buys time. Pixabay images courtesy of micripper

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.
9 Methods To Lower Temperature In Your Grow Tent (2022)
Maintaining an appropriate growth environment in your grow area is one of the most difficult aspects of growing cannabis indoors, and it may be quite difficult. It’s also the most critical factor to consider. It’s no surprise that I receive a large number of inquiries from farmers seeking assistance in decreasing their grow tent temperatures. If you want to reduce the temperature of your grow tent, there are numerous practical methods you may do. For example, moving your grow tent to a cooler part of your home, switching from an HPS to an LED grow light, and ensuring that your grow tent fan is pushing air out the window rather than into the room where your tent is placed are all good ideas.
Just to be clear, the best temperature range for growing cannabis is between 70 and 80 degrees Fahrenheit, or 21 and 27 degrees Celsius.
It is critical to maintain consistent temperatures in your grow tent in order to minimize plant stress.
To begin, I’ll discuss the most practical techniques of decreasing grow tent temperature, and then I’ll discuss the less practical ones:
Method 1: Relocate Your Grow Tent
Growth cannabis indoors can be quite difficult, and maintaining an appropriate growing environment in your grow area is one of the most difficult aspects of it. The fact that it is the most crucial factor is also significant. Perhaps it’s no surprise that I receive so many inquiries from farmers seeking assistance in decreasing the temperature of their grow tents. If you want to reduce the temperature of your grow tent, you may take a few practical actions. For example, moving your grow tent to a cooler part of your home, switching from an HPS to an LED grow light, and ensuring that your grow tent fan is pushing air out the window rather than into the room where your tent is placed are all good options.
Just to be clear, the best temperature range for growing cannabis is between 70 and 80 degrees Fahrenheit, or 21 to 27 degrees Celsius.
Plant stress may be avoided by maintaining consistent temperatures in your grow tent. When temperatures fluctuate often, crop yields are lowered. To begin, I’ll discuss the most practical techniques of decreasing grow tent temperature, and then I’ll discuss the less practical alternatives.
Method 2: Route Grow Tent Ducting Out The Window:
The objective of the inline fan should not be defeated by merely blowing the air from your grow tent into the room where your grow tent is placed; otherwise, the fan will be ineffective. In order to counteract the negative pressure caused by your grow tent’s inline fan, you must draw air from the room where you have set up your tent and draw it back into it through your grow tent’s inline fan. You should take your ducting, or purchase extra ducting if required, and direct it out a nearby window to exhaust the heat.
Method 3: Turn on Your Air Conditioner:
Maintain a cool environment in the room where your grow tent is positioned. The most straightforward method of accomplishing this is to open a window during the colder months or to get a portable air conditioner to keep the area cool. Consider putting the portable air conditioner inside the grow tent if that isn’t enough to alleviate the problem. When the inline fan blows out hot air and generates negative air pressure in your grow tent, the air in this chamber is drawn back into your tent, causing the air to be drawn back into your tent.
Keep in mind that if the temperature inside your tent is 85 degrees Fahrenheit and the temperature of the external air being drawn into the tent is only 80 degrees Fahrenheit, the temperature differential will not be sufficient to cool the tent down.
Method 4: Add CO2 to Your Grow Tent
Maintain a comfortable temperature in the room where your grow tent is situated. In the colder months, opening a window or getting a portable air conditioner to keep the space cool is the most straightforward method of accomplishing this goal. Consider putting the portable air conditioner inside the grow tent if that isn’t enough to keep the temperature down. When the inline fan pushes out hot air and generates negative air pressure in your grow tent, the air in this area is drawn back into your tent, causing it to become suffocating.
You should keep in mind that if the temperature inside your tent is 85 degrees Fahrenheit and the temperature of the external air being drawn into the tent is only 80 degrees Fahrenheit, the temperature differential will not be sufficient to adequately chill your tent.
Method 5: Make an Ice Box (with ice or dry ice):
This strategy will need a little ingenuity, but it is effective if you are willing to put out the effort. Because dry ice does not require replacement as frequently as wet ice, it will require far less maintenance.
Using dry ice to reduce the temperature of a grow tent has the added benefit of creating CO2, which helps plants to survive at greater temperatures than normal (85 to 90 degrees Fahrenheit) as a result! What you’ll need is the following:
- Cold storage chest
- Ice or Dry Ice
- Oscillating fan
How to assemble: This may be as simple as putting your ice in a container or chest and directing an oscillating fan at it to cool it down. To be more imaginative, you may opt to seal the chest and cut a hole on either side of it, placing a fan in one hole and allowing air to escape through the other. A word about dry ice and carbon dioxide: CO2 is present at a concentration of 400 parts per million (ppm) in fresh air. Most gardeners agree that a CO2 concentration of 1,200 to 2,000 parts per million (ppm) is optimal for considerably improved plant yields.
- Concentrations more than 2,000 parts per million (ppm) can be harmful.
- Due to the fact that CO2 is heavier than air, you should have an oscillating fan operating to circulate the gas around the camp.
- When Using Regular Ice:If you don’t want to use dry ice, you might try making salt-ice instead.
- The use of salt allows the ice to remain frozen for a longer period of time.
Method 6: Make Sure Your Inline Fan is Strong Enough:
The inline fan in your grow tent is an excellent initial step in the process of eliminating heat from the tent. By clicking here, you can read my post on how to choose the proper size fan for your grow tent. Generally speaking, your inline fan should be replenishing the air in your grow tent once per minute, according to the rule of thumb. You must also consider the lower fan power caused by bends in the ducting as well as the use of a carbon filter when designing your system. You might want to consider increasing the speed of your inline fan or purchasing a more powerful one if your current one isn’t powerful enough.
Method 7: Switch from HPS / HID Grow Lights to LED Grow Lights:
HPS and CMH grow lights generate a lot of heat. Consider upgrading to LED grow lights, which operate at a lower temperature and make maintaining the temperature of your grow tent easier. My time has been spent studying and updating a current list of the finest LED grow lights available, so please have a look at it if you are considering making the move to LEDs.
Method 8: Place Your Grow Light Drivers Outside Your Grow Tent:
The Mars Hydro TS-3000 (4×4 ft) and the TSL-2000 (2×4 ft) versions of LED grow lights, for example, feature replaceable drivers if you decide to make the conversion from HPS to LED grow lights. This is a significant advantage for growers that have difficulty decreasing the temperature of their grow tents.
Method 9: Relocate Hydroponic Equipment Outside Your Grow Tent:
If you’re growing hydroponically, you may be employing pumps, filters, reservoir chillers, or other electrical equipment that may be moved with the use of an extension cable or expanded pipes to accommodate your growth needs. Consider relocating as much of it as possible outside to help lower the warmth inside the grow tent. As you can see, there is no one perfect way for decreasing the temperature of a grow tent. There are several options. You may find one way to be more convenient or effective than another for you.
The dry ice approach is my personal favourite if the simpler ways don’t work for you.
While it may not be the simplest approach to use, I believe it is one of the most successful when it comes to raising the temperature of your grow tent environment to a comfortable range.
