What is the best way to cool a grow tent? The most exclusive cooling solutions available! 18766Views0 Recent publications have addressed particular concerns around chilling grow spaces, and we’ve published a lot of them pieces recently. There are guidelines on how to regulate excessive temperatures, how to chill grow rooms with ice, and other such topics. However, we soon came to the conclusion that there should be an article that covers everything about how to cool a grow tent, as well as the questions that follow.
It should be a one-stop shop article from which every grower would gain in one way or another.
It took a week to do the study, collect every difficulty that growers were experiencing with reference to grow tent cooling, present the most up-to-date solutions to every concern that was discovered, and put the whole thing together.
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
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.
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
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.
It is not always possible to rely on an air conditioning machine to do all of the cooling activities required.
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)
When the plants have reached maturity, lower the lights. Extreme heat generation as a result of using low-quality lighting. Airflow between the lights and the plant canopy is not sufficient. When it is not essential (during the day), keep the light on.
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
Comparing the nighttime and daytime temperatures, the ambient temperature is a few degrees lower at night. Growers, particularly those who live in hot climates, should avoid making the error of leaving lights on throughout the daily hours of operation. The reason for this is that the temperature at that point has already increased by a few of degrees. Use nighttime lighting instead. It will help to maintain a comfortable temperature. And it’s possible that it will prevent the power bill from skyrocketing in price.
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.
Location on a south-facing outside wall is not recommended. A grow room should not be located beneath a hot roof. Try a basement or anything comparable; it should work.
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
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.
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. Models that we suggest include: JBJ Aquarium Arctica Titanium Chiller–Hydrofarm Active Aqua Chiller JBJ Aquarium Arctica Titanium Chiller
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-
- Dimensions of the exhaust hole and ducting are not identical
- Too many bends in the ducting
- Daytime running lights
- And an excessive amount of space above the lights

The Climate of Your Grow Tent
The optimum environment inside your grow tent is dependent on a variety of parameters, which are discussed more below. For starters, the actual climate of the city and state in which you reside has a significant influence on all of the living things that exist in that particular region of land. You must modify the environment in which your plants are growing in order for it to correspond to the actual environment in which you and your family are all living.
What is the Perfect Grow Tent Temp?
When it comes to plant growth, cannabis is the Goldilocks of them all. Extremely high temperatures are not to their liking. These plants, on the other hand, are not fond of cold temperatures. As a result, you should avoid temperatures below 60 degrees Fahrenheit and temperatures beyond 80 to 85 degrees Fahrenheit. Basically, go with your gut feeling. If it appears that the temperature is either too hot or too cold for the plants, it most likely is. Consider how you feel in the space, and keep an eye on the plants as you go about.
- The Thrive Leads Shortcode was unable to be produced; please see the Thrive Leads Section for further information.
- The CLOUDLINE T6 has perfected the art of customizing to a science.
- With variations in temperature within your grow tent, CLOUDLINE will automatically modify fan settings to adapt for the variations.
- As a result, you will never have to think about anything again.
- Making the decision to work with a system that does all of the heavy lifting allows you to keep a closer eye on your plants.
- In addition, the connection that connects the temperature controller to the fan sensor is eight feet in length.
- On top of that fantastic function, this fan is also pretty small in size.
The blower may actually be tucked between the floor joists to ensure that it remains stable.
While the first few settings are rather quiet, the volume increases exponentially as the speed of the machine increases.
This is a three-in-one solution that may be able to meet all of your grow room requirements.
It is important to remember that while you are using the dehumidifier, you must connect the unit to drain into a different container because the tray that is provided will not enough!
In a hot and humid atmosphere, there are three fan spans that are designed to break up stagnant air and circulate it.
You have the ability to program your remote control for up to 24 hours at a time.
When using the device, the LED screen is very simple to use and features clear text that can be seen from across the room.
Despite the fact that it is not as loud as the AC Infinity, it does not perform as well as the Casolly when it comes to noise canceling capabilities.
However, it is unlikely to be the most effective air conditioner for a grow tent.
It’s perfect for grow tents with fewer plants because it’s smaller.
The instructions will advise you to attach the vent hose to the section of the window panel that slides into it at the beginning of the process, but you should execute this step last.
If you’re looking for a loud song, this one takes the cake.
Despite the fact that it is meant for use in smaller spaces, this is a substantial piece of equipment for the tiny area it covers.
The fan continues to run without significantly lowering the temperature in the room.
This compact air conditioner is also ideal for use with a grow box.
The fact that this Black + Decker is both an air conditioner and a heater is what distinguishes it from the competition.
If you’re searching for a system that’s small and doesn’t take up much space, this little man packs a lot of power for his size.
In other words, if your plants are in desperate need of some cold, this will begin to work right away, saving your plants’ lives.
When components are connected to the hose, they have a tendency to flex and appear as if they would break if the pieces are handled incorrectly.
Expect to see these replaced at some time in the future.
So, while this may be the finest air conditioner for a grow tent, I wouldn’t want to use it in a room where I sleep when I’m not using it to grow marijuana.
In terms of eradicating mold, bacteria, and fungus in the air, the carbon filter is quite effective.
While the carbon filters are designed to survive for a lengthy period of time (up to a year and a half at the most), they must be cleaned periodically.
When compared to other other grow tent fans on the market, this Casolly is quite quiet.
The product is incredibly malleable, which makes it great for working around plants that are in the process of growing.
These are major problems when growing plants inside due to the fact that water vapors may cause significant damage to metals.
As far as the inline is concerned, it is not too hefty. You may lay it on the bars of the grow tent without having to worry about it falling to the ground.
Temperatures in Vegetative vs. Flowering State
When you are cultivating cannabis, there are two primary events that occur. For starters, cannabis is still in its vegetative condition. This is the stage at which the seeds germinate in the soil and begin to develop into buds. Finally, the blooming state, during which the plant blooms, is another state to consider. During these times, cannabis plants require a variety of various forms of attention, including temperature control. Temperatures between 70 and 85 degrees Fahrenheit are ideal for cannabis plants while they are still in the vegetative stage of development.
Other Temperature Tips to Keep in Mind
In order to replicate natural conditions, the temperature difference between night and day in your grow chamber should be 10 degrees Fahrenheit. The importance of this becomes much more apparent during the blossoming period. This temperature differential is critical in obtaining the highest possible yield.
Humidity in a Grow Tent
The presence of signs of dampness in your grow tent is a positive sign. That indicates that your plants are actively breathing and growing. Carbon dioxide is emitted by plants. The presence of carbon dioxide elevates the temperature of the atmosphere. The plants respond by releasing additional water vapor into the atmosphere as a result of this. More humidity is produced as a result of this. Increased humidity growth is also facilitated by higher temperatures. The reason for this is that heat causes water to travel through the air at a higher rate.
At the end of the day, you don’t want the humidity levels within your grow tent to exceed 70%.
Problems of Too Much Grow Tent Humidity
Despite the fact that humidity is beneficial, too much of a good thing may be detrimental. Increased moisture in the air may result in the growth of rot or mold. What makes the situation much worse is that you may not be aware of the problems until you begin harvesting your bud. It is possible that your greens are not getting enough water or nutrients because of white mold growing on their leaves. Instead, the white mold depletes all of the nutrients from the leaves, resulting in a reduced crop yield.
Problems of Too Little Humidity
However, you should make certain that the humidity level does not go below 40 percent at any point during the process. If this occurs, your plant’s growth will become static. When the humidity level falls below a certain threshold, the stomata, which are responsible for absorbing nutrients, will close. In addition, when there is insufficient water vapor in the air, the plant will retreat to its roots. As the roots of the cannabis plant get exhausted, the plant will lose all of its nourishment, rendering the yield utterly ineffective.
Hot Air Ducting for Grow Room
When cultivating cannabis indoors, lighting is really crucial. They do, however, create a great deal of heat. This can be quite harmful to your bud. Consequently, you must devise a method for directing the heat away from your grow tent. One method of accomplishing this is to run ducting from your light fixture to a window.
Make certain that the duct is running in a straight line to provide the greatest air circulation. A fan is attached to the ducting system. This fan will exhaust the hot air that is rising from the grow lights and away from the plants, and direct it to the outside air source.
Portable AC for Grow Tent
You may also purchase an air conditioner for your grow tent instead of a duct system if you choose not to use one. It is convenient to have a portable air conditioner since it can be moved about the room as needed. The use of an air conditioner is handy, but it has the potential to pollute the air with carbon dioxide. As a result, while selecting the finest air conditioner for grow tent, be sure to include carbon dioxide to provide your plants with additional nutrients. Visit thcoverdose.com/best-carbon-filter-for-grow-tent to learn more about the finest carbon filters available today.
Check to see that your air conditioner unit has an exhaust system before purchasing it.

Where to put my portable airconditioner?
What about a second tent for air conditioning? Yes, be certain that the air conditioning has’manual’ controls. Knobs and switches are as simple as they come. Furthermore, they are often less costly than versions that are operated digitally. I had one that I utilized at my last grow location, which was a room built inside another room in a basement that was unfinished at the time of the grow. We simply carved an outline of the A/C unit into our ‘wall,’ which was constructed of 1 x 1’s with panda filmcovered 4′ x 8′ insulation sheets, but I doubt that you would want to make a giant hole in your beautiful tent for the same reason.
- I’ve tried attic grows in the past and failed badly, but I have a friend who successfully grows in his attic, and he says the key to success is to use a second tent just for the A/C unit.
- When the air is forced through the cool tube, it remains cooler and less humid than the air in his attic.
- I believe that the same concept could be done for less money by building an A/C ‘chamber’ out of a 1″ PVC frame and covering it with Panda Film.
- It was so airtight that if I created another one, it would be much better.
- The walls would suck in when I turned on my lights and ran the Eclipse/Ostberg 630cfm fan, despite the fact that I had a decently big passive intake hole.
- For emptying the condensate, Little Giant manufactures an excellent pump with a float switch that works quite well for this purpose.
- Once the water level reaches a certain level, the unit will turn on and run its cute little pump for about 20 seconds, and then it will go off.
- It was even possible to have the hose going uphill in our basement garden, and the pump still had sufficient of power to handle the gradient.

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
The grow tent should always be equipped with at least one oscillating fan, regardless of whether or not you are ventilation your grow space. You’ll need many of them for large tents. You may find out which fans are the most effective for grow tents by visiting this website. They keep the air flowing over the plants at a consistent rate. Keeping things cold is important, but it also helps to prevent mold from growing. During the early phases of growth, when you want to increase the humidity levels in the grow tent, and during the latter stages, when huge buds and fan leaves obstruct air movement, this is very crucial.
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 Grow Tent
How To Keep A Grow Tent Cool Switch to LED grow lights to save money. Ballasts and drivers should be placed outside the grow tent.
Air should be circulated in and out of the tent. In the grow tent, keep an oscillating fan running. Incorporate a Swamp Cooler into your tent. Install a portable air conditioner in the tent. Turn on the lights at night. Relocate the grow to the basement or cellars.
How can I cool down my grow tent?
Air Conditioners for Grow Rooms and Tents If excessive temperatures are wreaking havoc on your indoor garden, there is no faster or more effective method to bring the temperature down than by using an air conditioner. You can simply install them either inside or outside the grow tent, and some versions even allow you to place them outside the tent while still allowing cold air to enter through a duct.
How do I keep my grow room cool in summer?
Maintaining a Cool Environment in Your Growroom Consider purchasing an air conditioner or a fan. Use a Swamp Cooler to keep things cool. Your Growroom Should Be Insulated or Relocated Humidity should be monitored and controlled. It’s time to rethink your lighting. Increase the brightness of the lights. Install a Light Mover in your home. Turn on the lights at night.
Should I run my carbon filter 24 7?
During veg stage, you should run the inline fan continuously, but if you want to extend the life of your carbon filter, you shouldn’t have it connected at all during flower stage. Only when the buds begin to give off their aroma should it be connected during flower stage if you need it to mask the smell. During the growing process, mine are unhooked until I need to filter the smell.
Is 32 degrees too hot for Grow Tent?
Moderator. Anything beyond 30 degrees Celsius/86 degrees Fahrenheit should be avoided at all costs. Because of the high temperatures, the plants become stretched and their buds become smaller and more airy. There are some strains that will fare better in hot temperatures than others.
Is 82 degrees too hot for Grow Tent?
Moderator. Avoid temperatures exceeding 30 degrees Celsius/86 degrees Fahrenheit. Stretchy plants with smaller and airier buds are a result of such high temperatures. It is true that certain strains are more tolerant of high temperatures than others.
Can you put a mini split in a tent?
You are capable of completing the task. I’ve completed the task. It is necessary to place a board on one side of the unit in order to really mount the indoor unit to it.
Can you leave grow tent open?
Yes, theoretically, you are allowed to keep it open. It is my goal to be able to control as many factors as possible, and growing under a tent allows me to do this. You’re exposing your plants to everyone and everything in the room as a result of this.
Should I leave my fan on when lights are off?
During daylight hours, both exhaust and oscillation fans should be functioning, as they should always be. If you have 2-3 oscillating fans, one intake fan, and one exhaust fan, you should leave the oscillating fans running throughout the whole dark time. In addition, switch off the other fans one hour after the light is turned off.
Do you need AC for Grow Tent?
If the temperature range in your grow room is consistently between 60 and 85 degrees Fahrenheit, you can get by with simply a dehumidifier and a fan to keep things running smoothly. If your grow room is enclosed, you’ll need to install an air conditioner.
How do you cool a sealed grow room?
To cool your space, you may use a variety of methods including venting, air-cooled hoods, water-chilled lights/fans, and water/air-cooled air conditioning. Venting to the outside is the most cost-effective method of removing heat from your space.
How do I increase the temperature of my Grow Tent?
Increasing the amount of light Addition of more light to your set-up is one of the most efficient methods of increasing the amount of heat produced in your growing environment.

What size air conditioner do I need for my grow room?
According to a common rule of thumb, for every 1 watt of high-pressure sodium light, the end user will require 3 BTUs of cooling power. Personally, I always add an additional 20% to this amount to allow for environmental fluxes and other factors. As a result, a grower using four 1000-watt high-pressure sodium lamps will require a minimum of 14,400 BTUs of cooling.
Why do you need fans in grow tent?
Effective grow tent ventilation is critical for healthy plant development, and effective filtration is equally important for cleaning the air and eliminating all aromas from the environment. Furthermore, it is critical to ensure that the air within your tent is circulated. This will help to keep temperatures and smells down, as well as strengthen plants, among other things.
How do you control temperature and humidity in a grow tent?
Methods for Lowering Temperatures Air exchange and overall airflow should be increased in your growth environment. A easy trick: turn the lights off during the day and turn them back on at night. When growing with High Pressure Sodium (HPS) lights, consider utilizing a cool tube to keep your plants cool. Install an air conditioning unit (air conditioners will also help to reduce humidity).
How do I keep my LED grow lights cool?
Make use of a dimmer ballast. While this may reduce the total quantity of light in the area, using a dimmable grow lamp allows you to adjust the amount of heat produced without entirely turning off the lights in the room. Cool the lights with circulating air. Using a separate ventilation system, you may directly cool your bulbs.
How hot is too hot for plants?
So, what temperature is considered “too hot” for plants? The overall answer is roughly 90 degrees Fahrenheit, with a few outliers to the generalization. This implies that when temperatures reach over 90 degrees Fahrenheit and remain there for an extended period of time, leaves wilt.
Can I put a portable AC in my Grow Tent?
It is possible to make it work, but you will need an air conditioner with two hoses that will vent outside of the area where the tent will be set up. This is due to the fact that if the AC and tent are in the same room that they exhaust into, you will have greater heat since it takes a significant quantity of vented heat to chill the interior of the tent.
Do you need AC with LED grow lights?
You should be aware, though, that indoor growth consumes a significant amount of energy, and it is probable that your power bill will increase.
The energy consumption of LED lights, on the other hand, is less than half that of HID (high-intensity discharge) lights. In addition, you’ll require air conditioning and a humidifier.
How do you cool a 3×3 grow tent?
All you need to know is how much energy indoor growing requires, and that your power bill will almost certainly increase as a result of your endeavors. While LED lights use less than half the energy of HID (high-intensity discharge) lights, HID lights consume more than twice as much energy. Air conditioning as well as a humidifier will be necessary.
Dealing with Heat in Your Grow Room Area
The temperature is the first and most crucial factor to consider in the summer, before all other considerations. For dealing with the out of control summer heat, I recommend that you invest in an air conditioner, add CO2, and seal your home or business. If you can manage the temperature in a growroom that has been enclosed and CO2 has been injected, you have created a “state-of-the-art” indoor growing environment. Then, when the summer heat has passed and the temperature has cooled, you may return to your “winter arrangement,” which includes exhaust fans controlled by a thermostat or other climate control system.
- These are available for purchase at most major hardware stores for between $400 and $600.
- In most cases, this form of air conditioner will not pull air from your room through its exhaust duct, which will aid in the reduction of CO2 emissions in your room.
- If you have to run exhaust for the entirety of the time that the lights are on in order to maintain a desired temperature, CO2 may have to be sacrificed in order to achieve that temperature.
- If you completely sealed off the space (except for the lights, which could be vented separately) and installed air conditioning so that you wouldn’t have to exhaust out of the area, you could run your CO2 in the area without wasting any energy.
- Even if you use air conditioning, if you are utilizing CO2, you can have temperatures in the low 90s without causing too much stress to the plants.
- Adding a silicate product to the mix can assist the plants cope with the heat if there is nothing else you can do and the temperature is expected to rise over 85 degrees without the CO2 supplemental.
- The Pro-TeKt from Dynagro When any of these silicates are included in your nutrition regimen, they will aid to alleviate heat stress whether or not CO2 is introduced into the room.
Cell walls in plant tissue are strengthened as a result of this treatment, which reduces transpiration while also making the plants more resistant to the heat.
How to Ventilate Your Grow Space
You must have adequate ventilation in order for your plants to flourish. By giving your plants with fresh air from outside your grow tent, you are supplying them with CO2, which is necessary for their photosynthesis. Meanwhile, removing the air inside will help to keep the temperature and moisture buildup under control, avoiding mold and mildew from growing on your plants’ leaves and so hindering their ability to thrive. The extra benefit of refreshing the air within is that it helps to eliminate unpleasant smells.
Essential Grow Tent Parts
When it comes to plant development, ventilation is essential. Supplying CO2 to your plants through the use of fresh air from the outside of your grow tent can help them to produce more food. Meanwhile, removing the air inside will help to keep the temperature and moisture buildup under control, avoiding mold and mildew from growing on your plants’ leaves and so hindering their ability to grow further. It has the added benefit of eliminating heavy scents from the air when you are refreshing the air inside.
Inline Duct Fan (Active Exhaust Fan)
An inline duct fan, also known as an extractor fan, is a device that is used to exhaust hot and humid air from within a growing chamber or tent. Even little variations in temperature and humidity may have a significant impact on your chances of generating a fruitful harvest. Furthermore, unregulated heat and humidity cause poor growth circumstances, resulting in your plants being unable to absorb water or simply failing to make it through the day. The use of an inline duct fan in your grow room is essential for controlling the climate in your growing environment.
Using an active exhaust fan to draw in cooler air can assist you in maintaining a comfortable inside temperature level.
In ventilation systems with passive intake, inline duct fans also serve as a vacuum, drawing in new CO2 from the outside air and bringing it into the system.
Extraction fans, also known as extractor fans, are used to exhaust hot and humid air from within a grow room or tent. They are also known as extraction fans. Slight variations in temperature and humidity can have a significant impact on your ability to produce a profitable harvest. Furthermore, unmanaged heat and humidity cause poor growth conditions, resulting in your plants being unable to absorb water or simply failing to make it through the season. The use of an inline duct fan in your grow room is essential for controlling the environment in your growing area.
You can manage the inside temperature more effectively by using an active exhaust fan to draw in colder air.
If your grow room is located in a cold climate, the amount of energy required to run your inline-duct fan will be influenced by how effectively your grow area is insulated. In passive intake ventilation systems, inline duct fans also function as a vacuum, drawing in new CO2 from the outside air.
A carbon filter will be required in order to prevent scents from traveling to your garage or closet. This device, which is also known as a carbon scrubber, removes the smell of plants from the air, capturing the odor and neutralizing it. Carbon filters are a must-have for growers that have to cope with very strong odors. They are also used to trap pollen and spores, which helps to keep the air clean for farmers who suffer from allergies or respiratory problems such as asthma.
Typical Grow Tent Setups
A charcoal filter will be required in order to keep scents from traveling to your garage or wardrobe. This device, also known as carbon scrubbers, removes the stench of plants from the air, capturing the odor and neutralizing it using a chemical reaction. The use of carbon filters is a necessary for farmers that deal with very strong odors. They are also used to collect pollen and spores, which helps to keep the air clean for farmers who suffer from allergies or respiratory problems such as asthma.
What Size Inline Fan do I Need?
There are many different sizes of grow areas, and each one requires a particular amount of airflow to be properly ventilated. It is critical for maximum plant growth that stale air within your grow room is exchanged with fresh air from the outside of your grow area. CFM (cubic feet per minute) is the unit of measurement for this number. To determine the quantity of airflow required for your grow room, first calculate the volume in cubic feet of the space. Most grow tent specifications are offered to you in inches; thus, you must convert the size of your space from inches to feet.
This will match the capacity of your grow room, and the needed airflow will be equal to this value in cubic feet per minute, or CFM, as well.
When the dimensions are added together, the result is 72 ft 3 in length.
Keep this amount handy since you’ll need to adjust it to account for the ducting, carbon filter, and any other accessories you decide to install.
Factoring in Accessories
In order to boost your base CFM, you must multiply it by the efficiency percentages of your accessories. Adding components to your grow room, including as ducting and carbon filters, may limit fan performance, which will have an impact on the fan size you require. When it comes to ducting, the quantity and sharpness of its bends play a role in determining the resistance to airflow. As a result, airflow decreases the longer it needs go, making a straighter ducting path more effective. The greater the sharpness of the curve, the greater the severity of the efficiency drop; a 30° bend reduces airflow by 20%, while a 90° bend reduces airflow by 60%!
- If you are utilizing LED grow lights, you must also take into consideration their heat production, which can raise your necessary CFM by as much as 50%.
- Because the efficiency of accessories on the market might vary substantially, you can utilize approximated efficiency percentages based on the type of component you are using.
- This amount is multiplied by the efficiency % of each component to arrive at the final result.
- Adding in the heat output of your grow lamp (about 50%) gives us a needed CFM of 249 cubic feet per minute.
- The following is a breakdown of this calculation: Multiplying your base CFM (72) by the percentages of ducting (20 percent), carbon filter (60 percent), silencer (20 percent), and grow light heat (50 percent) of your choice will yield approximately the 249 CFM you require.
- This will let the fan to operate at lower speeds while remaining quieter, as well as providing additional area for future expand space system growth.
Look for inline duct fans that are powered by direct current (DC) fan motors, which are the quietest as compared to alternating current (AC) fan motors. PWM-controlled EC motors are also acceptable in terms of acoustic performance.
How to Manage Grow Space Noise
There is no question that you will hear some noise when employing a high-powered fan to air your grow environment. You wouldn’t want to spend an extended period of time in an area with excessive noise pollution or catch the attention of your neighbors. Fortunately, you can plan your component selection with noise reduction in mind, and you can take further steps to make your grow area as as quiet as possible. Making the decision to choose a fan with speed controls and a CFM rating that is 25 percent more than your minimal need will allow you to run the fan at lower speeds without compromising performance.
If you want to further muffle the sound of your active exhaust fan, you may attach a silencer to it, which will lessen the sound of the intake fan.
