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’re still utilizing high-pressure sodium or high-pressure mercury vapor grow lights, it’s time to upgrade to LED lighting. In any case, visiting CMH is a good starting point. Do not even consider using HPS or MH if you are just getting started in the business of selling flowers. LED grow lights (and CMH grow lights, as well) are simply superior to older HPS or MH grow lights in every manner conceivable (except initial cost, though even that is fairly close these days). LED lights consume less energy to produce the same amount of light, and also generate less heat as a result of their design.
And there will be no need for bulb replacements after every two or three years.
You may save time by purchasing the HLG grow lights produced in the United States if you have the financial means to do so.
Consider one of the Chinese HLG clones if your budget is more restricted. Viparspectra Pro Series lights are unquestionably the finest, but if your budget is even more restricted, the Spider Farmer is a good option.
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
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 Down A Grow Tent Without AC
One of the most difficult tasks for marijuana farmers is keeping their growing environment cold enough to enhance growth and production. Of course, there are several things you may do, but they all require time, effort, and financial resources to be effective. It’s simply a matter of viewing it as a necessary component of indoor cultivation.
Be prepared to spend money on things like fans, ductwork, filters, and maybe air-conditioning systems as part of your renovation. You should also consider purchasing LED grow lights rather than obsolete HPS or MH lights (we still recommend CMH, though we prefer a quality LED).
- Using standard air fans
- Increasing ventilation
- Decreasing grow light intensity
- Utilizing intake and exhaust fans
- Using air or water cooled lights
- Improved insulation Running your business operations at night is a good idea.
Each of these topics is covered in great depth further down the page;
Best Ways Of Cooling Down A Grow Tent Without AC
Seven of the most effective ways to help cool down your grow tent without employing an air conditioning system will be discussed in this article. There are actually quite a few options, and the most of them are rather straightforward as well.
1. Use An Air Fan
A basic air fan is the first thing you can do to assist reduce the temperature in a grow room that does not have an air conditioning system in place. As a result, an air fan will assist in moving air about, and the simple movement of air should assist in cooling the air in and of itself. The flow of air does, in fact, result in cooling. No, an air fan will not solve the problem on its own, especially if the grow tent is really hot, but it is an excellent starting point. In this case, it is critical that you get a fan that is both energy efficient and cool to the touch.
This post is a review of our favorite clip from the fandom.
2. Create More Ventilation
It is also important to note that increasing ventilation, even in the absence of an air conditioner, will surely assist to cool down a grow tent or grow room. It is no longer necessary to use powered ventilation, such as ducts and an intake and exhaust system, to accomplish this. You may just leave the door to the grow tent open a little bit, cut a hole someplace, or simply leave the vent holes uncovered rather than covering them if you like. Remember that heat rises, therefore the ideal areas to leave open are those near the top of the grow tent, where the air can circulate.
In addition to allowing heat to depart the grow tent, it will also enable new and cooler air to enter, which will aid in the regulation of humidity while also providing your plants with extra oxygen.
3. Reduce Grow Light Strength – LED Lights
Grow lights are one of the most significant sources of heat generation in a grow tent. If you have a large tent with a lot of lights, especially bright lights, they will very certainly operate to significantly heat your tent, maybe to the point where it is no longer optimal. What you need to know is that certain grow lights run really hot and generate a tremendous amount of heat, whilst others produce little or no heat at all, which is important to understand. To summarize, using LED lights to maintain an optimal temperature for marijuana development may be a good option in this situation.
LED lights have the advantage of running substantially cooler than all other types of lights, which can help to reduce the temperature of the grow room by a few degrees. If you have huge HPS, Halide, or other types of grow lights, this is most likely the reason why your grow tent is so hot.
4. IntakeOuttake Fans
The grow lights in your grow tent are one of the most significant sources of heat generation. The use of bright lighting in a large tent will almost certainly result in a significant increase in the temperature of the tent, maybe much above what is considered optimal. In this case, it’s important to understand that certain grow lights run extremely hot and generate a great deal of heat, whilst others create little or no heat at all. To summarize, using LED lights to maintain an appropriate temperature for marijuana development may be a good option in this situation.
You may be experiencing excessive heat in your grow tent if you have huge HPS, Halide, or other types of grow lights.
5. Air Or Water Cooled Lighting
The use of lights that are either air or water cooled is the next method of keeping things cool in the grow room. This is what you must do if you want better illumination than the ones provided by standard LED lights. LED lights are good, because they keep the plant’s temperature down, but they don’t produce the finest-quality buds or the largest yields. There are various types of grow lights available that produce far larger and greater harvests, but they generate a lot of heat. Here, the solution is to invest in high-quality grow lights that are equipped with an integrated air-conditioning system.
Water-cooled systems, on the other hand, often perform better in terms of cooling and temperature control, but they are far more expensive and require significantly more maintenance.
6. Better Insulation
Just be aware that this insulating point can work both ways, as previously stated. More insulation in your grow tent will actually make it seem warmer if you live in a cold environment; but, insulating your grow tent to keep heat out will undoubtedly make a significant impact if you live in a hot area and need to cool things down.
7. Run Your Operation At Night
The third approach to keep your grow tent cold, and to assist in cooling things down without the need of air conditioning, is to leave the grow lights on throughout the nighttime hours. Of course, nighttime is far colder than daylight, so if you run your grow lights at night, the heat generated by the lights will not mix with midday heat, resulting in temperatures that are not as high as they would be otherwise. To be sure, when growing vegetables in your pots, you can leave your lights on all day and night.
The reality of the issue is that, without a question, an air conditioner is the most effective method of cooling a grow room. However, they take up a lot of room, consume a lot of energy, are noisy, and you might not want one for a variety of other reasons.
Nonetheless, as you can see, there are multiple effective methods of keeping a grow tent cool without the need of an air conditioner. In order to achieve the greatest outcomes, if you absolutely need to, combine all of the approaches we’ve outlined here for the best possible outcome.
How to Cool A Grow Tent? – 10 Actionable Ways to Take
What do you think the months of June through August are like for you? We’d say it’s scorching. And when given the opportunity, we run under the air conditioners or at the very least beneath the fans to cool ourselves off. If that’s the case with ourselves, why shouldn’t it be the same with the plants? We’re talking about an agrow tent in particular, to whom you’re pretended to be ‘Mother Nature’ from every angle possible. Consequently, if you’re concerned about how to cool a grow tent that’s becoming excessively hot, it’s quite OK to choose that route.
Listed below are five strategies for keeping the temperature of a grow tent under control.
Let’s get this party started-
What Turns a Grow Tent Hot?
Before we can learn how to cool down a grow room, we must first understand what is causing the abrupt increase in temperature in the space. Throughout this section, we’ll refer to each of the probable explanations by their proper names. Let’s have a look-
- It is necessary to understand the causes of abrupt heat rise in a grow room before we can learn how to cool it down effectively. Throughout this section, we’ll refer to each of the various explanations by their formal names. See what we can find out.
Have you acknowledged each and every one of them? Let’s have a look at some of the various solutions for getting them sorted out for a good purpose.
Ways to Cool A Grow Tent- Without Products
During this first section of the solutions, we’ll speak about several improvised methods of cooling down a grow tent. These will not be associated with the purchase of any items or the incurring of any costs in any way. All of the action will be focused on improvisation, optimization, and correction. Let’s have a look at it-
Way 1: Get the Best Out of the Ventilation Scopes
Grow tent kits available on the market are equipped with vent holes through which you may insert carbon filters, ducting into and out of the tent, and anything else that may be necessary. On that note, you must make certain that these venting chances are utilized to their full potential. And this will eventually result in a reduction in heat accumulation and a decrease in temperature. Another challenge that may be addressed from this position is the maintenance of appropriate airflow. You may increase ventilation by following a few simple guidelines that can be implemented with any available resources you may have at your disposal.
- Reposition the clip-on or stand fans throughout the grow space to better suit their needs. Additionally, if they offer to modify the speeds, you can do so. Relocate the location of the input duct opening to the coolest suitable location in the immediate vicinity. When this is done, cold air will be drawn into the tent, resulting in a dramatic reduction in the temperature within. If they have not previously done so, they should consider adequately closing the vent openings.
Way 2: Diminish the Heat Sources as much as Possible
The most basic approach to cooling down a grow tent is to utilize goods that chill the air. However, if we believe contrary, we may achieve the same result by reducing the amount of heat that is produced within a tolerable range. And it works just as well as the first method. When it comes to naming heat sources in a grow system, there are just a handful that come to mind. Let’s have a look at the list:
- The lights (1 source of heat)
- Space heaters
- Motor-driven devices
- Soil that carries heat inside it
- And other sources of heat
Now, let’s speak about the grow lights first, because they are the primary contributors of pollution in this environment. In the first place, lights must be kept at a safe distance from the plants’ roots. After that, you can switch to using air-cooled light hoods instead of ordinary light hoods. Because these hoods take care of the hot air that is generated by the lights and prevent it from entering the grow area. Aside from these two points, there are a couple of small details that you should be aware of.
Additionally, you must employ automatic controllers to turn off the lights when they are not required.
When it comes to other sources of heat, you may use the same tactics that we recommended for lighting. As you are well aware, it is essential to restrict the amount of heat produced to a comfortable level.
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.
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’s critical to consider where the grow tent will be positioned in your home, as long as the heat difficulties are taken into account. In most cases, growers choose to maintain their plants in secluded locations such as the garage or cupboards. For those who aren’t among them, though, here are some pointers. Place the grow tent away from the south-facing wall of your home. This will help to keep the heat out. This is likely to prompt thoughts about how to construct a perimeter around the grow tent, among other things.
The heat of the sun is transferred to the tent through the neighboring air, causing the tent to inhale hot air as a result of this.
It is preferable to keep them deep within your home or garage, where they will not be exposed to the sun by any of the roofs or walls of the structure. Do not be concerned about ventilation; you will be able to handle it yourself.
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. They typically produce a respectable BTU output and are easily transportable. As a result, while it cannot be used in the tent, it may be utilized in other situations. Mini Air Conditioning Units that We Recommend However, if the grow room is really huge, we offer split air conditioners that perform well. 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.
- 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.
Furthermore, with a water-based chiller, this possibility is well within the acceptable range. However, in the best-case situation, we recommend that you use a decent humidifier to deal with any humidity issues you may be experiencing. Water Base Chillers We Recommend are shown below.
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.
Hey, we’ve reached the end of the road. Pat yourself on the back because you’ve just finished writing a 2000+ word post about how to cool a grow tent using a variety of methods. As a last recommendation, consider the location of your grow tent and the solutions on the list to see which one is the most appropriate. If it is necessary to make a financial investment, do not be afraid to do so. Because, in the end, it will reward you with a handful of robust, quantitative crops, which will be well worth your time.
Best of luck with your growth!
How To Cool Your Grow Tent Without An Air Conditioner
In the grow tent, use an oscillating fan to circulate the air. These fans keep the air flowing over the plants at a constant rate. Not only does this assist in keeping things cold, but it also helps to prevent the growth of mold.
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.
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.
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.
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.
How do I keep my grow room cool in summer?
However, if you choose to save money on the initial investment, there are a few additional options available to you. At night, turn on your lights. Because everything is colder at night, it is much easier to maintain cool temperatures throughout the day. Fan and temperature controls should be used. Make use of a dimmer ballast. Cool the lights with circulating air.
Is 30 Degrees to hot for grow room?
Other options are available to you if you like to save money on the first investment. At night, make use of your overhead lights to illuminate your surroundings. It’s considerably simpler to maintain cold temps at night since everything is much cooler. Control the flow of air and the temperature with fans and thermostats Use a dimming ballast to get the desired lighting effect. Cool the bulbs using circulating air (if possible).
What happens if grow room is too hot?
A poorly ventilated grow room can cause a variety of other issues with your plants in addition to overheating. In the first place, increased water transpiration at high temperatures can lead to nutritional decomposition. Terpenes can also be lost from your plants if they are overheated, resulting in the loss of the distinctive flavors and fragrances from your strains.
Will a dehumidifier cool a room?
Because they significantly reduce humidity, dehumidifiers are effective at cooling a space. Humidity is the primary source of discomfort in a room. Humidity is defined as the heavy humid sensation you get when there is an excessive amount of water vapor in the air. As a result, dehumidifiers may also function as air conditioners, because all of the air that is left is dry and ready to chill.
Can you leave your 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.
Is 82 degrees too hot for Grow Tent?
Temperature for Seedlings is important. The majority of grow tent plants require a temperature range of 72 degrees to 82 degrees Fahrenheit to be maintained. Make certain that the temperature does not surpass 82 degrees Fahrenheit.
Why is my grow tent so hot?
Heat rises to the top of your grow tent/area, therefore make sure your exhaust fan is situated at the top of the tent with the blades directed away from the grow area.
Because a small intake hole puts strain on your fan, the exhaust will not be able to expel as much hot air as it should, and the walls of your tent will begin to sag.
Is it OK to sleep in a room with a dehumidifier?
In fact, sleeping next to a dehumidifier is absolutely safe in most cases. If you are specifically interested in a dehumidifier for the bedroom, the noise level will be of special importance to you while making your decision.
How can I keep my room cool without AC?
How to keep cool when there is no air conditioning Take a shower or a bath in cold water. Apply cool washrags to the back of your neck and wrists. Make use of box fans. Close the drapes or blinds in your room. Sleep on sheets that are both breathable and comfortable. Sleeping in the basement is a good idea. Blankets and garments should not be refrigerated or frozen. Close the doors to any rooms that aren’t in use.
Is it cheaper to run AC or dehumidifier?
In most cases, running a dehumidifier is less expensive than running an air conditioner if both units have average capacities and run for the same amount of time. This does not imply that you should abandon your air conditioner in favor of a dehumidifier, since each device serves a distinct purpose.
Is 90 to hot for Grow Tent?
For example, if you’re increasing the amount of CO2 you’re feeding to your plants, the temperature in your cannabis grow room should be elevated to 86-90 degrees to ensure optimal absorption. Temperatures during the “nighttime” period should be somewhat lower, about 71 degrees, to minimize stretching while still allowing your plants to “sleep” and recover.
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.
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.
How do you cool a 4×4 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 hot is too hot for a grow tent?
It’s important to remember that the maximum temperature for successful marijuana grow tent operation is 85°F if you’re growing marijuana in a grow room. Temperatures that are greater than this will cause the plant to die.

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.
It’s fine if you haven’t finished constructing your grow room. However, if you already have one, you may be experiencing severe discomfort as a result of the increased warmth. To begin, consider the most likely causes of the problem-
Too Many Heat Producers
The most significant source of heat in a grow room is the lighting. However, there are some objects that produce heat that circulates throughout the area. Examples include light ballasts, large pumps, and other such items.
Not-so-Insulated Location of the Grow Tent
For the past two years, I’ve worked as a grower. And, right from the start, I started growing plants in my basement. Growing in such a well-insulated space allowed me to get temperatures that were at least 5°F lower than those obtained with the same arrangement planted anyplace else in the home. And when the plants become overheated as a result of one or more of these factors, they begin to exhibit symptoms of stress. As a result, the amount of bloom or fruit produced is minimal. Please read the next sections of the post if you want to learn about some practical strategies to keep your grow room cool in real time.
7 Grow Room Cooling Solutions That Actually Work
When it comes to chilling a restricted place like as your grow room, nothing compares to the effectiveness of an air conditioner. It not only cools the surrounding environment, but it also removes the heat created by equipment such as blowers, generators, pumps, ballasts, and other similar devices. ACs of varying sizes are likely to be utilized by growers. These are sometimes labeled in terms of BTU (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU, 36,000 BTU, 48,000 BTU), and sometimes in terms of weight (8,000 BTU, 10,000 BTU, 12,000 BTU, 24,000 BTU, 36,000 BTU, 48,000 BTU) (1 Ton, 2 Ton, 3 Ton, 4 Ton).
Take notice that, while many growers employ portable air conditioning units, window air conditioning units, and other similar devices, a ductless mini split system is the most efficient.
As a result, you can’t always rely on your air conditioner to do all of the cooling duties.
Take Care of The Ventilation
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. After that, spend some money on an automatic controller that adjusts the fan speeds in response to changes in temperature, such as a thermostat.
Structurize The Grow Room
A tent that is overcrowded is never a good thing. Every tent has a limit to the number of plants that may be accommodated within it. The presence of an excessive number of plants can result in a variety of problems, one of which is high temperatures.
Using Smart Pots
The use of smart pots to house plants in order to assist them cope with heat stress is an excellent solution. These can assist in surge evaporation, which reduces the likelihood of overheating, as well as maintaining the health of the plants by delivering oxygen from the sides. The use of Coco air is another clever pot hack that aids with the cooling of the growing tent. Your plants will be more resistant to the heat as a result of it. There are a number of additional substances that can aid in the battle against heat stress.
Optimize The Lights
Lights are the primary source of the potentially hazardous heat surges. There are a few instances in which lights can behave more like heat sources than they do as lighting sources. The methods are as follows:
- When the plants reach maturity, the lights should be dimmed. Extreme heat generation as a result of low-quality lighting
- There is insufficient airflow between the lights and the plant canopy. Leaving the light on when it isn’t essential (during the day)
Several things may be done to optimize the lights in order to reduce their heat-generating effects, including:
Raise The Lights
Raising the light by 8-10′′ might be used as a temporary remedy to minimize direct heat impacts from lights on your plants.
Install A Light Mover
Some hot spots and uneven lighting across the area might be caused by light sources that are fixed in one location. Consider taking up residence in a motorized mover. Using a curved track, they may convey the lights back and forth or around a corner. As a result, the light dispersion across a large region becomes more uniform, which is advantageous. Additionally, it minimizes the amount of hotspots and the problems associated with canopy overgrowth. First and foremost, it contributes to lessening plant damage caused by excessive heat exposure.
Run Lights At Night
When compared to the daytime, the nighttime temperature is a few degrees colder than the midday temperature. Growers, particularly those who live in hot climates, should avoid making the mistake of turning on lights during the daily hours. Because the temperature has already risen by a few degrees at that point. Rather, turn on the lights at night. It will help to keep the temperature under control. And it’s possible that it will prevent the power bill from skyrocketing. In a manner, you’re saving both energy and money at the same time.
Use Air Cooled Lights
Using air-cooled lights is an excellent technique to keep lights from creating heat and causing problems. In order to exhaust the hot air from the bulbs, they might be linked to the ducting system. The process will be accelerated even further if the insulation is properly installed. If you want to take it a step further, you may go for lights that are water cooled.
They are equipped with a water reservoir and a water pump in order to preserve water. It is possible that a water-cooled light can discern the essence of an air conditioning unit in a grow tent that has been properly sealed.
Ensure Proper Ducting and Insulation
Lighting that is equipped with an air cooling system is a fantastic way of keeping your home cool. In order to remove the hot air from the bulbs, they might be linked to the ducting systems. It will be much faster if you use good insulation throughout the building. A step further might be taken by investing in water-cooled lighting fixtures. To conserve water, they are equipped with a reservoir and a water pump. The core of an air conditioning unit may be deduced from a water-cooled bulb in a fully sealed grow tent.
- 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
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.
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|
Generally speaking, there are three types of air conditioning systems: portable, split and window. While these three types differ in terms of size, use, features, and, of course, price, they are all similar in terms of their basic functionality. Utilizing a portable air conditioner that is within your budget will suffice if you’re using a 2X4 or 5X5 grow tent. Split air conditioners, on the other hand, are the greatest choice if you’re growing in a bigger space, such as grow rooms. We also believe that a window air conditioner would not be an economical choice for a developing room in the third instance.
While we wait for the perfect air conditioning equipment for your growing room or tent, here are our top picks:
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
In a growing environment, chillers are responsible for absorbing any excess heat that accumulates. Water-cooled chillers as well as air-cooled chillers are also available options. Despite the fact that they cost more, most growers choose water chillers. The water in the reservoir and the fertilizer solution are the heart of a hydroponics water chiller system, which is used to grow plants. The combination of water and nutrient actively contributes to the cooling of the water. Water chillers, once again, are exclusively suitable for indoor hydroponics.
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. Here’s a quick rundown of the options:
- The ability to dim the light
- Reflector hood lights
- Plant fertilizers and vitamins
- And smart pots are all included.
It should be noted that using all of these things to manage the temperature in virtually any grow environment is effective. However, the trouble arises when you are unsure of ‘How Big’ or ‘What Kind’ of merchandise you should purchase once you have decided on your budget. This is because, depending on the size of your grow tent, the kind of power provided by each of these devices varies significantly. You should be certain of this if you choose a remedy to deal with the heat problem.
Check If You’re Making These 4 Mistakes Or Not-
- It Should Be Mentioned: Using all of these tools to manage the temperature in virtually every grow room is a successful strategy. It becomes an issue, though, when you are unsure of ‘How Big’ or ‘What Kind’ of merchandise you should purchase with your money. Because the kind and strength of each of these things will vary greatly depending on the size of your grow tent. You should be certain of this before purchasing a device to deal with the heat issue.

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

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

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

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

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