Marijuana Grow Room Setup: Optimal Humidity and Temperature
Despite the fact that it is exhilarating to see the benefits of your effort when you begin harvesting, the task is far from finished. Preventing the possibility of your crop getting destroyed or rendered unusable for smoking by properly processing it is important. Proper drying and curing are critical in reducing the possibility of mold infection while also significantly improving the taste of the product when it is smoked.
Beyond the requirement for precise temperature and humidity management during the growth phase, it is also crucial to note that the humidity level maintained during the drying process is critical to the quality of finished product. If you have too much humidity in your drying environment, you may end up with perfectly cultivated cannabis that is moldy. That is something that neither the individual user nor the dispensary purchaser desires. Having moldy cannabis on your hands is one of the most effective ways to tarnish your reputation as a dependable grower of high-quality buds.
Wet Trimming versus Dry Trimming
A less bitter flavor is produced as a consequence of the curing process, which breaks down any residual chlorophyll in the plant. Keep in mind that harsh buds are not high-quality buds. These techniques can extend the shelf-life of a crop, which is particularly significant for a product like cannabis, which does not have the option of adding preservatives to prolong its shelf life.
When chlorophyll is broken down in the plant, the flavor becomes less bitter as a result of the curing process. It’s important to remember that harsh buds are not high-grade buds. A crop’s shelf life may be extended by the use of these processes, which is particularly significant for a product like cannabis, which cannot be preserved through the use of preservatives.
When chlorophyll is broken down in the plant, the flavor becomes less bitter. It’s important to remember that harsh buds are not high-quality buds. These processes can extend the shelf life of a crop, which is particularly significant for a product like cannabis, which does not have the luxury of adding preservatives.
Drying Room Conditions
Whatever method you use to trim your product, it is critical that the drying chamber be set up in the proper circumstances. You’ll need a cold, dark atmosphere with temperatures ranging from 59 to 71 degrees Fahrenheit and humidity levels at or around 50 percent. Yes, even after the growth process has been done, you must continue to be careful with temperature and humidity conditions.
The Drying Process
If you want to utilize the wet trimming approach, you will need to spread them out across a big surface area in order to get the desired results. Because aeration is critical, you should avoid placing the flowers on a flat surface such as cardboard or newspaper, as the buds may dry unevenly on these surfaces. The use of wire mesh or netted drying racks is more advantageous. This allows circulation to reach all corners of the room and reduces the likelihood of wet air pockets forming. Make sure to give yourself enough space to spread your crop out evenly, with a tiny bit of space between buds, in order to get the best possible outcomes.
Excessive hurrying through the process and exposing your crop to high temperatures will almost surely result in worse quality, poorer flavor, and even the possibility of a “bad and unpleasant high.” Good luck explaining it to your investors or to a discerning dispensary that has a slew of producers fighting for shelf space in their establishment.
Here is the item that you may utilize to assist you in reaching these levels once more:
- Temperature and humidity levels are measured with a thermo hygrometer. Air conditioner
- Portable heater
- Thermo hygrometer
Ensure that you inspect your crop on a regular basis, generally every three to seven days. With each inspection, they will get considerably drier and more comfortable. It will be clear that your buds have been adequately cured when they break easily in your hands and show no symptoms of stringiness or wilting. If you see any bendiness when you twist gently, this indicates that there is still water present and that they are not yet ready to be transferred to jars.
Temperature & Humidity 101
Growth and self-maintenance of plants are strongly reliant on their environment, which includes taking in sunlight for photosynthesis and utilising the air to keep cool and serve as a source of carbon dioxide. Because various plants require varied environmental conditions, it is critical that the temperature and humidity in their environment be precisely perfect. However, because these two elements fluctuate so dramatically with seasonal transitions, the plant’s development might be severely restricted.
- They will be able to take advantage of their optimal weather conditions on a consistent basis, which will help them develop faster and produce more yield.
- This also helps to prevent hot or humid areas by matching the conditions within the grow tent with the environment outside.
- Whether you are starting out with a grow tent or operating a modest business with a grow room, an inline duct fan is the most important tool you can have for ventilating your grow area and managing the temperature and humidity levels in your growing environment.
- So, in this section, we’ll look at how each aspect affects your grow’s performance and how to control them to your advantage.
What is Temperature?
In order to maximize yields, you as a farmer will need to monitor and modify the temperature, which is one of the four key environmental control parameters you will need to monitor and manage. Humidity, illumination, and ventilation are the other considerations. In order to achieve perfection, temperature must be controlled precisely since it influences how effectively seeds germinate and how efficiently plants can photosynthesize, bloom, and produce fruit. However, most plants survive at room temperature, which varies depending on what you want to produce in your growing environment.
- Their yields may be less, of inferior quality, or they may not be able to live if they don’t do so.
- Heat sources, like as your grow light and the exterior climate, can raise the temperature of your grow room, depending on your location and circumstances.
- If the temperature within the grow tent is too high, your plants’ stomata, which are responsible for transpiring water vapor, may close.
- Furthermore, the sugar energy that your plants worked so hard to produce blooms and fruit would be diverted to the organism’s own needs for survival.
Coldness, in addition to usually slowing down and reducing development, can cause your plants’ cells to freeze and, if temperatures are extremely low, induce tissue death in some cases.
What is Relative Humidity?
The quantity of water vapor in the air at a certain temperature, which is invisible to the naked eye because it is in a gaseous condition, is referred to as relative humidity. In the atmosphere, water vapor is produced by a variety of sources, including animal respiration, evaporation from snow and bodies of water, and plant transpiration, among others. After a while, the water vapor condenses and becomes visible in the form of clouds and fog. The amount of water that your plants transport through their stems and leaves is regulated by relative humidity, which impacts how fast they develop and how well they thrive.
- Plants transpire in a similar way to how we people sweat, which contributes to the increase in relative humidity.
- Photosynthetic activity is halted when the stomata are closed entirely.
- Only around 5 percent of the water that plants take in is retained, with the other 95 percent being released back into the environment.
- This will help your plants to breathe more freely, allowing them to stay cool and absorb nutrients from their surrounding environment.
- This exposes them to scorching and drying out, while at the same time preventing them from absorbing further water and nutrients.
- In contrast, if the humidity in your grow room is too low, your plants will dry up since they will attempt to transpire in order to compensate.
Thermometers and Hygrometers for Grow Tents
The quantity of water vapor present in the air at a certain temperature, which is invisible to the naked eye because it is in a gaseous condition, is referred to as relative humidity. In the atmosphere, water vapor is produced by a variety of sources, including animal respiration, evaporation from snow and lakes, and plant transpiration. At some point, the water vapor condenses and becomes visible in the form of clouds and fog. The amount of water that your plants transfer through their stems and leaves is affected by relative humidity, which impacts how fast they develop.
- Opening their stomata, which is the sole way for plants to photosynthesize, allows them to do this.
- Make certain that your space is well sealed and insulated in order to reduce the impact of outside influences on the ventilation of your grow tents.
- Because of the large amount of water that is returning to the atmosphere, it is critical to maintain the relative humidity inside your grow tent at a constant and appropriate level.
- If the humidity in your grow room is too high, your plants will be unable to transpire and will instead retain the water that they have collected through transpiration.
- Humidity can also cause bud rot and the growth of mold and mildew on the leaves.
However, if the humidity in your grow room is too low, your plants may dry out as they attempt to adjust for the low humidity level by transpiring. In order to keep themselves from drying out more, your plants’ stomata will close and photosynthesis will be suspended.
How to Adjust TemperatureHumidity
When the weather becomes excessively hot or humid, the approaches and scenarios listed in the graphic below can be used to combat the situation. Prior to employing any of these technologies, you may reduce the impact of the exterior temperature on your grow area and eliminate fluctuations and light leaks by properly sealing and insulating your grow room with appropriate materials. Maintain proper plant spacing as well, because overpopulation will result in higher humidity levels. Using the following and other tools to assist you stabilize your growing environment if you find that you need to make modifications to meet your requirements:

Applying adequate sealing and insulation in your grow room prior to using any of these techniques will help to mitigate the effects of the outer climate as well as eliminate fluctuations and light leaks. Maintain proper plant spacing as well, because overcrowding will result in higher humidity levels. Using the following and other tools to assist you stabilize your growing environment if you need to make modifications to meet your needs:
How To Lower Humidity In A Grow Tent
Extreme amounts of humidity are detrimental to plants, just as they are to practically everything else. Certain occurrences, both within and outside of grow tents, are responsible for the variability in relative humidity levels. It is necessary to adjust humidity levels at different seasons of the year for different types of plants, such as seedlings or flowering plants, and therefore it will be necessary to raise or decrease humidity levels at various times. A few suggestions for controlling humidity in a grow tent are included in the section below.
1. Do not flood your plants
You may find yourself overwatering your plants from time to time, most likely because you believe the plants aren’t getting enough water. Over-watering your plants, on the other hand, will impair their ability to transpire effectively depending on the temperature within the tent. When the atmosphere is saturated with water vapor, the rate of transpiration slows to an amount that may be detrimental to the health of the plants.
2. You could try defoliation
This is little more than the removal of leaves. Larger leaves naturally leak more moisture than smaller ones, so if you find yourself with an excess of huge leaves in your grow tent, you might want to consider clipping a few of them off to see if you can lower the quantity of moisture the leaves release by a tiny amount.
Allowing fresh air to enter your grow tent. High humidity can be reduced by allowing a small amount of air to blow away the moisture in the environment. It also improves the capacity of your plants to release moisture. It is possible that you will puncture your tent. Holes that are large enough to allow air to flow through them. Don’t forget not to overdo it, since excessive aeration would result in extremely low humidity, which would encourage the plants to draw water from the soil.
Take aware of the fact that opening and closing your grow tent on a regular basis might allow scents to escape into the room. Furthermore, if you keep your grow tent in a storeroom, it may expose the plants to rodent assaults, which might be harmful to them.
4. Make use of a dehumidifier
A dehumidifier does exactly what it says on the tin by removing humidity from grow tents. Grow tents are equipped with dehumidifiers that are specifically developed for them. This is one method of reducing humidity without having to perform a great deal of physical work or effort. Everything is handled by the machine. The only thing you’d have to do is empty it when the water tank is refilled. These are just a few methods for lowering the humidity levels in your tent. There are many more. Not every one of the suggestions listed above should be implemented since doing so would be very cumbersome and would result in dangerously low levels of humidity.
There will very certainly be situations in which higher humidity levels are required.
Here’s how to control temperature and humidity in grow tent.
A hose connects a bucket of water to the humidifier, which then circulates the water. When the water is finished, it is pumped into the humidifier, which fills the space with moisture and increases the humidity in the air. Some humidifiers have controls that allow the user to modify the humidity. This alone may be sufficient to boost the humidity level, but what happens if you are unable to buy one at the present time?
2. Reduce the dehumidifier’s settings
If you have a fan that extracts moisture, you might set it such that the rate at which it removes moisture is reduced. As a result, more moisture is left in the environment of your grow room, providing your plants with additional moisture for development.
3. Bring in larger plants
When compared to plants with small leaves, big leaves transfer moisture more efficiently. The stress placed on them by the dry conditions is less than the stress placed on smaller plants, which would alleviate the stress placed on smaller leaves. You might just add a few plants with greater leaf sizes to your garden. Even better, you can put plants together in a cluster to save space. Due of this, the plants are able to transpire together and as a result, they end up generating their own little humidifier.
4. Reduce grow lamps
Reduce the amount of grow lamps in your tent if it becomes required. These lights create heat, and heat dries out the air and reduces the humidity levels in the environment. The greater the number of them, the greater the quantity of heat produced, and vice versa.
5. Control Airflow Into Your Tent
Reduce the amount of grow lamps in your tent if it is absolutely required to. They create heat, which dries out the air by lowering humidity levels and dries out the environment. The greater the number of them, the greater the quantity of heat generated, and vice versa. Some of the links on this page may result in commissions for us.

What Happens If the Air in the Grow Room Becomes Too Dry?
When your plants breathe dry air, they lose more water than they would if they breathed moist air. This has the effect of decreasing the total moisture content of your cannabis. If the environment becomes too dry (low humidity), your plants will lose more moisture than they will be able to replenish through their roots. If this occurs, your plants will seal the pores in their leaves in order to reduce water loss. – It is a successful strategy, but it implies that they will get less CO2 from the environment as a result.
- When the weather is dry, it is easy to believe that you can just water your plants more frequently.
- Your plants will suffocate and become more susceptible to root rot as a result of this.
- The reason for this is because it permits moisture to accumulate in the plant’s dense leaves, which is beneficial.
- They open their pores, breathe CO2, and develop at a rapid pace.
Naturally, the duration of the marijuana plant’s life cycle is a determining factor in its yield. These data serve as an excellent starting point. However, depending on the strain, you may choose to adjust the humidity just a smidgeon higher or lower:
- Clones require 60-80 percent relative humidity
- The vegetative stage requires 50-60 percent relative humidity
- The early flowering stage requires 40-55 percent relative humidity
- And the late flowering stage requires 40-50 percent relative humidity (although it can be as low as 30-35 percent depending on the strain).
60-80 percent relative humidity (RH); 50-60 percent relative humidity (RH); 40-55 percent relative humidity (RH); 40-50 percent relative humidity (RH can be as low as 30-35 percent depending on the strain); 60-80 percent relative humidity (RH).
1 – Seal and Insulate Your Room
One of the most important principles of effective indoor marijuana cultivation is to make certain that your grow room is properly sealed and insulated. Commercial construction companies employ foam insulation and other materials to form a barrier between the grow room and the surrounding environment outside the building. Those who live in humid climates may believe that this recommendation does not apply to them. However, this is not the case. It is, however, still necessary, regardless of whether you live in Colorado or New Mexico.
Together with a few other elements, these three have a considerable influence on the temperature of the environment.
If you correctly insulate your grow room, you won’t have to be concerned about outside elements affecting your harvest.
2 – Control Grow Room Temperature
When you cultivate marijuana outside in a proper environment, you don’t have to be concerned about the weather as much as you would otherwise. The weather, on the other hand, can still have an influence on your crop, particularly if there is an unseasonably warm run of weather. Lighting is critical for indoor gardeners since it allows them to see their plants. While it may be tempting to utilize bright lights, too much illumination may cause the temperature in your grow area to rise dramatically.
As a result, temperature variations are frequent and have a negative impact.
The deadband is a temperature range of 3-5 degrees Fahrenheit around the setting that you have set the thermostat in the room at.
This assists in maintaining the proper temperature in the grow chamber.
The Importance of Using a Suitably-Sized AC Unit
It is not need to be concerned about the weather when growing marijuana outdoors in a suitable environment. In any case, weather can still have an influence on your crop, especially if there is an unseasonably warm run of weather. Lighting is extremely vital for indoor growers. When growing plants, it is tempting to use bright lights, but too much lighting causes the temperature in your grow room to rise dramatically. An air conditioning system that is either either too huge or far too tiny for the grow room is a typical blunder.
Among the most important considerations in air conditioning and temperature change are brief cycling and deadband.
When the temperature rises to the higher end of the deadband, your air conditioning equipment will kick in to keep you cool.
Keeping the grow chamber at the appropriate temperature is made easier as a result of this. In order to prevent the room from becoming excessively chilly, the air conditioning turns off when the temperature hits the lower end.
3 – The Importance of Air Movement
When you cultivate marijuana outside in an appropriate environment, you won’t have to be concerned about the weather as much as you would otherwise. The weather, on the other hand, can still have an influence on your crop, particularly if there is an unseasonably warm period of weather. Lighting is critical for indoor farmers because it allows them to see their crops. While it may be tempting to utilize bright lights, too much illumination may cause the temperature in your grow area to skyrocket.
As a result, the temperature fluctuates often, causing mayhem.
The deadband is a temperature range of 3-5 degrees Fahrenheit surrounding the temperature that you have set the room’s thermostat at.
This aids in maintaining the proper temperature in the grow chamber.
4 – Good Drainage
Moving water is considered to be healthy water in the natural world since it flows in rivers, ponds, and rain. It is common for municipal water systems to have air shaken into the water, resulting in molecular oxygen becoming stuck inside the system. In stagnant water, on the other hand, the amount of molecular oxygen is decreased to the point where anaerobic bacteria may develop and thrive. It is normal for beginner growers to experience problems with standing water in their grow rooms. This water not only serves as a breeding habitat for germs, but it also releases moisture into the atmosphere.
As a result, sufficient drainage must be provided in the room in order to avoid stagnant water from developing puddles on the floor.
It is typical for producers to believe that they have achieved perfection in their humidity systems when this is not the case.
Rather than dealing with the most fundamental of concerns, such as standing water, they interfere with a sound system, causing even more problems.
5 – Use a Correctly Sized Dehumidifier
One would expect that acquiring a high-quality dehumidifier would be on the top of a grower’s wish list when it comes to purchasing new equipment. In fact, though, far too many people make the strange decision to cut corners and wind up paying twice for their mistakes. Is this something you would say? Residential dehumidifiers are inefficient in a marijuana grow room because they are not intended to manage the high levels of moisture present in the environment. Furthermore, they consume a great deal of energy and are quite inefficient.
- However, because to issues with humidity in their grow rooms, they are finally compelled to make a financial contribution.
- As a result, you must appropriately size a dehumidifier in order to remove the appropriate quantity of moisture from the air.
- Make certain that the system is designed in such a way that if one unit fails, the others continue to function normally.
- We hope you have found this information to be informative.
- As a result, they are more prone to bud rot than their sativa cousins when grown in humid environments.
It is possible to purchase a thermohygrometer that is both accurate and convenient. To summarize, in order to maintain proper humidity levels in your grow environment, you must do the following:
- Examine whether or not it is adequately sealed and insulated
- Maintain a specified temperature range and keep an eye on the illumination
- Increase the amount of cold air being supplied
- Watch out for the formation of stagnant water pools. Make use of a dehumidifier that is the proper size.

How to Get your Climate Spot On
It is not need to be difficult to manage your climate. Here’s all you need to know about the process.
The Ideal Climate
It all depends on what you’re growing, but as a general guideline, you should strive for the following results:
- 24-28 degrees Celsius (during the day with the lights on) or 22-23 degrees Celsius (during the night with the lights off)
- 70 – 85 percent relative humidity (RH) for propagation, 65 – 75 percent relative humidity (veg), 45 – 65 percent relative humidity (flowering)
- CO2 levels should be between 1000 and 1200 parts per million (ppm) for up to 40% quicker growth.
Air Exchange Vs. Closed Loop Rooms
Fresh air is drawn in to replace stale air, which helps to keep your temperature, humidity, and CO2 levels within reasonable limits.
- Your ability to influence outside conditions is limited. It is possible to experience climatic variations. Pests are a more serious concern. If you move a lot of air, it might be rather noisy.
The equipment you’ll require is determined on your setup.
- Equipment requirements are determined by your set up configuration.
- Equipment requirements vary depending on your set up.
Closed Loop Set Up
Closed loop growth environments are virtually fully shut off from the outside world. There is very little air entering and very little air leaving. However, instead of exchanging air, you continuously treat the air that is already there in your grow chamber. What’s the point? You will have comprehensive climate control (temperature, CO2 levels, humidity, and so on) while keeping pests and diseases out of your home!
- Plants thrive in their optimal climate throughout the year. There are no variations in temperature or humidity. Pests have a difficult time getting in
- CO2 concentrations at their optimum
- Growth has improved, and yields have increased.
There is no requirement for an air exchange system. As an alternative, you can treat the air that is already present in your grow room. You must do the very minimum in terms of cooling, heating, adding CO2, and removing humidity.
- HVAC (air cooling in the summer)
- Heating (in the winter)
- CO2 equipment
- The following items are included: humidifier, carbon filter (for odor elimination), air circulation fans, small extractor kit (for negative pressure filtration, which also serves as a power outage backup)
What you’ll require will be determined by the following factors:
- Your lights are on
- What is the size of your growing space? In addition to the time of year (in the hot months, more air needs to be evacuated)
As a general rule, the greater the number of lights in your home, the more efficient your air exchange system must be. When in doubt, it is always preferable to overspecify than than underspecify.
Extractor fans are used to remove air from your grow chamber. You’ll need one that can remove a sufficient amount of air. To figure out how much air it needs to remove, do the following:
Multiply the length, width, and height of your tent. The answer is determined by how much area is illuminated by your grow lights.
|In an XL BAY6 Tent: 1.2m x 1.2m x 2m = 2.88m 3 2.88m 3is the total area covered by your lights.|
Multiply this by 60 to get the answer. The amount of air you should remove per hour will be determined by this.
|In an XL BAY6 Tent: 2.88m 3x 60 = 172.8m 3 A100mm (4″) RVK100would do the trick!|
Step 3 (optional)
To be more specific, you can do the following:
- Add 20% if you have a warm attic
- Add 20% if you are using a carbon filter
- Subtract 15% if you have a cold basement
- Add 20% if you have extensive ductwork. For air-cooled lights, the reduction is 25-30 percent.
20 percent more for a heated attic, 20 percent more for carbon filters, 15 percent less for a cold basement, and 20 percent more for ductwork that is too lengthy. For air-cooled lights, the reduction is 25 to 30%.
Method 1 (easiest)
Use an intake fan that is 25 to 30% less powerful than your extractor fan, and make sure they are both running at the same speed.
If the intake and extractor fans are the same size (which is not advised), the intake fan should be run at a little lower speed than the extractor fan.
- South-facing rooms are often hotter than north-facing ones, therefore you may require a larger extractor fan in this situation. Please keep in mind that your fans should be situated at opposite ends of your grow room so that you don’t remove air that has just been sucked into your grow room. Purchase the larger of two available sizes if you’re torn between them
- Otherwise, operate the smaller fan at a reduced speed. To prevent your tent walls from being drawn into your fan, use Expando Tent Supports.
EC vs. AC Fans
EC fans are more expensive to purchase, but they are so much less expensive to operate that you may recoup the cost of the fan in less than a year. Over the course of five years, you’ll have saved up to £1,380! Fact. See for yourself how much number crunching we performed.
A fan speed controller is required unless you want your fans to operate at maximum capacity all of the time (which is something no one wants).
They adjust the speed of the fans or slow them down in order to maintain the desired temperature. You may select your minimum fan speed to ensure that enough air is removed to keep your CO2 level and humidity levels at a constant level. The type of controller you require is determined by your fan:
- AC fans require an AC controller, whereas EC fans necessitate the use of the same type of EC controller.
EC fans require an EC controller of the same brand as their a/c counterparts.

Aim for a CO 2 level of roughly 800ppm (vegetable) or 1200ppm (fruit and vegetable). This will allow for up to 40% greater growth (flowering). If you’re serious about reducing CO2 emissions, you should consider using an LPG generator or releasing Bottled CO2 Gas in a closed loop environment. However, utilizing MyCO2 Bags or TNB The Enhancer Cannisters, you may improve the quality of all grow rooms on a tight budget. Consider reading the’CO 2Generation Tutorial’ if you are considering incorporating CO 2.
MyCO2 Bags or TNB bottles
BothMyCO2 Bags andTNB are available. It is only when you activate the Enhancer Canisters that the CO 2 begins to be released. This implies that no CO2 is wasted during the transportation or storage process. Just make sure you have enough bottles or bags to cover the entire area where you’ll be growing:

Humidifiers And Dehumifiers
During the process of transpiration, plants naturally release moisture into the surrounding air.
If you have an air exchange system
Because your air exchange system removes humid air, you may not need to dehumidify your home. If, on the other hand, you discover that your humidity level is rising too quickly, calculate how much water your plants use in a 24-hour period and dehumidify by that amount. Checking your tank will allow you to determine how much water has been used. It is likely that you will require humidification at some time. It’s especially important during winter or when your body temperature is a concern.
If you have a closed loop set up
You will not be eliminating any of the moisture that your plants have produced. This entails two things: first, it suggests that
- Once the plants have produced enough leaf, it is doubtful that you will require the use of a humidifier. You will almost certainly require a dehumidifier (or an air conditioning system that can deal with humidity)
ALWAYS Use an RO Filter with a Humidifier
Once the plants have grown enough leaf, it is doubtful that you will require the use of a humidifier. The use of a dehumidifier (or an air conditioning system that can deal with humidity) will be mandatory.
How to Control Humidity in Your Grow Tent (4 Easy Ways) – Easy Guide
The most recent update was made on January 18, 2022. It is completely normal to use a grow tent to house a cannabis plant that is in the process of growing. The process of setting up a complete room such that it is suited for plants might be time-consuming and not really worth it for a tiny grow-op. However, due to the fact that a grow tent is a much more contained environment than an open space, there may be a few concerns that arise. The most pressing of them is the dilemma of how to regulate humidity in a grow tent.
If this is left unchecked, it might result in growth problems or molds that can destroy the plants.
A few aspects must be taken into account when preparing a grow tent for the cultivation of cannabis, as follows: Continue reading to learn how to reduce the humidity in a grow tent, boost it, and regulate it all at the same time.
How to Control Humidity in a Grow Tent
Because of a variety of factors, optimal air circulation in any grow tent is essential for the best results. Even with water molecules connected to it, hot air always climbs to the top of the atmosphere. As a result, our CO 2sinking is restricted to the bottom of the grow tent, behind the plant canopy, where it cannot be used. Fans are the most obvious option in this situation. Many people make the mistake of placing small oscillating fans at the top or sides of the room; however, they perform a poor job of blowing through the plant canopy and stirring up the CO2 at the bottom of the chamber.
They circulate the air, which aids in drying out the environment and transporting the beneficial CO 2 up into the plant canopy.
Once the fundamentals of air circulation have been established, the following stage is to determine how excessively humid air may be expelled from the grow tent. Fortunately, there are a plethora ofexhaust systems available that are specifically designed for this function. These function by removing stale, humid air from the grow tent through an exhaust vent and introducing fresh air into the tent through an intake vent, which should be located at the bottom of the tent. As the exhaust fan exhausts the air from the tent, fresh air is drawn in through an open intake port in the structure.
Many versions of exhaust fans may be programmed to only turn on when the humidity reaches a specified level, or to turn on and off on a simple timer.
The use of this method also aids in temperature regulation, while alternate methods may be required in especially warm or cold tents.
3. Air Conditioning
Because of the nature of the lighting system utilized in the grow tent, things can become really hot within it very rapidly. When specific conditions are met, the space becomes essentially a mini sauna. Portable air conditioners are the most effective alternative in this situation, albeit the size required may vary significantly depending on the size of the grow tent. A correctly sized air conditioning unit will not only cope with high temperatures, but it will also assist in extracting a significant amount of water from the air.
It is one of the most effective techniques to increase yields is to keep their environment somewhat temperate (in the 70°F to 80°F range) and consistent.
Things may get rather hot inside a grow tent, depending on the type of lighting system that is employed in the tent. When specific conditions are met, it’s like a tiny sauna in there. It is preferable to use portable air conditioners in this situation, albeit the size required may vary significantly depending on how large your growing space is. Temperatures will be handled perfectly by a correctly sized air conditioning unit, which will also aid in the removal of a significant quantity of moisture from the air.
Remember that cannabis plants prefer stable temperatures, and this is critical to remember. One of the most effective strategies to increase yields is to keep their habitat temperate (in the 70°F-80°F range) and consistent.

A Message on Insulation
No one of the humidity-control measures discussed above will be effective unless the tent is adequately insulated. When installing modifications such as exhausts or intakes, care should be given to verify that any holes are the right size for the tubing that will be utilized in the installation. A leaking grow tent may and will cause problems with humidity levels in the environment. Aside from the occasional gaping hole in the side of the tent, a well-constructed grow tent should have little issue allowing your tools to do the tasks for which they were intended.
Grow Room Control: Temperature, Humidity, VPD, and more
Grow room management provides you, the aspiring master grower, with what is unquestionably the single most significant advantage of indoor growing. It helps you get regular outcomes from your crops as well as predictable schedules and delighted consumers. You are able to do this because you have complete control over your environment; you make your own weather and are not susceptible to external factors like traditional farmers. At the very least, you should! Of course, you must be knowledgeable about what you’re doing.
What effect differing amounts of humidity, temperature, light, air movement, CO2 and other factors have on various objects.
All of the following environmental factors must be understood in order for your plants to flourish at their optimal potential:
- In the grow room, relative humidity refers to the amount of water vapor present. Atmospheric Temperature – The temperature of the air in the room, whether it is warm or chilly
- PPFD – The intensity of your grow lights that reaches the canopy
- PPFD – Movement of air throughout the grow chamber and among the plants is referred as as “air circulation.” CO 2Concentration – The total quantity of CO 2gas present in the air of your grow chamber, expressed in parts per million (ppm)
Depending on where you are in the plant’s life cycle, you’ll have different optimal levels to work with. For example, clones and seedlings require far greater Relative Humidity than fully developed plants that are ready for picking.
Grow Room Humidity Control
The optimal humidity level is proportional to the temperature. The higher the temperature, the greater the amount of relative humidity your plants will require in order to operate properly. Humidity, on the other hand, is affected by a variety of variables. Reservoirs that have been left open, spilt water, leaking faucets, leaking air conditioners, and even the plants themselves are all contributing factors. Water evaporates from the stomata of healthy plants, which is a process known as transpiration in the plant world (similar to how we sweat).
When humidity levels rise over a certain threshold, a plethora of problems become increasingly likely.
As previously stated, the optimal humidity is determined by the plant cycle and the temperature of the environment.
Grow Room Temperature Control
Temperature, like humidity, is crucial for the metabolism of plants to function properly. They don’t grow if the temperature is too low.
They dry out very soon if the temperature is too high. Many factors may influence temperature in a grow room, from the intensity of the heat emitted by your lights to the power of your air conditioner to the design of your grow room, all of which have an impact on grow room temperatures.
Grow Room Light Intensity
As previously stated, the PPFD is a measurement of the amount of light that reaches the canopy. It is possible that the chlorophyll in the leaves will be damaged if this value is exceeded. And that is really detrimental. Of course, if the soil is too acidic for the plant’s needs, the plants will not grow properly, or at all. Growers frequently want to provide their plants with as much light as possible since, after all, more light is better, right?! Not so fast, my friend. After a certain point, the law of decreasing returns lowers the efficacy of more light according to the law of declining returns.
Occasionally, the additional heat from the sun does more harm than good to the plant’s capacity to develop, rather than aiding it!.
Vapor Pressure Deficit Charts
A decent vapor pressure deficit chart (VPD Chart) can inform you the temperature and humidity ranges that are optimal for your situation. Often, this is dependent on the specific stage of development that your crops are in. When trying to optimize your grow environment for your plants, using one of these charts is the most straightforward method to establish a decent foundation from which to work. Depending on whether or not leaf temperature is being taken into consideration, multiple charts are available for download.
Check out our post on VPD and download a VPD chart that you can use to track your progress.
Grow Room Dehumidifiers
Dehumidification is frequently required in any grow room or green house due to the nature of how plants develop and the environment in which they thrive. Using strong blowers to interchange the air with outside air can be effective, but it can also cause problems with temperature and CO2 management. Dehumidifiers of the appropriate size are important for keeping the optimum humidity levels in your indoor grow room environment. They do consume a significant amount of electricity, similar to air conditioners in this regard.
Others, on the other hand, must be connected to an external control system.
Grow Room Temperature Control
Each 1000 watt light (with an uncooled ballast and bulb) will generate between 3,000 and 4,000 BTUs of heat, depending on the temperature. That means you’ll need an air conditioner that can keep up with the temperature of your lights. Controlling the air conditioning is similar to controlling dehumidifiers in that there are various options accessible.
Make certain that you purchase the greatest device that you can afford. Don’t scrimp and save money here. You will lose money if your AC is not dependable or is not correctly sized, as a result of bad crops and low harvest yields.
Grow Room Environmental Controllers
If you only have a digital thermometer and a hygrometer, that should enough. Make sure you pick a model that is trustworthy and has minimum and maximum readings. What you really need is a grow room controller, such as the Maxi Controller with Datalogger, which will not only manage the temperature and humidity of your grow room, but will also log the measurements into a USB flash drive, which you can then access on your computer later. TheMaxi Controller with Dataloggeris a fantastic piece of equipment.
When your grow environment or plants become excessively heated, the Maxi Controller may automatically reduce the lights or use a unique function known as Half Force to cool them down again.
Any seasoned grower will tell you that air conditioners and dehumidifiers are susceptible to failure.
Good air circulation can assist in reducing the number of microclimates in your grow room and distributing the grow room atmosphere more evenly. Mold and mildew problems will also be less probable as a result of this. In addition, it has the potential to enhance your plants! However, a few carefully positioned wall-mounted oscillating fans may make a significant difference. It may seem too wonderful to be true, but Obviously, excessive ventilation will be detrimental to the plants. Consider the sensation of a moderate breeze.
Prune Your Plants for Air Flow
Continuing the discussion of grow room air circulation, here are some additional resources. Under the canopy of your crop, overlapping and bunched-up leaves can create what’s known as micro-environments, which are essentially mini-environments within your crop. No matter how perfect the environment appears to be, if the leaves and branches are obstructing air movement, such places might be soaking wet at 90 percent humidity. In addition, the likelihood of mold and mildew developing in certain areas increases considerably.
Grow Room Light Intensity
Why did I wait so long to explain about how we design the lighting pattern in a grow room? After all, it’s something we all do when designing a grow room. Always keep in mind that we’re talking about the complete atmosphere of your grow room, and that most lights are dimmable these days. That dimming function is quite vital for ensuring that your plants develop to their full potential. As most of you are aware, tiny plants require less strong light than their larger counterparts. When the temps in the grow room get out of hand, it’s typically a simple matter of turning off the lights.
When planning the layout of your grow room’s lighting, it’s crucial to consider the power per foot of squared (PPFD) of the light source.
Make use of the table above to obtain a general sense of the sizes we propose for different types of rooms. Alternatively, you may use the DimLux Light Calculator to generate a thorough sheet on its own.
Grow Room CO 2Levels
The CO 2 levels in your grow area are also important to consider because healthy plants use a significant amount of CO 2 in the grow room. Now, this isn’t as efficient if you’re continually exchanging all of the air in your grow room, but it works well if you have an air conditioner and dehumidifier that can regulate the temperature and humidity in your grow room environment. An average PPM level of 1000 to 1200 PPM is sufficient; much higher than that and the law of diminishing returns takes effect.
Wrapping It All Up
The CO 2 levels in your grow area are also important to consider because healthy plants use a significant amount of CO 2 in the growing environment. If you’re continually exchanging all of the air in your grow room, this method isn’t as successful, but if you have an air conditioner and dehumidifier that can regulate the atmosphere in your grow room, this method is excellent. An average PPM level of 1000 to 1200 PPM is sufficient; much higher than that and the law of diminishing returns takes hold.
