How to Lower Humidity in Grow Tent When It’s too High
Home»Environment» The best way to lower the humidity in a grow tent when the humidity is too high 19187Views0 Humidity may be both a benefit and a disaster for an indoor grow system, depending on the situation. Just as with temperature, humidity has a significant impact on the quality and quantity of your indoor gardening harvest when it comes to quality and production. After everything is said and done, when the humidity in the grow tent rises to dangerous levels, it might result in the worst nightmare for a grower.
We hope you are not one of those people who would later come to regret spending all of their money, time, and effort because they were unable to deal with a scenario like this.
We’ve included both short-term and long-term solutions, as well as a list of causes that might result in damp air in the first place.
Why? Why? Why?
As a result, we’ve created a circumstance in which there is an excessive amount of humidity in the grow tent. The entire affair, on the other hand, did not happen out of nowhere. It must have had some cause for the high Rh level, and recognizing those reasons is critical to figuring out how to get the Rh level back down. Agreed? The following is a list of possible suspects:
The size of a plant’s leaves increases in proportion to the size of the plant. Furthermore, it is a fundamental principle of botany that bigger leaves release more vapor into the atmosphere. In the event that you do not adjust your ventilation system to the appropriate level, the humidity will rise instantly. This might also happen if you suddenly increase the number of plants in a container or garden.
Open Water Surfaces
Open water surfaces are a direct source of water vapor into the surrounding atmosphere. A nutrient reservoir, a moist floor in a room, or any other container of water can be used as a water storage container. If it’s in close proximity to an oscillating fan, the airflow across the surface will cause more water to evaporate, and then bang! The laws of thermodynamics are in effect.
Too Humid Outside Environment
The average humidity in Alaska is 77.1 percent, whereas the average humidity in Florida is 74.5 percent. The list goes on with the states of Louisiana, Mississippi, Hawaii, Michigan, and so on and so on. (The whole report may be seen here.) This discusses in great detail why growing in a grow room in these types of environments is difficult. Any small crack or leak in the insulation system between the grow room and the outside environment may result in a sudden and unexpected increase in the relative humidity.
The soil will get soggy as a result of overwatering the plants, which will also push the leaves of the plants to release more vapor into the air.
Both damp soil and over-transpiring plant leaves have the potential to make the environment inside the grow tent uncomfortably humid.
High Humidity is Bad, Here’s Why-
A lack of humidity in a grow room can have a variety of negative consequences for the plants. However, having too much of it is not a good thing. When your grow environment becomes overly humid, here are some immediate results:
- Unwanted biological development such as bud molds, powdery mildews, and other such organisms
- Having an excessive amount of moisture in the air may encourage bud or blossom rotting, which won’t be seen until you’re at the harvesting stage. First, by inhibiting the capacity of the plant to take up CO2, and then by restricting photosynthesis
- The plant’s ability to transpire further is hampered by vapor saturation of the air. This results in a drop in the total metabolic rate of the plant
- Plants prefer humid air while they’re young, and less humid air when they’re old, according to the USDA. If the plants continue to develop under high humidity as they mature, the rate of their growth and the quality of their health will be hindered.
How High is ‘Too High’ for Grow Room Humidity?
As we all know, the degree of humidity fluctuates from one development stage to the next. As a result, it is not possible to designate a definite “Rh Percentage” as a distinguishing factor between an optimal and an excessively high humidity level. However, the general rule of thumb is that the entire range of humidity in a grow room should be less than 60%. A rise in the relative humidity level above 60% can cause a number of crop-related problems, as we described in detail in the preceding section of this article.
The Correct Humidity Levels for Different Grow Stages
The plant’s roots begin to develop at this stage and will continue to grow for a while. As a result, a high amount of humidity is required. Humidity domes are frequently used to raise the relative humidity (RH) of the approaching air above the plants.
Vegetation: Rh 40-60%
Because growing plant leaves need a sufficient amount of water in the air, the humidity level must be elevated. Additionally, a percentage of the water intake is accomplished through the roots of the plants. However, because they haven’t fully formed yet, leaves must continue to take in water.
Flowering: Rh 35-50%
This is the point at which high Rh begins to manifest itself in negative ways. As a result, it is critical that the humidity does not rise from this point on. Molds, rotting buds, and other unpleasant things will begin to appear if this is not done. To ensure that the flowering stage begins successfully, the relative humidity should be maintained between 40 and 50 percent. However, after the buds begin to produce a crop, farmers reduce the percentage to 35-40 percent. And this must be done gradually, so that there is no significant, rapid decline in the Rh.
Crops begin to dry at this point, which leads to the harvesting of the crop. However, we must maintain a humidity level of 30-40 percent in order to prevent the buds from drying out too quickly. Some growers prefer to maintain a little higher humidity level (50 percent) in order to allow their buds to dry more slowly. This, in any case, enhances the overall quality of the cured buds.
|75-85% Rh||40-60% Rh||35-50% Rh||30-40% Rh|
How to Decrease Humidity in Grow Tent/Room?
When it comes to figuring out how to reduce humidity in a grow room or room, things aren’t always easy to cope with. Any action will require sufficient time to bring the Rh down. As a result, you must stick to the shortest routes available. The few of solutions that we’re about to cover are designed specifically for circumstances like this. Here’s everything you need to know-
Use A Dehumidifier
It should go without saying that in order to reduce humidity, you will need to rely on our trusted ally, the grow room dehumidifier.
Prior to purchasing a dehumidifier, take a moment to consider the appropriate size for your grow room layout before making your purchase. So, what exactly qualifies as a decent dehumidifier that can remove the exact amount of humidity that you require? Some points to think about are listed below.
- Dehumidifying capacity is critical, and it should match the requirements of your grow system exactly. According to the manufacturer, it is intended to absorb and expel the same quantity of vapor that your plants exhale via their leaves. There is a limit to how much may be held in a pint
- You should check to see that your dehumidifier can be connected to your drainage system if you live in a humid climate. It should have a water tank that is enough in size. It should be equipped with an automated timer or an automatic shut off mechanism (when the tank is completely full)
- It should be considerate of the power bills’ budget.
Once you’ve selected the appropriate size dehumidifier, you’ll need to ensure that it is installed in the proper location. Also, avoid connecting these dehumidifiers to electrical extension cords if at all possible. The following is our preferred dehumidifier for the grow room: GDM30 from Ivation The following is our preferred dehumidifier for the grow room: hOmeLabs Dehumidifier for 1,500 square feet that is Energy Star rated
Use An Air Conditioner
Knowing that the temperature and humidity of a grow room are intertwined is not a surprise. When the temperature rises, the capacity of the air to contain water vapor increases as well, and you will see a direct increase in the Rh levels in your room. As a result of decreasing the temperature, you will be able to eliminate a significant amount of humidity from your grow tent or growing environment. Having said that, selecting the appropriate size of air conditioning units is critical. Otherwise, it will either result in condensation or will be unable to maintain control over the temperature and humidity levels in the room.
When it comes to smaller grow systems, such as 44, 55, and 88 grow tents, utilizing a dehumidifier or air conditioner is not a suitable alternative for reducing humidity. Fortunately, there are a number of passive solutions that are effective in dealing with this problem in indoor grow systems. We’ve compiled a list of three actionable passive methods for accomplishing this. Take a look at this-
Boost the Ventilation Up
When it comes to passive methods of decreasing the humidity level, increasing air circulation is at the top of the priority list. One of the primary reasons of excessive humidity buildup in your grow room is the failure to properly vent damp air out at a sufficient rate. Simply said, substituting the humid air for fresh, ambient outside air will lower the Rh percentage by a significant amount. In the event that you find yourself in a high humidity condition, the following steps should be taken to improve ventilation:
- Increase the size of your intake hole or make a new one. This will allow for more air to enter the room while also increasing the efficiency of an exhaust fan. If you want to utilize an intake fan instead of holes, increase the power (CFM) of the fan. Instead of simply employing oscillating wall fans to circulate air around the grow room, adding floor fans as air circulators throughout the grow room is a good option. These fans have the ability to draw air through the plant canopy, ensuring a proper interchange of old, humid air with new, dry air. Make use of an atmospheric controller that has humidity settings to reduce the risk of fire. It will automatically adjust the exhaust/inlet fan speed in accordance with the relative humidity in the room
- And In responsible of removing the humid air should be inline fans. Make certain that the fan is strong enough and has the same diameter as your ducting, which is more critical. Keep a watch out for how effectively this buzzy thing is at reducing its noise level
Use A Thermostatically Controlled Block Heater
Do you have a high level of humidity in your grow tent at night? Increases in Rh levels and condensation are more likely to occur during the dark hours as opposed to the light hours, according to research. The temperature decreases as soon as the lights are turned off. When the temperature drops sufficiently, moisture will begin to accumulate around the lights, which is referred to as humidity fluctuation in this context. Remedy? When the lights in your grow room are turned off, use a thermostatically controlled block heater to keep the temperature near to the level when the lights are turned on.
Defoliate the Plant Leaves
We’ve already noted that when plant leaves develop in size, they become a more significant source of water transpiration into the surrounding atmosphere. Result? The humidity in the grow chamber rises quickly. You can defoliate some of the exceptionally huge plant leaves as a passive solution for bringing the humidity level in the grow tent down.
Whenever you are removing leaves, make sure to leave enough for the plants to continue their usual operations, such as photosynthesis. By comparison, it is a relatively inexpensive method of lowering humidity in grow tentas that works fairly well.
Things to Do to Avoid Further Raise in Humidity
What can I do to permanently reduce the humidity in my grow tent? Here are some steps you may do to keep the humidity in your ingrow tent from rising any further:
Don’t Depend on One-dimensional Ventilation
One of the fundamentals of humidity control is that, if appropriate ventilation is provided throughout the grow room, the air will never get saturated with water vapor. The oscillating fans alone will not be sufficient to ensure that this occurs. Because they can only lower the temperature of the plant canopy, they are not very effective. So, what is the best way to create a multi-dimensional ventilation system? As a result, here are some recommendations: –
- If you’re growing in a tent, make sure there are many intake holes. In the event of a room, source air should be provided by more than one intake fan. Maintain appropriate air circulation across the plant canopy, including the bottom (with floor fans) and top (with wall-mounted oscillating fans) sections. Allowing the CO2-rich, heavy air to accumulate on the floor is not recommended.
Deduce Exposed Water Surfaces
It’s a very easy and inexpensive hack to do, but it turns out to be really successful in terms of lowering the humidity in the grow room. And that is to determine whether or not there are any exposed water surfaces in the grow chamber. How did these open water surfaces get there in the first place?
- Water that is stagnant yet does not puddle on the ground
- Reservoirs for water
To deal with the first, you must make certain that a sufficient drainage system is in place throughout the whole grow system. For the second, just place covers over each and every water reservoir you have in the room to bring the situation to a close.
Insulate Your Grow Space from Outside Humidity
Occasionally, you will notice that the humidity level continues to rise regardless of how much effort you put out after placing it down. Perhaps this is due to the fact that your indoor garden is in close contact with an excessively humid outside environment. It’s possible that the location where you reside has more humidity than usual, just like it does in New Mexico or Colorado. Commercial growers frequently utilize barriers such as foam insulators and other similar materials to prevent this from occurring.
Use Soil That Absorbs Vapor
The use of soil that can absorb water and retain the Rh beneath the grow tent can be a useful step in eliminating humidity in the grow tent. Sandal soil is an excellent example of this type of soil. Make certain, however, that your plants will not have any difficulties growing in such mediums.
Use The Right Size of AC Units
Both big and undersized air conditioning systems have the potential to cause an increase in temperature and humidity. With large air conditioning machines, the dead band is quite brief, resulting in an increase in humidity in the surrounding air. And, on the other side, small air conditioning systems cause wilting, which is a concern for indoor plants. One of the factors that might cause a troublesome environment for the plants is a high degree of humidity. What’s the gist of it? Always make sure that the air conditioning units are the proper size so that they can operate consistently for the greatest amount of time.
Keep an Eye on Your Humidity Level
Using this method does not constitute a ‘prevention’ to lower humidity in a grow tent. However, by utilizing a hygrometer, you can keep track of the exact humidity level that your tent or room is experiencing. In the market, there are thermometer-hygrometer combos that may be purchased.
You can kill two birds with one stone if you have one of them hanging on the wall of your grow tent. To ensure that the humidity in your grow tent does not get too high, here are some of our favorite digital thermometer-hygrometer combos.

How To Lower Humidity In A Grow Tent (Without Spending A Ton)
Plant maintenance and growth is a combination of art and science. This is also true in the case of cannabis production. As you get more experience in the field, you will have a deeper understanding of the ‘art’ component of the equation. The same may be said for the’science’ component of the test. However, in contrast to the arts, you may research science and truly get it right from the beginning. When it comes to the science of cannabis cultivation, heat and humidity are two of the most significant aspects to consider.
It is your responsibility to keep those levels up.
Today, we’ll look at one part of this: what to do if the humidity in your home is excessive.
How To Lower Humidity In A Grow Tent
Cannabis is not a fussy plant in the least. It can thrive in a wide range of environmental conditions. However, if you provide it with the optimal circumstances, it will reward you with far larger and higher-quality harvests. Even the most ideal conditions aren’t important to the plant, which doesn’t have a preference. It prefers a comfortable room temperature and average humidity. So there’s nothing exceptional here. The optimal temperature and humidity levels, however, do alter as the plant matures and becomes more established.
Different Growth Stages Need Different Humidity
Humidity levels should be increased throughout the early stages of growth to ensure proper development. During this period, plants thrive under excessive humidity. However, as plants progress through their development phases, the humidity level needs to be reduced. The optimal humidity values for each stage of plant development are listed below.
- The percentage of seedlings and early vegetables is 70 – 75 percent, the percentage of vegetables is 50 – 70%, and the percentage of flowers is 40 – 50%.
In most cases, you won’t have to worry about lowering the humidity while you’re relaxing. In fact, depending on your location’s temperature, you may need to take efforts to enhance the humidity in your grow tent. However, during flowering, this changes. You may find it difficult to keep the humidity levels down during the day. Unless, of course, you continue reading. Then you’ll be able to figure out exactly what to do. But first, let’s take a quick look at why it’s important to maintain humidity levels under control.
Why Lower Humidity In Your Grow Tent?
Mold, fungus, rotting buds, and mildew can develop in your grow tent as a result of high humidity. It even has the effect of slowing the development of your plants. The most prevalent is a condition known as bud rot, which is comparable to the grim reaper for plants, appearing in your grow tent and wreaking havoc on your plants. It appears as a white powdery material at first, then becomes gray, and then becomes black as it matures. If your buds become infected with bud rot or powdery mildew, they are rendered unusable and must be discarded.
What does bud rot have to do with decreasing the humidity in a grow tent?
However, bud rot and other forms of mold and mildew aren’t the sole culprits in this case. Aside from the external reasons, there is an internal cause for wanting to limit the moisture content of the air from becoming excessive.
Internal Health Effects Of High Humidity
External factors such as bud rot and the mold and fungus that might develop as a result of excessive wetness are not the only possible difficulties. There is also the possibility of an interior issue developing. If the air is saturated with moisture, your plants’ roots will not be able to absorb as much water as they should. The nutrients required by your plants will be depleted if your plants do not drink enough water from their roots. Nutrient insufficiency leads in buds that are less powerful and more unhealthy.
Lowering Humidity In A Grow Tent
The good news is that lowering humidity levels is not that difficult to do. However, there is a good probability that you may have to spend some money. You will almost surely want at the very least a ventilation system, and maybe even an air conditioning unit or a dehumidifier. You’ll need ventilation and maybe air conditioning anyhow to keep the temperature under control, so it’s not really an extra expenditure. Dehumidifiers, on the other hand, are not pricey.
Get A Dehumidifier
Wouldn’t it be great if science could come up with a machine that was particularly intended to remove moisture from the air, and all you had to do was plug it in and walk away from it? Well, such a remarkable gadget does exist, and you can find it at your local home improvement or medicine shop. You may also purchase one online, such as this one (good for a small tent). A dehumidifier is the most straightforward solution to the problem of excessive humidity, but they may be expensive if you have a large tent or a large room.
Commercial Grade Dehumidifiers
If you have a large company or if you are doing this for a living, you should definitely consider investing in a commercial-grade dehumidifier right away. Even if the little ones designed for everyday use are ideal for small tents and hobby growers, they do not let you to regulate the humidity level. They can only be turned on or off; there is no in-between. While this is sufficient for the majority of individuals, it is insufficient when there is a considerable amount of money at stake. It is possible for a commercial grade dehumidifier to continuously measure and adapt its operation depending on whether it needs to remove moisture or whether it needs to rest and let the water vapor to gather.
If you are not concerned with the ability to’set it and forget it,’ or if you have a small company, you will not require a commercial dehumidifier to meet your requirements.
Ventilate Your Grow Tent
If you can get fresh air into the tent from the outside, this can assist to reduce the humidity, provided you do not reside in an exceptionally humid climate zone. Of course, if you’re going to be bringing in fresh air from the outside, you’ll also be exhausting air from within the tent, so plan accordingly. In fact, with tiny tents, all that is required is that you blow air out of the tent. In order to compensate for the negative pressure created, additional air must be drawn in. In order to exhaust the air in your grow tent, you’ll need a good inline fan for it.
Because humid air is heavier than dry air, if humidity is a significant problem but temperature is not a significant one, you can consider installing an exhaust fan at a low setting.
By leaving greater space between the plants, you may also improve circulation among the plants themselves.
As a result, there is greater space for air to circulate, and the lower branches do not form buds in the first place. You will have a greater yield if you do not use them. Make certain you simply utilize the best weed trimming scissors available. The bad ones will not cut neatly as they should.
Do Not Water More Than Necessary
Overwatering your plants will almost always result in issues. When your plants receive too much water (particularly in areas with poor drainage), it can lead to nutritional deficiencies and root rot, which can cause them to become anemic and sickly. Excess water also contributes to excessive humidity in the air. When it comes to watering your plants, make certain that you are following scientific principles. A much of water might be detrimental to your plants’ health. As a result, you are included.
How Much Water Is Too Much?
This is a subject that warrants its own book (and there are already a plethora of them available!). However, because it is important for minimizing the humidity in your tent, we will go through the fundamentals here. This might vary greatly depending on your growth medium (soil or other types of media) and drainage system. As a general rule, you should water your plants until the soil is well saturated, then allow the soil to dry completely before repeating the process. Assuming you have normal soil with adequate drainage and growing pots of moderate size, this amounts to one thorough watering every 2-3 days.
There is a general rule of thumb that can be useful to you.
The aim is to totally soak your plants on a regular basis rather than watering them only a tiny bit every day.
In addition, it almost certainly causes the air to become excessively humid.
Lower Grow Room Temperatures
Relative humidity and temperature go hand in hand. Temperatures that are higher than ideal are acceptable as long as the humidity is lower than ideal. And vice versa. This means that you can, in essence, compensate for higher than ideal humidity by maintaining lower than ideal temperatures. That said, this is really only a good idea if you just can’t seem to get those humidity levels down. It is much better to actually lower the humidity and keep the temperature where it should be. But if your temps are too high and that is the reason for your humidity problems, definitelycool your grow tent!
Consider An Air Conditioner
The most convenient method of lowering temperatures is to use an air conditioning unit. As previously said, not only is this a crucial element of maintaining the health of your plants, but it is also a simple and effective approach to reduce the relative humidity in the air. It is possible to purchase units that stand alone or are on wheels, removing the requirement for them to be permanently fixed to the wall. This is ideal for use in tents. They have an exhaust tube that has to be routed out of the tent via an aperture in the side of the tent.
The ability of the air to contain water will be reduced as a result of cooling it and circulating it around the room. The colder the air, the less’space’ there is for water to live in its natural environment.
Lower Grow Tent Humidity: Final Thoughts
Higher humidity levels are ideal for vegging, but during flowering, and especially during the later stages of blooming, you must substantially reduce the amount of moisture in the air to ensure a successful harvest. Not doing so will result in a less productive (and, in some cases, wholly unproductive) yield. There are a variety of approaches that may be used to reduce the humidity in your grow tent, but the most effective are enough ventilation and optimal circulation. It’s also crucial to keep your body temperature under control.
How to Lower Humidity in Grow Tent When It’s too High
Because I am an Amazon Associate, I receive money when people make eligible purchases. You will not be charged any additional fees! The growth of plants necessitates the use of water. It is believed that humidity is a component of the water taken in by plants through their leaves and stems. Humidity levels, on the other hand, must be maintained at their optimal levels at all times in order for plants to grow. When it is too low, your plants will suffer as a result. In addition, when the humidity rises over a certain threshold, they have difficulty surviving.
But first, let’s go over some of the most crucial factors you should be aware of when it comes to humidity.
What Exactly is Humidity?
Allow us to be a little more specific. Humidity is defined as the amount of water contained in the air in the form of vapor. You will also learn about relative humidity throughout this presentation. It simply refers to air that has become completely saturated with water vapor and is unable to retain any further water. The relative humidity of the air must be kept at a specific level in order for plants to grow. If the humidity level surpasses the acceptable levels at any point throughout the growing process, your plants will not produce as much as you want.
The Right Humidity Level For Your Grow Tent
Plants require varying degrees of humidity at different stages of their life cycle. In each stage of growth, water is required in different amounts, which results in a distinction. As a result, make sure that your humidity is constantly within the following ranges at all times. Temperature Range: 70 to 75 percent Humidity Level at Seedling Stage Plants are in the process of developing at this time. The roots of the plant are unable to receive sufficient water for the plant. This is why you require additional moisture.
- Having a high humidity level will assist the plants in thriving as all portions of the plant develop and thrive at the same time.
- However, in order to maintain the fast rate of development, they will require additional water from the surrounding environment.
- Humidity levels should be between 40% and 50% throughout the flowering stage.
- Molds and mildews will not grow around the blooms if the humidity is kept at a moderate level.
Humidity levels between 45 and 50 percent throughout the harvesting stage. In order to prevent the produce from becoming brittle and harsh during the harvesting stage, it is necessary to maintain an average level of humidity.
Why Optimum Humidity Matters
As we have previously established, a specific degree of humidity in the air will be required at all phases of your plant’s development. This implies that if the humidity is not maintained at its ideal level at any point throughout the growth cycle, the plant will not flourish at that period. As a result, it will eventually have an impact on all of the previous phases. When the humidity is at its highest level, plants employ their leaves to absorb water and transport it to their internal systems.
- As a result, the roots are less able to absorb water.
- When this occurs, the plants begin to suffer from mineral shortages as a result.
- Plants grow healthier, stronger, and more leafy when the humidity in their grow environment is at the proper level.
- Additionally, maintaining optimal humidity helps to keep mold from attacking your plants.
Simple Ways to Lower Humidity in Grow Tent When It’s Too High
1. Provide Adequate Water This is the first topic we’ll be talking about. If you want to receive the best yields possible from your grow tent, you must avoid overwatering them. It is the most straightforward method of preserving your plants from excessive dampness. When plants are overwatered, they take up a large amount of water and retain it. It is through their breathing that they expel the extra water into the atmosphere. As a consequence, the humidity in your grow tent is higher than you had anticipated it to be.
- When the water evaporates, it causes the same problem as before – a high level of relative humidity.
- We’ve already discussed that plants require varied degrees of humidity depending on their stage of development.
- This is due to the fact that various stages will need varying degrees of humidity.
- Plants that have reached maturity have begun to produce leaves.
- Because of this, they are able to raise the humidity levels in the grow tent.
- The goal here is to make sure that all of the plants in a grow tent are at the same stage of development as one another.
Explore the area around the grow tent.
Remove any surplus water that may have accumulated in the grow tent.
When the temperature rises or when air blows over them, the water in trays and jars evaporates.
This will result in a two-fold dilemma.
Empty water reservoirs and flush stagnant water out of the system.
It is possible that you will not need to remove the water supply points at all.
Try to minimize the possibility of water evaporation to the greatest extent possible.
Make use of soils that are easily permeable to water.
Every one of these distinct kinds of soils has a varied capacity for retaining water.
Sandy soil, on the other hand, has a high rate of water drainage.
In most farming situations, loam soil is preferable above other types of soil.
As a result, clay soil should not be used in your grow room.
It is recommended that you purchase loam soil.
Sand soil, on the other hand, is recommended if you want to drain a lot of water.
Make sure that your grow space has appropriate airflow.
At the same time, you must make certain that the grow chamber is always supplied with fresh, low-humidity air.

How to Lower Humidity in Grow Room Set Up
Anyone who has grown cannabis will tell you that the most crucial component in producing high-quality cannabis flowers is maintaining consistent temperature and humidity. Climate, which is composed of temperature and humidity, is the single most important variable influencing density, potency, and overall cannabis yields. In the past, we’ve spoken about how young plants and clones require greater levels of humidity. However, as the adage goes, they don’t stay youthful indefinitely. The development of a plant’s roots signals the beginning of the three subsequent plant cycles: Vegetative, Flowering, and Late Flowering.
In order to ensure optimum nutrient uptake, mold and fungal avoidance, as well as improved resin growth on your colas, you must gradually reduce the humidity in your growing environment.
|Stage of Growth||Humidity||Lights-On Temperature|
|Seedling Stage||65-70%||68-77 F°|
|Late Flowering||30-40%||64-75 F°|
*Decreased by 5% every week until the right levels are achieved.
What Is Humidity?
It is truly “Relative Humidity” that we are referring to when we talk about relative humidity (RH). Water vapor concentration is a comparison between the quantity of water vapor present in the air and the amount of water vapor the air could store at a certain temperature before it turned into moisture. Warmer air can store more water vapor than colder air, and this is the most crucial thing to remember about air temperature. Because of this, as the temperature lowers, fog forms: even if the water vapor levels stay constant, the lower temperature allows for less water vapor suspension, resulting in fog formation.
Because relative humidity (RH) is a measure of humidity in relation to temperature, increasing the temperature while maintaining the same water vapor levels reduces relative humidity.
The alternative method of adjusting relative humidity is to increase or decrease the amount of water vapor in the air while maintaining constant temperature.
Remember that raising or decreasing temperature has an opposing response on relative humidity (temp up, RH down | temp down, RH up), but altering vapor levels at a fixed temperature has no direct effect on relative humidity (temp up, %RH up | temp down, %RH down) (vapor down, RH down, etc.).
Assuming you have your temperature under control with adequate ventilation and cooling, let’s have a look at what we can do to manage humidity levels in order to produce the ideal environment for healthy cannabis crops. To understand how to regulate humidity, we must first understand where it is coming from and why it is there. The relative humidity levels of the external air that is vented in will be different from the inside air. This will change depending on the place, the season, and even the day.
In the last instance, any standing water in your grow chamber will evaporate into the air, increasing the amount of water vapor in the air.
This is especially true when taking into consideration how tough it may already be to maintain acceptable temperatures when dealing with dozens of 1,000 watt bulbs and the heat they emit.
You’ll need a dehumidifier to accomplish this.
Why You Need a Commercial Dehumidifier
Many first-time growers are aware of the need of controlling humidity levels, but often make the error of attempting to save money on this critical piece of equipment. Consequently, instead of purchasing the appropriate instrument for the task, they purchase a dehumidifier meant for household use, which is by design inefficient when compared to the amount of work it is performing and simply isn’t constructed to manage the burden. Get a commercial-grade dehumidifier if you’re planning any big growth projects.
- Choosing to jump a few pages ahead and getting it done correctly the first time with a business dehumidifier is another.
- No matter how hard you try, humidity levels will not miraculously decrease on their own.
- if you put in the effort to make them great.
- To further maintain consistency, make sure you incorporate redundancy into your grow room design from the beginning to the end of the process.
There is nothing more frustrating than having the most critical piece of equipment fail at the most inconvenient of times. In fact, if Murphy has taught us anything, it is this: nothing is impossible. Dehumidifiers,Grow Room Setup are some of the topics covered.
9 Effective Ways: How To Lower Humidity In Grow Tent?
The plants in Mark’s grow tents had developed an abnormal growth pattern one day when he returned from work, and Mark spotted it. He discovered several plants that had powdery mildews and bud molds, as well as those that had rotting blossoms. He couldn’t believe what he was seeing. What was the source of Mark’s difficulties? Mark, on the other hand, is not alone. Every year, thousands of people are confronted with the same problems. These kind of difficulties in agrow tent are believed to be caused mostly by extreme humidity, according to industry experts.
They were able to accomplish this just by efficiently managing the moisture in the tent.
After reading this article, you will have a good understanding of why it is necessary to minimize humidity, what generates a humid atmosphere, and how to deal with excessive humidity levels.
Why Lower Humidity?
First and foremost, we must define what humidity is. Ordinarily speaking, humidity refers to the amount of water vapor present in the environment. Humidity is not in and of itself a bad thing. When the temperature rises over a certain threshold, it poses a hazard to tent planting. The recommended temperature and humidity for growing tents are 20-30 degrees Celsius and less than 70% relative humidity, respectively. The following are some of the hazards of excessive moisture:
Pests And Diseases
Pests and bacteria are attracted to high humidity, which results in illnesses such as bud molds and powdery mildews. Solving humidity concerns is a common solution to these difficulties.
Effect On Metabolism
Excessive humidity impairs a plant’s capacity to absorb carbon dioxide from the air. As a result, the plant is unable to perform proper photosynthesis, which has an impact on the plant’s entire metabolism.
Rotting Of Buds And Flowers
Humidity levels that are too high pose a serious hazard to plants. It causes damage to portions of the plant that are relatively fragile, such as buds and flowers. High humidity grow tents are notorious for causing bud rot and bloom rot, which can be fatal.
Inhibit Growth Rate
The ability to effectively manage humidity is essential for the optimal development of plants. The growth rate would be unsatisfactory if moisture could not be controlled adequately.
Low Water Intake Of Roots
There is already an enough amount of water vapor in the highly humid air. As a result, plants are unable to evaporate the water. They have a tendency to consume less water than is necessary.
Low Plant Yield
Plants are unable to carry out their normal metabolic processes when the humidity level exceeds the optimal range. This has an impact on the results of plants. One of the most significant objectives of any planting is to produce a high yield of goods. As a result, it is critical to maintain an appropriate humidity level.
What Causes High Humidity?
Before we can figure out how to minimize humidity in a grow tent, we must first figure out what causes excessive humidity.
The following are some of the most common reasons of excessive humidity:
While it is necessary to water plants as they are developing, overwatering may be extremely detrimental. It can sometimes cause the soil to become more moist than usual, which increases the amount of humidity in the air.
Free Water Surfaces:
Water surfaces exposed to the elements are a direct source of humidity. As water evaporates, the surrounding environment becomes more humid. If there is a water pot, you should make sure it is covered.
Transpiration is a natural mechanism in which plants exhale water vapor into the atmosphere to cool themselves. Water is taken up by plants from the soil. In addition, it makes the air more humid.
Despite the fact that grow tents are not attached to the ground, the surrounding environment has an impact on grow tent plants. The humidity in grow tents tends to be high when the surrounding environment is humid.
No. Of Plants:
Humidity is increased when there are too many plants in a limited place. When planting, it’s important to keep in mind how many plants you’ll be putting in your grow tent.
Size Of Grow Tent:
Large grow tents do not become as humid as tiny grow tents because of their size. It also boils down to the number of plants you are cultivating in a given space.
Effective Ways: How To Lower Humidity In Grow Tent?
In order to minimize humidity levels, we must first address the underlying reasons of high humidity. We will not all be confronted with the same kind of issues. You must first determine the nature of the position you are in. Follow the recommendations and learn how to regulate humidity in a grow tent. However, if you are interested in a low-cost method of lowering humidity in a grow tent, please see this link.
Do Proper Ventilation
Increased ventilation will help to reduce humidity levels in the environment. The tent’s ventilation system ensures that the trapped air within the tent has a connection with outside air. Airflow may be achieved by the use of fans.
Do Proper Insulation
You can reduce humidity levels by ensuring appropriate ventilation. Ensures that the trapped air within the tent is exchanged for fresh air through the use of venting systems Airflow may be achieved by the use of fanning.
Use Air Conditioners
Air conditioners may improve the quality of air and make it low humid. If you’re going to be in an area with excessive humidity, make sure you have an air conditioner. Purchasing an air conditioner, on the other hand, is expensive. However, it has the potential to provide the desired consequences.
If you routinely experience excessive humidity, a dehumidifier is the best option for you. Many different types of dehumidifiers for grow tents are available on the market. They are available in a variety of sizes and powers. You must choose the one that is the most appropriate for the size of the grow tent.
Remove Stagnant Water
The presence of a stagnant open water source will raise the relative humidity in the tent. As a result, in order to minimize humidity, you must eliminate free water sources.
Apply Water-Absorbent Soil
There are many different types of soils available on the market that absorb water. When these soils are applied to plants, the humidity will be reduced. As well as promoting plant growth.
Reduce Plant Density
Because of the high density of plants, there will be a lot of dampness.
As a result, in order to lessen humidity levels, you must limit the number of plants in a grow tent.
Control Overheating Lights
The usage of lights that generate heat might cause temperatures in the tent to rise significantly. It is necessary to regulate the temperature in order to regulate the humidity.
Vapors are released in greater quantities by large leaves than by little leaves Occasionally, removing the bigger leaves might help to reduce humidity. Growing plants in grow tents is a delicate process that requires great care. It necessitates extensive and time-consuming efforts. High humidity has the potential to undo all of your hard work. As a result, it would be beneficial if you gave this topic your whole attention. If you know how to reduce the humidity in a grow tent, you will have a big advantage over others.
- Then you have to figure out what the primary factors are that are generating the excessive humidity.
- However, if they do not function well, you must be prepared to spend money on a humidifier or an air conditioner.

9 Best Cheap Way To Lower Humidity In Grow Tent
As a horticulture enthusiast, I make it a point to surround myself with as much greenery, plants, flowers, and so on as possible. I had the idea to grow my favorite plants in a grow tent inside my house just for the heck of it. However, there was a danger when the humidity in my expanding tent began to rise. Then I employed several simple and inexpensive measures to lower the humidity in my grow tent, which were both quick and effective. If you have ever found yourself in a position like this, you will undoubtedly be interested in learning about the inexpensive methods of lowering humidity in grow tents.
Take my word for it!
Why Lowering Humidity?
Humidity arises when the presence of water molecules in the air is detected. If the humidity in your grow tent is greater than normal, your plant’s health may be compromised, its development may be stunted, fungus may be present, and mildew and mold may also develop as a result.
What High Humidity Causes To Your Plants?
Humidity is the condition of air when there is a significant amount of water vapor or steam present, which eventually results in condensation. Humidity levels that are too high or too low are both detrimental to the health of a plant in your grow room. It is possible for your plant to develop slowly if there is too much humidity, and it may get drier or dehydrated if there is too little humidity.
Because of this, it is critical to regulate the humidity level in the grow tent and maintain it within the range recommended by specialists. Nine of the most inexpensive methods for lowering humidity in a grow tent are presented here.
What Is The Perfect Humidity Range For Grow Tent?
The humidity range for a grow tent varies depending on what you are going to grow in the grow tent. Among seedlings, the percentage ranges between 70 and 80 percent. For vegetable growth, it ranges from 45 to 65 percent, and for floral growth, it ranges from 40 to 60 percent. Learn more about the appropriate temperature and humidity for a Grow Tent in this detailed guide.
How To Control Humidity In Grow Tent
For a grow tent, it is expected that the humidity level should be between 40 and 60 percent. If you want your plants to develop in a healthy manner, you should not surpass this proportion in your grow tent. But how can you keep it under control? Well! If you follow these steps, you will be able to manage the humidity in your grow tent.
- Make certain that there is enough air ventilation. Maintain a drainage system to ensure that no water is trapped in the system. Make use of a dehumidifier for grow tents that is of the highest possible grade
- Keep an eye on the illumination

Cheap Way To Lower Humidity In Grow Tent
It is critical to lessen the humidity in your grow tent or to maintain correct humidity levels, and it is equally critical to do it at a reasonable cost to ensure success. Listed below are nine low-cost methods for lowering humidity: 1. Using Damp Rid, you can get rid of mildews and molds on your plants while also absorbing excess moisture from the air. DampRid just eliminates the extra wet air that surrounds it and does not dry it out. As a result, more than one container will be required for a bigger grow tent.
- When bicarbonate soda is dampened, it releases carbon dioxide into the air, which is beneficial to your small plants in the long run.
- How are you going to keep it up?
- If you install fan systems within your tent, whether they are exhaust fans or any other type of fan that pulls air from the outside, you can ensure that the tent is well ventilated.
- The removal of stagnant water from the growtent floor is always preferred above other options.
- Plants naturally emit carbon dioxide, which actually increases the amount of moisture and humidity in the air.
- What should I do?
- Make sure it isn’t too thick.
- Overwatering does not imply that your plant will develop more quickly.
Overwatering the plants might be detrimental to their health. Because too much water surrounds the roots, they are unable to absorb oxygen and nutrients necessary for the plants to grow and thrive. Overwatering can also be detrimental to your plants’ health.
Another approach for decreasing humidity in a grow tent is to incorporate air holes within the structure. It makes it possible for the air to travel freely. Because the air does not become trapped inside the grow tent, there is no condensation inside the grow tent as a result. If you want to create a thick barrier between the outside territory and inside of your grow tent, you may use foam isolation in your tent. It will protect your plants from any external hazards that may cause harm to them.
It is also important to ensure that your plants are adequately insulated in order to reduce dampness.
The temperature is raised by the growlights that we normally use in our grow tents.
When we nurture a plant for our enjoyment, we want it to be as comfortable as possible. In order for the plants to develop properly, it is critical to maintain all of the components. We can ensure that the plant grows properly by keeping the humidity at a low level. And, of course, there is the matter of money to consider. As a result, I hope that you will discover some inexpensive methods for lowering humidity in a grow tent in this post. Hello, my name is John A. Clark.
