How To Keep Humidity Down In Grow Tent

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:

Increased Transpiration

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.

Overwatering

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.

Harvesting/Drying: 30-40%

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.

Germination/Cloning	Vegetation	Flowering	Harvesting/Drying
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.

1. 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
2. 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)
3. 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.

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.

Passive Ways

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: –

1. 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?

1. Water that is stagnant yet does not puddle on the ground
2. 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 increase the humidity in your grow tent. This, however, alters during the blossoming process. 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

The terms relative humidity and temperature are synonymous. Temperatures that are higher than optimal are OK as long as the humidity is lower than ideal. In the same way, vice versa. This means that you may, in essence, compensate for greater than optimal humidity by maintaining lower than ideal temperatures. That being said, this is really just a smart option if you’re having trouble getting the humidity levels under control. It is far preferable to really reduce the humidity while maintaining the temperature where it should be at all times.

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.

1. Having a high humidity level will assist the plants in thriving as all portions of the plant develop and thrive at the same time.
2. However, in order to maintain the fast rate of development, they will require additional water from the surrounding environment.
3. Humidity levels should be between 40% and 50% throughout the flowering stage.
4. 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.

1. As a result, the roots are less able to absorb water.
2. When this occurs, the plants begin to suffer from mineral shortages as a result.
3. Plants grow healthier, stronger, and more leafy when the humidity in their grow environment is at the proper level.
4. 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.
• 2.
• 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.

5.

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°
Vegetative	40-70%*	71-82 F°
Flowering	40-50%	68-79 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.).

Controlling Humidity

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.

1. Choosing to jump a few pages ahead and getting it done correctly the first time with a business dehumidifier is another.
2. No matter how hard you try, humidity levels will not miraculously decrease on their own.
3. if you put in the effort to make them great.
4. 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.

How to Control Humidity in Your Grow Tent (4 Easy Ways) – Easy Guide

The most recent revision was made on February 2, 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.

How to Control Humidity in a Grow Tent

Source: cannabispromoter, courtesy of Pixabay 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.

2. Ventilation

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.

The most important thing to understand about cannabis plants is that they prefer stable temperatures. 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.

4. Dehumidifiers

In most small to medium-sized grows, air conditioning, air circulation, and a good exhaust system should be sufficient to keep the humidity in a growtent within tolerable ranges. However, this is not always the case, particularly when anything goes wrong. Individually owned humidifiers will not suffice in this situation. They become overflowing much too soon, and they are just not designed to manage the large volumes of water that your cannabis plants produce. The possibility of purchasing an industrial-scale dehumidifier is likewise not a viable option for most farmers, mostly because to the high cost.

This, on the other hand, is not a really bright concept.

Most portable dehumidifiers, depending on the size of the tent, will perform well as long as they are utilized in conjunction with other instruments.

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.
