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 wet floor in a room, or any other container of water can be used as a water storage container. In case it’s near an oscillating fan, the airflow over the surface will turn more water into vapor, and bammm! 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. 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.

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.

Dehumidifier Outside or Inside Grow Tent?

When it comes to growing plants, humidity is critical. However, excessive humidity leads to condensation, which in turn leads to mold and other problems in the home. As a result, employing humidifiers is the most effective method of dealing with high humidity. However, there is a heated discussion regarding where dehumidifiers should be placed. Dehumidifiers should be placed either outdoors or within the grow tent. The solution is straightforward. Dehumidifiers may be placed both outdoors and within a grow tent to keep the environment moist.

Now, without further ado, let us get down to business with the specifics-

Deciding where to place the dehumidifier

The location of your dehumidifier is determined by two considerations. Take into consideration these two elements and then determine whether or not it is possible to install a dehumidifier in a grow tent.

Factor 1: Grow Tent Size

When it comes to deciding where to put a dehumidifier, this is the most important consideration. It’s possible that your grow tent doesn’t have enough room. It is not necessary to remove a plant in order to make room for a dehumidifier in this circumstance. Place the dehumidifier outside the grow tent and you’re done. As a result, the location of your dehumidifier will vary depending on the size of your tent.

Factor 2: Grow Tent Air Movement

How much air is going through your grow tent at any one time? The most powerful dehumidifier has a capacity of 200 m3/h of air. It is necessary to install your dehumidifier outside if your extractors remove more air than 200 m3/h. Consider the following scenario: you place your dehumidifier in a room with a 300 m3/h air flow. Your dehumidifier will now begin to function properly. However, by the time it was intended to dehumidify the entire tent air, new air had replaced the old air in the system.

Condensation will begin to form in the grow chamber shortly.

Placing Dehumidifier Outside Grow Tent

If, after evaluating your circumstances, you determine that you should install your dehumidifier outside of your grow tent, we are here to assist you. The technique of installing a carbon filter outside a grow tent is really quite similar to that of doing so inside. However, there are some distinctions. So, let’s walk through the procedure step by step: Because you want to position your dehumidifier outside your grow tent, we will assume that one dehumidifier will be sufficient for your growing environment.

As a result, there are two options for positioning the dehumidifier outside the grow tent. A full room dehumidifier is being used in one room, while a ducted dehumidifier in the other is being used in the grow room.

Option 1: Whole Room Dehumidifier

In this example, we’ll assume that your grow tent is located within a room. In addition, the air coming into your grow tent is being drawn from the interior of the room. The strategy is straightforward at this point. It is necessary to use a dehumidifier to bring the relative humidity (RH) of the entire room down. If the relative humidity (RH) of your room air declines, your grow tent will automatically get dry air.

Option 2: Ducted Dehumidifier

This procedure is a little time-consuming, but it is more efficient and cost-effective. In addition to your dehumidifier, you’ll need a few more items to complete this task. Your shopping list is as follows:

  1. The following tools and materials are required: duct flanging kit, box cutter, duct tape, insulating duct, cardboard box

Let’s go through these stages one by one:

  1. Find a cardboard box large enough to accommodate your dehumidifier as a first step. After then, secure it in close proximity to a power source. In order to power up your dehumidifier, you don’t want to run any additional wire. After that, cut a hole in your box that corresponds to the size of the dehumidifier’s intake. The whole near ground side of the box should be cut
  2. Set up your dehumidifier within the box in such a manner that the dehumidifier inlet does not come into contact with any of the other components. Then seal up the hole using duct tape. Another hole should be made in the opposite end of the box, and an insulating duct should be run through it. The insulating duct will be used to connect the box to the intake fan of your grow tent. Secure all of the connections and turn on your dehumidifier
  3. Now you’re done.

This manner, you’ll be able to directly supply dry air to your grow tent without any additional equipment.

Placing Dehumidifier Inside Grow Tent

Many growers wonder if they may use a dehumidifier in their grow space. In fact, as we previously stated, the answer is “yes.” Adding a dehumidifier to your grow area is a good idea. However, you must be aware of the optimal collection of concerns. What is the best location for a dehumidifier in a grow tent? The answer to this issue has been a source of consternation for producers all over the world for some time. You’ll discover folks who are willing to share their dehumidifier configuration.

We’re here to discuss the most important considerations you should keep in mind while utilizing a dehumidifier in your grow room.

Know Your Dehumidifier Capacity

Plants excrete nearly all of the water that they consume. As a result, you require a dehumidifier that is capable of dealing with all of the humidity. Let’s use an example to demonstrate what I mean. Consider the following scenario: you consume 30 gallons of water each day, and about 8 gallons of that water ends up down the drain. So you have around 22 gallons of water floating around in the air. Let’s get down to business and do the math. One gallon is equivalent to eight pints. As a result, you require a 176-pint dehumidifier to effectively dehumidify your grow area.

Perfect Placement

The installation of a dehumidifier in a grow room can either make things easier for you or make things more difficult for you. As long as the dehumidifier has adequate airflow from the fans, it can be placed above the lighting fixtures. If you have more than one dehumidifier, make sure they are all placed at an equal distance apart. This is significant since it allows for the creation of separate zones for each of the dehumidifiers. When humidity levels rise in one zone, a dehumidifier can address the situation in its own zone.

This situation would have been far worse if you had only one dehumidifier to cover the entire region at the time.

Do not overlook the importance of paying attention to the finer points, such as orienting the filter side of your dehumidifiers toward the center of your room’s circulation path. Your dehumidifier for grow room will only provide top-notch service if it is properly placed in the room.

FAQ

Is it okay to use a dehumidifier in a grow tent for drying purposes? Answer:Yes, it is possible. Start by putting your plants in the drying room and turning on your dehumidifiers. If you follow all of the stages, you should be able to complete the drying process in 7-10 days. Is it okay for me to water my plants with dehumidifier water? Answer:Yes, it is possible. Water from a dehumidifier has no pollutants or metals. Simply ensure that the air entering the system is appropriately filtered. Is it true that dehumidifiers make a room seem cold?

It draws in dry and warm air from outside the grow area.

Because it lowers the relative humidity, air may be quickly cooled down.

Bottom Line

According to cutting-edge research, the dehumidifier should be adjusted in accordance with the plant’s life cycle. Dehumidifiers are an excellent tool for ensuring that your plants develop to their full potential. We trust that by now all of your misunderstanding regarding where to put the dehumidifier has been resolved. Put forth your time and effort to create the finest possible habitat for your growing plants. Wishing you the best of luck!

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. As a result, marijuana plants require significantly less moisture at the conclusion of their growing cycle.

Different Growth Stages Need Different Humidity

In terms of plant preferences, cannabis is a rather forgiving one. Growing conditions for it are rather diverse. However, if you provide it with the ideal conditions, it will reward you with harvests that are far larger and of significantly better quality. It is also worth noting that the plant is not particular about its environment, even under ideal conditions. It prefers a temperature of around 70 degrees Fahrenheit and an average humidity level. In other words, there’s nothing out of the ordinary!

Overall, marijuana plants require far less moisture as they near the conclusion of their development cycle.

  • 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.

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 internal complication 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.

Where to place dehumidifier in grow tent

Dehumidifiers are excellent machines for ensuring that the humidity levels in a place are maintained at a comfortable level. Excessive quantities of wetness in the environment are detrimental to everyone’s health. Whether it is the relative humidity in your living room or the relative humidity in your grow tent, humidity must be controlled. High levels of relative humidity have their own set of detrimental consequences on the interior of a house. Mold and mildew development, musty odor, wood decay, and other issues are all possible.

It is critical to have a dehumidifier installed inside the grow tent.

Installing a dehumidifier in the grow tent or grow room will allow the air to be evenly circulated and devoid of moisture, which will benefit the plants.

Let us learn more about the answers to the questions about dehumidifier placement in the grow room, as well as why growers welcome the idea of placing a dehumidifier in the grow home, and how the cultivation benefits when the air quality in the grow room or tent is improved when you place your dehumidifier inside or near it, among other things.

Why do you need a dehumidifier in grow tent?

If you are still perplexed as to why you would want to put a dehumidifier inside a grow tent, here is what you need know. As a result of the watering of plants, a change in the amount of humidity in the surrounding environment occurs. There is a change in the humidity level in the grow rooms when you water plants, no matter how restricted the available space is in the grow rooms. Another component that contributes to the increase in humidity in the grow room is the natural process of sweating, as well as the air that is being drawn into your grow tent from the outside environment.

Where should you put a dehumidifier in grow tent?

During the installation process, pay close attention to the dehumidifier positioning in order to get the best results. In order to utilize the dehumidifier to its maximum efficiency or potential, the location in which it is installed must be considered. The location of the dehumidifier within the grow tent will have an impact on the results of the dehumidification process that takes place within the tent. There are a number of factors that will influence where your dehumidifier should be installed.

  • When deciding where to put a dehumidifier, it has been suggested that you experiment with the airflow from the fans to see if that works better for you.
  • Furthermore, this is a solution for fitting even a strong dehumidifier into grow rooms with restricted space.
  • Make sure that the dehumidifiers are appropriately positioned across the room.
  • It should be noted that, if the humidity level in a certain zone increases, the unit will only have the capability or obligation to manage or concentrate on that particular zone.
  • Many farmers, however, believe that this is not a cost-effective answer for them, and as a result, they are opposed to this viewpoint.

The air filter in the dehumidifier is the next important feature to keep in mind throughout the installation process. “It is advised that you position the device within the room in such a manner that the filter side is pointing towards the center of the grow room,” says the author.

What happens when you place a dehumidifier inside the grow tent?

It is possible to install a dehumidifier within the grow chamber. The gadget will monitor the amount of humidity in the air and maintain control over the temperature and moisture content of the air in the surrounding area. The capacity, efficiency, and dimensions of the dehumidifier, as well as other criteria associated to it, will determine how the dehumidifier should be set up and installed within a grow room, among other things.

What happens when you place dehumidifier outside the grow tent?

It is fairly uncommon to locate a dehumidifier outside of a grow room. It may be the most effective method of ensuring that dehumidification is completed effectively. Dehumidifiers installed outside grow rooms are identical to carbon filters installed outside grow tents in terms of installation. This technique, on the other hand, comes with two possibilities, and you may choose whatever one is most beneficial to the health of your plants. One type of dehumidifier is a whole-room dehumidifier, while the other type is a ducted dehumidifier.

How long should a dehumidifier run in a grow tent?

For best results under a grow tent, it is advised that farmers run their dehumidifiers for 10 to 12 hours (or more) every day. This is dependent on a variety of factors, including the unit capacity of the dehumidifier, the quantity of plants present, the relative humidity (RH) in the air, and other factors. Furthermore, whether one is dealing with a full room dehumidifier, a ducted or suspended dehumidifier, the number of pints of water that is removed every day, and so on are all aspects that are related to this process.

How to choose the size of dehumidifier for grow tent?

The type and size of dehumidifier you choose for your grow room is determined by the number of pints of water that will be removed by the device. In this way, it is directly tied to the amount of water that must be extracted from the environment. Because plants evaporate 97 percent of the water they consume, the quantity of moisture they return to the grow room will be the same as the amount of water they take in. If you use 20 gallons of water per day for your plants, you’ll need a unit that can remove 20 gallons of water per day from the system.

BTU is an abbreviation for British Thermal Units.

If the unit that you have is capable of producing an excessive amount of BTUs, you will be creating an unhealthy atmosphere for your plants.

Because of this, the effectiveness of dehumidifiers, as well as the size you require, will be mostly determined by the criteria listed above.

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.

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.

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. You can keep your grow tent’s drainage system in good working order so that any surplus water may be channeled away.

Plants naturally emit carbon dioxide, which actually increases the amount of moisture and humidity in the air. In other words, if your plant’s density is more than usual, there will be more moisture and vapors, which will result in increased humidity. What should I do? Make an effort to keep the spacing between your plants to a bare minimum. Make sure it isn’t too thick. Overwatering your plants is never a good idea. Overwatering does not imply that your plant will develop more quickly. It might, on the contrary, bring you misery.

  • Because too much water surrounds the roots, they are unable to absorb oxygen and nutrients necessary for the plants to grow and thrive.
  • Another approach for decreasing humidity in a grow tent is to incorporate air holes within the structure.
  • Because the air does not become trapped inside the grow tent, there is no condensation inside the grow tent as a result.
  • 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.

Final Thought

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.

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.

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

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.

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.
