r/microgrowery – Seeking clever ways to battle high humidity in MA.
First time grower, like this sub, and has been a follower for a long time. My setup will be the first thing I’ll discuss: Yaheetech 24 is a spacecraft “Tent with a 24″ by 48” footprint MEIZHI 300W Led Grow Light Full Spectrum is the lighting source. Ventilation: Intake fans: x2 120mm USB computer fans (for cooling). Vivosun 6 Inch 440 CFM Inline Fan with Speed Controller and 6 inch Stainless Steel Exhaust “Filter with Carbon Ducting Combo with 8 feet of length. Plant: 1 white widow feminized in a 5 gallon planter filled with FoxFarm FX14053 12-Quart Ocean Forest Organic Potting Soil (FX14053 12-Quart Ocean Forest Organic Potting Soil).
Fox Farms Tiger Bloom should be used every other watering, as instructed.
My main concerns are lower temperatures and more humidity, which are both on the rise.
When the lights are turned out, the temperature can drop to the low 60s and the humidity can reach the mid-50s.
- At this point, there is lots of air movement (I highly recommend the carbon filter exhaust setup I have).
- I recently purchased Damprid for the tent, but it appears to have had no influence on the humidity level (thinking about buying three more).
- In addition, the space heater scorched several fan leaves on one of the major colas, which was a bad sign.
- Any further suggestions would be welcome.
r/microgrowery – What are easy and cheap ways to control the humidity in a small tent?
Currently, the humidity is over 60% in my 40x40x120cm tent, which measures 40x120cm. It is highly dependent on the relative humidity outdoors. I’d want to be able to maintain the temperature below 50 degrees before my plants begin to flower, so that I have at least 1 – 2 months before they bloom. I have two little USB fans (the kind that you can put into the side of your laptop, for example) and a 75-watt bulb in the inside (using 30w) I’ve already opened most of the “valve” holes and kept the temperature not entirely closed at the top, but as I’ve previously stated, if the outside humidity is too high, I won’t be able to do anything.
I’ve considered experimenting with silica gel (that stuff you put in desiccators, for my fellow lab rats).
Is it possible to use a “carbon-filter+vent and fan system” in addition? Even if I still need to obtain it, perhaps that would be sufficient? Thank you for your responses, and have a nice day everyone:)

To make a comment, you must first log in or create an account. a second-grade education Thanks! Well, I’ll acquire one as soon as possible. level 1Can you tell me where you have the probe positioned? level 2On top of the dirt near the stemlevel 1At the base of the stem Dehumidifier. Edit. As far as I can tell, you’ve worked it out. My apologies for not posting comments initially. level 1I’m assuming you’re recirculating exhaust back into the space? Your humidity shouldn’t be that high if you’re exhausting it out the window unless you live in an area where humidity is that high on a regular basis.
- Investing in a dehumidifier is a costly and time-consuming endeavor; you’ll need something 20L or more.
- This will be a far less expensive solution.

I’d suggest that you use an air conditioning machine.
81 degrees Fahrenheit is a tad warm.
When the temperature is lowered, the amount of water that can be held in the air decreases as well.
To cut a long tale short, If you wish to reduce humidity, the air conditioner is the finest option.
a second-grade education There is no air conditioning in the room.
Do you have any recommendations for an excellent air conditioning unit?
What kind of window ac unit do you have?
If he is using HPS, you should aim for a pH of approximately 76.
Please educate yourself on a subject before spreading false information.
Please take note of those figures.
1st grade In the meanwhile, open a bottom vent to allow for some circulation to occur, turn up the air conditioning in your home, and if feasible, locate the tent’s bottom vent directly next to the AC intake vent.
Because it’s quite humid where I live, I’m used to dealing with this. level 2I’m ready to go, give it a go! Thank you for the information!
r/microgrowery – Humidity and dehumidifier options
We need to reduce the humidity in our grow environment, which like to be between 65 and 70 percent relative humidity. We’ve grown a lot of vegetables outside and in our little greenhouse, but this is the first time we’ve attempted to cultivate in a limited area, and it’s proving tough to maintain a consistent relative humidity. Prior to our become legal on October 17 and being able to start our first grow, I’m growing bell peppers as a test grow. When we purchased the house, it had a shed/storage space at the back of the attached garage, which had a door to it.
- In this room, which measures 8 by 10 ft (with a 9-foot ceiling), there is drywall on the walls and ceiling, as well as a concrete slab on the floor.
- I’m sure my neighbors would blame me for allowing their children access, and I’m sure they’d be upset with me for allowing their naughty children to trespass on my land and take my crop.
- We now have a 4×4 tent put up in the room, with four bell pepper plants in it for the purpose of testing the arrangement.
- For the past 4-5 weeks, we have seen temperatures ranging from 28C to 33C (82F to 92F).
- For the water, we are using a 55-gallon plastic barrel (with a cover) as a holding container.
- We’ve pierced a few of holes in the lid to let the water and power cables to go, so that the barrel doesn’t contribute much to the humidity in the room.
- We’re experiencing a problem with humidity right now.
Because our air conditioner is equipped with a “dehumidifier” function, even after a week of operation, we can keep the humidity level at 60 percent or even lower.
Our daily water use would be around 3-4 gallons, but the relative humidity would never go below 60%.
To make the space more comfortable, we must lower the humidity level.
The addition of a cover over the top of the soil will help to prevent evaporation (although I’m concerned about bugs and mildew developing in it).
– When it comes to purchasing a dehumidifier unit, we are confused if we should get a compressor unit or a desiccant one.
We need to come up with a solution because I don’t want to have buds rot on me and have to throw out entire crops.
Please provide any information you have on what works and what doesn’t work for efficiently decreasing humidity, as well as any other ideas you have for things we should try. Thank you so much for your assistance.
r/microgrowery – 2×2 High Humidity Advice
Hello there, Microbrewery! I’m 12 days into flowering in a 2x2x4 tent, which is my first grow. I have an AC Infinity T6 exhaust system with a Phresh carbon filter for my exhaust. I have negative pressure in the tent, with a single 6″ fan at the bottom of the tent delivering intake air. There’s also a little 6″ Hurricane clip-on fan positioned towards the top of the tent, which is blowing directly on the plant (not too hard). Despite the fact that I believe all of this is working, I am having difficulty dealing with the extreme humidity.
- The humidity in my tent remains in the upper 50s and lower to mid 60s as a result of this.
- I’ve looked into dehumidifiers and found that there is a vast variety of prices ranging from $30 to $200 or more.
- As a result, it appears that I will need to get a larger one that will help to reduce the humidity in the area where I am storing my tent.
- Is it possible that I’m on the correct track?
- I’m not opposed to spending money if it’s necessary, but I don’t want to go crazy on this 2×2 project.
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
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.
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 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.
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.
Other solutions include installing carbon scrubbers on the exhaust to eliminate any scents that may be present. 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.
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.
How To Increase Humidity In Grow Tent? Easy With 5 Tips!
Are you a gardener who enjoys your work? A garden tent is a terrific alternative if you want to be able to plant all year round without interruption. Grow tents are beneficial to gardeners because they allow them to manage the growth environment. These tents are composed of stretchy fabrics and have a bright lining on the inside to keep you visible in low light. It contributes to the retention of heat within the tent. Unfortunately, keeping the proper humidity levels within the grow tent is not a straightforward task to accomplish.
In my grow tent, I couldn’t figure out how to raise the humidity level!
Plants might suffer from reduced growth and development as a result of low humidity.
At different periods of a plant’s life, however, the amount of humidity it requires might vary significantly.
Otherwise, you risk losing your plants to the environment. The good news is that you can easily enhance humidity in grow tents by employing a few easy techniques that require little effort.
Why Is Humidity Important?
Humidity may be defined as the amount of water vapor present in the air in a specific location at any given time. In order to grow tents, we must first determine the relative humidity. It informs you of the percentage of water that is present in the surrounding air as well as the maximum amount of water that may be present at a certain temperature. A hygrometer may be used to determine the humidity level. It would be great if you kept in mind that plants may thrive at a variety of relative humidity levels; nonetheless, the temperature within the grow tent will have an impact on how well they develop.
What Happens When Humidity Is Low?
Water is essential for plants, as we all know, but what about relative humidity? When the temperature is high and the amount of water available is limited, dry air is produced. The plants are under extreme stress as they attempt to absorb more moisture in order to counteract the drying impact of the roots. Lower humidity levels can cause the roots to absorb more water, and if there are nutrients in the water, this surplus water can be detrimental to the plant’s health and growth. Low humidity can also increase the likelihood of a plant becoming afflicted with mildew or being infested by other insects.
Why Is High Humidity Important?
I was apprehensive about excessive humidity at first, and I was even concerned that it would hurt my plants. However, via trial and error, I have discovered that a high degree of humidity is really beneficial, particularly during the developing period. Because of this, the plants are able to absorb as much water as they need to survive. However, plants also absorb nutrients and water via the leaves and stems of the plants they consume water via. When there is a high level of humidity, plants have a better chance of receiving adequate water and growing properly.
What Are the Suitable Humidity Levels?
Natural humidity levels always fluctuate, therefore it is advisable to adjust the humidity levels in a grow tent in accordance with the various stages of a plant’s life cycle. For further information, please see the video below.
- Seedlings and young saplings demand a higher level of humidity. Ideal percentages should be between 70% and 75% of the total population. This is the period of time during which the plant’s root system is developing. It is important to maintain high humidity levels in order for saplings to establish robust root systems. Flowering plants need relative humidity levels between 40 and 50 percent to thrive. It provides them with an atmosphere that is favourable to their growth. Mildew and mold development can also prevented by maintaining slightly lower humidity levels. Humidity levels between 50 and 70 percent are ideal for plants that have already established themselves in the ground. Despite the fact that their roots have already established, they continue to suck in moisture through their leaves in order to grow more quickly. If possible, keep the humidity levels between 45 and 50% while you’re harvesting your crops. As a result, the fruit and vegetables will not get brittle or dry.
Although it is important to understand that relative humidity affects humidity levels, it would be preferable if you kept this in mind. So, before raising or reducing humidity levels, spend some time learning about how humidity behaves and affects plant development.
How to Increase Humidity in Grow Tent?
There are a variety of approaches that you may use to deal with the humidity issue. It will be determined by your financial situation and the amount of effort you are prepared to put in. Modest gardeners can get by with a few small stages, while more expert gardeners and pricey plants may need to take a few more significant measures. I’ve outlined a few possible courses of action from which you might chose based on your own circumstances.
1. No Cost and DIY Changes
- Mixing mature plants with young ones is one of the simplest things you can do in your garden. Larger plants respire more deeply, which raises the humidity levels in the growth environment. In any case, avoid overcrowding the tent, since this will make it difficult for tiny plants to acquire enough light and nutrients. Remove a Couple of Lights- It’s a simple matter of logic. Increases in temperature are accompanied by a decrease in humidity. Fluorescent lights generate heat, which may be used to dry a tent. Remove a few lights from the tent, but make sure there is still enough light in the tent. Fan Speed- For plants to thrive, free airflow and appropriate ventilation are essential for healthy growth. The fans that you employ must be adjusted at a reasonable speed to be effective. If the pace is too high, it might cause the plants to dry out and also prevent vapor from settling on the leaves of the plants. The low speed will cause the humidity levels to rise. Towels and trays- This is a low-cost and simple approach for increasing humidity. A damp towel should be hung near the air intake. Placing trays of water near the plants or near the passive air holes will help to keep them hydrated. Wet sponges are also an excellent alternative. It is possible to position them near a plant and watch the water slowly evaporate
- Spray Bottle- Spray bottles are commonly found in the gardens of most people. Use it to spray water on the tent’s walls twice a day, seven days a week. As a result, the water lingers on the surface for a longer period of time, providing the plants a better opportunity to absorb it.
2. More Expensive Changes
If none of the measures outlined above are successful for you, it is time to consider some alternative possibilities.
The grow tent or space may be rather large, in which case these DIY techniques will be ineffective. You will have to spend some money, but believe me when I say that the results will be well worth your while.
- Install an air conditioning unit- If you currently have an air conditioning unit in your grow tent, but it is not adequate, it is time to either replace it or add another unit. Before purchasing a new air conditioning unit, carefully analyze your needs depending on the weather, tent size, and other factors. Soil on the Floor- If your tent takes up a significant amount of space, it is likely that you will have some soil on the floor. You have the option of replacing this soil with one that has superior water retention. Alternatively, you may scatter it about the plants and observe the humidity levels rise
- Construct or purchase a Propagator setup. Seedlings and young shoots are well protected when grown in a propagator, and the increased humidity aids in the growth of the plants. You will require the following items in order to construct your own set-up:
Allow the water to run into the humidifier through a pipe and see how it generates a cool mist in the tent as it does so.
- Humidifier- If you don’t already have one, you should consider investing some money on a high-quality humidifier. It may be able to resolve all of your humidity issues. Maintain a working percentage of 50 to 65 percent. Get a humidifier that has an automatic control feature to make things even better. Keep an eye on the humidity levels, since too much might cause difficulties.
When we talk about boosting humidity, the first thing that comes to mind is the use of a humidifier to accomplish this. It has the ability to boost the moisture content of any growing environment by releasing water vapor into the air. Nonetheless, humidifiers are essential to a plant’s existence, especially when the plant is kept in a tent. Humidifiers may increase relative humidity in a limited space, making the environment more favorable for plants. You can achieve the appropriate quantities of phosphorus depending on the plants and their growth stage.
- The area to be covered by the grow tent, as well as its size, are critical considerations. Choose a humidifier that has the capability of covering the entire space. It also depends on the rate at which it humidifies and how long it may be left running. Look for a company that provides extensive and consistent coverage. The Water Tank’s Capacity- Every humidifier comes with a water tank of varying sizes. It would be better if you gave it some serious thought before proceeding. If it is too little, you will have to replenish it on a regular basis. When it is too large, finding a suitable location for it might be difficult. It is important to check if the humidifier has many settings available since you may require different mist settings at various times of the day. Safety features are quite important for any electrical item, and this is especially true for a humidifier. Some have an automatic shut-off feature that kicks in as soon as a specified humidity level is achieved
- Others have a manual shut-off feature.
Can High Humidity Be Bad?
Having too much of a good thing may be detrimental, just as it is with everything in life. Even though high humidity is beneficial to plant growth, excessive humidity can do more harm than good if it becomes too prevalent. Extremely high humidity can result in a variety of difficulties, including
- Molds are allowed to develop, and the plants’ ability to transpire effectively is hindered. It promotes the growth of bacteria and other undesirable organisms. The capacity of roots to absorb water diminishes, and they become more passive as a result. Reduce carbon dioxide intake, which is necessary for photosynthesis, by clogging the stomata of plants.
After reading this article, you should realize that increased levels of humidity in a grow tent are beneficial to the optimal growth of plants. It’s important to remember that humidity is affected by a variety of different elements, including ventilation, light, temperature, and water. As a result, it is a good idea to keep track of all parameters, not only humidity. When you have finished reading the information I have provided here, you will have a better understanding of how you may enhance the humidity levels within a tent.
The cost-effectiveness of some of the solutions allows you to experiment with them early in order to figure out what works and what doesn’t.
Please do not hesitate to contact us if you have any questions or concerns.
We are certain that you will soon be able to observe your plants developing more quickly and in a healthy manner if you follow the advice provided here.
How To Lower Humidity In Grow Tent Or Grow Room
Keeping the relative humidity under control may be a challenge for indoor growers, and it can occasionally lead to difficulties. Experienced indoor growers understand that maintaining the proper humidity level in your grow tent is important to the success of your indoor plant growing endeavors. If the humidity level in your grow tent is too high, learn how to control the humidity level in your grow tent. High humidity levels can cause delayed growth, bud rot, fungal development, mildew, and mold to appear on the leaves of plants.
The humidity level in your grow tent should not be more than 70%.
Don’t be concerned; the very items that you’ll find in your grow tent may be the solution to keeping the humidity level in your grow tent at an optimum level. This article will discuss some basic ways for decreasing the humidity in a grow room without spending a lot of money in the process.
Understanding Relative Humidity
Let’s start with a little scientific lesson: humidity is defined as the amount of water vapor present in the air. At the same time, relative humidity may be defined as the relationship between present absolute humidity and the greatest potential absolute humidity. In layman’s words, relative humidity is the point at which the air becomes entirely saturated with water vapor and is no longer able to contain it any longer. Keep in mind that there will always be some amount of water vapor in the air.
Heat in a grow tent encourages water to travel more quickly through the air, resulting in a greater level of humidity in the environment.
Why High Humidity Is Bad And Causes Problems
So you’ve been informed that high humidity is essential for the strong development and health of your growing plants. Do you believe it? Humidity is extremely beneficial to plants. However, although this is true, overly high humidity levels in your grow tent might cause more harm than good to your plants. If you do not want your grow tent to do any of the following:
- Bacteria and molds thrive in this environment, which is ideal for them. Allowing your floral plants to succumb to bud rot or botrytis Increase the hazard posed by pests and pathogens
- Prevent your plants’ transpiration, or exchange of air, from occurring
- Encourage the growth of undesirable microbiological organisms
- Clog the stomata, reducing carbon dioxide intake, which is necessary for optimal photosynthesis to occur
- Make the roots inactive by reducing their capacity to absorb water on their own own
- Reduce the rate at which your plants absorb nutrients
- Reduce the amount of produce produced by your plants.
Then it’s time to figure out how to keep the humidity levels in a grow tent as low as possible for the duration of the grow.
Importance Of Low Humidity In A Grow Tent
When it comes to humidity levels, it is important to remember that a low humidity environment in your grow tent may do wonders for your plant. Homogeneous conditions and moisture build-up in a grow tent might cause your flower or buds to get moldy and die. Other problems associated with excessive humidity include:
- It is possible for white mold to irritate your leaves, preventing them from taking in water and oxygen, as well as light. Rust fungus: This fungus causes rust patches on the leaves of plants. Root rot occurs when the soil is excessively damp for an extended period of time.
Grow Tent Size
It is important to consider the size of your grow tent from the beginning since you must guarantee that all regions are covered by a reasonably low level of humidity in all places. For example, a44 grow tent requires 40 percent of the total energy, but a55 grow tent requires at least 65 percent. My 4×4 grow tent can accommodate a home dehumidifier, thus a small dehumidifier that can absorb 8 to 10 ounces of moisture each day will enough for a 2×2 grow tent.
What’s the best grow room temperature?
Although temperature changes, it is necessary to provide you with an understanding of how to regulate humidity. Make certain that you have a thermometer and a hygrometer on hand. Clones or seedlings prefer temperatures between 74 and 78 degrees Fahrenheit, although vegging plants may live at temperatures as low as 70 degrees Fahrenheit. In order to flower, flowering plants require greater temperatures of 88-75 degrees Fahrenheit than plants ready to harvest, which can tolerate temperatures of 65-74 degrees Fahrenheit.
What’s The Best humidity level?
Plants flourish in a variety of humidity levels throughout their lives, at all stages of development. Seedlings or clones require 70 percent to 75 percent humidity because plants need time to grow their root systems, which forces them to rely on their leaves to absorb water until their root systems are fully developed. Having enough of moisture in the air is essential for feeding your newborn plants. It is for this reason that indoor producers employ propagation trays or humidity domes to accumulate moisture.
Flowering plants require 40 percent to 50 percent humidity in order to provide a pleasant environment for their leaves to breathe.
When it comes to indoor horticulture, humidity is a critical factor to consider.
In order to be successful as gardeners, we must be aware of the humidity levels that are appropriate for different phases of plant growth and different plant species.
Humidity, in conjunction with temperature and light, can assist producers in raising healthy, vigorous plants that produce abundantly and efficiently.
Here How To Lower Humidity In Grow Tent
According to everything I’ve said thus far about the importance of high humidity, it can also be harmful if the levels get excessively high. Here are some tried-and-true and simple methods that indoor gardeners have used to help minimize humidity in their grow tents:
1. Avoid overwatering your plants
Protecting your plants from overwatering is one of the most straightforward methods of lowering humidity levels. Overwatering results in more water being produced, which may result in a rise in humidity in your grow tent that is beyond the recommended amount. In the same way, damp soil will leave excess water in propagation trays, which will enhance the humidity levels in the same way.
2. Use a Dehumidifier Inside your Grow Tent
I’m confident that you’re familiar with our old acquaintance, the dehumidifier. When the air in your grow tent becomes too humid, a dehumidifier can assist to extract the excess moisture from the air, therefore decreasing the humidity levels. You will most likely have to spend more money on this because a grow tent will normally require the use of an industrial dehumidifier. We must make significant investments in resources in order to assure overall plant development and yields. If your site is already humid, I recommend that you use a high-quality dehumidifier that is connected to a drainage system.
- If possible, your dehumidifier should be capable of eliminating at least the same amount of moisture from the air as your plants absorb on a regular basis.
- Learn more about how to select the most appropriate dehumidifier for your grow tent.
- Some dehumidifiers include an automated shut-off option that activates when the water reservoir is full.
- Therefore, the entrance and outflow of a humidifier are both located within your grow tent, which might result in the space becoming overheated.
3. Check your plant density
Naturally occurring carbon dioxide is released by plants, which causes the temperature in your grow tent to rise. As a result, moisture accumulates and the relative humidity rises. Increasing the amount of plants in your grow tent might cause the air in the tent to get displaced, preventing other regions from receiving fresh air and carbon dioxide. Continue reading to learn how to determine the optimal amount of plants that should be accommodated in your grow tent. Keep in mind that if your grow tent does not have adequate dehumidification and ventilation, the water vapor transpired by your plants will be retained.
4. Remove stagnant water
Remember how I said you didn’t have to spend a lot of money attempting to lower the humidity levels in a grow tent? Well, I was right. Here’s one of the most cost-effective strategies we can employ! As indoor producers, it is our job to ensure that our grow tents have adequate drainage so that stagnant water does not pool on the ground and contribute to excessive humidity. Water that has become stagnant has the disadvantage of reducing molecular oxygen concentrations to the point where bacteria may develop and flourish.
One of our most common mistakes is to leave water reservoirs exposed or to allow stagnant water to develop puddles on the floor, which causes moisture to be released into the air. There’s nothing worse than having your grow tent turn into a breeding ground for bugs and pathogens.
5. Improve ventilation by adding more fans
In order to enhance ventilation in your grow tent, I propose adding extra exhaust fans or increasing the speed at which the fans rotate. Increasing the quantity of airflow in the grow tent is the most practical technique to assist raise the amount of oxygen available. Utilize an atmospheric controller with a humidity setting, if feasible, to automatically adjust the fan speed to achieve the desired level of humidity. Another option is to use a duct fan or open a window to force moisture out of the grow tent, which is a straightforward solution.
- This form of ventilation will lower humidity levels since the positive pressure within the grow tent provides enough air movement to provide a mild breeze across the whole tent.
- I should caution you against depending solely on oscillating wall fans to provide proper air circulation; these fans might fail to do so since they can only lessen the temperature on the canopy.
- I now recommend that you purchase floor fans to draw air through the canopy and guarantee that carbon dioxide is distributed evenly.
- Using a hygrometer controller to power fans is a dependable automation method, according to my experience.
6. Create air holes
Making large or narrow openings in your grow tent might help you manage the flow of air in your growing environment. To reduce humidity, expand the openings in the ceiling to guarantee that more air enters than escapes from the ceiling. Take care not to allow any unnecessary light into the room.
7. Purchase an air conditioner
It is well-known that the primary function of an air conditioner is to chill the air and reduce humidity levels in the surrounding area. The gadget extracts heat from the air by compressing it and using gas to do so. In addition to generating condensation, this procedure eliminates moisture from the air in a highly efficient manner. Large air conditioning equipment, on the other hand, tend to operate on short cycles or for short periods of time, creating an unpredictable climate for your plants.
In addition, there is the issue of frequent variations, which can cause the temperature in your grow tent to skyrocket to dangerous levels.
This may also be used in conjunction with a fan to assist maintain a cool climate in your grow tent by minimizing the amount of water vapor produced.
As a result, you must choose a suitably sized air conditioner for your grow tent that is capable of drawing sufficient water from the surrounding air. It is important to remember to clean the filters since clogged filters hinder proper airflow, which causes the humidity to rise.
8. Insulate and seal your grow tent
When it comes to controlling humidity, one of the most important things to consider is making sure your grow tent is properly insulated and sealed. I construct a substantial barrier between the outside environment and my grow tent by insulating it with foam insulation. I am less concerned about my plants being threatened by external sources as a result of this.
9. Use grow equipment wisely
I’d like to caution you that grow equipment, such as grow lights, might cause the temperature in your grow tent to rise significantly. Consider purchasing a grow lamp that does not produce a lot of heat. If the temperature in your grow tent is too high, switch off the lights to let the temperature to decrease. Allowing your lights to go to sleep can also help you save money on your power bills.
10. Make use of absorbent soil
As indoor gardeners, we need to be aware with the many types of soil that are acceptable for our plants’ needs. Utilizing soil that has the ability to retain water underneath a grow tent is essential for lowering humidity levels. I recommend that you use sandy soil to reduce evaporation rates and the amount of water that is exposed to the sun. Alternatively, perlite is an option, although sandy soil is less expensive—a nice reminder to replace the soil on a regular basis. I’ve also noticed that utilizing lime or baking soda offers the same benefits as using sandy soil when it comes to growing vegetables.
Always choose surfaces that are absorbent.
11. Consider defoliating your plants
Another option that is more cost-effective is presented below. Plants with large leaves, such as leafy plants or plants with large leaves, might cause the humidity levels in your grow tent to rise. I normally try to reduce the amount of humidity in the air by removing some leaves from the trees.
To sum it up…
Indoor producers must keep track of both humidity levels and temperature readings, as well as the relationship between the two. We will be able to better understand how environmental conditions influence the development and survival of our plants in this manner. Generally speaking, plants will have a difficult time transpiring if both humidity levels and temperature levels are high. As a result, growth and development are slowed significantly. Furthermore, ventilation is one of the most important factors affecting humidity levels in a grow tent.
- To maintain high-quality growth and increased yields, it is necessary to keep humidity levels under control.
- Remember, first and foremost, you must comprehend the contextual conditions.
- Alternatively, if this is not practicable, there are low-cost alternatives such as the use of exhaust fans, a hygrometer controller, monitoring ventilation, or managing plant density.
- If you use appropriate gardening tools and maintain adequate ventilation while keeping relative humidity levels low for your plants, they will appreciate you.

How to Ventilate Your Grow Space
You must have adequate ventilation in order for your plants to flourish. By giving your plants with fresh air from outside your grow tent, you are supplying them with CO2, which is necessary for their photosynthesis. Meanwhile, removing the air inside will help to keep the temperature and moisture buildup under control, avoiding mold and mildew from growing on your plants’ leaves and so hindering their ability to thrive. The extra benefit of refreshing the air within is that it helps to eliminate unpleasant smells.
Essential Grow Tent Parts
Assuming you have previously chosen or purchased your grow tent, this tutorial is equally useful if you are working in a grow room. This is a list of the three most important components that you’ll need to put together while building a ventilation system:
Inline Duct Fan (Active Exhaust Fan)
An inline duct fan, also known as an extractor fan, is a device that is used to exhaust hot and humid air from within a growing chamber or tent. Even little variations in temperature and humidity may have a significant impact on your chances of generating a fruitful harvest. Furthermore, unregulated heat and humidity cause poor growth circumstances, resulting in your plants being unable to absorb water or simply failing to make it through the day. The use of an inline duct fan in your grow room is essential for controlling the climate in your growing environment.
Using an active exhaust fan to draw in cooler air can assist you in maintaining a comfortable inside temperature level.
In ventilation systems with passive intake, inline duct fans also serve as a vacuum, drawing in new CO2 from the outside air and bringing it into the system.
Inline duct fans are attached to your grow room using ducting that is clamped or glued in place. The ducting serves as a channel to divert stagnant air away from your grow space. They are typically constructed of aluminum, although they may also be multilayered to provide additional protection against rips. Its size and bends have an impact on the performance of your inline duct fan, but we’ll get into that later.
A carbon filter will be required in order to prevent scents from traveling to your garage or closet. This device, which is also known as a carbon scrubber, removes the smell of plants from the air, capturing the odor and neutralizing it. Carbon filters are a must-have for growers that have to cope with very strong odors. They are also used to trap pollen and spores, which helps to keep the air clean for farmers who suffer from allergies or respiratory problems such as asthma.
Typical Grow Tent Setups
There are several configurations for these components that may be used to create airflow into your grow environment. As a standard configuration, the fan and the filter are placed inside, which makes it easy to control while also dampening the noise from the fan. If air is being drawn out of your grow room, one or both of these components can be placed in any sequence within the ventilation chain. It is possible to customize your ventilation system in at least four different ways in order to meet your requirements.
The fan and/or filter can be placed outside of the grow tent in this situation.
Because heat rises to the top of the building, venting that hot air at that point will improve the efficiency of the ventilation process. Your carbon filter will also operate better if it is installed at the greatest possible elevation.
What Size Inline Fan do I Need?
There are many different sizes of grow areas, and each one requires a particular amount of airflow to be properly ventilated. It is critical for maximum plant growth that stale air within your grow room is exchanged with fresh air from the outside of your grow area. CFM (cubic feet per minute) is the unit of measurement for this number. To determine the quantity of airflow required for your grow room, first calculate the volume in cubic feet of the space. Most grow tent specifications are offered to you in inches; thus, you must convert the size of your space from inches to feet.
This will match the capacity of your grow room, and the needed airflow will be equal to this value in cubic feet per minute, or CFM, as well.
When the dimensions are added together, the result is 72 ft 3 in length.
Keep this amount handy since you’ll need to adjust it to account for the ducting, carbon filter, and any other accessories you decide to install.
Factoring in Accessories
In order to boost your base CFM, you must multiply it by the efficiency percentages of your accessories. Adding components to your grow room, including as ducting and carbon filters, may limit fan performance, which will have an impact on the fan size you require. When it comes to ducting, the quantity and sharpness of its bends play a role in determining the resistance to airflow. As a result, airflow decreases the longer it needs go, making a straighter ducting path more effective. The greater the sharpness of the curve, the greater the severity of the efficiency drop; a 30° bend reduces airflow by 20%, while a 90° bend reduces airflow by 60%!
- If you are utilizing LED grow lights, you must also take into consideration their heat production, which can raise your necessary CFM by as much as 50%.
- Because the efficiency of accessories on the market might vary substantially, you can utilize approximated efficiency percentages based on the type of component you are using.
- This amount is multiplied by the efficiency % of each component to arrive at the final result.
- Adding in the heat output of your grow lamp (about 50%) gives us a needed CFM of 249 cubic feet per minute.
- The following is a breakdown of this calculation: Multiplying your base CFM (72) by the percentages of ducting (20 percent), carbon filter (60 percent), silencer (20 percent), and grow light heat (50 percent) of your choosing will provide about the 249 CFM you require.
- This will let the fan to operate at lower speeds while remaining quieter, as well as providing additional area for future expand space system growth.
Look for inline duct fans that are powered by direct current (DC) fan motors, which are the quietest as compared to alternating current (AC) fan motors. PWM-controlled EC motors are also acceptable in terms of acoustic performance.
How to Manage Grow Space Noise
There is no question that you will hear some noise when employing a high-powered fan to air your grow environment. You wouldn’t want to spend an extended period of time in an area with excessive noise pollution or catch the attention of your neighbors. Fortunately, you can plan your component selection with noise reduction in mind, and you can take further steps to make your grow area as as quiet as possible. Making the decision to choose a fan with speed controls and a CFM rating that is 25 percent more than your minimal need will allow you to run the fan at lower speeds without compromising performance.
If you want to further muffle the sound of your active exhaust fan, you may attach a silencer to it, which will lessen the sound of the intake fan.
