How to Increase Relative Humidity in a Grow Tent
Documentation Download Documentation Download Documentation Grow tents are incredible instruments that allow you to have complete control over the environment in which a plant grows. They are great for growing plants in your house, but they can be tough to handle due of the high humidity levels they produce. Many plants, particularly seedlings and cuttings, require extremely high levels of humidity to thrive. Relative humidity is a measurement of the quantity of water vapor in the air, and there are numerous simple ways to raise the level of relative humidity.
- Read More About ItRead More About It Using a grow tent, you may exert complete control over the environment in which a plant is grown. It is possible to use them to grow plants in your house, although controlling the humidity level might be challenging. Numerous plants, particularly seedlings and cuttings, require a high degree of humidity in order to flourish. When it comes to relative humidity, it is a measurement of the quantity of water in the air, and there are several simple ways to raise it. Making sure that the relative humidity level is maintained can help to guarantee that your plants remain healthy and live longer.
- Sponges dry out more quickly than bowls of water, resulting in an increase in the amount of moisture in the air. It’s also possible to put them closer to your plants and lightbulbs in order to distribute moisture more rapidly
- Another alternative is to place sponges inside of bowls or trays that have been filled with water. It will hasten the evaporation of water
- When used in tiny, vertically oriented tents with shelves, sponges perform nicely. Despite the fact that these tents don’t have a lot of room, you can generally squeeze the sponges in between the plants on the shelves.
- 2 Place water bowls inside the tent for a more gradual increase in temperature. Fill up bowls or trays in the sink, then spread them around the grow tent to keep it from being too hot. A large intake fan located near the ground on one side of the tent is common. Position one of the containers near the air vent, and then place more containers near adjacent air vents to complete the installation. In order for the water to evaporate, the humidity level must rise.
- Water bowls are convenient since you can refill them as needed and remove them when they are no longer needed. They are more effective than towels at increasing the humidity of the tent on a constant basis. Bowls should be used in large tents with enough of floor area and ventilation. When used in conjunction with an internal ventilation fan located at ground level, they are the most effective.
- s3 Temporarily raising the humidity level can be accomplished by hanging damp towels. Soak the towels in water for a few minutes before spreading them out about the grow tent. Place them near any air vents that are located around the edges of your tent. As air is drawn inside the tent, it will come into contact with the towels. The moisture draining off of the towels raises the relative humidity level in the room.
- Maintain a safe distance between the towels and grow lights and other heat sources to prevent them from burning. Towels are not intended to be a long-term solution, but they can be used to temporarily increase the humidity level. Towels may be used in any type of tent, as long as you have a place to hang them from the ceiling. The best option is to stay in tall tents with an inside fan that blows air in from near the ceiling to keep you cool. It’s also possible to hang them near air vents that are close to the ground.
- 1 Use a humidifier to automatically regulate the humidity level in the air. You may use a regular household humidifier to keep the air in your grow tent moist. Many grow tents are also equipped with ceiling supports from which you may hang a humidifier in order to conserve floor space. Instead of having to constantly monitor the water supply and temperature in your house, consider purchasing a humidifier with automatic settings. The humidifier will discharge water into the air in order to maintain a constant humidity level.
- Use of a conventional household humidifier will necessitate daily refilling with new water if you want to go that route. Check it at the same time every day, such as every morning, to ensure that it continues to function properly
- Make certain that you are using a humidifier rather than a dehumidifier. In order to reduce the relative humidity, a dehumidifier must be used to remove moisture from the air.
- 2 Decrease the speed of the extractor fan to prevent the air from drying out as soon. If there is a ventilation fan near the tent’s ceiling, it will suck stale air out of the tent. It also removes a significant amount of humidity from the tent, so keep the fan running at a moderate level. If you have any additional fans that you use to circulate fresh air between plants, you should also turn them down to a low level as well. If necessary, you might even turn off the ventilation system for a short period of time, such as for around one hour every day, in order to elevate the humidity level more quickly.
- It is critical to maintain air circulation throughout the tent in order to maintain a uniform temperature throughout
- Thus, do not turn off the fans permanently. For bigger tents equipped with a ventilation fan with variable speed settings, this method is effective. Some bigger tents also include wall-mounted fans that may be turned down to reduce the heat.
- 3 Lowering the temperature is a simple method of increasing humidity. Utilize the fact that your plants can tolerate a lower temperature to simply raise the humidity levels in your home or office. If your tent has a temperature control option, make adjustments to it. Alternately, you may install an air conditioner or a water chiller inside the tent to keep it cool. To keep the temperature lower than normal, you might also add fans or turn off the lights.
- When the temperature is lowered, colder air descends to the bottom of the tent, causing condensation. Warm, moist air will ascend to the surface of the atmosphere, increasing the degree of humidity. Make sure your tent is equipped with a thermometer so that you can keep an eye on the temperature. In addition, maintain the tent well-insulated and well-sealed so that the temperature remains consistent. The temperature settings on higher-end hydroponic tents are frequently programmable. In a smaller tent with plenty of storage, you might not have enough space for an air conditioner or a water cooler.
- The colder air descends to the bottom of the tent as a result of lowering the temperature. Humid air will ascend to the surface, increasing the relative humidity. In order to keep an eye on the temperature, make sure your tent contains a thermometer. Aside from that, make sure the tent is well insulated and shut so that the temperature remains consistent. The temperature settings on higher-end hydroponic tents are frequently adjustable. If you have a smaller tent with a lot of storage, you may not have enough place for an air conditioner or a water cooler.
- If your grow tent has many light sources, removing some of the bulbs is a fairly simple technique to raise the relative humidity in the growing environment. Some smaller tents, on the other hand, will not allow you to accomplish this. This method is most effective with young plants. Seedlings are less sensitive to light than adult plants, and this is especially true for young plants. They require more humidity than they do more light, which is why most tents are equipped with replaceable bulb lights. Some low-cost tents, particularly tall and thin versions, may not be equipped with various light sources.
- 1 If you have additional space in the tent, you may put larger plants in there as well. Even if you’re growing seedlings, you might want to include some fully-grown plants in your container. If you’re cultivating little herb plants, you may include some taller veggies or blooming plants to break up the monotony of your garden. Maintain a sufficient distance between the plants so that they do not overwhelm one another. Make certain that each one receives a enough amount of light and water.
- Large plants require more watering than smaller plants, but they also transpire more moisture than smaller ones. The moisture that is released into the atmosphere contributes to an increase in relative humidity. As they grow older, mature plants are able to take in more water through their roots, reducing the amount of water they must extract from the air, as they do with younger plants. Large tents with plenty of floor area are the only ones that will work for this. In some cases, if your tent is tall or has an adjustable height, you may be able to accommodate larger plants in it. Hydroponic tents with shelves are frequently insufficiently spacious
- 2 If your plants are spread out, group them together near together. Place them directly next to one another so that the leaves do not come into contact. They will still require adequate space to develop. Over time, each plant will release water that the other plants may utilize, causing the overall humidity level to increase.
- 2 If your plants are spread out, try to group them together. Do not put the leaves too close together or they may suffocate one another. Still, they will require sufficient room to develop. Over time, each plant will release water that the others may utilize, causing the level of humidity to rise.
- 3 Mist plants with a spray bottle if your plants require a modest boost in the morning sun. Lightly mist both sides of the leaves with water to prevent them from becoming brown. The additional water will cause the humidity level to rise, and your plants will benefit from the fresh water that will be available immediately. When used on seedlings and cuttings, it is most effective since they are unable to absorb water through their roots. If you want to keep the humidity level high for the long term, you’ll have to check back each morning and spritz all of the plants again if the level has dropped.
- Spray plants with a spray bottle if they require a little extra help. Water should be applied to both sides of the leaves to keep them from drying out. Watering your plants more frequently will increase humidity levels while also providing them with new water on a more frequent basis. When used on seedlings and cuttings, it is most effective since the roots will not be able to absorb water. Keeping the humidity level high over the long term will need checking back each morning and misting all of the plants again if the level has dropped.
- 4 If you are unable to elevate the humidity level to a satisfactory level, cover the plants with bell cloches. Cloches are domes that are used to assist manage the temperature and humidity levels in the environment around certain plants. Each plant will require its own cloche, which you will need to purchase separately. Plants should be moved beneath the domes, and then the ventilation openings on each dome should be pulled open. Cloches, even when they are open, assist in retaining more moisture.
- Even something as basic as a plastic bag can be used to increase the amount of humidity in a room or space. For example, you may place them over seedlings. If your grow tent is correctly set up, you won’t need to use any cloches at all. They are most useful in emergency situations or when you need to swiftly elevate the humidity level. Some plants, such as carrots, radishes, peas, and parsley, do very well when grown beneath cloches

- If you don’t already have one, invest in a digital hygrometer that you can hang or place inside your grow tent. It keeps track of the relative humidity
- In general, seedlings need a greater relative humidity than do mature plants. Start with a 65 percent to 70 percent concentration and then reduce it until it is 40 percent to 50 percent when the plants begin to blossom. When the humidity level is too low, the plants begin to dry out, which is harmful. For example, you could observe that the leaves are becoming dark and curled
- In addition, high humidity levels can be harmful to plants, so keep an eye out for rot or powdery mildew.
For those who don’t already have one, you should invest in one that can either be hung or stood within your grow tent to measure relative humidity. When the humidity level is high, the device monitors this. As a rule, seedlings require a greater relative humidity than mature plants. Start with 65 percent to 70 percent, then gradually reduce the percentage until it is 40 percent to 50 percent when the plants begin to blossom. It is possible for plants to get dehydrated if the humidity level is too low.
In addition, high humidity levels can be harmful to plants, so keep an eye out for rot and powdery mildew.
- Grow tents have a large number of electrical components that are susceptible to harm from water. Make a point of keeping towels, sponges, and any other moist things away from the lighting and heating components at all times.

Do you have a marijuana plant growing in your home? Then you’ll have a significant edge. When you’re inside, you have total control over the surroundings. You have the ability to provide your plants with the optimal circumstances for maximum development and productivity. For plants, the optimal degree of humidity depends on the stage of development they are in. Of course, if the relative humidity within your grow tent falls outside of these optimal parameters, cannabis will continue to thrive.
Furthermore, if the humidity is really low, they will suffer greatly.
Naturally, this means that there may come a moment when you will need to raise the humidity in your grow tent to get optimal results.
How To Increase Humidity In A Grow Tent
However, before we get into the best methods for increasing relative humidity in a grow tent, we want to point out that it is possible you will not need to raise it at all.
When weed plants are seedlings, they require the maximum levels of humidity possible. There is a fair probability that you are attempting to raise humidity levels because you have seedlings that require a high degree of moisture in the air to survive.
Raising Humidity For Marijuana Seedlings
If your plants are seedlings, we recommend that you do not even bother trying to raise the humidity level in your environment. 70 percent is a challenging quantity to achieve, especially in a large grow tent with a lot of light. Furthermore, it has the potential to cause problems with some of the equipment that may be present in the grow tent. Instead, it is much simpler to construct a smaller, more restricted environment around the seedlings and to raise the humidity solely within this smaller environment, while keeping the humidity in the remainder of the grow area unaffected by the changes.
It is recommended that you use an apropagator tray with a humidity dome, but you may easily rig something together on your own.
Simply misting the inside of the dome with a spray bottle on a frequent basis will be sufficient to maintain humidity levels.
If they aren’t already too enormous, they will be in the near future.
Increasing Grow Tent Humidity: Best Methods
There are a variety of methods for increasing the humidity inside your growing environment. We’ll go through all of the greatest strategies with you below so that you can pick which one is the most effective for your situation.
Use A Humidifier
If you need to boost the humidity level in your grow tent or grow room on a constant basis, nothing works better than using a humidifier. It is the most straightforward approach, and you can obtain reasonably decent ones for a reasonable price. There are a few characteristics that you should look for in a humidifier. It should be equipped with a built-in humidistat. You may program it to turn off automatically when the humidity reaches a specified level and turn on automatically when the humidity decreases below that level.
You’ll also want one with a large enough tank capacity so that you don’t have to be filling it up all the time.
If you are unable to locate a nice humidifier that satisfies all of your needs, here is an excellent one available on Amazon that will suffice for a little grow in an area of 4 by 4 feet or less.
Using a humidifier that sprays mist into the air is a wonderful idea, but only if you use filtered water rather than tap water, which may be harmful (this is actually a good idea with any humidifier to be honest).
Tap water will leave mineral deposits on the leaves of your plants, as well as on the walls and floor of your tent, if you use it to water them.
A less complicated method is to simply add water to your grow tent as needed. This can be accomplished by placing some bowls, buckets, or other water-holding containers on the floor. Alternatively, you may put a damp towel (or several) inside the tent to keep the bugs away. It goes without saying that this approach is less precise than utilizing a humidifier when it comes to obtaining and maintaining the desired humidity level. You’ll have to keep an eye on it and make adjustments until it’s exactly where you want it.
Humidity is increased in two ways when there is insufficient ventilation. For starters, the circulation of air within the tent helps to dry up any moisture. Second, moisture is carried away by the air that is vented out of the tent by the extraction fan. Of course, there are some situations in which it is not possible to reduce the volume of air that is vented out of the tent. For example, you could be coping with heat-related problems. You should always make sure that you have enough fan power for the size of your grow tent.
All of the top grow tent fans offer a variety of speeds.
Because colder air does not require as much moisture content to get saturated as warmer air, lowering the temperature in your grow tent will also raise the relative humidity in your grow tent. Obviously, you don’t want to resort to reducing the temperature if doing so would result in the temperature dropping below the optimal range for your plants and their present growth stage. For cannabis, this implies that you should avoid going below the following temperatures throughout each stage of growth:
- Climate: 73° F (23° C) for seedlings
- 70° F (20°C) for vegging
- 65° F (18° C) for flowering
Effects Of Low Humidity On Cannabis Plants
Plants do not just absorb water via their roots; they also transpire water. They also obtain water by the extraction of moisture from the air by means of their leaves. If there is no moisture in the air, plants will be unable to obtain water in this manner and will be forced to rely only on their roots for water. When it comes to young plants in particular, this can be an issue. Clones do not yet have a well-developed root system, therefore they must obtain the majority of their water from the surrounding environment.
- If the relative humidity is too low, clones may not be able to root at all or only partially.
- During vegging, plants receive more water from their roots, but they still rely on the water provided by their leaves to survive.
- It can also induce nutrient burn, which can result in yellowing leaves and, in the worst case scenario, the death of your plants.
- Why does this happen?
- Understandably, it is critical to ensure that your weed plants are growing in the proper humidity conditions.
Extremely dry air can cause a variety of major health concerns. However, you must be careful not to raise the humidity levels too. When it comes to growing plants, too much humidity can be detrimental, especially during the blossoming period.
Effects Of High Humidity On Marijuana Plants
bud mold or rot is the most serious hazard connected with excessive humidity levels. Find out what mold on cannabis looks like in this article. Obviously, this only occurs during the flowering stage, when the buds are developing. You should keep humidity levels as low as possible during flowering since it is the primary cause of bud rot. In addition to low humidity, excellent ventilation is required to ensure that moisture does not build on the buds’ surfaces. Using the proper size smart pots might assist to prevent this problem.
The fact that it may grow on plants of any age implies that they are more vulnerable during the early developmental stages of their development, when humidity is higher.
An oscillating fan is ideal for this application.
Raising Grow Tent Humidity: Final Thoughts
Low humidity, particularly in the early stages of growth, can seriously impair the development of your plants. But proceed with caution. High humidity has the potential to make things worse. If your humidity level is dangerously low, invest in a humidifier and boost it; but, if it is dangerously low, you could be better off doing nothing. Being a bit low won’t have much of an impact, while being too high would. As is often the case, keeping things simple is the best approach. Learn how to keep things as easy as possible when cultivating marijuana in your home.
How to Increase Humidity in a Grow Tent?
Plants’ growth can be severely hampered by low humidity, especially in the early stages of development. However, use caution in this case. When it comes to humidity, more is not always better. You should use a humidifier to improve the humidity levels if they are dangerously low. If they are near, though, you may be better off doing nothing at all.” Although being a bit low won’t make much of a difference, being too high will do so. Always remember that keeping things simple is always the best course of action!
How to increase humidity in a grow tent?
If you want to enhance the humidity in your grow tent, you may start combining plants of different ages together. Another option is to add water directly inside the grow tent. You may also reduce the brightness of the lights and the speed of the fan to assist in providing more humid air to your plants. Alternatively, you could simply get a humidifier.
Ways To Increase Your Grow Tent’s Humidity
Keep in mind that the humidity level in your grow tent may be adjusted and raised to meet the specific demands of your plants if necessary. Plants will not develop as rapidly if the humidity within the grow tent is too low for extended periods of time.
As a result, the plants will be physically and mentally shorter in both size and longevity. There are various safe methods for increasing the humidity in these grow tents and controlling the growth environment surrounding your plants. Here are a few examples.
Start Mixing The Plants
You may mix your plants according to their maturity without having to put in a lot of effort in order to control the humidity within the grow tent. The higher the humidity levels surrounding the younger and smaller plants are when bigger plants are mixed with them, the more likely it is that they will try to catch up with the older and more established plants.
Add Water To Your Grow Tent
If you want to control the humidity within the grow tent, you may mix your plants according to their age without putting in a lot of extra effort. If you group together larger plants next to smaller plants, you may anticipate the humidity levels surrounding the smaller plants to rise, providing a healthy and growing environment in which they will desire to catch up to the mature plants.
You may mix your plants according to their maturity without having to put in a lot of extra effort in order to control the humidity within the grow tent. The higher the humidity levels surrounding the younger and smaller plants are when bigger plants are mixed with them, the more likely it is that they will try to catch up to the older and more mature plants.
Reduce Lights and Fan Speed
Because an increased presence of heat is known in most situations to absorb the air, causing it to become dry, you may want to lower the amount of lights in your grow tent to avoid overheating the atmosphere. As crucial as light is for the growth of these plants, it is equally critical to maintain an optimal balance between heat and humidity during their development. The frequent blowing of your fan might also have a detrimental influence on the humidity in your grow tent. Due to the fast speed of the wind, the water in the air will evaporate quickly, drying up your plants and reducing the total output.
When it comes to moving air around without drying it out, a medium speed is frequently the best option.
Too much humidity and its effects
If you discover that you are really skilled at producing humidity for your grow tent, you should avoid overdoing it. If you attempt to make all of these modifications at the same time, you may end up with an excessive amount of humidity in your grow tent. You can have a detrimental impact on the roots of some plants, preventing them from receiving the right amount of water required for optimal growth. Mold, fungus, and bacteria can thrive in your grow tent if there is an excessive amount of humidity in the environment.
Reasonable humidity level
If you discover that you are really skilled at producing humidity for your grow tent, you should avoid exceeding your capabilities. Use of all of these distinct modifications at the same time may result in excessive humidity in your grow tent if you attempt to do so. You can have a detrimental impact on the roots of some plants, preventing them from receiving the required amount of water necessary for healthy growth.
Mold, fungi, and bacteria can form in your grow tent if there is an excessive amount of humidity in the area. Depending on the plant, this might be fatal or cause the plant to spread to other plants in the vicinity.
Moving Forward With Humidity
Once you have set up your grow tent and brought in your seedlings and plants, it is critical to understand what sort of humidity level you will want in the grow tent so that you can begin creating that level as soon as possible after starting the grow tent. What works for you may be very different from what works for someone else, depending on your local environment and the placement of your grow tent. Take into consideration the local elements and climate, and then begin working to alter the humidity to meet your specific demands for your plants and provide the most potential output.
Cost Of Increasing Grow Tent Humidity
The humidity level required in the growing environment should be determined before you begin bringing in seedlings and plants. This will allow you to start creating that level as soon as possible after you start your grow tent and bring in the seedlings and plants. What works for you may not work for someone else, and this is dependent on your local environment and the position of your grow tent. Examine the local elements and the surrounding environment before setting out to alter the humidity to meet your specific demands for your plants while producing the highest potential harvest.
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.
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.

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. Keep the following considerations in mind while shopping for a humidifier.
- As soon as we hear the words “increase humidity,” the first thing that springs to mind is “hygrostat.” Water vapor may be released into the air, increasing the moisture content of any grow area. When growing plants under a tent, humidifiers are very important since they keep the soil moist. Humidifiers can improve the environment for plants in limited spaces by increasing relative humidity. You can attain the appropriate levels based on the plants and their growth stage. Keep the following considerations in mind when purchasing a humidifier.
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.

How to Increase Humidity in Your Grow Tent (10 Easy Ways)
The most recent update was made on January 18, 2022. It is not difficult to develop a cannabis plant from seed to harvest. With order to develop that perfect sticky icky that is coated in crystals and that generates a gorgeous, potent high, you’ll need to make sure that you take care of specific elements in order to maintain your plants growing at their healthiest and happiest possible. Even while temperature, nutrition, light cycles, and other important factors are easily recalled, there is one more thing to keep in mind: relative humidity.
However, understanding the humidity requirements of your plants is only a tiny part of the struggle.
Increasing the humidity in your grow tent is important for keeping your plants happy and ensuring that they achieve their full potential.
Understanding Relative Humidity
On the surface, humidity appears to be a rather straightforward idea. What percentage of moisture is present in the air? However, there are a variety of methods for measuring humidity. If we’re talking about horticulture, we’re going to be paying close attention to relative humidity. In other words, what exactly is relative humidity? The quantity of moisture in the air in relation to the temperature of the surrounding environment is referred to as relative humidity. According to how hot or cold it is, varying degrees of moisture can be retained by the atmosphere.
The percentage of the total volume of water that the air can hold at any given moment is stated as a percentage of the total amount of water that the air can hold at any given time, up to 100 percent.
Condensation, dew, fog, and other types of moisture are the outcome of this process.
Similarly, if the temperature rises but the total amount of moisture in the air remains constant, the relative humidity percentage will decrease because the air is now capable of retaining a greater volume of moisture.
Factors That Affect Relative Humidity
All of the activities taking on in your grow tent might have an impact on the relative humidity levels within. Each of these elements has an impact on it on its own, but they also interact with one another to alter it.
As previously stated, altering the temperature of an environment will likewise alter the relative humidity of that environment. In a grow tent, fans and lighting help to regulate the temperature, which is important for crop growth. The heat produced by the lights might cause the relative humidity in the grow chamber to decrease. However, not all lights generate the same amount of heat. Compared to metal halide or high-pressure sodium lights, modern LED lights generate far less heat. Therefore, the relative humidity of your grow tent will be less affected by their presence.
The amount of ventilation and airflow in your grow tent will have a significant impact on the relative humidity within it. If the air is exchanged too fast, it might dry up and cause the surrounding environment’s humidity to drop significantly. However, if there is insufficient ventilation, the air will stagnate and the humidity will grow.
Given that humidity is a measure of the amount of moisture in the air, it stands to reason that having more water in the environment would result in a greater degree of moisture. The greater the size of your water sources, as well as the amount of water present in your grow tent, the higher the relative humidity levels you will experience in your grow tent.
How Much Humidity Do Cannabis Plants Need?
Following our discussion on relative humidity, as well as some of the elements that might influence the humidity levels in your grow tent, let’s talk about how much humidity your cannabis plants actually require. Most of the water that your plants take in will be through their roots, but they will also absorb a little amount of the moisture in the air through their leaves. This frees up their roots, allowing them to better absorb the essential nutrients they require to develop and thrive. However, the humidity requirements of your plants will fluctuate as they progress through their life cycle.
When your plants are just getting started and are still rather little, their root systems are not yet matured enough to handle large amounts of water. The result is that they will be absorbing significantly more water via their leaves, and the humidity levels must be high enough for them to adequately hydrate. Temperatures should be in the range of 65 to 80 degrees Celsius for these young plants.
Once your plants have progressed past their first development stage and are ready to begin vegetating, you’ll need to lower the humidity in your grow tent to ensure that they thrive. Humidity levels between 55 percent and 70 percent should be sufficient at this point. Keep in mind that each strain has its own set of preferences, so these values are only a starting point for your research.
Now that your plants have made it through the vegetative stage and are ready to blossom, they’ll be requesting even lower humidity levels as they prepare to bloom. As soon as they begin to blossom, you should reduce the humidity to someplace in the 40 percent to 50 percent range.
The humidity in their habitat should be reduced gradually as they progress through the flowering stage until the relative humidity is between 30 and 40 percent by the time they are ready to be harvested.

The 10 Ways How to Raise the Humidity in Grow Tents
Having established what elements influence humidity and the estimated amount of humidity your plants will require at any stage of their development, let’s move on to specific methods of increasing humidity within your grow tent.
1. Add More Plants
During a process known as transpiration, plants are able to “breathe.” To put it another way, they’re excreting water vapor via their leaves after receiving it through their root systems. As a result of this transpiration, the relative humidity increases. Increasing the number of plants in your grow tent will increase transpiration, which will in turn increase the humidity in your grow tent. These plants, on the other hand, do not have to be cannabis. Any form of huge plant will aid in the growth of humidity in the environment.
2. Reduce Ventilation
Don’t turn off your ventilator fans totally; instead, turn them down to a low level. Your plants want fresh air and circulation, but an excessive amount of airflow will dry up the air and dehydrate your plants. Reduce the airflow and allow the humidity to rise as a result of this.
3. How to Increase Humidity in Your Grow Tent
It may seem little, but hanging some damp towels near the air entrance of your grow tent is an excellent method to give moisture to the air in your growing environment. During the passage of air over and through the wet towels, it will take up and cling onto the water contained inside them, raising the humidity level in your grow tent.
4. How to Increase Humidity in Your Grow Tent
Because plants in the early stage of their lifecycle require the greatest amount of humidity to grow, you’ll need a means to keep them moist and content. Fortunately, propagators make this quite simple. It’s similar to a little plastic dome that keeps all of the moisture contained within it. You’ll see water droplets accumulating on the lid as a result of condensation; this is evidence that your seedlings/clones are receiving adequate humidity.
5. Add a Humidifier
What do we do when we need to increase the humidity in our homes? We add a humidifier to the mix. In other words, what works for ourselves will work for our plants as well. Adding a humidifier to your grow tent is an excellent method to rapidly enhance the amount of humidity in the environment. With a humidifier that has many various settings to select from, you can even alter the humidity level to fit the changing demands of your plants as they progress through their development cycles.
6. Reduce the Heat
Because hot air can store more total water than cool air, a hotter tent will have lower relative humidity than a cooler tent with the same quantity of moisture in the air. You may enhance the relative humidity by removing some of the heat from the air. Try removing one or more of your lights from your grow tent to see how much of an impact it has on the humidity of your grow. If you’re using several lights, try removing one or more of them to see how much of an impact it has on the humidity of your grow.
7. Spray the Walls of Your Tent
Every day, spray the walls of your grow tent with a basic spray bottle to keep the bugs away.
When these water droplets evaporate, they will contribute to an increase in the relative humidity of the tent. It is possible to increase the humidity even more by spraying more water or applying it many times during the day.
8. Use a Swamp Cooler
Swamp coolers cool the air by adding moisture to it while simultaneously lowering the temperature. As a result of the fall in temperature, there is more water in the air, as well as a greater relative humidity as a result.
9. Add Water Sources
In addition to cooling the air, swamp coolers also add moisture to it. A greater relative humidity is produced as a result of the reduction in temperature, resulting in more water in the air.
10. Cool the Tent Down
Adding an air conditioner to your grow tent will result in a fall in temperature, which will be countered by an increase in relative humidity. This is a straightforward method of increasing humidity without the use of water. However, if you make the climate too chilly for the plants, they may not appreciate it as much.
Your cannabis plants’ humidity requirements will change as they progress through the many stages of growth that they will experience. If you want to create the greatest blooms and the largest harvests possible, you’ll need to make adjustments to the humidity levels in your grow tent to match these shifting requirements. The changing requirements of your plants during their life cycle have been highlighted, from the high humidity requirements of seedlings and clones to the significantly reduced requirements of blooming plants.
The final point to mention is that we discussed ten distinct ways that you may raise the humidity in your grow tent right now.

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
February 2, 2022 is the most recent revision. An entirely plausible notion is to use a grow tent to provide shelter for an expanding cannabis plant. The process of setting up a complete room so that it is ideal for plants might be time-consuming and not really worth it for a tiny grow operation. However, due to the fact that a grow tent is a lot more contained environment than an open space, there may be a few problems that arise. How to maintain humidity in a grow tent is the most pressing of these concerns.
This might result in growth problems or molds destroying the plants if left unchecked. In order to properly acclimate a cannabis grow tent, there are several aspects to keep in mind. Continue reading to learn how to reduce the humidity in a grow tent, boost it, and regulate it all at the same time!
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.
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. Credit for the featured image goes to JRByron of Pixabay.
