How To Make A Tent Feel Less Humid

How to Prevent Tent Condensation

Tent condensation is something that happens to everyone. Campers and backpackers who use tents will always experience condensation, although it is typically only a minor inconvenience and not the end of the world in most cases. Even yet, there are many myths concerning tent condensation, including whether or not it is possible to purchase a tent that totally resists condensation. Unfortunately, it is difficult to ignore the rules of physics once they have been established. Despite the fact that condensation happens in all tents, both single- and double-wall tents, it is a natural phenomenon that occurs regardless of the fabric or materials used to construct the tent.

What causes tent condensation?

When humid air comes into contact with a cooler surface, such as the inner walls or roof of your tent, condensation occurs. If you take a hot shower and the steam causes your bathroom mirror to become wet, you are experiencing the same phenomenon. When steam, which is just water vapor in a gaseous state, comes into contact with a mirror, it cools and condenses, forming liquid water droplets that coat the surface of the mirror with moisture.

How to reduce tent condensation

When you are in a tent, the quantity of condensation you feel is a function of the humidity in the air around you as well as the amount of wet air you release from your lungs when you breathe out. To limit the quantity of condensation that collects in your tent throughout the night, you should do the following:

  1. Expel humid air and wet exhalations from your breath by rolling back the rain fly or leaving the vestibule door open in your tent. During the night, take any damp clothing or shoes out of your tent. Dry them outside or place them inside a stuff sack to lessen the amount of humidity in the air at night. Cooking and boiling water should be done outside your tent to prevent raising the humidity level inside. Camping near streams, lakes, and ponds, as well as in damp or marshy locations where the humidity is strong, is not recommended. Yes, it’s convenient to set up camp near a water source, but doing so increases the likelihood of tent condensation occurring. A low place in the terrain where chilly air might collect at night is not a good location to pitch up your tent. If the walls and fly of your tent are warmer, you will experience less condensation.

What is the best tent for avoiding condensation?

There isn’t a single best tent that works for all climates, seasons, and environments. The most crucial component in reducing tent condensation is always going to be making the right choice of camping spot. However, different designs of tents have their own set of advantages and disadvantages that should be taken into consideration. Tents with a single wall: Tough tarp tents, tarp tents with mesh sides, and tarps with mesh sides are normally relatively easy to ventilate, however they can be quite drafty in cooler temperatures.

However, if you only camp during the warmer months, they may be an excellent option for you.

Double-wall tents have less airflow than single-wall tents, but they may be used in a broader range of temperatures since they retain more body heat during the night. Despite the fact that they do not completely prevent internal condensation, they do help to keep it away from you and your gear. Any water vapor that accumulates within your tent, such as that produced by your breath, will travel through the mesh inner tent and pool on the inside of the rain fly instead of soaking into the ground.

What if it’s raining?

Because there is more humidity in the air when it rains, your chances of encountering tent condensation are higher if you are out camping. There are similarities to camping by a creek or pond, but it is far worse. Having a single-wall tent or shelter is a good idea, and you should always have a small camp towel or bandana with you so that you can use it to wipe away any condensation from the tent before it drops into your stuff. Ensure that the rain fly is extended as far away from the inner tent as possible if you’re using a double-wall tent.

This is especially important around the sides and corners of the tent, which are particularly vulnerable. It is recommended that if your fly attaches into the base of your inner tent, you stake it out independently to allow for better ventilation between the two levels of the tent.

How significant is moisture in your breath?

While sleeping at night, you exhale around one liter of moisture. Whether you’re conscious of it or not, it’s one of the reasons you wake up thirsty in the middle of the night or the morning. If there are two people in the tent, you will have to deal with two liters of tent condensation, and so on as the number of people in the tent increases. If you’ve ever tented in a tent in the winter, you’ll know that the inside of the rain fly is normally coated with frost in the morning, which is caused mostly by the breath of the campers.

What if your sleeping bag gets wet from tent condensation?

In order to repel water, most sleeping bags and blankets are made of a water-resistant external shell fabric or one that has a DWR coating applied. Alternatively, if your shell becomes wet or damp, it is preferable to dry it in the sun the next morning while you are eating breakfast or during a break throughout the day. It is usual and expected for backpackers to stop to dry wet gear, tent fly, and clothes on a regular basis, and it is a good idea to get into the habit of doing so as necessary.

What if your tent or tent fly is soaking wet in the morning?

If you’re not in a hurry, you may leave it to dry in the morning sun, but this will take some time and patience. If you have to leave right away, another alternative is to wipe down the rain fly with a clean camping towel, which will remove a considerable portion of the water from the situation. Afterwards, store the fly in an outside pack pocket or a separate plastic bag until later in the day, when you take a break from your hunting activities.

Can you set up a wet tent fly at night?

Although you may want to set up camp a bit early that evening so that your tent has a chance to dry out before you go inside it, this is quite possible. I’ve set up wet tents in the summer and they’ve dried in an hour or less, but your results may be different.

Cooking in your tent is not recommended. It is best not to bring damp clothes or equipment into the tent. Set up your tent as completely as possible. Clean the interior of the tent with a damp cloth.

Do tents need to be waterproofed?

Tents should be waterproofed anytime they begin to exhibit indications of wear and deterioration. This might indicate that water is leaking into the tent via the seams or that you have seen peeling on the interior of the tent.

Can you put a tent away wet?

Put it away damp and it will grow mould or mildew, the material will degrade, and it will at the very least make your tent smell unpleasant, so avoid doing so. Some of the contemporary tents are also rather large, so drying them out is a significant undertaking in and of itself.

How do you set up a tent for rain?

15 Points to Remember When Setting Up a Tent in the Rain First, put up a lightweight tarp to protect the area. This is, without a doubt, the most vital piece of advice. Purchase a tent with removable panels that can be zipped out. Choose a suitable location. Make sure you’re wearing proper footwear. The fly should be rolled inside the tent. Purchase or construct your own rain gear. Purchase a single-wall tent for your needs. Bring a bivvy that is waterproof.

Can you waterproof a tent from the inside?

Choose a dry day to apply the proofing materials outside or a dry inside location, such as a garage, where you can leave them to dry while you work on other projects. Start by putting together your tent – since you’ll be sealing the seams on the inside side of the tent and underside of the fly sheet, turning the fly sheet inside out will make it simpler to get at the seams.

How do you stop condensation in a bivvy?

Use a wrap, a skull cap, or an inner capsule to protect your head (where available) In order to decrease condensation, these bivvy attachments are designed to create an air hole between the inner and outer textiles, which is then sealed with tape.

Why does tent get wet inside?

What is the source of condensation in tents? Because of the presence of people, heaters, and a lack of ventilation, the air temperature in the tent might become warm and humid. During the condensation process, moisture condenses into liquid form when the heated air within the tent comes into contact with the comparatively chilly tent fabric.

Can you sleep in a tent with mold?

Yes, it is possible to sleep in a moldy tent; however, it is not a pleasant experience, and you should remove as much mold as possible before sleeping inside. While mold spores are not good for your health, if you clean up as much as you can and you have no other choice, a night or two shouldn’t be too bad to survive.

How long should you air out a tent?

Allowing your tent to dry and airing out the odors is recommended. Make certain that all of the forest debris has been removed from the tent and allow it to set for 2-3 days.

Many times, the stench will just dissipate with the passage of time. In the event that you have recently washed your tent, you may use this procedure to fully dry it. Wait one extra day once you’ve determined that it’s dry and ready to leave.

How do I stop condensation in my tent in winter?

In a single- or double-wall tent, here are a few camping strategies to help you reduce the amount of condensation that accumulates. Your Tent Should Be Ventilated. Cooking in your tent is not recommended. Don’t bring snow into your tent unless absolutely necessary. Don’t take a deep breath into your sleeping bag. Drying your sleeping bag in the early light is a good idea. Wet gear should be placed in a Stuff Sack.

Why do tents leak when touched?

When a tent’s canvas is touched during a rainstorm, the tent begins to leak. What causes this? When you place your finger on a wet canvas, surface tension will pull the water to your fingertip. When the humidity is high, whatever is left will still attract condensation more than the rest of the inner tent surface, causing it to seem to leak from that location.

Can you go camping in the rain?

Place a heavy-duty tarp below your tent to protect it from the elements. Tents can flood when camping in the rain, and this happens more commonly from below rather than from above. Putting a heavy-duty tarp under your tent can help avoid this from happening in the first place. Extra tarp should be folded under the tent so that you can’t see any of the tarp at all.

Why do tents get so hot?

Solar gain is responsible for all of the heat you experience inside the tent when it is exposed to direct sunshine. If you take that away, the internal temperature will be the same as the temperature of the surrounding air. If there are any trees in the vicinity, you could conceivably tie a tarp to many of their trunks, with the tarp centered over the tent.

Should I use a tarp under my tent?

A tarp or ground cloth should be placed beneath your tent, even if it isn’t absolutely essential. When applied properly, they protect your tent from punctures and help to limit mud and water seepage into the tent inside. Unfortunately, the majority of individuals use a tarp that is far too large, which leads to even more complications.

How do I keep my tent floor dry?

Instructions for Keeping the Tent Dry Under your tent, spread a ground cloth to protect the ground. Maintain a higher elevation for your tent than the surrounding region at all times. The use of a tarp inside the tent might assist to keep the flooring more dry if the tent’s floor has begun to leak. Make certain that you have a tent with a rain fly that provides adequate protection.

What happens if you put a tent away wet?

Before you put your tent away, make sure it’s completely dry. There is a good chance that your tent will be covered in mould or mildew when you next take it out of its bag if it is left wet in its bag after a rainstorm. This will necessitate a thorough cleaning of the tent, which may cause your camping trip to be postponed or cancelled altogether.

Will heating a room stop condensation?

Generally speaking, internal condensation concerns arise as a result of excessive humidity in the room or insufficient air circulation in the room. Heating (to keep surfaces above the dew point temperature) and ventilation are the most effective treatments for condensation (to expel the warm, moisture-laden air to the outside). Condensation is responsible for some of the wetness.

Let’s start with the level of humidity.

When temperatures are high, water condenses and becomes trapped in a gaseous state.

It’s for this reason that there’s dew on the ground first thing in the morning.

When warm air from the inside comes into touch with cold walls, it condenses to produce water on the surfaces of the walls, which is known as condensation. There are methods for reducing the amount of moisture in the air, even though it will never be totally eliminated.

Create Air Flow Inside the Tent

Did you know that each individual exhales around a liter of water each night as they sleep? Did you know that? This is one of the most common reasons for condensation to form inside a tent. Creating air flow can aid in the movement of some of the moisture outside the tent and into the atmosphere. The best method to accomplish this is if you have screened windows and the weather is mild enough to allow you to leave them open. Another fantastic option for producing a cross-breeze is to unzip or roll up the front entry, which will help to keep the air inside the tent from becoming too moist and humid.

There must be some form of ventilation in the tent, or else condensation will become an even worse problem.

Use a Double-Layer Tent

The primary advantage of single-layer tents is that they are more lightweight, which is particularly advantageous for camping. It will be worth your while to invest in a double-layer tent while going on a standard camping vacation, since you will almost certainly have the capacity to haul a lot more weight than you would if going on a hiking excursion. The two layers are made up of the breathable tent material and the waterproof rainfly that is placed on top of it. A double-wall tent will keep you drier, but it will also need more effort to put up because it must be anchored and secured in several places.

Knowing how to tie adjustable tension knots can come in helpful in this situation, as well.

Check Your Tent Before Camping

Prepare for your camping vacation by setting up your tent in the yard as a “dry run,” so to speak, before you go for the trip. Examine the seams, zippers, and vents for signs of wear and tear, and make any required repairs. Then spray water over the top of the tent to ensure that it does not have any rips or tears that might enable water to seep into the tent inside. It is also possible for seams to dry out over time, causing the tent material to shrink and become more susceptible to moisture.

One sealer is designed specifically for seams, and another is designed for for flooring.

In order to preserve your tent in optimal water-repellent condition, these preventative methods should only be done every couple of years.

Pay Attention to Your Tent Floor

As a result, you don’t want your sleeping bags or other camping equipment to become damp on the floor. Keeping the floor warm and dry requires a few tactics, and they all begin with the way the tent is assembled. To begin, lay a sheet down on the ground where the tent will be set up to serve as a “footprint.” Ideally, you want a thick, heavy-duty tarp that is just a little bit smaller in size than the floor of the tent. Check to see that the tent’s floor is pulled flat and smooth when you’re adjusting it so that the walls can be tensioned appropriately when the tent is being set up.

Cover the mat with a blanket that is heavy enough to keep it in place, and then lay the sleeping bags on top of the blanket. A layer of insulation will be created between the ground and your sleeping space, which will keep dampness away from you and your bedding.

Setup Tips for Preventing Condensation

When you set up camp next to water, the evaporated moisture from the lake or stream will seep into your tent and ruin your camping experience. Make certain that your camp is situated far enough away from the city to avoid this problem. Pitch the tent on a modest incline if at all feasible to allow water to drain away from the structure. In the event that you’re planning on putting a footprint tarp below your tent, make certain that it is totally covered by the tent. If not, it will wick water to the underside of the tent and cause it to leak.

Bring Extra Tarps and Use a Large Rain Fly

If it happens to rain while you’re camping, it might make it more more difficult to protect the campers and tent from getting wet. Bring along a huge tarp to lay over your dining area so that everyone can enjoy a shaded gathering spot. Meals will no longer be an issue if it rains, and you will have a place to assemble and keep dry outside the tent if it rains. Apart from requiring a rain fly that extends well beyond the walls of the tent, the manner in which it is staked will have an impact on the amount of moisture that enters the tent inside.

This will have the additional benefit of boosting air circulation within the tent, which will help to prevent condensation from forming.

Wipe Down the Tent and Shake Off Water Frequently

Clean towels should always be kept on hand to wipe down the tent walls and the inside of the rain fly if necessary. As moisture builds, you may use this method to keep it from leaking and soaking your mattress and other belongings with water. Take another thorough wipedown just before retiring for the night, since dirt and grime will collect again throughout the course of your sleep cycle. In addition, rain and humidity might collect on the tent flap. Shake it off from time to time and make any necessary adjustments to the guy lines.

Don’t Store Wet Clothing or Gear in the Tent

The most effective strategy to avoid this problem is to do everything you can to keep your clothing and equipment dry in the first place. Whenever it comes to preventing moisture in goods and clothes, there are two things that immediately to mind: plastic bags. When it comes to staying dry when camping, plastic bags of all shapes and sizes are your best friend. Trash can liners are excellent backpack linings because they keep everything inside dry and prevent items from becoming damp. Those camp towels we recommended?

Storage in impermeable plastic bags is recommended because they will be ineffective if they become wet as well.

Also, stock up on inexpensive plastic rain ponchos that will protect you and your rucksack while trekking.

Never Cook Inside the Tent

Adding a large amount of moisture to the air within the tent in a short period of time is possible by cooking inside the tent. Cooking inside the tent, on the other hand, is not recommended for a variety of reasons other than dampness. Any form of heating device or flame within the tent is a fire threat, to begin with, and should be avoided. No matter how cautious you are, there is always a chance that something can catch fire, and it is simply not worth the risk to take the chance. Second, while you’re camping, you don’t want your tent to be the source of food odors, which might be unpleasant.

That is why bear bags are hung from trees to keep your food, with its enticing aroma, out of reach of bears and other scavengers while you are camping. When it rains at dinner, that cover over the picnic table will come in very handy.

Use a Dehumidifier

Chemical dehumidifiers and rechargeable dehumidifiers are the two types of dehumidifiers that may be used inside a tent. A product such as theDampRid Moisture Absorber Tub, which employs non-toxic calcium chloride salts to collect water from the air, is an example of the chemical kind. Alternatively, you may use the disposable hanging moisture removers, which can be hung in a convenient location on the inner tent supports. The use of a rechargeable dehumidifier, such as theWOHOME portable dehumidifier, is a more efficient technique to prevent moisture from forming within the tent.

Leave Shoes and Jackets Outside the Tent

Some tents include a vestibule, which is useful for removing shoes and storing wet coats and hats while you’re camping. Even if you don’t have one of them, a simple tarp that is placed just within the front of the tent flap would suffice. Extra material should be left over to anchor the vestibule’s sides at an angle to the left and right of the tent’s entrance, if necessary. At the cheap shop, you may get useful lightweight plastic containers for storing muddy shoes and ponchos that have been wet.

In addition, a short plastic step stool should be placed within the vestibule.

Prevention and Maintenance

Preventing condensation and keeping your tent comfortable and dry are the two most effective methods to avoid it from forming in the first place. Starting with clothes and sleeping bags that repel rather than absorb water, you can make a difference. Before you go camping, make sure your tent is free of leaks and that you have enough of tarps. If the weather permits, open the windows and let the fresh air to help remove some of the humidity from your tent. Keep damp clothing and shoes out of the house, and wipe off the surfaces as moisture accumulates.

7 ways to manage tent condensation

BACKPACKINGCAMPINGCONDENSATIONTENTSVENTILATION There’s nothing quite like the sound of raindrops falling on your tent’s roof or floor. However, moisture dripping from your tent’s roof is not a pleasant experience. Tent condensation is the worst enemy a camper can have. While it is hard to completely remove it, you can keep it under control by following the measures outlined in this article. Before we get into the specifics of how to keep tent condensation under control, let’s take a look at why it happens in the first place.

How tent condensation is created

It all boils down to the quality of your breath. While we sleep, we exhale up to one litre of moisture per person every night. When the heated water vapour comes into contact with the (relatively) chilly tent walls, it condenses and forms those annoying water droplets that we all hate. The next thing you know, you’re huddled in a steam room with your laptop. If at all possible, you should try to avoid condensation because a) it’s extremely unpleasant to be stuck in a damp or muggy tent, b) insulation doesn’t work as well when it’s wet, and c) if left unchecked, condensation can lead to mildew, which is bad news for your tent and possibly even your health.

Here’s what you should do (and what you should avoid doing) to keep tent condensation as low as possible:

1. Pitch your tent in the shade of a tree

When looking for a place to set up camp, you want to opt for a location that is the hottest and least humid possible. Hint: Look for a shaded location under a large, solid tree (one that is not likely to fall on you in the middle of the night—as opposed to one that is likely to fall on you during the day). Generally speaking, the air under trees is warmer than the air in a large open field or field of grass. As a result, the condensation will primarily condense on the leaves rather than on the surface of your tent.

2. Don’t camp right next to water

Setting up camp directly next to a babbling stream or waterhole may seem appealing, but it’s not a smart idea in the long run. The greater the distance between you and water, the greater the humidity. The higher the relative humidity, the greater the likelihood of condensation. You want to be near to the water, but not directly on the water’s edge, if at all possible. Choose a camping area that is a little further away from neighboring water sources.

3. Camp on higher ground

If you have the option of choosing between a low and a high location on the ground, choose the higher position. Cold air has a tendency to collect in depressions in the terrain. It is inevitable that condensation will form when the cold air meets the heated surface of the tent walls. Maintain in mind that heat rises, therefore it’s preferable to camp on somewhat higher ground in order to keep the temperatures inside and outside your tent in a comfortable range.

4. Don’t dry wet gear inside the tent

You should dry your clothing and shoes outside your tent if you get caught in a downpour. If you bring your moist garments into the tent, you will just increase the humidity in the environment. As a result, what happened? Not only do you wind up with dripping clothes, but you also end up with a dripping tent! Rather of putting the items in the dryer, hang them outside beneath a tarp (here’s a handy clothesline for precisely that). Also, remember to bring a change of clothes. Believe us when we say that it is well worth the extra weight.

5. Dry your tent off

Continuing the theme of rain, if it’s been pelting down and you don’t have time to let your tent dry out in the sun before you have to pack up and leave, at the very least give it a quick wipe down with a damp towel. Prepare to remove the rainfly from the inside tent (since it is likely that the rainfly will be significantly wetter than the inner) and put them in separate stuff bags. You should dry your tent in the afternoon sun as soon as you have a lunch break or arrive at your next destination.

6. Give your tent plenty of room to breathe

In the event that you have a double-walled tent (which is the norm these days), make certain that it is pitched appropriately to allow for optimal air circulation between the rainfly and the inner wall. When the walls of a tent come into contact with one another, condensation may quickly spiral out of control.

7. Ventilation is your best friend

Open all of the vents and windows in your tent, including the rain fly and vestibule door, to allow the air to circulate and dehumidify in your tent.

Don’t forget to open the windows and allow some fresh air in. Set up your tent such that the door opens in the direction of the prevailing breeze. If you follow the instructions above, the majority of the damp air should naturally leave from your tent.

But what if you could have a tent that could manage condensation for you?

The Tension Ridge, the hero invention of our Telos and Alto tents, has made it possible for us to develop tents that provide next-level venting that can be customized to meet your specific requirements.

Apex Vents for managing tent condensation

Given that hot air rises, it would seem logical to place vents at the highest point of a tent to maximize air circulation. Despite this, in all of our years of camping, we have yet to come across any other lightweight tents that accomplish this feat. So we’ve completed the task. Due to the absence of a mesh panel to maintain tension across the fly, the Apex Vent allows all of the hot, humid air to escape directly through the top of the tent, unhindered by any barriers.

Higher-wider doors means more ventilation

We were able to include larger doors into our tents because of the Tension Ridge. The larger doors not only provide a more broad view, but they also allow for more air to enter and exit the tent, making it simpler to enter and depart the tent.

Vertical walls create more breathing room

Unlike many other lightweight tents, which have sharply tapered walls, our tents have more vertical walls thanks to the Tension Ridge design. Because you will not be contacting the fabric inner or breathing directly onto the fabric, you will not be at risk of being wet from condensation, which will result in you and your gear getting wet.

Need some extra airflow? Here’s how:

You may open the Baseline Vent if it’s raining and the tent’s foot is facing the wind, which will help to dry the tent faster. You’ll be able to boost ventilation without mistakenly letting rain inside the house this way. When it’s hot and humid, point the tent’s head toward the wind so that the Apex Vent can sweep up all of the good fresh air and the natural pressure will drive it down and out via the Baseline vents. If it’s windy, point the tent’s head away from the wind. In addition, we’ve made it simple to open and close the vents from the inside of the tent as well.

We know moisture is the enemy

After a hard day of trekking, you want to be able to go back to your campsite as soon as possible so you can unwind. If, on the other hand, it is raining when you arrive at your campsite, you will have to wait for it to cease before you can begin setting up your tent. That’s certainly the case with many tents, to be honest. The rain fly on our tents is a separate piece of equipment. To ensure that everything stays nice and dry, you may actually put up the rain fly before the inner fly (including yourself).

Staying cool and dry through three seasons

Our tents withstand the rigors of summer, autumn, and spring (as well as mild winters). They are especially resilient in wet and humid circumstances. We found that when compared to other popular lightweight tents, the Alto and Telos provided 60% more ventilation and 31% less humidity, keeping you comfortable even when the weather is not cooperating with you.

Reduce tent condensation with Alto and Telos tent

When faced with a functional design dilemma, you have two options: either accept the situation or innovate to solve it.

After many nights of waking up to wet tents, we decided to develop in order to provide you two lightweight tents that are both cool and dry: the Alto and the Telos (Tents for Two).


Here are our best suggestions for staying dry on a rainy night! Condensation may be prevented most effectively by properly ventilating your tent and decreasing the interior humidity of your tent by fostering sufficient airflow. Examine your tent for low and high venting options, and then open them to allow the damp air to escape from the interior. Maintain complete zipped operation on mesh areas of the door if weather conditions allows. If weather conditions do not permit, leave the upper and bottom sections open.

  1. Check to see that no bags or sleeping bodies are obstructing the ventilation.
  2. Keep all of that squishy, dripping wet items out of the tent.
  3. A towel, boots, waterproofs, swimming trunks, and companions who are sweating.
  4. Awnings and tarpor hubs can be used to store damp equipment.
  5. Do you remember the extractor fan in your kitchen at your previous residence?
  6. Additionally, as the tent temperature rises, more moisture will be released into the atmosphere through evaporation and perspiration.
  7. Sheltered regions are more prone to the formation of condensation than open places.
  8. Humidity may be increased by rivers and lakes.

Take spare towels

Depending on the weather circumstances, it may be difficult to avoid condensation. Reduce it by following the methods outlined above, and keep a spare towel on hand to wipe it away quickly.

Eliminating Tent Condensation (And What Causes It) – Outdoor Horizon

When camping, there are a variety of obstacles to face. Everything from the trip to your campground to the bugs and insects you’ll have to deal with once you get there. The fact is, condensation is one of the issues that every camper must deal with at some time, so knowing how to reduce tent condensation is essential information. Using a dehumidifier or carefully selecting your tent’s location will help you avoid tent condensation. When there is a significant temperature differential between the inside and outside of a tent, condensation accumulates on the inside of the tent.

We’ll go into more depth about what causes tent condensation and the various methods for preventing and eliminating tent condensation in the sections that follow.

We’ll also explore several important techniques for preventing condensation, but first, let’s take a closer look at what condensation actually is.

What Is Tent Condensation?

Condensation happens when a liquid, in this example water, transitions from a gaseous/vaporous condition to a liquid one, as seen in the diagram. This transformation occurs when the warmer air vapor comes into contact with a colder surface, such as when you inhale warm humid air into the air in your tent. During the night, this air floats to the colder surface of the tent and undergoes a transformation from vapor to liquid.

How Does Water Change From Vapor To Liquid?

Vapor molecules are extremely fast-moving and may carry a lot of energy. When molecules come into touch with or near a colder surface, they tend to slow down and condense in the form of condensation. If you run your hand across the freshly generated water or bang your head against the tent walls, this newly formed water will disappear.

Relative Humidity

When the temperature outside the tent drops to a certain level, water vapor must condense and become a liquid. When you are sleeping or sitting in your tent, you are exhaling warm, wet air, which contributes to the increase in humidity in the surrounding air. As the temperature outside your tent drops during the night, the moist air you exhale comes into contact with the chilly tent surface, resulting in condensation on the tent surface.

What Causes Tent Condensation?

Tent condensation is influenced by the weather conditions in which it is set up. Usually, when you think of precipitation, you think of rain and snow. Conditions like these will have a comparable influence on whether or not you get condensation. First, the rain will boost humidity while simultaneously decreasing temperature, according to forecasters. If you are seated in your tent, you will notice that the interior of the tent is becoming stuffy. According to the preceding section, condensation will occur when the temperature lowers sufficiently to generate a temperature differential between the inside and outside of the tent.

Human Breath

When we are laying down, we exhale around 40 grams of water vapor every minute. 280 grams of water vapor will be produced by you if you are in your tent for the whole seven-hour period (or 9.8 ounces). This increased vapor contributes to the increase in humidity, which finally results in condensation.

Wet Clothes, Socks, And Boots

After a long day of trekking, your clothes and boots get dripping wet due to perspiration, rain, fog, and other elements. As a result, putting them in your tent for the night will increase the humidity level. As the temperature outside lowers and your garments attempt to “evaporate” the moisture, this will contribute to the formation of condensation.


Due to the fact that dogs do not perspire, they must cool themselves off through panting. After a hard day on the trail, you may find yourself with a panting dog next to you for the most of the night. When a dog pants, it exhales heat and causes moisture to evaporate, which cools the tongue and gradually reduces body heat over time as a result of the process.

The added moisture in the air contributes to the increase in humidity. Most dogs can sleep outside the tent depending on the time of year – something that should be done before your trip to ensure that your dog is comfortable. Nobody wants to sleep with the sound of a wailing dog all night!

Backpacks, Sleeping Bags And Pads

These things do not have a natural ability to transport moisture. However, if you do not dry your gear from the previous night, bags, pads, and backpacks might carry water back into the tent after a long day in the wilderness. Furthermore, if you are rained on throughout the day, it is doubtful that your backpack will be totally dry when you get at your campsite for the night. So, with all of this in mind, what is the best way to eliminate tent condensation?

How To Eliminate Tent Condensation

The diurnal temperature range (the difference between the highest and lowest temperatures in a single day) varies by geography and what are known as diurnal zones (difference between the maximum and minimum temperatures in one day). During the summer months of New Hampshire, the typical diurnal temperature range is between 20 to 23 degrees Celsius. As a result, with a temperature range that is quite narrow, you could expect less condensation. The increased humidity in the Northeast, on the other hand, creates a significant amount of condensation on your tent.

Because of the high humidity in the northeast, a tent may get very’stuffy’ on a summer trek, which makes it difficult to get a decent night’s rest.

This will assist you in making plans for your next vacation.

Tent Placement

When it comes to preventing tent condensation, the location of the tent may make a significant impact. The increased humidity around rivers and streams is due to the fact that they are moving. As a result, it stands to reason that setting up the tent near a river will enhance condensation!

In Open Fields Verse Under Trees

If you pitch your tent in the middle of an open field, the temperature will drop far more than if you pitch it behind a tree or at the border of a wooded area. It is recommended that you set up your tent under a tree in order to keep it warm during the night. However, keep an eye out for deadfalls and widow makers in order to reduce the likelihood of a branch falling on your tent as you sleep!

Rainy Days

Rainy days will create much higher levels of humidity and water vapor, which will result in a higher amount of condensation. So, in addition to the obvious advantages of camping during dry weather, you may also reduce the amount of condensation that accumulates in your tent by avoiding camping during rainy weather.


By ensuring that your tent has adequate ventilation, you may enhance the pace at which water evaporates and allow for the passage of humid air out of your tent. As a result, condensation is restricted. When you set up your tent towards the wind, you increase the amount of ventilation in your tent while also increasing evaporative cooling.

Other Ways To Eliminate Tent Condensation

Here are some other suggestions for reducing tent condensation:

  • Removing your backpack, damp clothing, socks and boots is recommended. Properly ventilate your tent– If your tent does not have adequate ventilation, it is generally a good idea to invest in a more suitable model. Cooking or boiling water in your tent increases the amount of water vapor in the air, which increases the amount of humidity in the air. Open your windows and your rainfly to help maintain a comfortable temperature and offer adequate ventilation. Position your tent so that it faces the wind. DO NOT light a candle inside your tent– While it may appear that doing so would assist to eliminate humidity and raise the warmth, doing so instead increases the chance of a fire. Do not make any contact with the tent walls. Even if it means pulling it out in the middle of the day when you are enjoying a picnic on the path, dry the tent in the sun. After a long trek, dry all of your belongings by the fire or in the sun. Remove and dry all sleeping materials before packing them into a daypack. It is recommended that you bring a “shammy” with you to dry damp parts on your tent. These are excellent for removing particularly moist portions of the tent before packing up for the day. Increase ventilation and air circulation in the tent by using a tiny battery-operated fan. Hold the tent taut– Holding the tent taut helps the hydrostatic head features to perform more efficiently and reduces the likelihood of your tent leaking.

Should You Use Tent Dehumidifiers?

It is possible to reduce tent condensation by using tent dehumidifiers.

Tent dehumidifiers have been increasingly popular in recent years. They work by reducing the humidity in your tent, as the name says. When the humidity is reduced, the likelihood of condensation when the temperature lowers throughout the night is reduced.

Chemical Dehumidifiers

Chemical dehumidifiers collect moisture from the air by using non-toxic calcium chloride salts (desiccants) as desiccants. They are useful in confined spaces such as a tent, but they are not reusable. During a hike, place them inside the tent and hang them from the tent supports to keep them dry.

Rechargeable Dehumidifiers

Dehumidifiers that are rechargeable, such as theVERITAS Small, Portable, Rechargeable, and Renewable Dehumidifier, may remove up to 150 mL of water vapor each day from the air. This should be sufficient to get you through the night comfortably, and it will also aid in the elimination of tent condensation. Because it is just 8.1 ounces in weight, it is ideal for short, humid backpacking excursions or vehicle camping.

Final Thoughts

Because of the colder temperatures outside the tent, condensation develops as a result of moisture accumulating in the humid air within the tent coming into touch with its frigid walls, which are caused by the cooler air inside the tent. The key to preventing tent condensation is to maintain the humidity inside the tent as low as possible while keeping it adequately aired.

How to Lower Humidity in Grow Tent When It’s too High

Home»Environment» The best way to lower the humidity in a grow tent when the humidity is too high 19187Views0 Humidity may be both a benefit and a disaster for an indoor grow system, depending on the situation. Just as with temperature, humidity has a significant impact on the quality and quantity of your indoor gardening harvest when it comes to quality and production. After everything is said and done, when the humidity in the grow tent rises to dangerous levels, it might result in the worst nightmare for a grower.

We hope you are not one of those people who would later come to regret spending all of their money, time, and effort because they were unable to deal with a scenario like this.

We’ve included both short-term and long-term solutions, as well as a list of causes that might result in damp air in the first place.

Why? Why? Why?

As a result, we’ve created a circumstance in which there is an excessive amount of humidity in the grow tent. The entire affair, on the other hand, did not happen out of nowhere. It must have had some cause for the high Rh level, and recognizing those reasons is critical to figuring out how to get the Rh level back down. Agreed? The following is a list of possible suspects:

Increased Transpiration

The size of a plant’s leaves increases in proportion to the size of the plant. Furthermore, it is a fundamental principle of botany that bigger leaves release more vapor into the atmosphere.

In the event that you do not adjust your ventilation system to the appropriate level, the humidity will rise instantly. This might also happen if you suddenly increase the number of plants in a container or garden.

Open Water Surfaces

Open water surfaces are a direct source of water vapor into the surrounding atmosphere. A nutrient reservoir, a moist floor in a room, or any other container of water can be used as a water storage container. If it’s in close proximity to an oscillating fan, the airflow across the surface will cause more water to evaporate, and then bang! The laws of thermodynamics are in effect.

Too Humid Outside Environment

The average humidity in Alaska is 77.1 percent, whereas the average humidity in Florida is 74.5 percent. The list goes on with the states of Louisiana, Mississippi, Hawaii, Michigan, and so on and so on. (The whole report may be seen here.) This discusses in great detail why growing in a grow room in these types of environments is difficult. Any small crack or leak in the insulation system between the grow room and the outside environment may result in a sudden and unexpected increase in the relative humidity.


The soil will get soggy as a result of overwatering the plants, which will also push the leaves of the plants to release more vapor into the air. Both damp soil and over-transpiring plant leaves have the potential to make the environment inside the grow tent uncomfortably humid.

High Humidity is Bad, Here’s Why-

A lack of humidity in a grow room can have a variety of negative consequences for the plants. However, having too much of it is not a good thing. When your grow environment becomes overly humid, here are some immediate results:

  • Unwanted biological development such as bud molds, powdery mildews, and other such organisms
  • Having an excessive amount of moisture in the air may encourage bud or blossom rotting, which won’t be seen until you’re at the harvesting stage. First, by inhibiting the capacity of the plant to take up CO2, and then by restricting photosynthesis
  • The plant’s ability to transpire further is hampered by vapor saturation of the air. This results in a drop in the total metabolic rate of the plant
  • Plants prefer humid air while they’re young, and less humid air when they’re old, according to the USDA. If the plants continue to develop under high humidity as they mature, the rate of their growth and the quality of their health will be hindered.

How High is ‘Too High’ for Grow Room Humidity?

As we all know, the degree of humidity fluctuates from one development stage to the next. As a result, it is not possible to designate a definite “Rh Percentage” as a distinguishing factor between an optimal and an excessively high humidity level. However, the general rule of thumb is that the entire range of humidity in a grow room should be less than 60%. A rise in the relative humidity level above 60% can cause a number of crop-related problems, as we described in detail in the preceding section of this article.

The Correct Humidity Levels for Different Grow Stages

According to what we now know, the degree of humidity fluctuates from one stage of development to another. In order to distinguish between an ideal and an excessively high humidity level, it is not possible to designate a set ‘Rh Percentage’ as a reference. Although it is recommended that the general range of humidity in a grow room be less than 60%, this is not always the case. A rise in the relative humidity level above 60% can cause a number of crop-related problems, as we described in detail in the preceding portion of this article: The following is a simple stage-by-stage chart of humidity ranges to help you understand what the strict Rh limit for each grow stage is:

Vegetation: Rh 40-60%

Because growing plant leaves need a sufficient amount of water in the air, the humidity level must be elevated.

Additionally, a percentage of the water intake is accomplished through the roots of the plants. However, because they haven’t fully formed yet, leaves must continue to take in water.

Flowering: Rh 35-50%

This is the point at which high Rh begins to manifest itself in negative ways. As a result, it is critical that the humidity does not rise from this point on. Molds, rotting buds, and other unpleasant things will begin to appear if this is not done. To ensure that the flowering stage begins successfully, the relative humidity should be maintained between 40 and 50 percent. However, after the buds begin to produce a crop, farmers reduce the percentage to 35-40 percent. And this must be done gradually, so that there is no significant, rapid decline in the Rh.

Harvesting/Drying: 30-40%

Crops begin to dry at this point, which leads to the harvesting of the crop. However, we must maintain a humidity level of 30-40 percent in order to prevent the buds from drying out too quickly. Some growers prefer to maintain a little higher humidity level (50 percent) in order to allow their buds to dry more slowly. This, in any case, enhances the overall quality of the cured buds.

Germination/Cloning Vegetation Flowering Harvesting/Drying
75-85% Rh 40-60% Rh 35-50% Rh 30-40% Rh

How to Decrease Humidity in Grow Tent/Room?

When it comes to figuring out how to reduce humidity in a grow room or room, things aren’t always easy to cope with. Any action will require sufficient time to bring the Rh down. As a result, you must stick to the shortest routes available. The few of solutions that we’re about to cover are designed specifically for circumstances like this. Here’s everything you need to know-

Use A Dehumidifier

It should go without saying that in order to reduce humidity, you will need to rely on our trusted ally, the grow room dehumidifier. Prior to purchasing a dehumidifier, take a moment to consider the appropriate size for your grow room layout before making your purchase. So, what exactly qualifies as a decent dehumidifier that can remove the exact amount of humidity that you require? Some points to think about are listed below.

  1. Dehumidifying capacity is critical, and it should match the requirements of your grow system exactly. According to the manufacturer, it is intended to absorb and expel the same quantity of vapor that your plants exhale via their leaves. There is a limit to how much may be held in a pint
  2. You should check to see that your dehumidifier can be connected to your drainage system if you live in a humid climate. It should have a water tank that is enough in size. It should be equipped with an automated timer or an automatic shut off mechanism (when the tank is completely full)
  3. It should be considerate of the power bills’ budget.

Once you’ve selected the appropriate size dehumidifier, you’ll need to ensure that it is installed in the proper location. Also, avoid connecting these dehumidifiers to electrical extension cords if at all possible.

Use An Air Conditioner

Knowing that the temperature and humidity of a grow room are intertwined is not a surprise. When the temperature rises, the capacity of the air to contain water vapor increases as well, and you will see a direct increase in the Rh levels in your room. As a result of decreasing the temperature, you will be able to eliminate a significant amount of humidity from your grow tent or growing environment. Having said that, selecting the appropriate size of air conditioning units is critical. Otherwise, it will either result in condensation or will be unable to maintain control over the temperature and humidity levels in the room.

Passive Ways

When it comes to smaller grow systems, such as 44, 55, and 88 grow tents, utilizing a dehumidifier or air conditioner is not a suitable alternative for reducing humidity.

Fortunately, there are a number of passive solutions that are effective in dealing with this problem in indoor grow systems. We’ve compiled a list of three actionable passive methods for accomplishing this. Take a look at this-

Boost the Ventilation Up

When it comes to passive methods of decreasing the humidity level, increasing air circulation is at the top of the priority list. One of the primary reasons of excessive humidity buildup in your grow room is the failure to properly vent damp air out at a sufficient rate. Simply said, substituting the humid air for fresh, ambient outside air will lower the Rh percentage by a significant amount. In the event that you find yourself in a high humidity condition, the following steps should be taken to improve ventilation:

  • Increase the size of your intake hole or make a new one. This will allow for more air to enter the room while also increasing the efficiency of an exhaust fan. If you want to utilize an intake fan instead of holes, increase the power (CFM) of the fan. Instead of simply employing oscillating wall fans to circulate air around the grow room, adding floor fans as air circulators throughout the grow room is a good option. These fans have the ability to draw air through the plant canopy, ensuring a proper interchange of old, humid air with new, dry air. Make use of an atmospheric controller that has humidity settings to reduce the risk of fire. It will automatically adjust the exhaust/inlet fan speed in accordance with the relative humidity in the room
  • And In responsible of removing the humid air should be inline fans. Make certain that the fan is strong enough and has the same diameter as your ducting, which is more critical. Keep a watch out for how effectively this buzzy thing is at reducing its noise level

Use A Thermostatically Controlled Block Heater

Do you have a high level of humidity in your grow tent at night? Increases in Rh levels and condensation are more likely to occur during the dark hours as opposed to the light hours, according to research. The temperature decreases as soon as the lights are turned off. When the temperature drops sufficiently, moisture will begin to accumulate around the lights, which is referred to as humidity fluctuation in this context. Remedy? When the lights in your grow room are turned off, use a thermostatically controlled block heater to keep the temperature near to the level when the lights are turned on.

Defoliate the Plant Leaves

We’ve already noted that when plant leaves develop in size, they become a more significant source of water transpiration into the surrounding atmosphere. Result? The humidity in the grow chamber rises quickly. You can defoliate some of the exceptionally huge plant leaves as a passive solution for bringing the humidity level in the grow tent down. Whenever you are removing leaves, make sure to leave enough for the plants to continue their usual operations, such as photosynthesis. By comparison, it is a relatively inexpensive method of lowering humidity in grow tentas that works fairly well.

Things to Do to Avoid Further Raise in Humidity

What can I do to permanently reduce the humidity in my grow tent? Here are some steps you may do to keep the humidity in your ingrow tent from rising any further:

Don’t Depend on One-dimensional Ventilation

One of the fundamentals of humidity control is that, if appropriate ventilation is provided throughout the grow room, the air will never get saturated with water vapor. The oscillating fans alone will not be sufficient to ensure that this occurs. Because they can only lower the temperature of the plant canopy, they are not very effective. So, what is the best way to create a multi-dimensional ventilation system? As a result, here are some recommendations: –

  1. If you’re growing in a tent, make sure there are many intake holes. In the event of a room, source air should be provided by more than one intake fan. Maintain appropriate air circulation across the plant canopy, including the bottom (with floor fans) and top (with wall-mounted oscillating fans) sections. Allowing the CO2-rich, heavy air to accumulate on the floor is not recommended.

Deduce Exposed Water Surfaces

It’s a very easy and inexpensive hack to do, but it turns out to be really successful in terms of lowering the humidity in the grow room. And that is to determine whether or not there are any exposed water surfaces in the grow chamber. How did these open water surfaces get there in the first place?

  1. Water that is stagnant yet does not puddle on the ground
  2. Reservoirs for water

To deal with the first, you must make certain that a sufficient drainage system is in place throughout the whole grow system. For the second, just place covers over each and every water reservoir you have in the room to bring the situation to a close.

Insulate Your Grow Space from Outside Humidity

Occasionally, you will notice that the humidity level continues to rise regardless of how much effort you put out after placing it down. Perhaps this is due to the fact that your indoor garden is in close contact with an excessively humid outside environment. It’s possible that the location where you reside has more humidity than usual, just like it does in New Mexico or Colorado.

Commercial growers frequently utilize barriers such as foam insulators and other similar materials to prevent this from occurring. When it comes to growing in a grow tent rather than a grow room, however, insulating the growing space becomes much simpler.

Use Soil That Absorbs Vapor

The use of soil that can absorb water and retain the Rh beneath the grow tent can be a useful step in eliminating humidity in the grow tent. Sandal soil is an excellent example of this type of soil. Make certain, however, that your plants will not have any difficulties growing in such mediums.

Use The Right Size of AC Units

Both big and undersized air conditioning systems have the potential to cause an increase in temperature and humidity. With large air conditioning machines, the dead band is quite brief, resulting in an increase in humidity in the surrounding air. And, on the other side, small air conditioning systems cause wilting, which is a concern for indoor plants. One of the factors that might cause a troublesome environment for the plants is a high degree of humidity. What’s the gist of it? Always make sure that the air conditioning units are the proper size so that they can operate consistently for the greatest amount of time.

Keep an Eye on Your Humidity Level

Using this method does not constitute a ‘prevention’ to lower humidity in a grow tent. However, by utilizing a hygrometer, you can keep track of the exact humidity level that your tent or room is experiencing. In the market, there are thermometer-hygrometer combos that may be purchased. You can kill two birds with one stone if you have one of them hanging on the wall of your grow tent. To ensure that the humidity in your grow tent does not get too high, here are some of our favorite digital thermometer-hygrometer combos.
