Indoor plant growers understand the importance of maintaining proper temperature and humidity levels for their plants to thrive. If you’ve noticed your plants showing signs of dryness such as curling leaves, it may be due to low humidity levels in your grow tent.

To ensure the success of your plants, it’s crucial to learn how to increase humidity. The ideal humidity range for growing plants is between 45-75%.

If your grow tent falls below 20-40%, it’s time to take action to raise the humidity. Not doing so can lead to stunted growth, poor development, and lower yields. You can increase humidity using a humidifier or by implementing simple tricks using household materials.

In this post, we will discuss various cost-effective methods for increasing humidity in a grow tent or grow room. These methods have been tried and tested over time, and have proven to be effective in maintaining the ideal humidity levels for indoor plant growth. We will explore the different options available for raising humidity and the pros and cons of each method. Whether you are a beginner or experienced grower, this guide will provide you with valuable information on how to increase humidity in your grow tent or grow room.

Humidity Basics

When it comes to indoor gardening, relative humidity (RH) is the most important measure of humidity as it tells us how much water vapor is present in the air compared to the maximum amount that air can hold at a specific temperature. This is the type of humidity that plants need to thrive.

A hygrometer is a tool that can be used to measure relative humidity, and it should be an essential part of any indoor gardener’s toolkit. It’s important to keep an eye on the humidity levels in your grow tent or grow room, as low humidity can cause stunted growth, poor development, and lower yields in your plants.

By using a hygrometer and implementing the methods discussed in this post, you can effectively increase humidity and provide your plants with the optimal growing conditions they need to thrive.

It’s important to note that different plants have different humidity needs and can thrive at varying relative humidity levels. However, the temperature in your grow tent also plays a crucial role in determining the optimal humidity range for your plants.

As the temperature increases, the air can hold more water vapor, and therefore, the ideal humidity level for your plants will also change. For example, if your grow tent is at a higher temperature, your plants may require a higher humidity level compared to if the temperature was lower. It’s essential to monitor both temperature and humidity levels in your grow tent or grow room to ensure that your plants have the optimal growing conditions they need to thrive.

Consequences Of Low Humidity In A Grow Tent

It’s important to understand the role of water in plant growth and survival. Plants absorb a large amount of water through their roots, with about 95% of it going towards maintaining the plant’s vascular structure and exiting through the stomata, while only about 5% is used for building new cells.

When the air is dry, and the temperature is high, this creates a high vapor pressure deficit between the leaves of your plants and the air. This means that your plants have to work harder to exchange gases through the stomata, exposing them to the dry conditions of the outside world. In an effort to get more moisture, plants will put more pressure on their roots to take up water and counteract the humidity deficit. This can lead to plant stress and dehydration, which can cause the stomata to close and the plant to be unable to get more water.

Low humidity levels can also lead to an excess of nutrients in the water taken up by the roots, which can burn the tips of the leaves. In addition, lack of humidity poses the possibility of plant desiccation, making the plant more susceptible to infestation by insects such as molds, white powdery mildew, and spider mites. To avoid these issues, it’s essential to monitor and maintain the ideal humidity levels in your grow tent or grow room to provide the best growing conditions for your plants.

Importance Of High Humidity In A Grow Tent

For new indoor growers, the idea of high humidity levels may seem intimidating, but experienced growers know that high humidity can be beneficial for the growth and development of plants. By exposing your growing plants to relatively high humidity, you are providing them with the necessary water they need to survive.

Plants absorb water through their roots, but they can also take in water through their leaves and stem. This occurs when the plant takes in water vapor from the air through tiny openings on the leaf surface, called stomata. Without sufficient humidity, plants will not have the opportunity to absorb enough water for their full development and growth.

It’s important to note that while high humidity is beneficial during the growing phase, it’s important to maintain the right humidity levels that are suitable for the specific plants you are growing and also that humidity levels should be reduced during the flowering stage to avoid mold and fungus infestation.

Things To Review

Humidity is an important factor in the growth and development of indoor plants. It is important to maintain relative humidity levels between 45% and 75% in a grow tent or grow room. Low humidity can lead to stunted growth, poor development, and lower yields. To increase humidity, growers can use a humidifier or simple tricks using materials found in their home.

The size of the grow tent and the stage of plant growth also play a role in determining the ideal humidity level and temperature. It is recommended to use a digital thermometer and hygrometer to track and maintain the ideal temperature and humidity levels for your plants.

What Is The Right Humidity Level?

It is important to note that these are general guidelines and that different plant species may have different requirements for humidity. It is always best to consult the specific needs of the plants you are growing and make adjustments accordingly. Additionally, it is important to monitor humidity levels regularly and make adjustments as needed to ensure optimal growth and health of your plants.

How Grow Tents And Relative Humidity Can Help You Grow Plants

Some ways to increase humidity in a grow tent include using a humidifier, placing a tray of water near the plants, misting the plants, using a humidity dome for seedlings and clones, and using peat moss or coco coir as a growing medium.

It’s important to monitor the humidity levels and make adjustments as needed to ensure the optimal growing conditions for your plants. Additionally, proper ventilation and air circulation are also important to maintain the humidity levels and prevent mold or mildew growth.

Where to place dehumidifier in grow tent?

Dehumidifiers are a great way to control humidity levels in a grow tent or grow room. High humidity can lead to a variety of problems such as mold and mildew growth, musty odors, wood rot and more. Placing a dehumidifier in the grow tent can prevent these issues and improve the overall air quality in the space.

This, in turn, can benefit the plants by providing them with a more optimal growing environment, which can lead to better growth and yields. It is also important to note that when using a dehumidifier, it should be placed in a location where it can easily circulate and dehumidify the air throughout the entire grow tent or grow room.

Why do you need a dehumidifier in grow tent?

A dehumidifier works by removing excess moisture from the air, helping to maintain the desired humidity level. It can be placed in the grow tent or grow room to keep humidity levels in check. This is especially important during the flowering stage, when plants are most sensitive to changes in humidity.

High humidity levels can lead to mold and mildew growth, which can damage or kill your plants. In addition, a dehumidifier can help reduce the risk of pests and disease, as well as improve the overall air quality in the grow tent. It is important to monitor the humidity levels in your grow tent and make adjustments as needed, using a hygrometer and a dehumidifier as necessary.

Where should you put a dehumidifier in grow tent?

The air filter in the dehumidifier is an important aspect to consider during installation. The air filter is responsible for trapping dust and other particles in the air, and preventing them from entering the dehumidifier. It is important to regularly check and clean the air filter to ensure that the dehumidifier is operating at maximum efficiency. The air filter should be placed in an area where it can easily be accessed for cleaning and replacement.

Another important aspect to consider during dehumidifier placement is the exhaust or drainage system. The dehumidifier must be placed near a drain or have a hose that can be attached to a drain in order to properly dispose of the collected moisture.

The placement of the dehumidifier in the grow tent is a crucial aspect to consider. Factors such as the size of the grow room, number of plants, airflow and ventilation, and the capacity of the dehumidifier should be taken into consideration. Proper placement can ensure that the dehumidifier is operating at maximum efficiency and effectively controlling the humidity levels in the grow tent. Additionally, the air filter and exhaust or drainage system must be placed in an accessible and convenient location for regular cleaning and maintenance.

How do you dehumidify a grow tent?

All of these steps are important in maintaining the proper humidity levels in a grow tent or grow room. Overwatering can lead to excess moisture in the air, which can lead to mold and mildew growth. Properly disposing of stagnant water and investing in a powerful whole room dehumidifier can help to control humidity levels.

Proper ventilation and air flow is also essential in keeping humidity levels in check. Adding fans, creating air holes, and setting up an air conditioner can all help to improve air flow. Insulating and sealing the grow room or tent can also help to prevent fluctuations in temperature. Additionally, using absorbent soil and plant defoliation can help to control humidity levels, as can using the right grow equipment.

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

It is also important to note that while a dehumidifier can help control the humidity levels in a grow room, it is not the only solution. It should be used in conjunction with proper watering techniques, proper ventilation and air flow, and other methods to control moisture and temperature. Additionally, it is important to regularly maintain and clean the dehumidifier to ensure it is functioning at its optimal level. Overall, the placement of a dehumidifier in a grow room is just one aspect of maintaining a healthy and conducive environment for plant growth.

What happens when you place dehumidifier outside the grow tent?

Placing a dehumidifier outside a grow room is not unusual. It might be the best option to ensure dehumidification is carried out properly. Installation of dehumidifier outside grow rooms is similar to setting up carbon filters outside grow tent. However, this process comes with two options and you can answer to whichever works best for the well-being of your plants. One is the whole room dehumidifier, and the second is ducted dehumidifier. Consult with your professional if your need to setup a dehumidifier outside the grow room in your home.

How long should a dehumidifier run in a grow tent?

It is recommended that growers run their dehumidifiers 10 to 12 hours per day (or more) in a grow tent. This depends on the unit capacity of the dehumidifier, the number of plants, existing RH in the air, and other criteria. Whether one deals with whole room dehumidifier, ducted or suspended dehumidifier, how many pints of water is removed per day, etc., are also other factors tied to it.

How to choose the size of dehumidifier for grow tent?

In summary, to choose the right size of dehumidifier for your grow room, you should consider the amount of water that needs to be removed from the environment and the BTUs produced by the unit. The dehumidifier should be able to remove the amount of water that your plants transpire, which is 97% of their water intake.

Additionally, the unit should not produce too many BTUs, as this can create an unhealthy environment for the plants. It is also important to keep in mind that the size and efficiency of the dehumidifier should also depend on other factors such as the size of the grow room, the number of plants, and the ventilation and airflow in the space.

FAQ Section

How does the location of my dehumidifier in my grow room affect my environment?

Having a dehumidifier in the right place in a grow space can help a grow environment tremendously. Adversely, a dehumidifier in the wrong place can result in little to no effect. In the wrong position, a dehumidifier can struggle because of things like cold air from an AC, poor spacing of dehumidifiers, not enough room from the wall, too far from the plants (if the room is very tall).

What is the optimal location to reduce humidity?

This depends on how many dehumidifiers you need. If only one is needed, centrally located in the room, above or next to the lights is generally the best placement. There are variables that affect placement, such as room height and airflow. For example, when a room has a low ceiling you might not be able to hang your dehumidifier. In this case, we might recommend a floor placement or under a table. We recommend reaching out to us or a licensed HVAC professional to ensure correct placement.

What is the optimal location to increase airflow?

Place your dehumidifier at the recommended distance away from the wall to eliminate “choking” of the machine. Also, placing it away from direct flow from an air conditioner or heater will help with airflow.

Each dehumidifier has different wall spacing guidelines. Make sure to reference the owner’s manual if you plan to place near a wall. For example, Quest’s 5 Series dehumidifiers should be a foot from the wall.

What advantages do different potential locations offer?

There are multiple options for placement. The decision comes down to the grower in each individual space. Every grow room is slightly different.

Some growers prefer to have them under their tables. This is perfectly fine. They will perform well as long as there are no obstructions to the supply and return openings.

Some growers do not have the room to hang their dehumidifiers in the middle of a room and put them at the end instead. This is also fine as long as they are not near the AC and not restricted.

Lastly, there are growers that simply do not have any space for more equipment and duct their dehumidifier from outside the room. This is a great solution for people who have limited space. The only thing to avoid is running the duct too long. You want to keep the duct length under 30 feet.

If multiple units are required in one room, how should growers space them out to maximize efficiency?

The best way to place multiple units is to space them out evenly throughout the room. This eliminates the possibility of humid pockets.

How many fans should cultivators add to maximize airflow and dehumidifier efficiency?

A: This is grower preference, but we recommend as many as you can without damaging the plants. More airflow the better is our recommendation; just not at the cost of the health of the plant. You want to see plants “dancing” from the airflow but you don’t want to see severe bending of the entire stalk.[1]Grow Tent dehumidifier placement
