What is a Humidifier?
The humidifier is a device that is used to increase the moisture in a compacted space. It is used in grow rooms, offices, restaurants, greenhouses, grow tents, and many spots to control the air’s humidity.
The humidity percentage of a grow room is one of the critical factors for the plants. Humidity is connected with the temperature, air balance, and so on. So, it is vital to maintain the humidity of the grow room, and for this, you need a humidifier.
Why Do You Need the Humidifier for Grow Room?
In the grow room, it is essential to maintain moisture, temperature, and air balance for the plants. For this reason, you need to control the humidity.
You can control it in various ways. But using the humidifier can lessen your labor and other issues.
Here I have discussed those points separately for easy understanding.
Easiness of the humidity control
By using a humidifier, you can easily control the grow room humidity. You can increase humidity by boiling or taking other manual steps, but it may not work correctly. Another hand, using a smart humidifier, you can do the task comfortably.
To maintain temperature issues
Excessive or low temperatures can bring bad results to the grow room. Temperature is related to humidity. If the humidity level is unsuitable, the temperature will not be healthy for the plants.

To control air balance
Humidity level shows the amount of moisture in the air, which is a fundamental factor. So, by using a humidifier, you can control the moisture level, maintaining a healthy ratio.
To remove some unwanted particles from the air and the water
Some humidifiers remove dust, airborne impurities, and pollen particles from the air and also destroy the harmful elements of the water. After that, they spread out the mist in the air. This makes the air clean and more suitable for the grow room.
To prevent the humidity related problems of the plants and ensure natural growth
Excessive or low humidity can create many problems for plants. Plant’s growth becomes affected. The leaves may become dry or get some diseases. Root’s growth becomes stunted.
For this reason, it is essential to control the humidity of the grow room.
Different Types of Humidifier For Grow Room and Grow Tent
For the grow room, there are five types of humidifiers available. They are also different in shapes and sizes. Here I have given short descriptions of this humidifier to understand what kind of humidifier you may need for your work.
It will also become more comfortable for you to choose the right one from them.
Ultrasonic humidifier
For the grow room, the ultrasonic humidifier is one of the best humidifiers to choose from. It can produce both warm and cool mist by vibrating at a super-high frequency.
For the warm mist, water is heated before creating the mist. The mist evaporates in the air and increases the humidity.
For the cool mist, water is kept at average temperature and evaporates the water by ultrasonic vibrating.
A silent fan takes an important part here. It spreads out the moisture in the room. It also keeps the humidifier cool.
Pros:
- It creates low noise
- Releases fog
- It doesn’t need to change the filter regularly
- Easy to maintain
- Comfortable management system
Cons:
- You cannot use normal tap water
- Comparatively high in price
Cool mist humidifier
This type of humidifier releases cool mists by drawing the air from the room and blowing it over the moistened water. This process increases the humidity and removes the heat from the air. For this reason, it is called a cool mist humidifier.
Pros:
- Easy to clean
- Shows high-efficiency rates in large spaces
- It is very effective in warm weather.
- Simple operating system
Cons:
- It is noisy at the operating time
- Maintenance cost is comparatively high
- The filters need regular changing to protect the humidifier from some problems.
Warm mist humidifier
It is the most common type of humidifier. The warm mist humidifier releases warm mist in the air. It heats the water at a certain level of temperature and blows the hot mists in the air.
The hot mists evaporate and increase the humidity of the room.
Pros:
- The price is quite reasonable
- The noise is comparatively low than the cool mist humidifier
- Destroy the bacteria and other harmful organic compounds, which is bad for the plants of the grow room.
- Easy to run
Cons:
- More difficult to clean
- Warm mist humidifier covers only tiny space
- Requires more electricity
- It needs regular maintenance, which increases the cost
Evaporative humidifier
These types of humidifiers use water from the tank and soak a piece of material. A fan is used to blow the room air over the wet material, and by this, water becomes vapor.
This is likely to the cool mist humidifier. The vapor increases the humidity of the dry air.
Pros:
- It is cheap
- Its filters prevent microorganisms, which are bad for the grow room
- Easy to maintain
Cons:
- It requires regular cleaning
- The filters have to be changed frequently
Air washer humidifier
It is one of the advanced humidifiers. The air washer humidifier adds moisture to the air and cleans the air by removing waste particles.
It mainly removes airborne impurities, dust, and pollen particles from the air. It produces cool mist only. Air washer humidifier can cover large areas.
Pros:
- It produces low noise at the time of operating
- Capable of covering large areas
- Makes the air more suitable
- Comfortable to operate
Cons:
- It has a problem with the water dust
- Regular maintenance is required
- The price of the humidifier is comparatively high
How to Choose the Best Humidifier?
This is one of the main problems that you have to solve first. You can find different types of humidifiers in the market, but you have to choose the right one for your grow room. They also have different shapes and sizes.
To choose the best humidifier for your grow room work, you have to consider some critical factors. Your room size, surrounding weather, budget, maintenance system capability, and type of plants you have chosen are those factors.
Here I have discussed some steps to consider while selecting a humidifier for your grow room.
Size of the grow room
It is ideal to consider the space size of the grow room before going to a humidifier. Here is some approximation that may work efficiently for your grow room.
- Small humidifiers for the grow rooms that are about 300 square feet.
- Medium humidifiers for the grow rooms that are about 350-500 square feet.
- Large humidifiers for the grow rooms that are about 550-1000 square feet.
Cool mist humidifier vs. warm mist humidifier
It must be settled by the surrounding weather of your grow room. For cold weather, you have to choose the warm mist humidifier. And for the warm weather, you have to select the cold mist humidifier.
Otherwise, your purposes will not become successful. It also depends on what types of plants you want to cultivate in your grow room.
Mineral Dust
It depends on the mineral you used for the humidifier. If the mineral contains too much dust and microorganisms, it is ideal to use the evaporative humidifiers. It destroys these wastes and cleans the water before evaporation. Otherwise, you can use the regular humidifiers for the grow room.
Automatic vs. manual system
If you prefer the automatic system, you may choose the ultrasonic humidifier and the air washer humidifier because they provide more automated features than others.
If you prefer the manual system, you may choose the cool mist humidifier, warm mist humidifier, or the evaporative humidifier.
Cleaning and maintaining
Cleaning and maintenance issues are essential for this process. It is ideal to choose the humidifier that needs less cleaning and maintenance. This lessens the workload and cost.
The humidifier needs regular maintenance, and changing may problematic for your work. Ultrasonic humidifier and the cold mist humidifier needs less cleaning and maintenance.
Level of noise
All the humidifiers make some amount of noise. Some of them create more noise, which may be very painful for you. But it varies from person to person.
If you want to choose a less noisy humidifier system, select between the ultrasonic and evaporative humidifiers. Otherwise, you can select it from the cold mist humidifier and the warm mist humidifier.
Cost & budget
It also differs from person to person. Before buying, you have to survey the market and compare your budget for the humidifier you want to buy. Always choose the humidifier that suits your budget.
When you use the humidifier, you have to bear the maintenance cost and the changing parts expenses. Try to select the humidifier that needs less cost of maintenance and other expenses. Otherwise, it can affect your profits.
Why Is Humidity Important for a Grow Room?
It means the volume of water vapor consists of a specific area’s air. The humidity of a particular area varies with the temperature. It is not controlled automatically in the grow rooms.
If the plant’s vapor pressure is more than the surrounding air, the plants will release more water for its body or vice versa. For this reason, you need a humidifier to manage the humidity of your grow room.
Proper humidity is a must needed thing for every plant on earth. So, for your grow room, it is important to understand what real humidity is. For easy understanding, I have divided the whole concept into three parts.
Humidity & plants growth:
Plants growth depends on the humidity level of the air. For the normal growth of the plants require proper photosynthesis, transpiration, and gas exchange process. These processes mainly depend on the humidity of the air.
If there is too much humidity in the air, the transpiration and the gas exchange process will become slow and vice versa. So, for the plants’ regular growth, you have to keep the idea humidity for your grow room.
Humidity levels:
- 10-40 percent: It is the lowest level of humidity. At this level, the air is dry, and the plants can hardly survive.
- 40-60 percent: It is the average humidity for a grow room. Most of the plants can grow excellently in this condition. But some plants cannot grow well.
- 60-80 percent: This level contains the optimum percentage of humidity. This level is perfect for a grow room, but it is challenging to maintain it in a grow room.
- 80-90 percent: This is the highest humidity level. Tropical plants can grow well in this condition. Other plants may face troubles in this situation.
Common humidity related problems of the plants
Humidity problems of the plants happen for the excessive amount or poor amount of humidity. It is better to understand if we separate them and then discuss the matter.
When the humidity is at the lowest level, the plants will become dry, and the color of the leaves will be changed. The attack of some micro-bacteria may occur. So, the plant’s growth becomes hampered.
When the humidity is at the highest level, some grey mold may appear in the leaves, the nutrient process gets hampered, and root diseases happen.
