If you have had some experience growing plants, you would have noticed that during winter, your plants look dull and wilted. That is because of the dry air that continually interacts with the plant.

This is not only restricted to the winter season. Generally, plants need a level of moisture to thrive at all seasons.

Well, the good thing is that introducing the best humidifier for plants will help supply enough moisture or humidity into the air, thus lowering the rate of evapotranspiration in the plants.

What Is Humidity?

Understanding what humidity is will help to determine how to condition the environment to favor certain plants.

Simply put, humidity is the amount of water vapor or moisture present in the air. Vapor is water in its gaseous state.

There are two types of humidity, and we discussed them briefly.

Relative humidity

Relative humidity (RH) is how much humidity present in the air compared to how much there could be at a certain temperature.

Absolute humidity

Absolute humidity (AH) is how much water is in a cubic meter of air.

Typically, the higher the temperature of an environment, the more the water vapor it can hold. This statement can only be valid if there is the availability of water in the environment.

So it is almost impossible to increase the humidity of an environment without increasing the temperature. This is why plants that require high humidity also need higher temperatures too.

What is Plant Humidifier?

Plant humidifiers, just like the standard convection humidifiers, are devices that add sufficient and controlled moisture to the surrounding.

They have a compartment where the water goes in. When connected to an electric outlet, it dissipates water vapor or steam to increase moisture levels in the air.

Benefits of Plant Humidifiers

Benefits of Plant Humidifiers

Now, let’s look at some of the benefits of plant humidifiers:

Aids the health of leaves

Humidifiers help significantly in healing plant leaves and making them vibrant and smooth. When the leaves are healthy, the tipping of leaves is avoided. And if you may know, the leaves are responsible for manufacturing food for the entire plant.

Provides warmth for healthy growth

Humid air is always warmer than dry air like the one experienced during winter. A humidifier doesn’t just only emit vapor but also increases the temperature of the surrounding.

So you will not need to turn on the heater. This, in turn, helps save cost in utility bills since humidifiers consume lesser power.

It helps enhance reproduction

The effects of low humidity in plant’s bud are discoloration and eventually leading to falling off. The buds of plants are responsible for reproduction. When they fall off, it means that the reproduction of plants will not occur.

With humidifiers, the plants are supplied with sufficient humidity needed for the buds to thrive and reproduce.

Why Do Some Plants Need Higher Humidity?

Most plants need a higher level of humidity to grow healthy. This is because when the surrounding air is dry, the pores through which the plants breathe lose most of their moisture.

Unfortunately, the plants cannot replace the loss of this water themselves through their root. After all, even the soil which they are rooted in has also got rapid evapotranspiration.

The thinner the leaves, the less water it is capable of holding. So the thinner the leaves, the greater the need for higher humidity.

All plants are different; they will require different levels of humidity. The following are some of the recommended humidity for common house plants.

  • Orchids – 40-70%
  • Most other houseplants: 40-60%
  • Ferns – 40-50%

What to Consider While Buying a Plant Humidifier | Buyer’s Guide

Disadvantages of Plant Humidifiers

Humidifiers have a range of uses. While so many persons buy them to humidify their homes to have a conducive atmosphere during winter, buying humidifiers for plants is a different case.

To buy the best humidifier for plants, the following factors should be taken into consideration.

Size of the room

This is one of the most important factors when buying humidifiers in general. You should have a knowledge of the size of your room or the size of the plant house you intend to install a humidifier.

If a humidifier cannot cover your room, then the plants will die from insufficient humidity. In the same way, if the humidity offers too much coverage than the size of your room, the humidity becomes too much for the plant.

The ideal humidity for a plant is between 50%-60% humidity. For a room around 300 square feet, a small humidifier is required. If the room is between 350 – 400 square feet, a medium-size humidifier is required. From 500 square feet size room, a larger humidity is recommended.

Always endeavor to check the coverage of the humidifier and match it with your room size.

Type of humidifier

There are about 4 types of humidifiers, and we discussed them extensively in the next section below.

Both of them use different techniques to release moisture into the air. Understanding the difference between them will help you choose the right one for your plant so that they won’t get affected by bacteria, mold build-up, or dry out.

Tank capacity

If you are buying humidifiers for home, then it is going to be a small or medium-size one that uses a water tank. The larger the tank, the less frequent you will have to refill the tank.

Typically, anything from 1 gallon (4L) is an excellent choice because it will last for at least 12 hours and up to 24 hours.

Larger and heavy-duty humidifiers can be connected to the water supply. So you do not need to refill often.

Noise level

If you have a humidifier in the same room where you live and sleep, then you will want to buy a quiet one.

They can be noisy, especially the larger ones. However, if the grow room is separate from the living area, then this will not be a problem.

Filters

Not all humidifiers come with a filter or design for attaching a filter. But they are crucial, especially for homes or gardens where the water being supplied is hard or contains minerals.

The problem with filter humidifier is that you get to change them at least every 3 months. This can be avoided if you decide to use distilled water.

However, if you hate the idea of filters and don’t want to experience the stress associated with them, then you can go for filter-less humidifiers.

Speed settings

The speed settings of a humidifier determine the moisture level. Most of the humidifiers today come with only 2 speed settings (high and low). When it comes to managing plants, two settings are insufficient.

At a low setting, the humidity may be too low for the plant. In the same way, at high settings, it may be too high for the plant.

Humidifiers with at least 3 settings are ideal for plants. We have some humidifiers reviewed here that have got 3-speed mist output settings.

Types of Plant Humidifiers

Types of Plant Humidifiers

Just like we have previously stated, there are 4 types of humidifiers. So in this section, you will learn about them and know which is best to buy for plants.

Warm Mist Humidifier

This type of humidifier warms the water in the tank and then releases it into the atmosphere as warm vapor. This is the common type of humidifier you will often see.

Cool Mist Humidifier

This type of humidifies often comes with filters that remove impurities and dirt from the water. It releases a cool mist into the air.

Compared to the warm mist humidifiers, they use less electricity.

Evaporative Humidifier

This humidifier uses airflow to create vapor. It works by using a fan to pull air from an inlet and then blows it over a wet wick. The water from the wet wick is blown by the pressure from the fan, and it is released into the surrounding as mist.

Ultrasonic Humidifier

Ultrasonic Humidifiers are the most common types you will find out there. It uses ultrasonic vibrations to steam water in the tank, thus creating extra-fine droplets. This is further expelled into the air.

One of the major advantages is that they are quieter than the rest. A majority of them do not use filters. However, they are costly than other humidifiers.

All of the above-mentioned types of humidifiers will give your plant the best environment to grow healthy at all seasons. But the Warm Mist Humidifier and ultrasonic humidifiers will be the best choice.

Disadvantages of Plant Humidifiers

Just as humidifiers are important for plants, there are also some disadvantages you should take note of when using them.

It encourages the growth of bacteria

Bacteria and fungi breed well in a moist environment. Humidifiers, if not cleaned often, can provide a medium for the growth of bacteria and fungi. When they are released into the atmosphere and comes in contact with the plants, it causes diseases.

Unpleasant noise

Some humidifiers are noisy during operation. If you get a noisy one, it can interfere with your sleep. It is also not ideal for homes where there are babies or toddlers. However, people do get used to it and adapt pretty quickly.

It adds more chores to the house

Humidifiers create a conducive environment for you and your plants. But this doesn’t come without a cost. It adds more chores to the house because to continue enjoying the values it offers; you must devote time to cleaning it as often as it requires.

The production of excess moisture

The ideal humidity for indoors should not exceed 60%, except for some special cases where special plants may require a high level of humidity.

For humidifiers with poor speed control, excess moisture is experienced, which is disadvantageous. Excess humidity creates room for spore germination and successful infection.

A humidifier with a humidistat can, however, help counter this.

Collection and accumulation of white dust

When you use hard water or water that contains minerals, the humidifier will deposit them as white residues. This is deposited on the plants and blocks the pores used for photosynthesis and breathing. This can endanger the health of the plant.

Cleaning the plant leaves regularly, and using distilled water will avoid this effect.

How to Use a Humidifier

Best Humidifier For Plants

  • Humidifiers are built differently. Even if they have a similar method of operation, it is important to always first read the user manual.
  • Carefully open the humidifier to get access to the tank and fill it up with water to the recommended level. As we have stated before, we recommended using distilled water.
  • If you are using one that has filters, then ensure that the filters are in place.
  • Lock back the tank to position and place it in the appropriate position where it can be evenly distributed across the room.
  • Connect the power cord to a power outlet and switch on. Use the appropriate settings, depending on how much humidity you intend to achieve.
  • It is ideal to place the humidifier close to the plant because the mist will be more concentrated in the area around the humidifier.
  • You should also place the humidifier 6 – 12 inches from the wall, cotton, artworks, or anything that may absorb moisture.

How to Maintain Your Plant Humidifier

If you want your humidifier to last long, then maintenance is non-negotiable. The following are ways to maintain it.

  • Ensure to always wash and clean the storage tank as often as possible to avoid the build-up of bacteria and fungi
  • If the humidifier uses filters, always make sure to change them at most every 3 months or as soon as you notice clogging of the filters
  • If your humidifier doesn’t have an auto shut-off feature, always make sure the tank doesn’t run out of water
  • Since you will be working with water always, take precautions not to allow water to get in contact with the electrical compartment.

Plant Humidifier Frequently Asked Question

When should I use a humidifier for my plants?

Humidifiers should be used on your plants at the beginning of the winter season when the humidity and temperature drops. However, not all plants should be misted. Plants with hairy or velvety leaves are not ideal to be used with humidifiers

Do humidifiers cause mold?

Using humidifies at a very high-level setting can cause mold and improve the breeding condition of bacteria and fungi. This can further lead to allergies. We advise you to always have control over the level of humidity you allow with these units.

Should I use a cool or warm humidifier?

During winter, the atmospheric temperature is low. So the purpose of a humidifier is to increase the temperature and vapor level. Hence, it makes sense to use a warm humidifier.

Are humidifiers bad for the lungs?

Generally, humidifiers aren’t a bad idea. But some persons report having allergies when using them. If your plant house is separated from where you live, this will not be a problem since you don’t live with it.

However, most of these lung allergies are a result of uncontrolled humidity and the growth of bacteria within a dirty humidifier.

Conclusion

Plants grow healthy in a good environment where the humidity is favorable. Humidifiers are necessary for improving this during harsh weather conditions.

Having gone through our best humidifier for plant guide, you should be able to decide for yourself if you need one.

Every product reviewed here will be worth your time and money. However, it is necessary to go through our buyer’s guide again to enable you to decide which one is better for you.
