What Is Humidity?

Before you are up to buy a humidifier for your plants, you have to know what humidity is. When you will know about it properly, only then you can specify which plants need a lower or higher level of humidity. For the true growth of the plants, it is important to know.

Basically, humidity is simply the amount of vaporized water remaining in the atmosphere at that very specific place and time. Humidity is classified into two types those are relative humidity and absolute humidity. The absolute humidity indicates the amount of actual water vapor present in a cubic meter of atmosphere.

However, the relative humidity indicates the amount of vaporized water present in the air relative to how much water vapor it actually can hold at a certain time, place, and temperature. In a place of high temperature, the atmosphere can hold more vaporized water.

Thus, in the desert, we find hot air and lower humidity and in the arctic area, we find available water, cool air yet lower humidity. So, simply a warmer atmosphere will evaporate the water faster and consequently, it will cause high humidity and vice-versa in the case of comparatively less warm air.

Benefits of Plant Humidifier: Why Humidity Is Essential for Plants?

Like the human body, a plant’s body also goes through all kinds of physical metabolism. We all know that plant’s leaves inhale carbon dioxide to produce its own food. Through the making of their food, the plant leaf pores are expanded to absorb the carbon dioxide and the moment one pore is expanded the water remaining on that pore leaves the place vaporized into the atmosphere.

As a result, when the environment is too dry for the plants, they drop moisture fast and rapidly. When the leaves of the plants lose water quickly soon, it exceeds the root absorbing rate. When it happens the plant starts to wilt for the lack of water.

However, different plants demand different levels of humidity. The succulent plants tend to hold a great deal of water in their leave pores. It is because they have a root system that is robust. Again, the epiphyte plants are likely to be dependent on the atmospheric humidity. They barely absorb water from the ground.

Most of the indoor plants require a humidity of 40 to 60 percent. On the other hand, orchid and ferns demand 40-70% and 40-50% of humidity from the environment. The specific humidity is not possible to control unless you have a plant humidifier. So, a plant humidifier is always the right choice.

When Should I Use a Humidifier for My Plants?

A humidifier is needed when the temperature is too high. Turn on the humidifier in the morning and let the humidifier does its work until noon. Throughout this time, the sun creates a high temperature. Hence, the humidifier will create much humidity.

The produced humidity hopefully will last long throughout the day for the plants. Again, having a humidity gauge will help you more in this case. It will let you know about the humidity percentage in the air at that time.

When you get to know about the atmospheric humidity, it is easier to decide if the humidifier should keep running or not. If you find the humidity low in the atmosphere, let the humidifier operate for some more time to bring the humidity level up.

Again, know first what indoor plants are you nurturing in your room and what humidity level do they require. Only then, level up the humidity according to the plants’ requirement. But when the sun goes down, shut off your humidifier as well.

If you turn on the humidifier even when there is no sunlight, the mist from the humidifier will take place on the plant-soil or its leaves. This can cause multiple fatal diseases to the plants.

Things to Consider when Buying a Plant Humidifier

Room size: Before you are out in the market to buy a humidifier know about the room size where you are going to keep it. There are several humidifiers accurate for larger rooms and other for medium-sized rooms. If you buy a smaller humidifier for your larger room then it certainly won’t work.

And again, if you buy a larger humidifier for your smaller room then that will create up to 50-60% humidity in the air which can cause harm to the plants.

Tank capacity: Tank capacity is the most important thing to see in a humidifier. If the tank holds more than one gallon of water then it will serve for quite a long time. So, you don’t have to refill the tank frequently.

Operation time: Along with the tank capacity you have to know the machine’s running time. It should have the capability of operating a straight twelve hours minimum. Humidifiers that run more than this time should be considered first.

Whisper quiet running: It is another important feature to look for. The humidifier should not produce noise that is not ignorable while the humidification occurs. An ultrasonic plant humidifier is always suggested for this purpose.

Safe and protected design: An electric device should always be constructed maintaining safe and protected features. Focus on the machine material, its functionality, plugs, and original. If the humidifier is made of poor quality material it may cause several dangerous accidents.

An automatic shutoff feature should be added so that when the water inside the tank runs out the device automatically stops saving the plants and the family members.

Filters: Some humidifiers come including filter feature and some don’t. The filter featured humidifiers are more efficient yet the filters need to be changed after a certain amount of use. The humidifiers without filters are also the upgraded versions. They also work efficiently and there is no need for changing the filters again and again.

Humidifier types: There are cool mist humidifiers and warm mist humidifiers available in the market. And some special featured humidifiers also come with both the features. According to the users’ convenience, the humidifiers allow cool mist or warm mist.

Easy maintenance and cleaning: The plant humidifiers tend to be dirty easily. Hence, cleaning is required now and then. So, the cleaning of the best plant humidifiers should be easy.

So, these are the points you should keep in head to buy the best model of plant humidifier.

What Kind of Humidifier Is Best for Plants?

Cool mist Humidifier: These humidifiers release cool mists in the air. In this process, the machines catch different minerals and impurities in their filters.

Warm mist Humidifier: These humidifiers create gentle and warm mists heating the water throughout the system.

Evaporative Humidifier: Creating airflow this humidifier produces mist. In this specific process, a piece of cloth is needed and it gets soaked in the process. The process is quite a mess.

Ultrasonic Humidifier: With some of the built-in features the ultrasonic plant humidifiers offer both the warm and cool mists producing an ultrasonic frequency.

Now, the question is asked, what kind of humidifier is the best for plants?

Well, a cool mist plant humidifier is always perfect for your plants. But if you stay in a place where your plants do not get enough temperature for its thriving, then you better look for a warm mist humidifier.  Yet, both the type of humidifiers offers different advantages.

Like the warm mist humidifier boils the water inside the tank, it prevents all kinds of mold growth and bacteria. On the other hand, the cool mist humidifier keeps the water inside the tank at room temperature.

Hence, an ultrasonic plant humidifier does it all. It will offer you both the cool and warm mist your plant might need. The ultrasonic humidifier will require electricity and it has all the designs and features building in a high-quality method.

Maintaining Plant Humidifiers

For better performance and skillful efficiency, the maintenance of your humidifier is a must-do thing. These are some precautions you should be taking to have years of trouble-free service from your device. So, to make the humidifier highly durable maintain it in the following way.

First of all, know what type of water the tank of the humidifier requires. Using tap water is not suggested at all by the sellers. They suggest filling the humidifier tank with demineralized or distilled water. Water containing minerals can produce white dust while evaporating.

Resulting in the cling deposited in the bottom, it becomes hard to clean it off properly. Consequently, bacteria grow in that place fast. Hence, distilled water is used as it contains lower minerals.

Normally, a humidifier does not require frequent cleaning. Cleaning it once in every week is alright. Cleaning the tank of the humidifier is the most important and challenging task. Many humidifiers come with a congested feature.

Hence, it becomes tough to clean the tank. But many spacious ones come with a wider opening of the tank so that one can clean up the tank thoroughly getting his hand inside the tank. Make sure to keep a cloth at the bottom of the machine while cleaning to resist dripping of water.

How to Create Humidity for Outdoor Plants?

It is possible to create humidity for outdoor plants. But for that, you have to follow some rules so that the humidifier works well on the subject.

Plants should be planted in groups: It is the first and foremost rule to follow. Grouping of the plants will allow them to create an accurate moisture efficiency system. Every time a plant will release moisture from its leaves the other plant close to it will absorb the moisture. This is the way the system should be.

Smaller ones should be planted next to the taller plants: If you follow this idea, the transfer of the moisture among the plants will be more precise and effective. The dripping of water from the taller plants to the smaller ones provides a good chain of moisture-transferring.

Using little containers: For the moisture retention in the soil, the plants should be placed on the smaller jars. The smaller containers will retain more soil and the soil will retain more moisture in it. This is considered the absolute way.

Choose the best plant humidifier: Whatever the fact, you will always need the best humidifier for the nurturing of the outdoor plants. A long runtime humidifier will do a lot in this case.
