Effects of Humidity on Plants: What Does a Humidity Do For Plants?

In heated apartments and houses, the air in your home is often too dry: an atmosphere that is too dry can harm certain plants. If you see the leaves on your plantations turning yellow and falling too often, the air in your room may not be humid enough.

To correct this inconvenience, choose your air humidifier carefully. This device will allow you to humidify the leaves of your plants. Indeed, it directly hydrates the pores of the leaves rather than the roots in conventional watering. It allows them to invigorate and keep them longer.

Importance of Well-Balanced Humidity for Plants

Not all plants have the same needs. Some cope very well with dry environments, and others require near-tropical humidity. This is why it is advisable to group plants according to the ecosystem that suits them best.

To understand how to proceed, you will find many tips on the Internet for maintaining your plants. When the air is dry, one is tempted to water the plant abundantly. However, too much water at the base of the plant can cause the roots to rot.

To fight against evapotranspiration, it is, therefore, advisable to mist or humidifies the air. Some particularly appreciate misting, except Saintpaulia, carnivorous plants, begonias, or cyclamen. For the most sensitive plants, a humidifier is, therefore, a better investment than a fogger.

Buying Guide for the Best Humidifier For Plants

On the market, you may find many types of equipment based on different technologies. And so, at the time of purchase, you may ask yourself: which one is better?

Let's briefly see what it is to allow you to choose the solution that best suits your specific needs.

Types of Humidifier for Plants

Warm Mist Humidifier For Plants

This type of humidifier produces a powerful and warm mist that is both soothing and visible. The humidity that is generated is particularly suitable for contrasting the climatic conditions of the cold winter months.

The water inserted in the tank is gradually brought to a boil: in this way, the humidifier spreads clean and hot steam in the environment. This system also traps irritants in the air, helping you breathe better.

Cool Mist Humidifier For Plants

The cold humidifier is available in various shapes and sizes so that it can be easily integrated into small, medium, or large rooms. The humidity produced by this equipment is invisible to the naked eye.

The dry air that circulates in your home in winter is sucked into the system. The fresh moisture is expelled into the room and circulated by a fan. The filter traps pollutants, sediments, and impurities so that only clean and refreshing air is expelled. This humectant technology is best for those who live in particularly dry climates.

Ultrasonic Humidifier

Two of the distinguishing features of the ultrasonic models are low maintenance and extreme silence. The water inserted into the tank is vibrated at ultrasonic speeds. On the other hand, the transducer works to produce a cool mist that is pure and invigorating.

The pure and welcoming fog that can be seen and felt quickly envelops the environment in pleasant comfort.

Evaporative Humidifier

These humidifiers are cheap and compact enough, making them suitable for smaller rooms. This type of humidifier is ideal for taking to the office or in the garage. Like the hot humidifier, the vaporizer humidifier uses a boiling process that frees the water from pollutants and releases fresh, uncontaminated air.

The generated steam is relaxing and welcoming and makes you feel pleasantly at ease in any room of the house. Unlike hot models, vaporizers do not have a removable tank.

Size and Coverage Area

When you want to buy a humidifier, you will have to ask yourself concerns the size of the environment you want to humidify. Based on this, you will have to choose a humidifier for the home with adequate autonomy and humidification capacity.

The size of the tank of the humidifier will affect the autonomy. For example, a 4-liter tank should guarantee, at minimum emission, from 12 to 15 hours of the humidifier's operation.

The humidification capacity, i.e., the maximum amount of steam that a humidifier can emit, is measured in ml / h. Normally, for a room of less than or equal to 20 square meters, a 200 ml / h humidifier should suffice. Instead, a double capacity (400 ml / h ) is needed for spaces of 50-60sqm.

Timer

Models equipped with a timer allow you to set the ignition on at a preset time. So the room is at the right humidity when you get home.

But this convenience could pose a problem. Water that sits in the tank for many hours can generate microbes if the humidifier doesn't dry out thoroughly between uses.

Ease of Cleaning

The humidifiers must be cleaned and disinfected regularly. If the unit is not cleaned, bacteria and mold can easily grow on the humidifier's moist surface. In fact, it is scientifically proven that it takes only 48 hours to allow mold to form on any damp surface.

That is why the product must be easy to clean. Not only the body but also clean a humidifier filter regularly.

Level of Noise

This is a product to be used often and in environments where most of the time is spent. So, the noise can affect the purchase.

The advice is to focus on models that allow you to decide the emission level (and therefore of noise). The best plant humidifier has a noise level of less than 30 dB.

Some models also feature night mode, and therefore more silent.

Portability, Quick and Easy Use

A tabletop humidifier must be easy to move and clean. The tank must be able to fit easily under the water tap. Look for a model with intuitive controls and a display that clearly displays the humidity level and settings.

Setup & Maintenance

The level of maintenance of humidifier required is also an aspect that should not be overlooked. This, as explained above, depends above all on the type of humidifier that you choose. The hot ones will require more frequent maintenance. It is also necessary to pay attention to the evaporative humidifiers' filters (these must either be cleaned or replaced, depending on how much is declared by the manufacturers).

Common to all types of humidifiers is the need to wash the tank very frequently (with soap and water). It will help to avoid the formation of bacteria and molds.
