Best Humidifier For House Plants

As early as the 1970s, NASA highlighted the ability of indoor plants to purify the air and clean up water. Since then, a great deal of scientific research has confirmed this amazing faculty. Better yet, most of these studies have proved that certain species have beneficial effects both on our health and our psychological balance.

Indoor plants and Their Positive Effects

Ambient Improvement

Our interiors, even the coziest, are often invaded by multiple sources of hidden pollution. For example: bad odors, electromagnetic waves and toxic substances released by our appliances. We are surrounded by multiple small nuisances that end up damaging our well-being. Even so, some simple actions can effectively fight against this degradation of our quality of life. Certain categories of plants thus have particularly healthy and effective properties.

The electromagnetic waves issue is more and more crucial for many people suffering from insomnia, headaches and other uncomfortable little symptoms. Despite their effect being always visible immediately, succulents or plants like cacti absorb some of these bad waves, from microwaves, computers and mobile devices.

Air Quality Enhancement

Some plants have a well-known effect on air quality: the depolluting plants. These plants turn carbon dioxide into purified water vapor and release oxygen. For instance, Sansevieria is known for its effect on bad odors, such as the smell of tobacco, and is a popular add-on for lobbies. Likewise, Azaleas do a great job with smoke odor absorption. Other plants boast soothing and relaxing virtues. The most famous is undoubtedly aloe vera, which is recommended as a cure for stress and nervousness. Also, an Aloe vera, installed in an office or bedroom, improves sleep.

Decorative and Mood Boosting Effects

In addition to the physical benefits of plants, one can praise the psychological properties. Many studies have highlighted, without a doubt, the benefits of color and fragrance stimulation. And for good reason, plants are key points when it comes to interior decorating ideas. In particular, the cacti are very trendy. Easy to maintain, aesthetic and original, they are popular with both men and women.

Furthermore, Feng-Shui philosophy and plants share a distinct page. The arrangement of the plants, according to the round or rather square leaves, to the south or to the north of the room, according to the principles of this ancient art, makes it possible to exploit the best virtues. Note that certain plants have incredible input in this domain. To name a few: the Lotus, a symbol of wisdom, Narcissus as a token for good luck and fortune for the coming year, the Peony, a synonym to prosperity and abundance.

Decorative, depolluting, de-stressing, plants need special care in order to keep providing us with these perks. Especially in winter, houseplants suffer just as much as we from the air dryness and excessive indoor heating. Most indoor plants love the hot and humid tropical climate so when facing dry air, their leaves turn yellow and fall. Eventually, the plant dies.

Best Ways to Nourish House Plants in Winter and How Can A Humidifier for House Plants Help

In winter, houseplants do not tolerate well the dry air and the low humidity levels caused by central heating systems. To ensure the best conditions for their development we have gathered some useful tips.

Recreate Tropical Conditions

To clarify, the idea is to recreate a micro-climate adapted to your plants. Install each plant in a pot that provides a 5cm diameter of wiggle space. Fill this gap with moss or peat. Use, preferably, non-calcareous water to spray the foliage, moderately, morning and evening. This environment preserves a tropical habitat for your plants. However, avoid spraying plants with downy or very thin foliage. Stagnant water on the leaves facilitates fungal attacks.

Clay Pebbles

Natural and quite decorative, the clay pebbles look great in terrariums and provide extra functionality too. You can also install your plants on a tray covered with a layer of clay balls that you water constantly. In short, by evaporating the water, these pebbles provide an ideal atmosphere for the well-being of your plants.

Humidifier for House Plants

Clearly, using a humidifier is always a good method to provide the necessary humidity levels indoors. Your plants and you will enjoy it. It is pretty uncomfortable and unhealthy to live in a too dry environment and that is why such a gadget can save you from a lot of trouble. Check out below some of the best humidifiers for house plants.
