What is the Best Humidifier for Plants? The Top 10 List.

Picking the best humidifier for plants can be tricky.

Humidifiers specifically designed for plants are the most effective way to produce the right atmosphere for hours at a time. Because certain plants require a higher rate of humidity than the natural surroundings, the right humidifier can make a lasting difference in the longevity of an indoor ecosystem. Although they may seem the same, not all plant humidifiers work for every climate.

Why Indoor Water Vapor is Good For Plants

Leafy, sprawling, indoor tropical plants are likely found in rainforests. Because of looming canopies found in jungle atmospheres, moisture is collected organically. The right humidifier will create the specific amount of water vapor that is needed for indoor plant life.

In dry climates, even rainfall will not produce the amount of water vapor needed for accurate humidity. Epiphytes, also known as “air plants”, require water supply from a variety of sources other than just the ground. Without the proper humidity, many of these plants cannot survive even indoors.

How To Make The Most Out of a Plant Humidifier

Not all plants need to be misted on a regular basis. Knowing which kind of humidifier works for what type of plant should be considered before purchasing a mister.

Tropical plants do best with a light mist.

Plants with hairy leaves, however, may not need a humidifier at all. A portable humidifier is usually recommended for those who are just starting to grow indoor plants. If a humidifier isn’t necessary for one area, it can always be moved to the bedroom for a good night’s sleep.
