Is a humidifier good for plants?
If you live in a tropical area or a place with high green leaf content, you will notice the presence of warm or cool, humid air that will circulate the environment. Compared to a desert area with dry air and low humid conditions with almost no plants, plants need a good humidity level to thrive.
The whole point of using the best humidifier for plants is to recreate a humid environment in your home or garden so that they can thrive. Depending on the plans you are growing, some plants need a higher humidity level to grow well. But you should know that extremely high humidity levels can do more harm than good. So yes, humidifiers are suitable for plants when they are used to create the right environment.
Qualities to consider when picking the best plant humidifiers
- Grow Room size
Room size is a big consideration when you are buying a plant humidifier. So, depending on the room’s size, the humidifier you buy should efficiently serve the room’s needs and cover every square inch.
For a 300-square-foot apartment or less, you will need the best humidifier for a small grow room. But for a 350-square-foot to 450-square-foot room, you will need a medium-sized humidifier and, for any room size above 550 square feet, you will need a large-sized humidifier is best.
Your humidifier should also be able to keep the room humidity above 60% to encourage the plant’s growth. You should avoid too much moisture in a small grow room and too low humidity in a large place.
- Humidifier type
In choosing the best plant humidifiers, you should buy an evaporative or ultrasonic cool mist unit that is mobile and portable. While humidifiers can be beneficial to plants, the body of the humidifier also releases heat into the atmosphere that could affect the plant if the unit is placed too close. Keep in mind that the unit’s heat could cause dryness and possibly the death of the plant, so watch where you place the humidifier in relation to the plants in the room.
Portable humidifiers can be moved about quickly and situated in the most beneficial place near your plants. And remember that cool mist humidifiers use more energy than warm mist humidifiers.
- Noise level
If you sleep close to your grow room, you might want to consider how loud the machine is. Even some of the best humidifiers for tropical plants are noisy because they use fans that rotate when dispensing moisture into the atmosphere. Research and read some reviews to see how loud other users have found a humidifier before you buy it.
- Large water tank
Since the primary reason for using a humidifier is to make the atmosphere moist for the plants, you want a unit that can dispense mist at a higher rate than if you were using it for humans. Look for a product with a large water tank size, so you wouldn’t have to fill the tank too often when the water runs out.

How to mist Plants and increase the humidity
Even after finding the best humidifier for your plants, you might be confused about how to humidify a plant. To get the best results from your plants, follow these steps:
Always shower any outdoor plants from below when using the best humidifiers for plants. Misting below a plant will concentrate the water on the plant’s soil instead of just the leaves. When you are done misting, most of the water molecules will fall on the soil enabling the plant to absorb more moisture through the root without drowning in the excess water that follows heavy watering.
Also, when the leaves of a plant are subject to excess moisture from misting above, they will become more susceptible to viral and bacterial infections. The moisture on the foliage will create an environment where the spores are more likely to germinate, especially if there is poor air circulation.
It is important to raise the humidity levels of your house plant in the right proportions. A humidifier for a plant will help you accomplish this by increasing the humidity levels of the environment where the house plant is placed. A plant can draw enough moisture for its daily survival and growth in an environment with a safe humidity level.
When should I use a humidifier for my plants?
While a humidifier adds moisture to the air and benefits your plants, you should still know when and how to use it. For example, you should not mist your plants at night since it encourages diseases.
You should mist your plants in the morning, allowing them to dry out during the day. Water won’t evaporate at night due to a lack of sunlight, which causes the soil and surface of the plant’s leaves to retain too much moisture. And, when there is excessive water in the atmosphere, there is a better opportunity for disease-causing organisms to thrive.
How often should I mist my plants?
Before going on to answer this question, you should know that the whole idea isn’t about misting the plants but about ensuring that the humidity levels are always right for the proper growth of the plants. You should shower your plants every morning, providing enough water to live on throughout the day. And depending on the type of plant, you should mist the plants as much as possible throughout the day to maintain their healthy humidity levels.
For example, orchids generally need a humidity range between 40% and 70%, while ferns are comfortable between 40% and 50%. Most other plants fall somewhere between 40% and 60%. Knowing this, you should be able to figure out the proper humidity level for your plants and the appropriate misting rate you will need.
Where to place humidifier for plants
While a good humidifier for the plant is very useful for its health, placing it close to the plant is not good for it. When a humidifier sits too close to a plant, the fan can draw in moisture from the area it faces, removing it from the plant and leaving it too little to survive on.
On the other hand, when the humidifier is placed too far away, there is a good chance that the humidity produced will have less of an impact on the plant. Remember that a good position for the humidifier is about three to six feet away, which is not too close but not too far away. It also depends on the needs of the plant.
Can you use a diffuser as a humidifier for plants?
Since the main function of a diffuser is to mix essential oils with water and release them like a mist into the atmosphere, it does not serve the same function as a humidifier. However, a diffuser can add moisture to the air as it operates. Just remember that they are not what they are created for, and the moisture they provide is insufficient for the plant’s needs.
Compared to a humidifier, a diffuser holds minimal water and would need to be refilled every hour, depending on its size. It is not convenient for humidification purposes, and you should definitely purchase a separate humidifier for your plants instead.
How to create Humidity for outdoor plants
You should follow the steps below to create and maintain a safe humidity level for outdoor plants.
- Always plant in groups:
Grouping your plants will help them grow by allowing them to absorb moisture contents that other plants transpire. Basically, the moisture released by one plant is absorbed by another plant close to it, forming a closed moisture efficiency system.
Also, smaller plants should be placed on a tray filled with pebbles and water. Moss should then be placed on top to trap the moisture in the soil, making it ready and available for the plants.
- Growing plants in little jars or containers:
This has always been the right way to retain moisture in the soil for plants to use. We recommend you use container boxes with a lot of soil, which can retain water for the growing plants.
- Planting smaller plants next to the taller ones:
This has always been the right way to transfer moisture. When moisture forms on a taller plant, it drips off and falls onto the shorter ones that will use it.
- Get a suitable Humidifier:
Finally, and most importantly, you should purchase a humidifier. The humidifier will be responsible for increasing moisture content in the environment and frequently misting the plants. It is recommended to find a humidifier with long runtime.
