Why Humidifiers for Greenhouse
A greenhouse is a structure designed to provide a controlled environment for plants to grow in. It typically consists of transparent walls and a roof that allows sunlight to enter, and it’s equipped with systems for temperature, ventilation, and humidity control.
A few reasons why you should use a humidifier in a greenhouse are:
- To maintain the optimal humidity levels that plants need to grow and thrive.
- The right environment helps plants to retain moisture and nutrients, prevent wilting, and promote healthy growth.
- Helps to deter pests and diseases.
Using a humidifier in your greenhouse also provides other benefits, such as:
- Improving air quality

Picking the Best Humidifier for Greenhouse
A greenhouse allows you to grow indoor plants even if the outside weather isn’t very optimal. For the plants to grow at the best possible rate, it is necessary to keep a good mist temperature. These are the factors that one should consider when choosing the best humidifiers for plants:
Type of Humidifier
Here’s what you need to know:
- The warm mist humidifier is the most common type. It basically heats up the water and turns it into water vapor. This causes the humidity level to increase in the area.
- On the other hand, an evaporative one creates water vapor with the help of airflow.
- An ultrasonic cool mist humidifier uses vibrations to produce water vapor. These produce the best quality mist.
Covered Area
Let’s check out the details on the area:
- If you have a small-medium area to cover then the best plant humidifier would be a small one.
- But if the area you live in is very dry and you have a large greenhouse, then it is best to invest in a large plant humidifier like AIRCARE MA1201.
Refill Type
Most of the best humidifiers for plants come with a refillable tank. It is great for normal use but if you have a large greenhouse, then it is best to choose one that has a direct connection to the water supply. In this case, you won’t need to refill the plant humidifier again.
Tank Capacity
Here are all the details on capacity:
- The tank size varies in all of the humidifiers and there is no particular size that is the best.
- If you have a small tank then it will require you to fill the humidifier frequently and have a shorter runtime.
It entirely depends upon your preference and whether or not, you’re fine with refilling each or prefer not to.

Why Do Greenhouse Plants Need Higher Humidity?
Plants evolve according to the environment they are present in. If the relative humidity in an area is high then the leaves of the plants don’t hold as much water.
This allows the plants to survive in areas with high humidity. There are also some plants that due to their weak roots can’t absorb a lot of groundwater.
Common Humidity Levels for Greenhouse
No two plants are the same and thus the humidity levels are different for all of them. Some common humidity levels for some plants are:
- Orchids – 40 to 70 percent.
- Ferns – 40 to 50 percent.
- Other plants – 40 to 60 percent.
Additional Highlights Why a Humidifier is Good for Plants?
These are some of the things that you should look forward to in a humidifier for plants:
1. Run Time
At the minimum, the runtime of the best plant humidifier should be around 12 hours. If you don’t want to refill it again then ideally, go for the one that has more than 24 hours of runtime.
2. Simple Design
You will need to use the humidifier regularly for plants, so choose one which is simplistic in design and function. It should be easy to maintain.
3. The Mist Temperature (Cool and Warm Mist Humidifier)
The health of the plants is not affected either by cool air or warmer air. But if the mist is hot, it purifies the water, thus making a better-quality mist.
One downside of these humidifiers for plants is that they use a bit more electricity. A cool one doesn’t need a lot of maintenance and also consumes less electricity.
Alternative Ways to Humidify Plants
A humidifier is not the only way to humidify plants. These are a few other methods that can also be used:
1. Keep Plants in the Bathroom
The bathroom is the most humid place in everyone’s house. So, it is a good idea to place some of your plants in there. In this way, you won’t be able to show off your plants but it will surely keep them humid.
2. Send Them for a Shower
Another way is to shower your plants. It is a good technique as it cleans the plants and also freshens them up. Make sure to use gentle pressure and avoid any damage to the plants.
3. Use Plant Watering Globes
Plant watering globes are a convenient and easy way to keep plants watered. They work by slowly releasing water into the soil, which helps to prevent overwatering and underwatering. With the help of plant watering globes, plants stay hydrated even if you’re away for an extended period of time.
4. Make a Moisture Tray
If putting all of the plants in one tray isn’t an issue then you can make a moisture tray. It is a good way to provide extra moisture to the plants. Before adding water, make sure to suspend the plants over pebbles to avoid any stink and rot.
5. Use a Diffuser
A diffuser is yet another great way to increase moisture levels. If you have a few plants then using a diffuser is the best option. However, in this way, the water evaporates a bit slower than in a humidifier.

So, after going through all of the humidifiers, the one that stands out as the best one is the Elechomes SH8830. Here are 8 reasons why you should choose it:
- OVERTAKE YOUR EXPECTATION: SH8830...
- SMART AUTO MODE & NEAR-SILENT SLEEP...
