Do you have indoor plants? Indoor plants are known to make people happy. They help improve our health and even the air as well. Like everyone else, you probably water on a regular basis thinking it’s all the water they need.
But do you know that a humidifier, especially specifically for plants, can help maintain that moisture level in plants? Even during the winter, where the air is so dry, the humidifier can help keep the plants in top shape. If you have any sort of sinus issues, it’ll help keep your sinuses clear. Now you know why plant humidifiers exist, and we’ve gotten your attention, read on to see some of the best plant humidifiers and some features to consider while deciding whether or not you want a plant humidifier.
Top 3 Picks
We chose this as our favorite because while it’s small, it’s 2 in 1 being a humidifier and diffuser. We also like the top fill design as well.
We love the Homech because it’s large enough to take care of a small living room but it’s also super quiet. The filters are easy to change too.
This humidifier is quiet, and it comes in different colors. We love how it has a nightlight as well.
Humidity and Plants
Believe it or not, the average home has very low humidity. So, for plants, they usually don’t get the moisture they need unless you water them. If you have tropical plants and you’re trying to keep them alive in a bone-dry environment, they won’t thrive as well even if you’ve put them in the sun.
Humidity levels as low as 50% are insufficient for these species, and others recommend humidity levels as high as 80%. In the winter months, hot pumps blast and blow heated, dry air around the whole house, in comparison, many homes are virtually bone dry. Humidity is usually common in these homes by 20 percent.
What plants need a lot of humidity?
The following plants really do need a lot of humidity if you are planning to get one for your house:
- Carnivorous Plants
- nerve plants
- prayer plants
- fiddle leaf figs
- air plants
- Most tropical plants
Now that you get the gist of who really needs the moisture, you should know how to care for them.
How to make sure the plants get high humidity
Grouping your plants
The mechanism by which plants emit moisture through their leaves is known as transpiration. By grouping plants, you will build a more humid microclimate in your growing environment, which would support all of the plants. It’s also a smart idea to hold plants with common humidity needs together. If aroids are your passion, for example, combine all of your aroids in one location where their faster transpiration rates can produce higher atmospheric humidity in the developing region.
Mist those plants
You probably already do, but you should mist the plants (watering) on a regular basis so that the plants don’t die.
Get a Humidifier
It’s why you’re reading this guide now. Humidifiers really do work for keeping plants thriving in a healthy environment.
If all else fails, use a terrarium
Consider going to terrariums if you are trying to keep plants alive and keep failing no matter what you do. A terrarium is a small, enclosed space with soil and a few small plants. The device is enclosed, so the plants absorb moisture, “exhale” it by transpiration, only for the moisture to collect on the terrarium walls and fall back into the rising media, much like the water cycle of nature. Terrariums are ideal for smaller plants that need more humidity and heat.
What are the symptoms of low humidity of plants?
It is actually hard to pinpoint the low symptoms because you could either be overwatering it or it has too much light. Obviously, you know that if you’re not doing enough, the leaves will start to look pale and start crumbling up. Then they turn brown. If new leaves do not look normal or start shivering up, you know then there is definitely a humidity problem that you’ll need to diagnose.
Types of Humidifiers for Plants
There are two types of humidifiers for plants that you should look for. They are Ultrasonic and Evaporative.
High frequency (ultrasonic) vibrations are used by ultrasonic humidifiers to allow the evaporation of water. The waves vibrate the water and produce fine gout. Usually, ultrasound humidifiers are a little bit higher than evaporative ones, have no changing filters and are louder. Due to the failure to heat water and ultrasonic transfer of water to nebulae, there is a lower chance of burns from spills. The disadvantage is that without heat that usually inhibits bacteria and mold formation, you periodically disinfect the device to avoid pollution.
These types of humidifiers use airflow to create mist. It then uses the fan to pull water over the wet wick. Evaporative humidifiers usually have filters, which you’ll have to change from time to time. It helps prevent the growth of bacteria and mold. They cost much less than the ultrasonic ones, but you’ll have to deal with the noise due to the fan.
What to look for in-plant humidifiers
You’ll want to understand humidity and plants before you spend money on a humidifier. Humidity means there’s ample moisture in the air. When it’s cold out, humidity decreases massively, and this is when you’ll want to consider a humidifier. They are relatively inexpensive to help keep your plants healthy. Here’s what you should consider:
A humidifier with a moisture output matching the size of your room is very important. If the output of your humidifier is less than the size of your bed, optimum moisture dispersion is unlikely. It is also useful to see where your humidifier would be located. It is safest for your humidifier to be at least 6 feet away from your plant, especially when you have a fan because the direct airflow will lead to the loss of moisture in your plants.
To prevent releasing too much or too little moisture, the amount of moisture released by your humidifier should balance the temperature of the room. Therefore, moisturizers are designed to adapt in accordance with the atmospheric air condition with mist production sensors. At least two settings are used with most humidifiers: low and heavy. However, there are three-speed devices used to monitor the dung performance a little more. Some models often report a relative percentage of humidity to better measure the environment’s moisture levels.
Many humidifiers are not created equal when it comes to noise levels. If you spend a lot of time in or around your grow room, you might look into a device with a low noise output. The fan used to drag air over the wicking component of evaporative humidifiers produces more noise than ultrasonic ones.
This isn’t a huge factor, but it’s still something to consider. The warmer mist tends to be pure because of evaporation. However, the cool mist, that you see in a lot of humidifiers, are more cost friendly, as they don’t need as much energy to run.
This you will need to consider, because a small tank, that’s meant for small rooms will typically emit less moisture. However, if you need something that can run for hours, you can get a bigger humidifier that has a much bigger tank without needing to turn off or refill as often.
Some of the larger ones require filter changes, so you’ll want to change it every 2-3 months to keep the humidifier in top shape.
