If you live in a dry environment and you keep your house at a comfortable temperature year-round, your house is probably also very dry. Living in an environment that is too dry can cause several health problems, the least of which are dry skin and dry sinuses.

It can also cause irritation in your mucus membranes, including your respiratory tract. In order to keep the humidity high enough to prevent such problems, you can use a forced air humidifier. If you’re an experienced grower, you already know that there are several materials you can use to create one.

However, if you’re new to growing, let’s start with the basics. Here, I will explain the important qualities you should look for when choosing the best plant humidifier you can.

Frequently Asked Questions (FAQ)

What type of humidifier is best for plants?

The plant humidifier should have a humidity setting that is adjustable. You will find that typical settings for a home humidifier are either on or off. The cheapest models do not even have a setting. However, you will find plenty of good models in the market that will most certainly have a setting. Humidifiers that have a humidity setting go further in controlling the humidity in your room.

Where should I put my humidifier for my plants?

First you need to place it where you can monitor it easily. You could also consider placing multiple units so they can work together to boost humidity. The next thing you need to consider is placement. Should the humidifier be placed on the floor or mount it to the wall?

While placing your humidifier on the floor will ensure that the mist flows freely throughout the room, it may decrease performance because the unit will be surrounded by the warm air it is adding. On the other hand, if you mount it to the wall, it can elevate the humidity levels in a confined area more efficiently, but it may take longer for the humidity to reach every corner of the room.

Mounting your humidifier on a table can be another option. However, if you place it on a table or shelf within a confined area, the mist may become stagnant without enough room to diffuse. In this case, a line of humidifiers may be the better option.

Should I buy a humidifier for my plants?

Whether it’s a decorative humidifier or a specialized plant humidifier, humidity that’s at an appropriate level will have a beneficial effect on the growth of your indoor plants. They can help prevent various plant problems such as brown leaf tips, too many dry spots on leaves, and wilting. In the long run, the right plant humidifier will stay in your house year round and will be a good investment.

Listed below are some of the best selling humidifying products for indoor plants.

Do plants like cool mist humidifier?

You can go with a cool mist/steam model (the more inexpensive option) or a warm mist model. The former is better suited for small grow tents and sheds. The latter can be used with uninsulated greenhouses; it’s a more expensive option, but it’s worth it if you have the extra budget, considering it helps in extending the growth season.

You can also find hybrid warm/cool models that can give you the best of both worlds.

Conclusion

Too often, people are striving to grow their plants, whether it’s for hobby or economic gain, but they don’t see the importance in keeping a balance in their indoor growing environment. This will result in less than ideal plant growth and cultivation.
