How do you choose the right humidifier? 

1. Variety of humidifiers

There are varieties of humidifiers that you can buy, depending on their qualities and your needs, we have mentioned the best grow tent humidifiers in this article for you to select one. 

a. Ultrasonic humidifier

These humidifiers are the quiet ones. They work without any fan, the water is released into the air by the vibrating nebulizer. These humidifiers are a little costly as they perform advanced functions. 

b. Evaporative humidifier

In these humidifiers, a fan is fitted inside that blows the water droplets into the air by giving air onto the moisture-retentive wick. The humidifiers are automated and detect the amount of moisture available in the grow tent. The humidifiers are noisy but surely effective. 

c. Impeller humidifier

These humidifiers have rotating discs that transfer the water over the diffuser which transforms it into moisture and water vapors that are further transferred into the air. The humidifier is operated mechanically and is noisy. These humidifiers are pocket-friendly. 

2. Grow tent size

If you are buying the best grow tent humidifiers then there are certain things besides that too which you have to take care i.e the size of the tent is really important to consider while buying a humidifier, there are the best humidifiers for small grow tents, and large depending upon your requirements.

The humidifier’s efficiency in spreading moisture in that space is seen accordingly. The small grow tent will not have too many plants, for this space, the humidifiers you will need should cover 100 sq feet of space. While for the large rooms, you will need large humidifiers, the best would be a whole-house humidifier. 

3. Size of water tank

The water tank size is another characteristic you should consider while buying a humidifier. The humidifier, if large, has high durability and needs fewer refills. The water tank of 2-3 gallons will need to refill just one time a day while a one-gallon water tank will need water within a few hours like 12-16 hours. 

4. Replacement of filter

The filter replacement needs to be done in humidifiers to keep the air clean. Some humidifiers need replacement within a few weeks while others will not need much replacement. Keeping the filter clean is the secret to staying away from replacing headaches. 

5. Range of noise

Noise can be irritating sometimes. You should know what space you are going to install a humidifier in. If the room is not near your house, you can buy a noisy humidifier but if it’s near your home, the noisy humidifier will give you a head strain after some time. 

6. Cleaning the humidifier

A lot of impurities and mold growth can occur in humidifiers, so you need to clean them. The humidifiers that can be easily cleaned and taken apart are the ideal ones. 

7. Portability
