In this buyer’s guide, we’ll discuss the key features to consider for choosing the best humidifier for a 5×5 grow tent.

Size: What size is perfect for 5×5 grow tents?

Humidifiers are sized differently for different spaces, so you should choose one that fits the size of your grow room.

A humidifier with a capacity of around 2 gallons is ideal for a 5×5 grow tent. This will ensure that the humidifier can effectively add humidity to the entire grow tent.

Keep in mind that the size of the humidifier will also depend on the number of plants you have in your grow tent.

Noise level: What should be the highest level of noise for humidifiers?

Noise level is another important factor to consider. You’ll likely have the humidifier running for extended periods.

Therefore, you’ll want to choose one that operates quietly, so it doesn’t disrupt your day. Look for humidifiers that have noise levels below 40 dB.

Type of Humidifier: which type is the best?

When it comes to types of humidifiers, ultrasonic humidifiers are a great choice for growing tents. They are very efficient and easy to use but expensive. They break water into very fine droplets and then release them into the air as a cool mist, increasing the humidity.

Moreover, there are other types of humidifiers, such as-

  • Evaporative: These types come with a blower fan and humidity measurement features. However, they get noisier with time
  • Impeller: These types come with a disc that rotates and puts water into a diffuser. These are the least expensive options. However, they can be noisy from the word go, and the servicing can be tricky.

Mist Temperature: Which one do I need, cool mist or warm mist?

This is another crucial aspect depending on your location. Your plants shall benefit from a cool mist humidifier to simulate their natural environment if you live in a warm place.

On the contrary, plants feel comfortable with a warm mist humidifier if the natural environment is cold.

However, ultrasonic humidifiers do just fine if the climate is temperate. Ultimately, the mist type doesn’t create a big difference in most cases.

Price: What is the ideal price range of a 5×5 grow tent?

Of course, price is always a factor to consider when making any purchase. While you want to find a humidifier that fits your budget, don’t compromise on quality.

Pay more attention to the price if you can’t differentiate between other features. The one with a better brand value or warranty period should be better reasoning to pay more.

By the way, the ideal price range is under $100 for a 5×5 grow tent humidifier.

  • Adjustable humidity settings: Look for humidifiers that can be adjusted between 40 – 70% humidity
  • Built-in humidistat: A humidistat helps maintain consistent humidity levels for improved air quality and comfort
  • Easy-to-clean parts: Molds and bacteria can easily inhabit a humidifier if they can’t be cleaned regularly
  • Replaceable filters: You should be able to swap the filters if they get worn out
  • A timer function is also a great feature to have
  • Portability: The humidifier should be mobile, and the water tank should be portable, as the refilling will be done frequently
  • Remote control, automatic shut-off, and a water level indicator are some additional features that you may want to look for


Let’s look at some of the frequently asked questions and their answers related to the best humidifier for a 5×5 grow tent

Q.  What type of humidifier is best for a grow tent?

Ans. Cool mist humidifiers are generally considered the best option. They can also keep the air cool while maintaining the right humidity for plants which can be crucial. In contrast, warm mist humidifiers provide additional heat. Heat-loving plants can benefit from this. Plants, budget, and home environment all affect your final choice.

Q.  How do I lower the humidity in my 5×5 grow tent?

Ans. Dehumidifiers pull moisture from the air and then cast it back into the room as dry air.  Vents and exhaust systems pull hot, humid air out of the grow tent and let fresh, dry air enter. It’s possible to lower humidity in a grow tent with either method. However, a dehumidifier is more convenient for 5×5 tents.

Q. Is a cool mist or warm mist humidifier better for plants?

Ans. A cool mist humidifier prevents mold and bacteria growth and doesn’t raise the temperature of the room. It can get really hot in a warm mist humidifier, and it may cause plants to dry out because of the heat. Cool mist humidifiers also cost less to operate and maintain.


Maintaining proper humidity is important to get the best out of the grow tents. It is equally important as heating the grow tent. Without proper humidity, plants can hardly flourish to their full potential.
