How does a dehumidifier work in a grow tent?

A dehumidifier is a device that removes moisture from the air. In a grow tent, the dehumidifier will help prevent mold from forming in your grow bags and other parts of the tent.

The process of removing moisture is called desiccation, and it happens naturally when water evaporates into the air. When you use a dehumidifier in your grow tent, it simply prevents any of that natural desiccation from happening.

As humidity levels in your tent rising and fall during the day, so does your dehumidifier’s ability to remove moisture from the air.

Choosing the Right Dehumidifier for Grow Tent


Dehumidifier sizes range from small to large. From 12 gallons to 40 gallons per day, dehumidifiers are available in many different sizes and styles. Some dehumidifiers have tanks that sit on top of the unit, and some have tanks that hang from the sides.

There are also floor-standing models, wall-mounted models, and portable models. For small 4×4 tents, a small dehumidifier of up to 8 gallons is more than enough.

Power Consumption

The power consumption of a dehumidifier depends on the size and type. For example, if you have a small grow tent that is 200 sq. ft., it may use less than a hundred watts of electricity. However, if you have a larger space, it may consume more than one thousand watts of electricity.

Tank Capacity

A dehumidifier’s tank size is the capacity of water it can hold. The bigger the tank, the better. The amount of water that you need to store depends on your climate and how much moisture the grow tent has to absorb.

The more moisture in a grow tent, the more often you’ll have to use this machine. For a 4 x 4 grow tent, a dehumidifier with 1500 to 2500 ml is more than sufficient.


Given that the majority of us have financial constraints, finding the ideal dehumidifier for grow tent within budget is crucial.

Depending on the size, capacity, and features of the dehumidifier, the price may vary significantly. Dehumidifiers for a 4 × 4 grow tent start at $60 and can go as high as you like. A high-end dehumidifier that will do the job can be purchased for under $100.

Ease of Use

The dehumidifier should have easy-to-use controls. You should be able to operate it without any difficulties, but it should not have limited functions. If it has a display, the text should be easy to read, and the controls should be easy to understand to operate the dehumidifier.


Last but not least, you have to look up the special features of a dehumidifier. The more the feature, the better it will be. First, if the dehumidifier has a removable tank, it would be very easy for you to clean and fill up the tank.

Second, the dehumidifier should be quiet, efficient, and portable. Next, if it has a washable filter, then it is the icing on the cake. On top of that, dehumidifiers with timers and multiple power levels are considered better than those with standard settings.
