Best Grow Tent Dehumidifiers Reviewed & Buying Guide

Indoor grow rooms are portable tents with reflective inner walls that allow you to grow your plants in a controlled environment. After going through many brands, sizes, and shapes of tents, you finally select the ideal for your indoor space.

But is that all you need to grow your little seedlings? The answer is no! It is merely enough.

Vegetation in a closed and controlled environment leads to many issues that we gradually learn to handle. One of the most common is the level of humidity inside your grow tent.

Humidity can be a blessing but also a curse. While plants need humidity in their primitive growth stages, they require a lot less later in their lives. So how do we manage the humidity? This is where a dehumidifier comes in!

A dehumidifier is an electrical appliance that has come to make our plants survive the immense humidity. It removes excess moisture from the air making it less hospitable for microbes.

These devices run smoothly and efficiently to make your place a fresher and healthier place not only for your plants but for you too.

Grow Tent Dehumidifier Buyer Guide:

There are certain things that you need to consider before buying a dehumidifier for your grow tent. The following are the most critical factors you need to keep an eye out for a while making the final call.

1. Size and Capacity of the unit:

It is crucial to choose the right size of the dehumidifier. By size, we mean its capacity, the amount of moisture it eliminates from the air.

To select an ideal dehumidifier for your grow tent, you need to measure the square feet area your tent covers and the usual amount of humidity it has.

A dehumidifier that can easily eliminate 70 pints or less moisture from the air is sufficient enough to be used for residential purposes.

2. Quiet Operation:

You need a dehumidifier that silently does its work and is not annoying for you and your guests when it is working. So, opt for a device that has a whisper-quiet operation.

3. Efficiency:

Devices that are Energy Star certified reduce energy consumption. This means they remove as much moisture as a conventional model but uses 30% less energy. It saves you a couple of bucks.

4. Air Filters:


Air Filters are something you need to be looking out for. You need the ones that can be detached and washed. Air filters remove all the musty odors, dust, bacterial microbes and molds from the air.

If not washed from time to time, your plants can be susceptible to mold growth on their leaves and, ultimately, death. Moreover, clogged air filters make dehumidifiers noisy.

5. Mobility:

You need a dehumidifier with caster rolling wheels and handles to move from room to room easily.


Frequently Asked Questions:

How do I know my grow tent needs a dehumidifier?

If your grow tent has a musky scent and has water vapor accumulation on the inner walls, it is an indication that you need a dehumidifier. Grow tents are equipped with grow lights that provide your plants with artificial sunlight to make food and energy.

Since the inner walls are reflective, heat accumulates on the inside, increasing the humidity level inside the tent and stopping your plants from transpiring and taking up nutrients from the soil.

How do I eliminate the water collected by my bucket?

A dehumidifier is equipped with a water tank that accumulates all the water your dehumidifier has removed from the humid air. You have two options. One, you can drain the water after every few hours yourself. Two, you can buy a dehumidifier with a hose connected to a floor-drain that automatically empties out the water as soon as it hits its full capacity.

Do I need special features in my dehumidifier?

Special features include features like a touch panel, auto-restart, auto-defrost, and turbo modes. They will make it easier for you to manage your dehumidifier and cause you much less hassle.

If it is not too heavy for your pocket, then go for a dehumidifier with unique features.

Are expensive Dehumidifiers better than inexpensive ones?

Never judge a dehumidifier by its price. Many dehumidifiers with economical prices can prove to be more efficient and long-lasting than the pricey ones.

Your prime target while investing in this device should be the features that it embraces and if it is applicable for your grow tent and not the cost. Be mindful of your budget and choose the one that befits all your requirements.

Bottom Line:


Dehumidifiers are the heroes you are looking for when giving your grow tent plants a better chance at thriving. So do your research and choose wisely.

We hope the list we have complied with above has been resourceful for you and can better help you choose the one that benefits your grow tent’s requirements now. Good Luck with your venture!
