Let’s welcome the winner model of the list, the best grow room dehumidifier, the hOmeLabs HME020030N.
Remove moisture and Restore Freshness- that’s the tagline that hOmeLabs has for this beautiful dehumidifier. It doesn’t only take the humidity away but also keeps the air free of mold, mildew, and irritating odors.
If you plan to cultivate up to 50 plants in any large grow room setup, the 30 pints/day version will single-handedly take over the task to keep it dry. All you have to do is put it in a way that captures the whole airflow of the room.
It has got a good dehumidification capacity that doesn’t essentially require that it has to be super hard to control. In fact, all you have to do is to adjust the ideal moisture level. Once done, it will repeat itself for a cycle of 24 hours until the dehumidifier tank is fulfilled.
Wait, there is more to talk about dehumidification control.
The hOmeLabs HME020030N sports a touch control panel where features like defrost, restart, and turbo modes are embedded right in. Not overwhelming, but it can certainly be labeled as a super dehumidifier ahead of its time.
Worrying about safety issues? Well, the tank is able to shut off itself once the water tank is full. In case you’re out of time to empty up the tank yourself, there is a drain hose outlet that will keep the draining process going. No additional timer, no constant monitoring. From many home labs dehumidifier reviews, we’ve been over-certain about each of these safety concerns.
Isn’t it convenient for a busy grower?
One of the biggest eye-catching virtues of this model is, its compact design and beautiful aesthetics. The sleek clean look, compact footprint (15.2 x 10.2 x 19.7 inches only), and the soothing outfit- all are meant to be a show stopper. Therefore, you can use it as the dehumidifier for the living room, bedroom, and anywhere when it’s not being used in the grow room.
Talking about transporting it from the grow room to anywhere else, there are built-in castor wheels and handles that make the task easy. The overall weight is about 30 pounds. So, no hardship there as well.
Worrying about the compatibility of dehumidifier reservoir size for your large grow system or large grow tent? Well, the version of hOmeLabs HME020030N that we’ve picked up is of 30 pints/24 hours dehumidification capacity. It has other models – 50 pints and 70 pints. The last two are the best dehumidifier for 3000 sq ft and the best dehumidifier for 4500 sq ft consecutively or environments with particularly high humidity.
However, this product isn’t completely autonomous. What we mean is, to keep things tip-top, you’ve to clean up the tank once in a couple of weeks. Also, the filter is required to clean once a month. That being said, the cleaning frequency is still better than many of the typical models.
Summary line? hOmeLabs HME020030N is definitely one of the biggest bangs for bucks, and we’d happily recommend it to keep your grow room up for better yields.
- 30 pints/day capacity with 50-pint & 70-pint further models.
- Touch panel control with restart, auto shut off, and turbo mode.
- Removes moisture, odor, mildew, and mold from the air.
- Sleek and stylish dehumidification design with a minimal profile.

The runners up slot for the list was a close competition. But Frigidaire FFAD2233W1 earned it by every means. Being released for around a couple of years, this dehumidifier had held a solid position of popularity among growers.
Therefore, we’ll go through a detailed Frigidaire FFAD2233W1 review to determine whether it’s the right fit for you or not-
The Frigidaire FFAD2233W1 runs on a household 115V environment, and the power it consumes is quite less than even many popular models. So, it can be your way to save up some energy bills.
The dehumidifying capacity of this model is 22 pints in a span of 24 hours, and that’s perfect for large grow tents and grow rooms. No matter its aeroponics, hydroponics, or typical soil-based grow systems that should be more than sufficient. All of these environments may need different humidities but as long as it’s operating within its manual RH range of 35% to 85%, it’s the best kit you can even have for cooling and dehumidification.
Another good thing about this product is, it doesn’t just take the humidity away from your grow system, but also makes the air cleaner and purer. Its efficient dehumidification effect takes off the mold and mildew buildup in the moist air and gives it a fresh intake of pure air. In addition, it has got an antibacterial mesh filter to reduce the odor, bacteria, and other airborne particles right away.
So, you can say it’s a 2-in-1 dehumidifier and air purifier.
You can’t always keep an eye on this model to check whether the water tank is full, right? So there is a tank alert system that induces auto shut off once the water tank is full.
To make sure that you can transport it easily from place to place, there are a number of features included. First of all, there is a 6 ft long power cord that gives you a range of moving space. In case you want to hand-carry, there is a top handle, side handles and a caster wheel to move on. You can say, it’s one of the most portable models in the market that’s very easy to move.
The last factor to check is the price-quality ratio. Well, it’s definitely not the cheapest pick in the industry. But with so many features provided, you don’t expect it to be so, right? From a neutral point of view, it’s one of the best price-quality ratios that we’ve come across.
- Can take 22 pints of moisture in a day.
- 115 operating voltage, rated by Energy Star.
- Protects mold, mildew, odor, bacteria buildup.
- Comes with an anti-bacterial air mesh.
- Integrated top and side handle along with casters.

If we focus our radar on the dehumidifiers that are only meant to be for grow rooms, then this model from Vremi is the best dehumidifier for indoor growing. And we have got quite some evidence behind such claims.
We’ll break the specs of Vremi 30 pint energy star dehumidifier into bite-size chunks below –
First things first, it’s the dehumidifying and purifying job that it does. Well, you can say that it’s not just a dehumidifying device, but also an air purifier. Firstly, It can remove 4 gallons of humidity at a 30-pint rate, and that would be more than sufficient for a grow room up to 1000 square feet. Secondly, it can eliminate moisture, odor, and any other nasties from the air.
There is a turbo mode of this model that switches the fan speed from 129 CFM to 138 CFM. And guess what this boost can do? Well, let us answer on your behalf –
A rise in the CFM level of the appliance gives it a boost to make the air circulate faster. Therefore, the moisture, the odor, the unexpected micro-bacteria, mildew, dirt, allergens, dust, mold, etc. get terminated. All you will get is clean air.
There are many users (growers) who are literally hateful of the job of air filter removal and cleaning when it’s about dehumidifiers. But this one from Maniac is a pretty fine exception. It’s easy to take on and off, and you have to do that once a month only. If you use it less often, cleaning the filter once in a couple of months will also do.
Want to make multi-purpose use of it? Well, it will definitely let you do so. Even, to make your job of transporting it from one room to another, they’ve provided it with a wheel castor. The weight of this device is around 31 pounds, which is another plus point in terms of portability. All you have to do is set it at a suitable position and set the timer up.
The summary line is, the Vremi 30-pint Dehumidifier is a nicely built, efficient, portable dehumidifier that can also do air-purifying on your behalf.

Moving forward, it’s the water tank, and its the drainage system. With this model from Inofia, you’ll have a 1.8L water tank and a drainage system that works on its own. Although, it’s not the largest in the game, we think it’s good to go as the best 2-liter dehumidifier for grow systems.

Therefore, they’ve made it with an intelligent control panel, a time control system, and a single-press switch on and off features.
Among all these aspects of the control, we’d love to focus on the time controllability for a moment. You see, a little deviation from the dehumidifying process can lead to disaster for your plants.

Done with checking the products out? Here are some dehumidification basics for first time users-
What is a Dehumidifier?
Simply put- a dehumidifier is an electric or non-electric system that takes the humidity out of the air by drawing out the moisture. It works usually within a confined area like grow rooms, grow tents, basements, bedrooms, bathrooms, show boxes, and many more. The benefits of a dehumidifier are, therefore, an essential aspect of any sealed system.
The technology that is used in the dehumidifier collects moisture content from the air and converts them into plain water. Therefore, they are equipped with a water reservoir to hold what has been extracted from the air and this needs to be emptied on a regular basis.
Types of Grow Dehumidifier
The classification of grow dehumidifiers can be done from two points of view. The first one is based on the area that you’re able to work on, and the second one is the dehumidifying technology that it’s up to.
Here is the first perspective-
Dehumidifier for grow room:
They are with high dehumidifying capacity, and the power consumption is also more than other types. They are bulky in size, but a number of portable models are in there.
Dehumidifiers for grow tent:
These are quite smaller and lighter compared to the first type. They use almost the same technology but to a smaller degree. Therefore, they can cover up spaces of up to 300-500 square feet.
Dehumidifier for grow boxes:
They’re quite small, mostly non-electric type. They don’t require electric power and that’s sufficient to cover up small grow boxes, shoe boxes, cabinets, etc.
In the second kind of classification, here you go-
- Electric Dehumidifier: These are based on an electric formula to attain water contaminants from humid air. They run off 115V usually, and they can take out around 10-16 ounces of moisture in a day. For getting the most out of this type of model, you’ve to know how to use a dehumidifier of such sort.
- Non-electric Dehumidifier: These are rather passive dehumidifying systems that use silica gel layers to absorb water contaminants from the air. Induce a passive airflow with these models.
Buyer’s Guide
Hopefully, you’ve been going through all 11 of the best dehumidifiers for grow systems and made your shortlist already. But putting the right dehumidifier in a grow room will take further trimming down of the list.
To hone up even more, here is an extensive buyer’s guide for you-
The Rate of Dehumidifying
Of course, dehumidifier capacity calculation is the first thing to look up in a dehumidifier device. Most of the large-scale dehumidifiers can take up to 18-20oz of water containment in a day. In the case of smaller units, 8-12oz of moisture removal is expected. However, with increased dehumidifying ability, the power consumption raises up.
