SEAVON Dehumidifier For
3×3 Grow Tents
BEST OVERALL
My First Impressions
I have to hand it to Seavon, they really went above and beyond with this dehumidifier. It’s more compact than most, making it a cinch to place in 3×3 grow tents, but don’t be fooled by its size. Its performance is top-tier, rivalling even larger dehumidifier units.
Design Aspects
The design team at Seavon has done a stellar job with this unit. It sports a unique aesthetic with the see-through water tank forming the entire base of the unit. An ingenious feature, as it allows you to easily spot any mold or other build-ups in the tank.
High-quality plastic has been used to keep the unit lightweight and the footprint minimal. The design and dimensions are ideally suited to smaller spaces, and the in-built handle only makes transportation easier.
And the cherry on top? The multi-color LEDs. Although not essential for a 3×3 grow tent, the option of RGB lighting is always a nice touch!
Capacity Details
Of course, with its compact size and lightweight build, the water tank is somewhat smaller. However, with a capacity of 1 liter, it’s more than sufficient for a 3×3 grow tent, and I never felt burdened with having to empty the tank frequently.
Coverage Capacity
This dehumidifier provides way more coverage than you’d need for a 3×3 grow tent. It’s rated to cover around 270 sq-ft of space, which leaves a lot of power and performance in reserve.
I’ve found that high-performance dehumidifiers operating at lower settings tend to work better than less capable units pushed to their limits, so this is a win-win.
Speed Efficiency
This dehumidifier’s moisture removal speed is perfectly on par with other units of this size. It quickly tackles even the most humid of spaces, outperforming most of its competitors.
At its peak, it can remove around 450 ml of water from its surroundings per day, which is more than ample for a 3×3 grow tent.
The inclusion of power modes is a welcome feature, allowing you to tailor the dehumidification to your exact needs.
Energy Efficiency
If you’re operating a 3×3 grow tent, you’re probably working within a specific budget. The good news is, the Seavon is an efficient little dehumidifier. It doesn’t gulp down power, and I noticed only a negligible increase in my electricity bill. If you’re looking to avoid sky-high power bills for your 3×3 grow tent operation, this unit is worth considering.
Drainage System
Drainage on this dehumidifier is managed manually. Unfortunately, there’s no option for continuous drainage.
But, don’t fret, in a small space like a 3×3 grow tent, this dehumidifier’s generous water tank takes a while to fill up. Even in highly humid areas, you won’t need to empty the tank too frequently.
Moreover, the ergonomically designed water tank makes draining a breeze when it is required.
Noise Levels
If your little… tomatoes… in your 3×3 grow tent need complete silence to thrive, this is the dehumidifier for you. Even on the high power mode, it emits nothing more than a gentle hum.
A quiet dehumidifier is crucial if you don’t want any unwarranted attention on your… tomato growing operation.
Special Features
This unit boasts a smart water level sensor integrated into the water tank that enables it to automatically power down when the tank is full.
And the icing on the cake? This dehumidifier for 3×3 grow tents features a washable filter, one of my favorite features. Washable filters are preferred for 3×3 grow tents as they can be cleaned regularly, helping to prevent mold and the buildup of contaminants that could damage your… tomatoes.

Pohl Schmitt Dehumidifier For 3×3 Grow Tents
BEST BUDGET
My First Impressions
Pohl Schmitt’s dehumidifier for 3×3 grow tents is another solid choice. It might not match up to the Seavon completely, but it’s not too far off either. Given that it comes at a substantially lower price than its competitors, it’s hard not to be impressed!
Design Elements
Now, you shouldn’t be expecting any award-winning designs with this budget-friendly 3×3 grow tent dehumidifier. Truth be told, it’s not made with the highest quality plastic, and the only LED lights you’ll find are small indicators informing you if the unit is running or if the tank needs emptying.
But the true charm of this dehumidifier lies in its ultra-lightweight and compact nature. Plus, it does come with a slightly tinted see-through tank that helps you detect any mold growth sooner rather than later.
Capacity Insights
The water capacity is about half of the Seavon, clocking in at around 500 ml. Yes, it’s less than our top pick, but it’s still quite adequate for a small space like a 3×3 grow tent. Just be ready to empty the tank a bit more frequently than you would with larger units.
Coverage Range
Don’t be fooled by the small tank; the coverage rating is impressively high for a unit of this size. It’s rated to cover around 200 sq-ft of space, meaning you can anticipate consistent moisture removal even from larger areas.
Performance Speed
The daily moisture removal capacity, as quoted by the manufacturer, is 10 ounces. Once again, this is more than sufficient for a 3×3 grow tent. The budget-friendly price means you’re really getting an excellent bang for your buck in terms of performance.
Energy Efficiency
The power consumption of this dehumidifier is so low it could be less than that of a lightbulb. I saw almost no noticeable change in my power bill, even in extremely high humidity conditions.
Drainage System
Manual drainage is the only available option for emptying the tank. I always appreciate continuous drainage, but including it in this budget-friendly dehumidifier for 3×3 grow tents would’ve been too good to be true.
Noise Levels
I was pleasantly surprised to find that the Peltier setup in this dehumidifier operates almost silently under normal conditions. Even when pushed to its limit, the noise level barely goes above a whisper.
Special Features
This dehumidifier is not exactly brimming with high-tech features. It does offer an auto-shutdown feature that activates when the tank is full, which is a handy safety measure.
Other than that, the real specialty of this dehumidifier lies in its reliable performance.
Who’s This For?
If you’re someone who values frugality and is on the hunt for an affordable dehumidifier for your 3×3 grow tent, look no further than Pohl Schmitt’s unit. It may not be the most stylish model on the market, but it certainly delivers impressive performance where it matters the most.

Gocheer Dehumidifier For 3×3 Grow Tents
BEST PREMIUM
My Personal Take
The Gocheer’s dehumidifier for 3×3 grow tents might lean towards the expensive side, but I believe it’s more than worth the price. It offers a larger water tank capacity, a couple of additional features, and extended coverage that allows you to use it practically anywhere in your home.
Design Aspects
The dehumidifier’s design is quite straightforward and uncomplicated. It’s a bit taller in stature, which might actually be a boon when trying to fit it into snug corners of your 3×3 grow tent.
It features three large, centrally-mounted LED indicator lights which make it significantly easier to discern whether the unit is operating or needs to be emptied with just a quick look.
The tank is visible from the back, improving your awareness of its status, while a small window upfront also proves useful for checking the water level at a quick glance.
Impressive Capacity
This dehumidifier’s capacity truly outshines the competition. It has the largest tank I’ve come across in any 3×3 grow tent dehumidifier, boasting a capacity of around 2000 ml.
The advantages of such a large tank are pretty obvious. For starters, you won’t find yourself having to empty the tank nearly as frequently as with other models.
Plus, no matter how humid a space might be, this dehumidifier has got it covered.
Coverage Scope
The elevated performance allows you to use this dehumidifier in larger areas. In fact, it’s rated to cover up to 680 sq-ft of space.
You might argue that’s excessive for a 3×3 grow tent. While I can see where you’re coming from, my experience shows that higher-performing dehumidifiers that operate under less stress tend to outlast less capable ones that need to work harder.
Plus, it gives you the flexibility to use this dehumidifier in larger spaces like bedrooms, living rooms, and even hallways.
Performance Speed
This is undoubtedly the fastest-acting dehumidifier I’ve tested in this comparison.
It’s rated to remove up to 1000 ml of water from the air per day, putting it in the same league as some of the highest-performing units I’ve ever tried out.
If I were to nitpick, I’d say this unit could’ve benefited from adjustable power settings, but that’s just my personal preference.
Energy Efficiency
The larger the dehumidifier, the more power it tends to draw – that’s pretty standard.
However, the Gocheer truly surprised me with its efficient energy consumption. It won’t beat the smaller units in terms of energy savings, but when compared to other dehumidifiers of its size, it’s surprisingly economical!
You can expect a slight bump in your electricity bill, but nothing to lose sleep over.
Drainage System
I feel that continuous drainage should have been an included feature at this price point, especially given that similar models offer it.
Due to the larger size and increased volume, manually emptying the tank can be a bit of a chore. However, given the lower moisture levels in a 3×3 grow tent, you’ll only need to do this every other day.
Noise Levels
If you’re considering using this high-performing dehumidifier while you sleep or in the living room when entertaining guests, rest assured that noise won’t be a concern.
Despite its powerful performance, it’s remarkably quiet in operation.
Special Features
Gocheer has equipped this dehumidifier with a significantly larger air outlet, resulting in noticeable differences in air circulation. It also boosts the unit’s efficiency in moisture removal from the air in your 3×3 grow tent.
The dehumidifier uses advanced semiconductor condensate technology for quicker dehumidification, improved efficiency, and reduced operating noise.
Furthermore, the dehumidifier comes with an auto-off feature that kicks in when the water tank is full, helping to prevent any leaks or overflow.
Ideal Users
I’d recommend this 3×3 grow tent dehumidifier to those who also plan on using the unit in larger spaces such as bedrooms, living rooms, and hallways. Plus, the enhanced performance ceiling ensures higher reliability and longevity, even when using this dehumidifier in smaller areas like a 3×3 grow tent.
Pros
- 2000 ml water tank
- Can cover upto 680 sq-ft of space
- Removes up to 1000 ml of moisture per day
- Easily accessible water tank
- See-through design lets you keep an eye out for any buildup
