At A Glance
Vivosun’s dehumidifier for 5×5 grow tents has a lot to like. It is one of the smallest dehumidifier units for 5×5 grow tents, while still having a water tank that is large enough that you don’t have to empty it too often. It also has more than twice the coverage needed for a 5×5 grow tent.
Design
Vivosun’s dehumidifier for 5×5 grow tents sports a compact, utilitarian design. It comes with a centrally-located air outlet that helps it cover larger spaces with ease.
A built-in handle comes in very…handy…for when you need to move the unit around a space or re-position it to remove moisture from a particular spot more effectively.
The large, C-shaped LED panel up front lights up to let you know when the unit is running, and also flashes to notify you when the water tank needs to be emptied.
Capacity
The Vivisun unit has the most voluminous water tank of any dehumidifier on this list. It is rated to hold just over 1.3 liters of water, which means you don’t have to go through the hassle of emptying it all that often.
That large water tank is despite the petite dimensions, so you don’t sacrifice any compactness in the name of a larger water tank.
Coverage
Coverage is great for a dehumidifier of this size, and more than enough for a 5×5 grow tent. We were impressed by the coverage capabilities of this dehumidifier, as it offered consistent moisture removal throughout the space, even in a 5×5 grow tent housing more plants.
And if you want this dehumidifier to run double duty for both the grow tent and the living room, the 270 sq-ft coverage rating should have no problems managing that.
Speed
Adjustable power modes or fan speeds would have really put this dehumidifier over the top, but no such luck. That said, it does have a stellar moisture removal rating of around 400 ml per day. That’s on the high end for a unit of this size and we have loved how quickly it brought the humidity of a grow tent down to optimal levels.
Efficiency
In our testing, the Vivosun did register slightly higher power draw than some of the other dehumidifiers we tested. This is only natural, given how well it performs, and we aren’t too surprised.
Moreover, we don’t think anyone will experience more than a nominal increase in their power bill if they use this dehumidifier for their 5×5 grow tent regularly.
Drainage
Manually draining the tank is your only option. Once again, we wish smaller dehumidifiers like this one could also have continuous drainage built-in, but no such luck.
Furthermore, we found that the water tank on our test unit stuck a bit when we tried to pull it out. This is hardly ideal, but you probably won’t experience this problem.
Noise Levels
Noise levels are perfectly in line with, if not a bit lower than other dehumidifiers for 5×5 grow tents. We have no complaints as far as the noise levels are concerned, and highly recommend this dehumidifier for anyone running the secret grow op.
Special Features
There aren’t very many special features to speak of with this dehumidifier. At most, you could say that the reliable high performance is kind of a special feature, but that’s pretty it.
It does automatically turn off when the water tank is filled to capacity, but that’s an old trick that every dog in the dehumidifier world knows these days.
Who’s It For?
We think the Vivosun dehumidifier for 5×5 grow tents is for the person who needs a high performance, reliable dehumidifier unit. Because really, that’s all it is; nothing more, nothing less.
Pros
- One of the most compact dehumidifiers we’ve tested
- C-shaped LED lights up to let you know the unit is running
- Flashes red when the water tank needs to be emptied
- Ergonomic carry handle
- 1.3 liter water tank
- Can remove up to 400 ml of moisture per day
- Coverage rating of 270 sq-ft
- Only needs to be drained every 3 days or so
- Noise levels are in line with other units of this size
Cons
- Slightly higher power consumption than some other units we’ve tested

At A Glance
Seavon makes a fantastic budget-friendly dehumidifier for 5×5 grow tents. This inexpensive unit has performance figures comparable to our top pick, along with even better power efficiency, and a compact design that fits in any nook or cranny of your 5×5 grow tent.
Design
You won’t be blown away by the simple design of this dehumidifier for 5×5 grow tents. In fact, the look is a bit basic, but that’s not too big a deal when the unit is going to be in a grow tent the whole time.
You get a small water level indicator up front, which lets you check to see if the water tank needs emptying. A pair of tiny LED lights are your only indicator that the unit is running or that it is at capacity.
Speaking of, the water tank is pretty easy to take out, for when you need to clean or drain it.
Capacity
Capacity is decent, especially for a unit of this size. You don’t need the highest water tank capacity in a 5×5 grow tent anyway, so the 800 ml of space this unit offers is more than enough.
Coverage
Coverage is ample for 5×5 grow tents, and even larger spaces can be dehumidified easily. This unit is rated to cover just over 200 sq-ft of space, so you shouldn’t have any issues with inconsistent moisture removal or damp spots in the grow tent.
Speed
Once again, the speed with which this dehumidifier removes moisture from the air won’t set any world records. It can only manage about 350 ml of moisture removal per day. That’s neither the best, nor the worst we’ve ever seen.
Efficiency
But one undeniable benefit of a smaller, less performance-heavy dehumidifier is that it is also less power-hungry. And in that regard, the Seavon stays true to its nature, with one of the most efficient designs of any dehumidifier we’ve tested.
We did not notice any spikes in the power bill, so you need not be concerned about that.
Drainage
We weren’t expecting this 5×5 grow tent dehumidifier to have a continuous drainage feature, and it did not let us down! Your only option for draining the tank is manually removing and emptying it.
Noise Levels
You might think that such a small dehumidifier unit would make a great big racket trying to reduce the moisture level of a space. However, you would be wrong, as this dehumidifier keeps it nice and quiet, even when asked to work harder.
Special Features
There aren’t that many special features with this dehumidifier for 5×5 grow tents. That said, we think that the use of peltier technology deserves praise, since it gives you better performance, as well as lower energy consumption in the same package.
Who’s It For?
We think this is a great dehumidifier for the person who needs to remove moisture from smaller spaces like a 5×5 grow tent. The compact design makes it very easy to put just about anywhere you need to, while the performance has enough oomph to remove moisture effectively.
Pros
- Compact design
- Ideal for smaller grow tents
- 800 ml water tank
- Can remove 350 ml of water per day
- Covers up to 215 sq-ft of space
- Highly power efficient
- Imperceptible noise levels
- Peltier technology used
Cons
- No continuous draining

At A Glance
This is another Seavon dehumidifier for 5×5 grow tents that really caught our eye. It is only a hair larger than the last one, but offers even more effective moisture removal. As for the feature set, you get everything you could possibly need from a 5×5 grow tent dehumidifier.
Design
One area where this dehumidifier has everyone else beat is the design and aesthetics. It is made of high quality plastic for added durability, but the base is entirely taken up by the transparent water tank.
This makes for one hell of a cool look, and one we think the plants in your grow tent will also approve of.
Another benefit of the high quality plastic is that the whole tank is lightweight and compact. This makes placement in your 5×5 grow tent a breeze, and if you need to move it around the space, it is just as easy.
Portability is also helped along by the integrated grab handle.
The last design element that a lot of folks will appreciate is the multi-color LED lights on this dehumidifier. They may not serve much practical purpose in a 5×5 grow tent, but if you want to add a bit of ambiance to the operation, you have the option.
Capacity
The capacity of the water tank is a bit higher than the other Seavon unit on our list. It comes in at around 1 liter, which is perfect for 5×5 grow tents. You won’t have to empty this unit nearly as often as some of the others we’ve tested, which is certainly a plus.
Coverage
Coverage also gets a bump up compared to the other Seavon. It is designed to cover just over 270 sq-ft of space. And when removing moisture from a 5×5 grow tent, having all of that power in reserve means you get even better performance for smaller spaces.
Speed
This is easily one of the faster dehumidifiers for 5×5 grow tents that we’ve tested. It can remove as much as 450 ml of moisture from the air per day, and we were never left wanting for faster dehumidification.
One cool feature of this dehumidifier is that it has two different power modes for you to choose from. These are great for when you need to quickly remove moisture from your 5×5 grow tent, such as in the case of spilled water.
Efficiency
Because it’s such a small dehumidifier unit, it is also pretty power-efficient. It sips power and we never noticed unexpectedly high power bill, even with long-term use over a couple weeks and months.
Drainage
Manual drainage is the only way to empty the water tank on this dehumidifier. Once more, to any dehumidifier manufacturers reading this: Please include a continuous drainage option in your 5×5 grow tent dehumidifiers!
Noise Levels
We are happy to announce that this dehumidifier offers virtually noiseless operation. It never got much higher than a whisper, even when we used the high power mode. That makes this the perfect dehumidifier for the secret grow op!
Special Features
An automatic shutdown feature ensures there is no leakage or overflowing with this dehumidifier. It’s also really great for safeguarding the sensitive internal components against electrical damage.
And lastly, this dehumidifier has one of our absolute favorite features of all: a washable filter. This is really useful for a couple reasons. For one, you don’t have to buy replacements. Secondly, you can wash the filter as often as you want to avoid any buildup or mold development, both of which could be disastrous for your plants.
Who’s It For?
So, to sum up, the Seavon 5×5 grow tent dehumidifier is for the person who wants a solid unit that is more reliable than others, and also has a washable filter for easier maintenance and a more hygienic moisture removal experience.
