Afloia Dehumidifier For 4×4 Grow Tent
BEST OVERALL
At A Glance
Afloia’s dehumidifier for 4×4 grow tents is pretty much the default. It uses peltier technology for better performance and improved efficiency. The water tank capacity is more than enough for 4×4 grow tents, and we don’t have very many complaints with this unit.
Design
You will need a smaller dehumidifier unit for 4×4 grow tents, since you need to maximize every bit of space. The Afloia’s design is one of the most compact we’ve tested, but it doesn’t sacrifice performance to achieve that look.
It only weighs around 1.9 lbs, so placement shouldn’t be too hard.
Speaking of the look, this dehumidifier has a unique ‘cat-ear’ design. Now the design doesn’t matter nearly as much in a grow tent dehumidifier, but Afloia claims that these ‘cat ears’ are specifically designed to improve air circulation.
And the cat ears are situated just above the large air outlet, so we’re inclined to believe the manufacturer!
One really cool design element is the integration of the power button right into the grill of the air outlet. This makes for a very clean look, and one that both your buds and your ‘buds’ will appreciate.
An LED light casts a soft glow over the whole unit, adding a bit of ambiance. We would have preferred the color of these lights to be customizable, but the most you get is an orange flash when the tank needs to be emptied.
Capacity
The water tank capacity is just a hair shy of 600 ml. That’s nothing groundbreaking, but for a 4×4 grow tent, it’s enough that you don’t have to empty the tank for a day or two at a time. It’s also one of the larger tanks in its class, so we can’t complain.
Coverage
You can expect consistent coverage of a space from this dehumidifier. It is rated to cover about 200 sq-ft of space, which is more than enough for a 4×4 grow tent. We never found the performance of this unit lacking, and we didn’t have to deal with pesky damp spots in the tent either.
Speed
If we were nitpicking, we’d say that this dehumidifier does take a bit longer to remove moisture from a space than some others. It’s actually fairly quick, and can remove up to 300 ml of moisture per day.
And to be fair, we found the speed setting to be quite convenient, since it only requires you to empty the tank once every two days or so. .
Efficiency
Afloia uses peltier technology for this dehumidifier. It is less power-hungry than traditional dehumidifier setups, which makes this dehumidifier cheaper to operate.
Our power bill confirms this, as it never registered any unexpected charges.
Drainage
It’s a small dehumidifier unit, so continuous drainage isn’t even in the cards. But as we mentioned, it doesn’t need to be drained that often, which is a plus.
When you do need to drain it though, the water tank mechanism is fairly easy to navigate. The drawer-style design makes it easier to take out, though the addition of a lid is an extra step compared to other units.
Noise Levels
Another huge benefit of the peltier technology used in this 4×4 grow tent dehumidifier is lower noise levels. We never noticed the unit get very loud, and generally, the sound didn’t get much higher than a low hum.
Special Features
You could say that the real special feature of this dehumidifier is the simplicity of its design. There’s only one button to worry about, the unit automatically shuts down when the tank fills up, and everything just works without any hassle.
Who’s It For?
We think the Afloia 4×4 grow tent dehumidifier is for the person who wants a high performance unit that isn’t too bulky or complicated.
Pros
- 600 ml water tank
- Only weighs 1.9 lbs
- Compact design
- Can cover up to 200 sq-ft of space
- Can remove upto 300 ml of moisture per day
- Cat-ear design and large air outlet improve air circulation
- LED light flashes orange when the water tank is full
- Easy-to-empty tank
- Only one button for controlling the unit
- Peltier technology used
- Less noise
- Better efficiency
Cons
- Might take slightly longer to remove moisture than some other units
Pohl Schmitt Dehumidifier For 4×4 Grow Tent
BEST BUDGET
At A Glance
This Pohl Schmitt dehumidifier is ideal for smaller spaces like 4×4 grow tents. It is one of the least expensive units we tested, but still offers effective moisture removal. It’s also fairly compact, making it easier to place in your grow tent.
Design
We weren’t exactly floored by the design of this dehumidifier for 4×4 grow tents. The plastic used for most of the build isn’t the highest quality, and you don’t get much by way of lighting. In fact, all this unit offers is tiny LEDs that let you know when it’s running or needs to be emptied.
But the most important takeaway is that this dehumidifier for 4×4 grow tents is insanely lightweight and easy to move around a space. Another plus point is that the water tank is fully see-through, so you can quickly notice any buildup or mold in the tank, both of which could spell disaster for your plants.
Capacity
Water tank capacity is actually pretty high for a dehumidifier of this size, and especially one of this price. It comes in at 500 ml, which is only slightly lower than our top pick.
And at almost half the price of our top pick, the value this dehumidifier offers is unmatched.
Coverage
It’s a similar story on the coverage side of things. The Pohl Schmitt dehumidifier for 4×4 grow tents matches our top pick’s 200 sq-ft coverage rating, and offers all the same benefits.
You get similarly consistent coverage, and the overall performance of this unit is beyond reproach.
Speed
The manufacturer says this dehumidifier for 4×4 grow tents can manage up to 300 ml of moisture removal per day. And while that is pretty good for a unit of this size, there are some disadvantages, compared to our top pick for example.
For one, it means you will have to empty the tank a bit more frequently. This is because the smaller water tank fills up a bit quicker than on our top pick.
But the fact remains that this is one of the cheapest dehumidifiers for 4×4 grow tents, so we’re willing to put up with a bit more.
Efficiency
Small dehumidifier= lower energy consumption. It’s as simple as that.
Even with extended usage, we never found this dehumidifier to consume too much power. Our electricity bill stayed pretty much unaffected, even when we ran the unt constantly.
Drainage
The budget price tag meant that we weren’t even expecting continuous drainage at all, and in that regard, this unit did not disappoint.
You will have to manually drain the tank every time. That said, the drainage is made a bit easier thanks to the straightforward water tank design.
Noise Levels
Pohl Schmitt employs a similar peltier technology setup as the Afloia dehumidifier, which makes this unit unbelievably quiet. Even when used in more demanding scenarios, the unit ran perfectly silent.
Special Features
Once again, you won’t get very many special features with this dehumidifier. It’ll automatically shut down when the tank is full, and that’s pretty much it.
Really, Pohl Schmitt chose to focus on the reliability and performance, rather than gimmicks. Still, some gimmicks would have been appreciated.
Who’s It For?
Pohl Schmitt’s 4×4 grow tent dehumidifier is for the cheapskates out there. We joke, but this budget-friendly dehumidifier for 4×4 grow tents is sure to be a hit with those of you who want to save costs on your grow op wherever possible.
Pros
- Can remove 10 ounces of moisture per day
- Covers up to 200 sq-ft of space
- 500 ml water tank
- Budget-friendly
- Very lightweight and compact
- Easily accessible water tank
- Peltier technology eliminates the need for a compressor
- Extremely quiet dehumidifier
- Auto shutdown feature for when the tank is full
Cons
- Not the most feature-rich dehumidifier
MADETEC Dehumidifier For 4×4 Grow Tent
BEST PREMIUM
At A Glance
Madetec’s dehumidifier for 4×4 grow tents is the answer to all our prayers. It has high performance, plenty of useful features, and, most importantly, it comes with continuous drainage.
Design
This dehumdiifier’s biggest drawback is actually how big it is. It is taller, wider, and generally has a larger footprint than any of the other units we tested. That makes it significantly harder to place in smaller spaces like 4×4 grow tents.
But that’s where the drawbacks end. This unit has a see-through tank, making it ideal for grow tents, where potential development of mold in the tank needs to be addressed as soon as possible.
And it’s not even as ungainly as we make it out to be. The large grab handle up top allows you to transport it from here to there pretty easily.
The one-button operation is backed up by 3 separate indicator lights that give you a lot of useful info at a glance.
Lo and behold! This dehumidifier comes with a drain hose as well. It isn’t the longest hose we’ve ever seen, but 5 feet is still plenty for setting up in a 4×4 grow tent.
Capacity
The larger size means this dehumidifier has a larger water tank. Specifically, it comes in at a full 2 liters. That’s almost 4 times higher than the next largest water tank on this list, so you can forget about the hassle of having to empty the tank too often.
Despite being a bit larger, the tank is still easy to remove for cleaning and emptying.
Coverage
Larger dehumidifier= better coverage. It’s as simple as that.
This Madetec unit is capable of covering up to 550 sq-ft of space, so you can be sure it’ll obliterate excess moisture in a space as small as a 4×4 grow tent.
Speed
The moisture removal capability of this dehumidifier is worthy of praise. It can remove as much as 1000 ml of water from the air per day, which is significantly higher than any other dehumidifier we’ve tested for this comparison.
Efficiency
Understandably, it does draw a bit more power than your average dehumidifier for 4×4 grow tents, but when you factor in the high level of performance you get with this model, it more than justifies it.
Drainage
Finally, we get the one feature that no other dehumidifier in this class was able to provide: a continuous drainage feature. The convenience of this feature for a 4×4 grow tent dehumidifier cannot be overstated.
It allows you to run the unit constantly without having to manually empty the tank every now and again. This is ideal for grow tents in extremely humid areas, where you might have to run the unit constantly to combat the moisture in the air.
Noise Levels
When met with a decibel meter, the Madetec did register slightly higher noise levels than some of our other contenders. However, we never noticed the unit get too loud or distracting, even when it was running at full blast in high humidity conditions.
Special Features
The unit will turn off automatically when it detects that the water tank is full.
It uses semiconductor refrigeration technology for enhanced performance and even better efficiency.
Not to mention, the larger size and higher coverage rating mean you can even use this dehumidifier in larger spaces like bedrooms, living rooms, and the like. That’s a feature no other 4×4 grow tent dehumidifier we tested can offer putting the Madetec in a class of its own.
Who’s It For?
The Madetec dehumidifier is for the person who needs a unit they can use for both their 4×4 grow tent and also the rest of their home. It has the performance to serve both roles effectively. And of course, the inclusion of continuous drainage just puts this dehumidifier over the top.
Pros
- 2000 ml water tank
- Can remove up to 1000 ml of moisture per day
- Covers up to 550 sq-ft of space
- Can be used in larger spaces as well
- Continuous drainage via drain hose
