Best Dehumidifier For 4×4 Grow Tent: Reviews

Did you know that it is very important to have the right level of humidity in a grow room or grow tent for marijuana? Yes, that is right, weed seedlings, plant in their vegetative state, and pot plants in their flowering states all require different levels of air humidity, and they do need to kept fairly on point for the best, biggest, and most potent yields.

Now, heating, cooling, and ventilation will all affect the humidity level in your grow tent. One of the easiest ways to keep the humidity level at an ideal level in your grow room is to use a simple dehumidifier. However, what happens when you have a really small 4 x 4 grow tent with limited space? You will need a small yet efficient dehumidifier.

Choosing the right one for your cannabis grow tent can be difficult. This is what we are here to help with today, to find the best dehumidifier for 4×4 grow tents, and to teach you how to find the right one, as well as some other important facts and tips too.

What To Look For In A Dehumidifier For A Small Grow Tent

a Dehumidifier

Ok, you really do not want to go out and buy the first dehumidifier you see, because they are not all the same.

When purchasing a dehumidifier for your small 4 x 4 grow tent, here are the main considerations which you should always keep in mind;

1. Square Foot Coverage

The first thing to look out for here is how many square feet the dehumidifier in question is rated for. Now, a 4 x 4 foot grow tent contains 16 square feet.

In all reality, you won’t ever be able to purchase a dehumidifier that cannot handle this much space, so it should not be a huge concern.

2. Size

You do also want to look at the size of the product in question. A 4 x 4 grow rent is really small, so there is not much space to spare.

This means that getting a dehumidifier that is more than 1 foot wide or 1 foot long is out of the question.

However, when it comes to height, as long as the thing is not taller than your grow tent, you will be just fine.

3. Energy Use

Dehumidifiers are electric appliances and that means they cost electricity to run. Growing pot is already expensive enough, so being able to find a dehumidifier that is cheap to run in terms of energy use is a big deal.

On that same note, you should also aim for something that is fairly quiet, because nobody likes noisy appliances.

4. Water Tank Capacity

The next important thing to look for in a weed tent dehumidifier is that the water tank capacity is like. Simply put, you don’t want to have to empty the water reservoir on a daily basis.

Moreover, this will also have to do with how much water the dehumidifier can extract from the air on a daily basis. The smaller the reservoir and the faster the dehumidifier can pull water out of the air, the faster it will fill up.

Something to note here is that you need a small item for your small grow tent, which inherently means that the water reservoir is going to be small. It’s just something you will have to deal with.

On a side note, having a model that comes with an automatic shut off feature in the event that the tank fills up is a pretty big deal too.

5. Controls & User Friendliness

Some dehumidifiers only have an on/off function, which is fine if you have the time and tools to measure humidity and keep it in check.

However, the much better option here is to go with one where you can actually set the precise humidity level, so the dehumidifier will turn on and off on its own when needed.


10 Best Dehumidifiers For 4×4 Grow Tents: Reviews

Here we have what we think are the best dehumidifiers for a small grow tent, such as a 4 x 4 grow tent that has very limited space.

Do keep in mind that here we have chosen small units, as a 4 x 4 grow tent is not large at all, so any dehumidifier you put in it needs to be very small, compact, and space friendly.

1. hOmeLabs Small Space Dehumidifier

This is a great mini dehumidifier to get for a 4 x 4 grow tent. It comes in at a very small size, and it is truly mini, which means that you should be able to easily fit it into even the smallest of grow tents, such as a compact 4 x 4 grow tent.

The hOmeLabs Dehumidifier is an ideal dehumidifier for spaces up to 150 square feet, so it is more than large enough for a small grow tent such as this.

This item has a water tank capacity of 16 ounces or 500 ml, and it can extract up to 250 ml of moisture from the air daily. In other words, all things considered, even though it is a small item, it still has enough tank space so that it does not need to be emptied every single day.

It also has a full tank indicator and an auto shutoff feature, so when the water tank is full, the hOmeLabs Dehumidifier shuts off on its own. If you use it right, you will probably only need to empty it every 3 or 4 days.

What is also nice about this dehumidifier is that it is very quiet and energy friendly at the same time, both big benefits no doubt.

However, one big drawback to keep in mind here is that this item turns on or off, but does not allow you to set a precise humidity level, so this is something you will have to deal with on your own.


2. Ivation Thermo-Electric Intelligent Dehumidifier

Here we have another nice small dehumidifier that should fit into even the smallest of grow rooms with ease. It comes in at a super compact size, so it will not take up too much space that you would otherwise use for your plants.

The fact that the Ivation Dehumidifier is so small is also helpful because it is fairly energy friendly and won’t cost you big time in terms of your electricity bill. There is also the fact that it is fairly quiet so its noise won’t disturb you too much.

Keep in mind that the Ivation Dehumidifier is ideal for rooms up to 100 square feet, which is more than enough to suit a 4 x 4 grow tent. This thing does have a fairly decent sized water reservoir, considering the overall small size of it.

It can extract up to 25 ounces of water from the air on a daily basis, which is quite a whole lot not doubt. . It also features an auto shutoff capability, so it shuts off when the reservoir is full, and therefore will not cause damage to your grow tent. The water reservoir is removable for easy water disposal.

However, what is really impressive about this small and affordable dehumidifier is that it does come with a digital gauge, so you can set the exact humidity level that works best for your marijuana plants at any given time.

What is also cool is that when the humidity level goes 5% off of your set target, this dehumidifier will turn on by itself to maintain proper humidity levels.


3. Vremi 1 Pint Compact Portable Dehumidifier

Ok, so the Vremi 1 Pint Dehumidifier is in fact one of the smaller, more portable, and more compact options here on our list today.

This thing comes in at 11 x 7 x 4.9 inches, and the 11 inch dimension there is the height, so in terms of space used, this thing barely uses up any space at all, so you can reserve as much space as possible for your weed plants.

On that same note, this dehumidifier is designed to be super energy friendly so it won’t jack up your electricity costs. On that same note, with its small size also comes a very low volume level that won’t disturb you.

The Vremi Dehumidifier is able to dehumidify an area up to 215 square feet, which is no doubt way more than you need for a 4 x 4 grow tent, so you know that it will be effective beyond a shadow of a doubt.

What is also neat here is that this thing comes with a programmable feature so you can set the exact humidity level which your weed plants need. Once the humidity level has been achieved, the Vremi Dehumidifier will shut off, and once the humidity level is no longer desirable, it will turn back on.

One drawback that does need to be mentioned here is that this dehumidifier is very small in terms of how much water it can hold. It has a 0.4 or 1.5 liter water capacity, which is not all that much, and it has the ability to suck up to 1 pint or 480 ml of water from the air per day.

This is not the highest performance option around, as you can tell, but it does still work more than well enough for a very small tent such as a 4 x 4 grow tent.


4. JESE Mini Dehumidifier

This is yet another very small and compact dehumidifier, one that is originally intended for use in small bathrooms, but works very well for small 4 x 4 grow tents as well.

The JESE Mini Dehumidifier is indeed very small and compact, plus very portable too, so it will take up barely any space in your grow tent, thus leaving more space for your pot plants, plus it is also very easy to set up in under 1 minute.

Now, the JESE Mini Dehumidifier is very quiet and operates at under 30 decibels, which is indeed very quiet, plus it is also an energy efficient option as well.

The JESE Mini Dehumidifier is small, so it does have a small water tank, one that can fit up to 18 ounces of water. Moreover, this thing has the ability to pull up to 9 ounces of water from the air per day.

This should be good enough for a very small grow room or grow tent, but beware that you will be emptying this thing fairly often, but at least it has an easy to remove reservoir.

Do keep in mind that the JESE Mini Dehumidifier does not come with a programmable thermostat for precise humidity control. It simply turns on or off with the push of the power button.


5. Pro Breeze Electric Mini Dehumidifier

Here we are moving up a little bit, as the Pro Breeze has a slightly larger water reservoir and an increased ability to suck more water out of the air per day. Now, this thing should still be more than small and compact enough to fit into a 4 x 4 grow room or grow tent with ease.

It might cost you the space for a single plant, but it is a high quality option with a very high level of durability and functionality.

This thing has a 52 ounce water capacity, which is indeed a whole lot of tank space, plus it has the ability to pull up to 18 ounces of water out of the air per day. You won’t have to empty the water reservoir too often, which is convenient no doubt.

The Pro Breeze does have a full tank indicator, and it will shut off on its own when it is full. So, it will definitely be strong enough for a 4 x 4 grow tent, maybe even a bit of overkill actually, as this dehumidifier is designed to work for rooms up to 220 square feet, which is obviously way more than a 4 x 4 grow tent.

This particular dehumidifier is also extremely quiet and energy efficient, both big bonuses that will benefit any space and any bank account. Keep in mind that this thing simply turns on and off, but does not have a programmable function for precise humidity level setting.


6. Afloia Dehumidifier

Here we have another dehumidifier which is intended for a decent size space, one that can function for up to 220 square feet. Once again, a 4 x 4 foot grow tent has nowhere close to 220 square feet of space, so the Afloia Dehumidifier is definitely more than large enough to deal with a small grow tent such as this.

With that being said, this thing is a little bigger than most of the other options we have reviewed here today. Now, while it is not a deal breaker per say, and the Afloia Dehumidifier is still decently compact, it just is not quite as compact and space friendly as some of the others on our list.

Moreover, the Afloia Dehumidifier does have a fairly large 68 or 2 liter water reservoir, which is of a decent size so you won’t have to empty it too often. Also, it has the ability to extract up to 26 ounces or around 800 ml of water per day, so even when running on maximum capacity, you won’t have to empty it more than every 2 days.

When the Afloia Dehumidifier is full, the auto shut off feature will turn it off to ensure that there is no flooding or damage. This thing is also very quiet and operates at just over 40 decibels, which is not bad, plus it is fairly energy efficient too.

However, a drawback here is that the Afloia Dehumidifier does not have a programmable function. It simply turns on or off with the push of a button.


7. Ivation 13-Pint Small-Area Desiccant Dehumidifier

This is a fairly small and compact dehumidifier, but still not as small as the first 5 options on the list today. Now, this thing is a bit too big for a small 4 x 4 grow tent, as it will take up the space of a full plant, which is a drawback indeed. However, with that being said, this thing has some really great features and a high level of functionality too.

To be clear, the Ivation Dehumidifier has the ability to pull up to 13 pints of water from the air per day, but the drawback here is that the water reservoir is just under 4 pints large, so this means that the Ivation Dehumidifier has to be emptied a whole lot, especially when it is running full blast.

This dehumidifier can function for rooms up to 270 square feet in size, which is quite impressive no doubt. It does come with a transparent water level indicator, as well as an auto shut off feature, so it will turn off when full.

This dehumidifier allows you to adjust the desired humidity level in 5% increments, which is pretty useful, plus it also comes with a 12 hour timer so you can set it to run for a certain amount of time.

Even better is that it features an adjustable air vent in the rear, so you can direct airflow as needed. What is super cool about the Ivation dehumidifier is that it doubles as a small space heater, which can definitely come in handy for a grow tent, not to mention that it is still pretty quiet and energy friendly too.


8. Eurgeen Compact 20 Pint Portable Dehumidifier

The Eurgeen Portable Dehumidifier is a fairly compact model in terms of width and length. It is not too large and will not take up a whole lot of space. Now, it does have some height to it, but when it comes to a 4 x 4 grow tent, being a couple feet tall is not going to make a difference.

So, all said and done, this thing will not take up too much space in your grow tent, leaving more room for the plants. To be clear, the Eurgeen dehumidifier is designed to work for rooms between 100 and 200 square feet, so it is way more than enough for a small grow tent.

This dehumidifier is whisper quiet, operating at under 50 decibels, so you will barely be able to hear it, plus it is fairly energy efficient to boot. This dehumidifier does have a full tank auto shut off function so no damage or flooding occurs when it fills up.

Keep in mind that this thing has a 1.5 liter water tank and has the ability to pull up to 20 pints of water out of the air per day.

Now, you will probably have to empty the reservoir on a near daily basis, but it’s not a bad trade off considering how effective the Eurgeen Compact dehumidifier is at its job.

What’s nice here is that this item does come with a programmable display so you can set the exact humidity level that your weed plants need, and it will turn on or off on its own depending to what humidity level it is set to.


9. KEDSUM Electric Small Dehumidifier

The KEDSUM  Small Dehumidifier is actually one of the smaller products on our list today, which makes it ideal for small 4 x 4 foot grow tents. It barely takes up any space whatsoever and leaves it all for your pot plants.

This particular dehumidifier is designed to dehumidify rooms up to 160 square feet, which is obviously way more than enough for a grow tent of this size. Moreover, the KEDSUM has a 700 ml water reservoir and has the ability to pull up to 300 ml of water out of the air per day.

So, if you happen to have it running on full blast, you will have to empty it every 2.5 days, although chances are you won’t have to empty it for a couple days more than that.

This dehumidifier does have an auto shut off feature in the event that it fills up, which is always a good feature. This thing also is very quiet and has a sleep function which makes it run even quieter for night time use.

Keep in mind that this dehumidifier does not have a programmable thermostat. You can just turn it on or off, which is a bit of a drawback.


10. Powilling Cubic Feet Electric Mini Dehumidifier

This might be the final option here on our list today, but still a really good one none the less. This is another really small and compact dehumidifier that will not take up very much space in your grow tent, thus leaving more room for your weed plants.

Although this thing is very small and compact, it is rated for rooms between 160 and 270 square feet, which is more than enough for any small grow tent you might have.

The Powilling Mini Dehumidifier has a water reservoir of 2 liters and has the ability to pull up to 700 ml of water out of the air per day, which is way more than enough for a small grow tent, plus you won’t have to empty it more than twice or three times per week at most.

It does come with an automatic shut off feature so it does not cause flooding or damage in the event that it fills up. This dehumidifier is also fairly quiet and energy friendly.

However, like many small dehumidifiers, it does not come with a programmable function, it just turns on or off.


Commonly Asked Dehumidifier Questions For Growing Weed

Here are the answers to some popular questions we commonly see about dehumidifiers;

What Size Dehumidifier For A Small Grow Tent?

For a small grow tent, such as a 4 x 4 foot grow tent, even the smallest of dehumidifiers will do just fine.

As we mentioned above, the fact of the matter is that a 4 x 4 foot grow tent only has 16 square feet of lateral space, plus the height, so in all reality, finding a dehumidifier that cannot handle a small grow tent like this will actually be a challenge.

Why Use A Dehumidifier For A Grow Tent?

Simply put, weed plants require a specific level of humidity to function and grow properly.

The level of humidity will also influence the temperature level, which also needs to be kept pretty constant at a certain level. The point here is that the rate of nutrient absorption, water evaporation, growth, and the health of the roots all depend on a specific humidity and temperature level.

So, if you have a grow tent and live somewhere the humidity is always high, you will need a dehumidifier to keep the humidity level in the grow tent in check.

We have covered the ideal growing temp and humidity in lots of detail on this article.

Placing A Dehumidifier In Your Grow Room – Proper Placement

In a small grow tent or grow room, the location of the dehumidifier is going to be a pretty big deal.

Since dehumidifiers extract water from the air from a certain direction, and expel the dry air in a certain direction, you need to put the dehumidifier in a central location.

In other words, for a small dehumidifier in a small grow tent, it needs to be placed right in the middle, not along one of the sides.

Keep in mind that there should be at least half a foot of space between the dehumidifier and the cannabis plants.

Is Using A Dehumidifier In My Grow Tent Expensive?

Well, this really depends on the size of the grow tent and the dehumidifier in question.

However, here we are talking about very small grow tents and very small dehumidifiers, so in all reality, you are looking at spending around 8 to 20 dollars per month to run your dehumidifier, which is really not very much at all.

The cost is going to go even lower if you manage to find yourself an energy efficient model.


Conclusion

So, when all is said and done, we do not really want to recommend any one of the products we have reviewed today over any of the others. Generally speaking, most of them are pretty similar, with small differences in their water tank capacity, extraction rates, and programmability.

When it comes down to it, we would recommend going with a dehumidifier that is going to take up minimal space, allows you to set a desired humidity level, and is not too loud. Remember to keep the main purchasing considerations in mind before selecting your own best dehumidifier for a 4 x 4 grow tent.
