The 8 Best Grow Tent Dehumidifiers for 2023

A dehumidifier is a device that is used to remove excess moisture from the air in a grow tent or other enclosed space. This can be beneficial for a number of reasons, especially when it comes to growing plants.

Excess moisture in the air can lead to a number of problems for plants, including:

• Encouraging the growth of mold and mildew, which can harm or kill plants
• Creating an environment that is conducive to pests such as mites and thrips, which can also harm or kill plants
• Reducing the overall quality of the air, which can negatively impact the health and growth of plants

By using a dehumidifier, you can reduce the humidity levels in your grow tent to a more optimal range for your plants. This can help improve their overall health and growth, as well as reduce the risk of mold, pests, and other problems.

There are a number of different types of dehumidifiers on the market, so it’s important to choose one that is suitable for the size and needs of your grow tent. Some factors to consider when selecting a dehumidifier include the size of the grow tent, the humidity levels you want to maintain, and your budget.

#1.Eva-dry E-333 Renewable dehumidifier

When I started to test growing plants indoors, I only had about five plants that didn’t need much watering.I used Eva-Dry E-333 Renewable Mini-Dehumidifier, and it worked wonderfully. It’s very remote as it doesn’t require any cords or even batteries to operate. Setting it up was effortless!

This works best if you have a grow tent or a room that’s not too big. Now its manufacturer claims that this mini device will work with an area that’s 333 square meters big, but I’d say not really.This is best for 2×2 tents (or smaller), so don’t get this if you plan on setting up a big garage as your indoor garden.

It’s said to remove 4-6 ounces of humidity in 2-4 weeks. That’s pretty much an ounce or two a week, so again this is only good for a small grow tent or box. When it comes to how long it should last, I find it great. This piece is rechargeable. It doesn’t really work with batteries but let me explain further.

This device works with a blue silica gel that serves as the moist absorber. That’ll last about 4 weeks, depending on how damp the area is.Now don’t worry about how it only lasts for a month because true to its name that it is renewable, you have to recharge it until the gel easily seen on its face turns pink. Amazingly, its manufacturer claims that you can keep this for ten years.

#2.Vremi 22 Pint 1,500 Sq. Ft.

A distinctive feature of this model is the presence of an Energy Star rating. sticker on the packaging indicates that the energy consumption of dehumidifiers is about 20 to 30% lower than that of comparable models. General characteristics of Vremi 22 dehumidifier:

If you set humidity level, a range of 5% is maintained. There are also two basic modes of operation: normal mode (with a slight cooling of air), and “comfort“, in which fan speed is reduced, but the ambient temperature does not change.

#3.hOmeLabs 1,500 Sq. Ft Energy Star Dehumidifier

It’s absolutely gorgeous and has tremendous functionality. The honeycomb design grill on the side looks really nice. Comes with several features. You can move the unit around without any hassle due to the caster wheels at the bottom.

There are three options for drainage. First, when the bucket gets full unit shuts off automatically, and you empty the bucket. The second way is continuous draining. The third way is a quarter-inch pump hose; when the bucket is full pump will turn on to empty the bucket.

Unlike thermoelectric dehumidifiers, its control panel is loaded with options. It has a humidistat so that you can set it to comfort, continuous, or turbo mode. You can also adjust humidity manually. The display shows you the current humidity level, and if you press the arrows, it will show you your target level, and you can change it by increments of 5%.You will have to set it again at the end of each cycle. The unit is fairly quiet at 59 dB. In turbo mode noise level is high but no more than a wall heater with a fan. The trial went on for a month and did pretty well. When can take humidity down to 65% form 82% within 30 minutes.

Tests show that continuous mode is its default setting; turn it off if you don’t want it to run nonstop. A microwave like a beep is the indication to empty the bucket. This machine can run nonstop by using the continuous function and condensate pump. Depending on the environment, air filters can get clogged and dusty. Clean it aver 2 weeks or so.

It is an excellent little powerhouse from Vremi. It comes in a super sleek package, is designed to remove 22 pints of water from the air daily, and can hold up to a gallon of water. The Control panel is full of functions.

The filter button reminds you to clean the filter. It will flash after 250 hrs of operation. In comfort, zone humidity cannot be adjusted manually; instead, it is preset to recommended healthy level based on ambient temperature. The Turbo button is for maximum water removal.

The timer button allows you to auto-start and auto-off the unit. Humidistat will allow you to adjust humidity manually. On the first day, we ran it for about 9 hours. The humidity started at 63%, and by the time we turned it off, it was sitting at 40%. The humidity reading on the unit matched my humidistat reading.

We are quite impressed so far; you can leave this running pretty much all day without having any problem. It makes some noise (when it’s on turbo mode, it’s like a medium quiet bath fan), but in non-turbo mode, I find it like a background hum. The filter grille is easy to remove and makes cleaning easy. We didn’t connect it to the hose; the holding tank comes with a little handle, making it easy to dump.Notice the beeping; it lets you know the container is open. The built-in power cord holder makes it easy to store the cord.

Tent Dehumidifier Buying Guide

When shopping for a dehumidifier for your grow tent, there are a few key factors to consider:

• Size: It’s important to choose a dehumidifier that is appropriate for the size of your grow tent. If the dehumidifier is too small, it may not be able to effectively reduce the humidity levels in the tent. On the other hand, if it’s too large, it may be more expensive to operate and could potentially remove too much moisture from the air, which could be harmful to your plants.
• Humidity levels: Different plants have different humidity requirements, so it’s important to choose a dehumidifier that can maintain the desired humidity levels for your specific plants. You can use a hygrometer to measure the humidity levels in your grow tent and select a dehumidifier that is capable of maintaining those levels.
• Capacity: Dehumidifiers are rated based on their capacity, which is the amount of moisture they can remove from the air over a certain period of time. It’s important to choose a dehumidifier with a capacity that is sufficient for your grow tent.
• Price: Dehumidifiers come in a range of price points, so it’s important to consider your budget when shopping for one. Keep in mind that more expensive dehumidifiers may offer additional features or be more energy efficient, but they may not always be the best choice for everyone.
• Features: Some dehumidifiers come with additional features that may be useful for your grow tent, such as a timer, a humidistat (which allows you to set a target humidity level), and an automatic shut-off function.
• Energy efficiency: Dehumidifiers can be expensive to operate, especially if you need to run them for extended periods of time. Look for a dehumidifier that is Energy Star certified, as this will ensure that it meets certain energy efficiency standards.

By considering these factors, you can choose a dehumidifier that is well-suited for your grow tent and meets your specific needs and budget.

There are also some potential disadvantages to using a dehumidifier in a grow tent:

• Cost: Dehumidifiers can be expensive to purchase and operate, especially if you need to run them for extended periods of time.
• Noise: Some dehumidifiers can be noisy, which may be a problem if you have a small grow tent or if you need to run the dehumidifier at night.
• Maintenance: Dehumidifiers require regular maintenance to ensure they are functioning properly. This can include cleaning the filters and emptying the water tank.
• Risk of removing too much moisture: If the dehumidifier is set too low or is too powerful for the size of your grow tent, it could potentially remove too much moisture from the air, which could be harmful to your plants.

The advantages of using a dehumidifier in a grow tent generally outweigh the disadvantages, as long as you choose a dehumidifier that is well-suited for your specific needs and use it properly.
