The 8 Best Grow Tent Dehumidifiers for 2023

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

Eva-dry E-333 Renewable dehumidifier

Pros

  • No need for electricity as it uses a moisture absorbing gel
  • Very portable and can be used in a small grow tent or grow box
  • 5-year warranty if anything goes wrong

Cons

  • Not for use grow tents larger than 2×2
  • If the area is large, this dehumidifier is not effective in removing moisture
  • Need to recharge by replacing by getting new moisture absorbing gel packs

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.

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.

  • 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.

Tent Dehumidifier FAQs

How do I choose the right dehumidifier for my grow tent?

When choosing a dehumidifier for your grow tent, consider the size of the grow tent, the humidity levels you want to maintain, the capacity of the dehumidifier, and your budget. It’s also a good idea to look for a dehumidifier that is Energy Star certified, as this will ensure that it meets certain energy efficiency standards.

How do I set up a dehumidifier in my grow tent?

To set up a dehumidifier in your grow tent, first make sure that the dehumidifier is appropriate for the size of your grow tent and that it is capable of maintaining the desired humidity levels for your plants. Next, place the dehumidifier in a convenient location within the grow tent and plug it in. Follow the manufacturer’s instructions for setting the humidity levels and any other features, such as a timer or humidistat.

How do I maintain a dehumidifier?

To ensure that your dehumidifier is functioning properly, it’s important to follow the manufacturer’s instructions for maintenance. This may include cleaning the filters and emptying the water tank on a regular basis.

Can a dehumidifier be harmful to plants?

A dehumidifier can be harmful to plants if it is set too low or is too powerful for the size of the grow tent, as it may remove too much moisture from the air. It’s important to choose a dehumidifier that is well-suited for your specific needs and to monitor the humidity levels in your grow tent to ensure that they are within the optimal range for your plants.

Can I use a dehumidifier in a grow tent with CO2 enrichment?

Yes, you can use a dehumidifier in a grow tent with CO2 enrichment. However, it’s important to monitor the humidity levels in your grow tent to ensure that they are within the optimal range for your plants. CO2 enrichment can sometimes increase the humidity levels in a grow tent, so you may need to adjust the settings on your dehumidifier accordingly.

Does grow tent need dehumidifier?

Whether or not a grow tent needs a dehumidifier depends on a number of factors, including the humidity levels in the grow tent and the specific needs of the plants being grown.

In general, it is a good idea to maintain humidity levels within a certain range that is optimal for the plants being grown. This can vary depending on the type of plants and their stage of growth. For example, seedlings and clones may require higher humidity levels than mature plants.

If the humidity levels in your grow tent are too high, it can lead to a number of problems for your plants, including the growth of mold and mildew, the proliferation of pests such as mites and thrips, and reduced air quality. In these cases, a dehumidifier can be beneficial in helping to reduce the humidity levels to a more optimal range.

On the other hand, if the humidity levels in your grow tent are already within the optimal range for your plants, a dehumidifier may not be necessary. In this case, it’s important to monitor the humidity levels regularly to ensure they remain within the desired range.

Where should dehumidifier be placed in grow tent?

The best place to place a dehumidifier in a grow tent will depend on the size and layout of the tent, as well as the location of your plants. In general, it is a good idea to position the dehumidifier in a central location within the grow tent, as this will help it effectively circulate the air and remove excess moisture.

If your grow tent is small, you may want to place the dehumidifier directly next to your plants to ensure that they are getting the optimal amount of moisture. However, if your grow tent is larger, you may want to position the dehumidifier near the center of the tent to help evenly distribute the air.

It’s also a good idea to make sure that the dehumidifier has access to a power outlet and that the power cord is not obstructing the movement of people or plants within the grow tent.

Will a dehumidifier cool a grow room?

A dehumidifier may be able to help lower the temperature in a grow room or grow tent slightly by removing excess moisture from the air. This is because moisture in the air can contribute to the overall humidity level, which can make the air feel warmer and more uncomfortable.

However, it’s important to note that a dehumidifier is not a primary cooling device and is not designed to significantly lower the temperature in a grow room or grow tent. If you need to lower the temperature in your grow space, it may be more effective to use an air conditioning unit or a cooling system specifically designed for grow rooms.

Will a dehumidifier stop mold growth?

A dehumidifier can help reduce the risk of mold growth in a grow tent or other enclosed space by removing excess moisture from the air. However, it’s important to note that a dehumidifier is not a guarantee against mold growth, and there are other factors that can contribute to the growth of mold, such as poor ventilation and the presence of organic materials.

To help prevent mold growth, it’s important to maintain the humidity levels within the optimal range for your specific plants and to ensure that your grow tent has proper ventilation. This can help reduce the risk of excess moisture building up in the air and help prevent the growth of mold.

It’s also a good idea to regularly inspect your grow tent for signs of mold, such as discoloration or a musty smell, and to take steps to address any issues as soon as they are detected. This may include cleaning and sanitizing the grow tent, improving ventilation, and adjusting the humidity levels.
