Why Run A Grow Room Dehumidifier?

So, why can we grow plants indoors without the need for a dehumidifier, and why is that? I’ve already addressed its most fundamental usage and purpose, which is to manage humidity in your grow room and prevent excessive moisture from building up in your environment. If you’re wondering how it accomplishes this, the answer is straightforward. It essentially draws moisture from the surrounding air. Of course, the moisture that it receives does not just evaporate. Moisture is collected and held in a pan or a container that comes with the product.

  1. Some humidifiers do not need the use of a container.
  2. In that case, the dehumidifier is merely equipped with a couple of tubing connections that might go to a collecting vessel or drainage.
  3. It is necessary to maintain a sufficient humidity level in your growing space in order to keep your plants healthy.
  4. Another possibility is the development of bud rot.
  5. It normally begins by hiding and growing inside a blossom.

It would suffocate your air and kill your plants, among other things. Prevention is always preferable to cure, as the adage goes. Once molds begin to wreak havoc on your indoor garden, it’s as if you’ve started over from the beginning.

Evaluating Your Grow Room’s Dehumidification Needs

Knowing the size of your grow room is important information since it will help you decide how many dehumidifiers you will require and where each of them should be located. The number of plants you intend to raise should be taken into consideration when determining the size of your growing space. The amount of water you’ll need in a day will be determined by this, and after you know more about it, you’ll be able to easily estimate the amount of moisture and humidity your space should have on hand.

  • When it comes to temperature control, it’s best to maintain the room between 70 and 80 degrees Fahrenheit.
  • Flowers would have a greater chance of surviving in the upper range.
  • Having a high humidity level in your grow room will make it difficult to use CO2 equipment effectively.
  • Providing that it is located in a secluded and cool location and that you do not intend to visit it frequently, further permit is no longer required.

How To Choose The Right Size DehumidifierFor Grow TentGrow Room

Avoid stressing over estimating the size of and number of dehumidifiers you should have because this is straightforward math. To illustrate what you should bear in mind while determining how your dehumidifier should operate, consider the following: If a plant wants one gallon of water per day, then a modest grow room with 20 plants will require twenty gallons of water per day on average. Because a gallon of water is equivalent to 8 pints, this equates to a total of 120 pints of water used in a day.

A pint of moisture is equal to one pound of moisture, thus a room with 20 plants requires 5 pounds of moisture every hour to keep them alive.

Of course, the larger the size, the more expensive it will be to purchase.

Things To Consider When Buying A Good Grow Tent Dehumidifier

Because humidity and temperature are closely related, it’s important to get a dehumidifier that can operate efficiently regardless of the temperature outside the home. Keep in mind that the cooler the environment within your home, the more likely it is that your dehumidifier will not be used to its maximum potential. The size of your dehumidifier will be determined by the number of plants you have and the size of your grow room, although you are free to purchase a large-capacity dehumidifier if you so choose.

It simply implies that you won’t have to dispose of water as frequently as before. There are dehumidifiers for both industrial and domestic use accessible to you. While this is true for small spaces (such as a 4×4 grow tent), a household dehumidifier should enough for most people’s needs.


If your grow area necessitates the use of many dehumidifiers, it is preferable if they are evenly placed. I must emphasize that positioning dehumidifiers in the proper places of your grow tent or grow room is critical to ensuring that your plants reap the benefits of the dehumidifiers’ intended purpose. I cannot stress this enough. If you’re producing crops, putting it in the improper spot might have a negative impact on your yield or the lifetime of your plants in general. The dehumidifier should be placed in the middle of the room, on the same level as the lights, if possible, especially if you just want a single device to reduce the humidity in the space.

If you only have one dehumidifier in the room, and it is located in the middle of the room, you should not have any problems with ventilation.

Just keep in mind to refer to your dehumidifier’s instruction manual for the precise spacing requirements.

What is the best setting for my dehumidifier?

The relative humidity levels in your location might reach as high as 80 percent at some points. Even in a residential area, this is hardly an ideal situation. In all cases, 30 percent to 60 percent would be the optimal setting.

What should my humidity be during flowering?

Because the optimal humidity level is between 30 and 60 percent, it is best to retain the humidity level in the center of that range during the flowering period. Specifically, during the blossoming period, a humidity setting of 40 percent to 50 percent is recommended.

Are dehumidifiers expensive to run?

A basic dehumidifier unit with a capacity of 30 pints runs at a maximum of 280 Watts per hour on average. Using a dehumidifier throughout the day should only cost you approximately 50 cents per day if you use it all day. As a result, you just have to spend $15-$16 every month to cover the cost of it. Be aware that if the temperature in your home drops, the dehumidifier will most likely use more energy to extract moisture.

The Bottom Line

The Complete Buying Guide may be found here.

Why do you need a dehumidifier in a Grow Tent?

A humidifier removes a significant amount of moisture from the air and stores it in a water tank since moisture cannot simply evaporate. The tank that comes with a dehumidifier is proportional to the size of the dehumidifier. The water from certain humidifiers does not need to be collected since it drains via the drainage system or gathers in a vessel. Other humidifiers are intended to reuse the moisture that they gather, which helps to keep the humidity levels stable. However, the most important purpose for using a dehumidifier is to keep your plants from becoming infected with a fungal illness such as powdery mildew or fungus.

Furthermore, excessive wetness causes the air in grow tents to get stale, resulting in the death of plants.

How many dehumidifiers do you need?

You might be wondering if you’ll need to purchase more than one dehumidifier to meet your needs. The size of your grow tent will assist you in determining the quantity of dehumidifiers that will be required to meet your requirements. In addition, the number of plants you are growing will inform you how much water you will require in a given day. As soon as you have a good idea of how much water you will need each day, you can calculate the humidity and moisture levels in your grow tent. Because we are concentrating on a 44 grow tent that can accommodate four to six plants, you may work with these numbers as a starting point.

The ideal temperature for your tent is between 70 and 80 degrees Fahrenheit, which is ideal for growing vegetables and flowers. High humidity levels will interfere with the operation of your CO2 equipment; as a result, the CO2 levels should be in sync with the operation of your dehumidifier.

Dehumidifier features

When selecting the best dehumidifier for your 4×4 grow tent, it is critical to search for features that are unique to the product. The auto-restart function allows dehumidifiers to restart themselves after a power failure. A dehumidifier can help you avoid worrying about the humidity in your grow tent in the event of a power loss by allowing you to keep it running. It also allows you to devote more time to other activities rather than rushing back to your tent to check on your plants every now and then.

  1. These characteristics make dehumidifiers simple to operate and allow them to be fully automated.

It will take up valuable space and will not perform the functions you want. Increasing the relative humidity outside the tent is necessary if you are continually cycling air from outside the tent.

THE MOST EFFECTIVE DEHUMIDIFIER FOR A GROW TENT: A growing system in an indoor environment can be ruined by moisture, pollution, and odor. Furthermore, if you intend to cultivate plants, particularly cannabis, in an indoor environment, you will require a well-ventilated grow room for your plants to thrive. It is important to note that simply purchasing a grow tent is not sufficient, even though it is the first step towards your indoor plantation and it is critical for plants to have a healthy environment in the grow tent.

Dehumidifiers are extremely important, despite the fact that the name implies that they only dry out the air, when in fact, they do much more than that; they control moisture, which prevents the growth of mold and dust mites, among other things.

Using a dehumidifier, air is drawn over cold coils, which condenses out moisture, before being drawn over warm coils and returned to the grow tent or room.

With all of the different brands and products available, there is always a better option for you to choose from.

However, in order to assist you, we have researched some of the best dehumidifiers available. All of the products listed below are the best in their respective categories, as determined by our research team, which spent 50 hours last week collecting and generating opinion about them.


In terms of performance, the VIVOSUN tiny grow tent dehumidifier is the most effective one available on the market. This product is the appropriate size for most grow tents and will fit most of them. This dehumidifier has a capacity of 400ml per day and can effectively clean the air in confined, compact rooms and areas due to its modest size. Its modest size is a benefit, since it only occupies a little area of your tent and has a built-in handle that makes it easy to move. However, in contrast to its functioning mechanism, the VIVOSUN compact dehumidifier is extremely simple to use and run.

While in operation, the dehumidifier is quite quiet, so it will not bother you or your neighbors.

It has the potential to dehumidify four gallons of air in an afternoon, which is rather impressive. As a result, it would have little trouble keeping a 1056 square foot development room dry. That’s what we refer to as “large grow rooms” and “greenhouses” in the indoor gardening industry’s regulation book. As a result, the Inofia 30-Pint Dehumidifier meets our high standards for a dehumidifier for a large development space. Moving forward, the water tank and the drainage system are the next two items on the list.
