What Size Dehumidifier For Grow Room

Growing the plants in an indoor system requires maintenance and other balances to be considered. Maintaining the grow room humidity level is one of the significant considerations. Dehumidifying means not just keeping the grow room wet but also maintaining its optimal dryness. For this purpose, you need to have the right size of a dehumidifier to maintain the temperature.

The thing that needs to be considered that your grow room dehumidifier calculator should be correct. If it goes wrong, the grow room will be either too humid or too dry, and that will be harmful to plants. Here in this article, you will learn what size dehumidifier for grow room you should choose and how to determine the correct size dehumidifier

Basics for dehumidifier’s size for Grow room:

When buying a dehumidifier, there are two things considered to judge the size of the dehumidifier. First, if you are familiar with dehumidifiers, you might notice that all of them have some moisture removal rate. Second, for considering the size, you see the dehumidifier’s performance through its pint rate and know its physical size through its dimensions. Let’s describe both factors briefly

1. The Pint Rate:

Basically, the pint is the unit of moisture that is immersed in the air. When you keep the dehumidifier working all day long, it removes a certain amount of pints within a defined time. Usually, it is calculated how many pints were removed within 24 hours.

So, if a dehumidifier comes with a 30pints/24 hours label, it means the dehumidifier can remove 30 pints in a day. For easiness, we can convert the pints into pounds because 1 pint is equal to one pound.

2. The Physical size:

The physical size is also considered to get a dehumidifier for a grow room. Therefore, you might see some heavy and complex dehumidifiers available in the market, occupying more space. However, some units are available that require very low space because the small grow room dehumidifiers have a compact size.

If you dig more, there are also some micro-level dehumidifiers available that don’t induce any direct dehumidification. Instead, they do passive dehumidification through an absorbent material like silica gel, etc.

Now, if we talk about which dehumidifier is best for grow rooms, then the large dehumidifiers are suitable for large grow rooms having an area of 300 square feet. The other kind, the small dehumidifiers, is ideal for small grow rooms with up to 100 square feet. Finally, the micro dehumidifiers are only best for very small-sized grow boxes that you keep in your interior for decoration, etc.

Requirements for Grow Room:

To determine the right size dehumidifier, you need to put in mind your needs and requirements. First of all, keep in mind the size of grow room and then the activities carried out in grow room all day. Moreover, make a clear statement about the following points:

  • Is there any air conditioner in your grow room to maintain the temperature? If yes, then look at its dehumidification rating that how much moisture it will pull out in a day.
  • Consider the total area of growing room and the amount of water that a plant will receive in a day.

How to determine the right size dehumidifier?

Since we have studied the basics for grow room dehumidifiers, now it’s time to do some practical considerations for the right size dehumidifier. Take some time to consider the right size dehumidifier for growing the room after doing the following calculations. For this purpose, you need to consider some factors; let’s describe each of them.

Factor 1- Need of water per plant:

It’s a reality that the plant leaves the nearby air with vapors; that’s why the grow room becomes humid. If there are a large number of plants in your grow room, it means the humidity level will be high. To balance the humidity level, do an approximate estimation of how much water you feed to the plants, and it will give you an idea of how many vapors you need to dehumidify.

For example, if you have 40 plants in your grow room, it means you need to feed at least 2 gallons of water to each of them every day. Let’s do this with the following grow room humidifier calculator.

Calculations:

2 gallon x 40 plants= 80 gallons (total amount of water required to feed in a day)

1 gallon= 8 pounds

40 gallons= 40 x 8 pounds

40 gallons= 320 pounds

since, 1 pound= 1 pint;

320 pounds= 320 pints

So it means you need to dehumidify 320 pints of moisture from the air within 24 hours.

In short, for pints calculation, apply the following formula:

“Required dehumidifier ability” = (gallons per plant per day) x (number of plants) x 8

Just apply the above simple formula and know how many pints you are required to remove per day. And on the basis of pints, you will get to know how many dehumidifiers for grow room you are required.

Factor 2: Space for the dehumidifier to leave:

For an indoor growing system, you are required to leave the space for plants, the entire setup, fans, air conditioners, the dehumidifier, and other things.

If you are in search for the right grow room dehumidifier size, think about how much space on the ground you can leave. If we talk about some convenient grow room dehumidifiers, they generally requires a space of around 10 x 20 inches on the ground. On the other hand, mini dehumidifiers required 10 inches x 15 inches of space on the ground.

In this case, there could be three scenarios-

There is ample space for convenient dehumidifiers:

In this case, you are at all convenient. You can not only place one convenient dehumidifier, but also there is enough space to install an additional dehumidifier of convenient size. There won’t be an issue, and you can go with one of the Best Dehumidifiers For Grow Room

There is ample space for a mini dehumidifier:

In this case, the space available can only be utilized for mini dehumidifiers, and there’s no space for conventional ones. In such grow room dehumidifier placement issue, you need to buy more than one small dehumidifiers to fill the deficiency.

Space is not enough for mini or convenient dehumidifiers:

Such a case happens when you need to install the dehumidifiers for a tiny grow room set up like a 6×6 or 4×4 grow room. In such a situation, either go for a grow dehumidifier outside grow tent or wall half your grow mini tent.

Applying such a solution, no doubt, will decrease the efficiency, but there is no other option you can go for. Because all is beyond the requirements of your grow room dehumidification.

Factor 3: Grow Room’s Height

Since the dehumidifier can be adjusted easily, the height of the grow room doesn’t matter a lot. However, in case if the grow room’s height is limited to about 10 feet, then it is an important consideration.

You might know that for grow room, the basic rule to place the dehumidifier is to exhibit the face of the dehumidifier into the center of the room. However, if the grow room’s height is short, then it would be difficult to place a dehumidifier in such a position.

To tackle this situation, use an additional support system that can raise the height of the grow room, and the dehumidifier can be adjusted in it easily.
