It has got a good dehumidification capacity doesn’t essentially require that it has to be super hard to control. In fact, all you have to do is to adjust the ideal moisture level. Once done, it will repeat itself for a cycle of 24 hours until the water tank is fulfilled.

Wait, there is more to talk about the control.

The hOmeLabs HME020030N  sports a touch control panel where features like defrost, restart and turbo modes are embedded right in. Not overwhelming, but it can certainly be labeled as a dehumidifier ahead of its time.

Worrying about the safety issues? Well, the tank is able to shut off itself once the water tank is full. In case you’re out of time to empty up the tank yourself, there is a drain hose outlet that will keep the draining process going. No additional timer, no constant monitoring.

Isn’t it convenient for a busy grower?

One of the biggest eye-catching virtues of this model is, it’s compact design and beautiful aesthetics. The sleek clean look, compact footprint (15.2 x 10.2 x 19.7 inches only), and the soothing outfit- all are meant to be a show stopper. Therefore, you can make use of it in your living room, bedroom and anywhere when it’s not being used in the grow room.

Talking about transporting it from grow room to anywhere else, there are built-in castor wheels and handles that make the task easy. The overall weight is about 30 pounds. So, no hardship there as well.

3 Best Dehumidifiers for Grow Room

1. Vremi 30-Pint Energy Star Dehumidifier

Product Overview

If we focus our radar on the dehumidifiers that are only meant to be for grow rooms, then this model from Vremi rules the list. And we have got quite some evidence behind such claims. We’ll break them up into bite-size chunks below –

Vremi Dehumidifier

First things first, it’s the dehumidifying and purifying job that it does. Well, you can say that it’s not just a dehumidifying device, but also an air purifier. Firstly, It can remove 4 gallons of moisture control at a 30-pint rate, and that would be more than sufficient for a grow room up to 1000 square feet. Secondly, it can eliminate moisture, odor and any other nasties from the air.

There are many users (growers) who are literally hateful of the job of air filter removal and cleaning when it’s about dehumidifiers. But this one from Maniac is a pretty fine exception. It’s easy to take on and off, and you have to do that once in a month only. If you use it less often, cleaning the filter once in a couple of months will also do.

Want to make multi-purpose use of it? Well, it will definitely let you do so. Even, to make your job of transporting it from one room to another, they’ve provided it with a wheel castor. The weight of this device is around 31 pounds, which is another plus point in terms of portability. All you have to do it is set it at a suitable position and set the timer up.

The summary line is, the Vremi 30-pint Dehumidifier is a nicely built, efficient, portable dehumidifier that can also do air purifying on your behalf. Overall, it’s a good investment for both the grow room and the home.

What Is A Dehumidifier?

Simply put- dehumidifier is an electric or non-electric system that takes off the moisture content from a humid air. It works usually within a confined area like grow rooms, grow tents, basements, bedrooms, bathroom, show boxes and many more.

The technology that is used in dehumidifier collects moisture content from the air and converts them into plain water. Therefore, these devices come with a water reservoir, which should be replaced after a regular period of time.

Types of Grow Dehumidifier

The classification of grow dehumidifier can be done from two points of view. The first one is based on the area that you’re able to work on, and the second one is the dehumidifying technology that it’s up to.

Here is the first perspective-

  1. Dehumidifier for grow room: They are with high dehumidifying capacity, and the power consumption is also more than other types. They are bulky in size, but a number of portable models are in there.
  2. Dehumidifiers for grow tent: These are quite smaller and lighter compared to the first type. They use almost the same technology but to a smaller degree. Therefore, they can cover up spaces of up to 300-500 square feet.
  3. Dehumidifier for grow boxes: They’re quite small, mostly non-electric type. They don’t require electric power and that’s sufficient to cover up small grow boxes, shoe boxes, cabinets, etc.

In the second kind of classification, here you go-

  1. Electric Dehumidifier: These are based on an electric formula to attain water contaminants from humid air. They run off 115V usually, and they can take out around 10-16 ounces of moisture in a day.
  2. Non-electric Dehumidifier: These are rather passive dehumidifying systems that use silica gel layers to absorb water contaminants from the air. A passive airflow is needed to be induced with these models.

Buyer’s Guide

Hopefully, you’ve been going through all 11 of the best dehumidifiers for grow systems and made your shortlist already. To hone up even more, here is an extensive buyer’s guide for you-

The Rate of Dehumidifying

Of course, that’s the first thing to look up in a dehumidifier device. Most of the large-scale dehumidifiers can take up to 18-20oz of water containment in a day. In the case of smaller units, 8-12oz of moisture removal is expected. However, with increased dehumidifying ability, the power consumption raises up.

The Portability

You don’t want your dehumidifier to stuck in one stationary place, do you? Therefore, make sure that it’s got enough portability. Usually, there are top handles, rear handles, side handles, castors, etc. to make them portable.

The Area Coverage

Usually, each of the models come up with a fixed label of how much area it can cover. Therefore, you should have an estimation of what area size you are dealing with, and pick up the right model accordingly.

The Air Purifying Ability

Nowadays, there are many models that provide you with an air purifying service along with dehumidifying. They use to remove allergens, dust, dust mites, mold, mildew buildups, and other similar pollutants. In case you can grab one that can serve you in both ways, that’s a jackpot.

Bottom Line

Alright, so that’s the end of this long article on best dehumidifier for grow tent and rooms. Hopefully, the list had been resourceful, and you’ve picked up the right one within your budget.
