1. Honeywell HEV355C: Best Overall Grow Humidifier

Highlighted Features

  • UV technology to kill 99.99% of the germs.
  • The moisture is taken care of with Evaporative Technology.
  • Keeps the humidity within the expected range of 40-60%.
  • Uses only 60W of energy.
  • Reduces static electricity around the area.
  • Can cover an area within 500 square feet.

Product Overview

After a week of research, we got to label Honeywell HEV355C as the best overall grow humidifier under any budget. And you might be wondering about the reason behind. Well, here we go with the enlightened discussion on its features and specs.

The sole reason that makes the Honeywell HEV355C better than anyone else is- it’s the ability to deliver pure, germ-free air. We’re not stating that it’s a full formal air purifier. But it has got a UV technology that solely kills 99.99% of the germs in the water. When the water vapors get into the regular room air, that’s what makes it purer.

Do you love your air when it becomes too humid? If the answer is negative, then you might fall for Honeywell HEV355C anyway. Because in this device, there is an evaporative technology that filters the vapor before releasing it. Therefore, the cool mist gets into the air faster than any other form of it.

The ideal humidity level for any grow room or tent is 40-60 percent. And this evaporative humidifier does exactly that to keep your plants healthy. And do that, all it needs is 60W of energy power. So, you don’t have to worry about a sudden spike in the electricity bill of your home.

Moreover, the diverse range of uses of this model is another selling point that we would like to highlight. What we mean is, in case you find the grow room humid enough, you can take that out and use it into your bedroom, living room or so on. It would bring better sleep, and ensure better breathes as well.

One tiny drawback that we’ve seen so far is the small tank size. The water tank sizes only 1 gallon. And that would keep the device going for only 24 hours. But if you want to check it out once in a day, then this should not be any major issue anymore. Fingers crossed!

The verdict from our side? No matter it’s the indoor nursery or grows set up or even the human, the honeywell cool moisture humidifier would make a perfect companion as long as the concern of humidity is taken.

  • Promises a pure, breathable air for both human and plants.
  • Easy-to-fill and refill the water tank.
  • Protects wooden furniture and utensils.
  • Deals with sanitized water.
  • Kills bacteria, fungus, viruses, and germs.
  • Only 1.1 gallon of water tank size.

Product Overview

As the runner’s up to pick of today’s contest, we’ve decided to name something that’s just perfect for a grow tent or small grow room of up to 250 square feet of area size. Because, most of the non-commercial indoor growers grow inside this size of tents, and VIVOSUN is that one model that they are in search for.

To put flesh on the skeleton of our decision, let’s explain the humidifying capacity in the first place. The electric humidifier has low energy consumption, 85-90 percent less electricity than a normal stream humidifier. And that is quite able to cover up an area of 250 square feet or smaller.

Ensuring a top-notch, uniform distribution of the mist is something where most of the brands struggle with. But this model from VIVOSUN is not one of them. There is a 360°degree rotating nozzle ensures an even level of humidity. With that, you can defocus on the areas of your grow tent where the electrical equipment or lights are located.

Moving forward from the humidification to the usability, we get to have a way to fill a 6-liter want tank. Unlike other models, you don’t have to entirely break the device down to separate the tank. Once it’s done, the assembly of the tank is hassle-free as well. In case you want to clean it anyway, it would take too much of effort.

Now come to the question of the longevity of the device. Well, the lasting period of VIVOSUN is up to 20 hours. So, if you run it for an entire day-night cycle, you have to replace the water in the tank. But when it’s humidifying your little grow room, this maintenance task is worth the investment.

  • Remote control included with the humidifier.
  • Customized humidity.
  • Safe to use with auto turning off.
  • Can provide overnight protection.
  • Night light as an optional feature.
  • Quite beautiful aesthetics.
  • A compact footprint takes less space.
  • Have to refill the water tank frequently.

Product Overview

It’s more than possible to find an effective but cheap humidifier in today’s marketplace. Upon deep research on the specs and features, we couldn’t help recognizing the LEVOIT Cool Mist Humidifier as our best rated grow room humidifier. And below is our LEVOIT humidifier review explaining why.

As long as a humidification of a grow room is concerned, the mist output has to be quick and high. This product from Levoit is able to provide 300ml of water-to-mist conversion in an hour. And that is it’s the best capacity. In case you need lower humidification, there are two more options as well.

One standout feature of Classic 200 is its Aromatherapy. In case you want to make use of it in bedrooms or living room, you won’t mind aromatizing the air up, right? So, just put your favorite essential oil to the oil diffuser of it. And whoa! You’ve got a device that provides both aroma and humidity at the same time.

The water tank is, of course, a key feature to look at. And the 4L water tank for this model just ticks the box of any large-scale grower. On regular service, this tank would take up to 40 hours of operation to get it full. So, you have to empty it up after almost one and a half months (almost).

In terms of ease in use and safety in operation, we’d got a couple of good news. Firstly, there is a 3.8 inches tank opening that makes it easy to refill without any spill. Secondly, there is an auto shut off feature that is on the duty of shutting the device whenever there is over humidification.

So, we can come to a verdict that it’s quite safe to use and easy to operate as well. To operate it at its fullest, you don’t need to be an expert grower or so. All you have to do is to make it an imperative part of your grow room setup.

  • A filter-free humidifier.
  • The compact footprint will eat up less space.
  • Easy to refill and set back on track.
  • Whisper quiet operation.
  • Less risky and spill-proof water tank.

Product Overview

A significant selling point of this humidifier is the size of its water tank and run time. As you know, the water tank is quite an essential part of a humidifier. But specifically, it is the size of the water tank that decides for how long you can run the humidifier at a stretch. But with this 4 liter tank and auto-sensing mist levels, you don’t have to think refilling this humidifier for up to 40 hours depending on your setup.

Based on the plants you rare cultivating, you have to set the humidity level and the machine auto sets the mist level for you. 

Worrying about the noise output? Of course, you should, as long as household usage of a humidifier is concerned. But the good news is, this model only operates at a noise level of 26 dB, which is quite less disturbing if you think about it.

A number of safety features had been embedded into it, among which the automatic shut-off feature stands out. You can set the timer between 1 to 12 hours of run-time, and it will automatically shut the device off right after.

With that much big of a water tank inside, this model can literally serve your indoor garden for up to 50 straight hours. In terms of working hours in a row, this Everlasting Comfort Humidifier is one of the top picks of the current market.

Sometimes, you would love to hide the smell that generates from the indoor garden. In that case, the essential oil tray can be the savior.

Still, selecting the right humidifier (based on area of coverage) becomes a tough chore to go with for most growers. The CTOMOA 4L gets our vote for best cool mist humidifier becasue, even though it specifies 107-322 sqft, it has enough adjustability to service smaller areas and go longer between refills.

To support the humidifier to keep misting the grow room, there is a 4-liter water tank inside. An emptied-up water tank can keep the operation going on for 12-30 hours at least. Although this timespan depends largely on the misting level that you are dealing with. But that’s a quite satisfactory duration though.

What about the control? Well, there is a built-in humidistat that displays essential data through the LED display panel. Also, you can watch the current relative humidity (Rh) level and set run timers to help make sure you aren’t over humidifying your grow area.

Product Overview

Mists can be divided into two clear classes- warm mist and cold mists. We have talked about cold mist humidifiers before, as you’ve seen. At this point of the best humidifier for grow tent review, we would like to talk about our favorite pick as the best warm mist humidifier- the Vicks 1.2-Gallon.

At first, let us talk about the purpose of using a warm mist humidifier. In case you are seeking for a humidifier in the winter season, cold mist humidifiers won’t be a right suit. Because they might provide enough humidity to the grow tent, but they will lower the temperature even more down. And in winter, that’s not expected at all.

That’s where the role of Vicks cool mist humidifier comes as a solution. It doesn’t drop the temperature and still provides the space with enough humidity.

Moving forward, the regular features of what we expect from a humidifier are still present in this model pretty finely. It has got a 1.2-gallon water tank, which is perfect for running this device for 30 hours. So, you have to replace the water inside the tank once in a day.

The mist that it produces, is 95% free of bacteria and germs. So, you can say that it won’t reach any kind of safety threats to both your plants or the people nearby.

Talking about the people nearby, in case you decide to make some occasional use of this device out of your grow tent, it will be a great idea. Because it releases cough and congestion. In fact, there are some common problems that take place because of the dry air in winter. This humidifier can, of course, help you out with that.

  • Helps the plants to breathe easier.
  • Works as a cough and congestion relief as well.
  • Provides with enough moisture in winter.
  • Works as a companion of both indoor garden and regular use.
  • Not a good one to go within summer.

What Does A Humidifier Do?

First thing first, humidifiers have the important capacity of increasing the moisture count in any given area by providing the air with water vapor. This can be in the form of either cool mist or hot mist. And the choice between these two types will decide whether a humidifier would increase or decrease the temperature.

Here are what does a humidifier do –

Raise the Humidity

Of course, as the name of these products suggests, humidifiers can humidify a certain area. And to get a visibly significant raise in the humidity (RH), the area has to be confined. Grow rooms, grow tents, bedroom, living room, bathroom, etc are the ideals examples.

Based on the rate of humidifying, you have a certain time-span to raise the level of relative humidity from point A to point B. Once you’ve achieved the right RH, all your humidifier needs to do is keep up to that.

Change The Temperature

We cannot directly state that humidifiers can directly on the temperature in either a positive or negative manner. Because some of them can raise the temperature, where some of them can lower it down.

From that point of view, there are two clear types of humidifiers:

  1. Cool mist humidifier: Releases mist in a cool form of temperature.
  2. Hot mist humidifier: Releases vapor in a hot form of temperature.

Buyer’s Guide For the Best Humidifier For Grow Room And Tent

By now, we expect you to make a shortlist of the products that you want to pick up your final one from. But before you make up your mind, we’d urge you to go through the crucial buying considerations below-

The area coverage

First of all, it’s the size of the room that your humidifier is able to cover up. It basically depends on two data- the humidifying rate, and the run-time of the device. Both of these data vary from model to model.

In case you are growing in a tent; you should look for one humidifier that can cover around 100 square feet of area. In the case of larger sized tents or rooms, there are models that can cover up to 600 square feet of the area as well.

The size of the water tank

Every humidifier comes with a water tank, as it’s an imperative part of the mechanism. Now the question is, how much of water it can hold into its tank?

If the size is something as small as 1 gallon, you need to replace the water in it in every 12 to 16 hours. On the other hand, there are some models that can come up with up to 6 liters of water tank size. For those, the water changing frequency is less happening.

The humidity settings

The humidity settings or the misting settings are the amounts of humidification done by the device. If you want to take up faster humidification, there should be high settings such as 300 ml of water in an hour. In the case of smaller rooms, you might go for smaller settings.

Overall, make sure that your device comes up with at least three different misting settings in it.

The safety features

Safety is quite essential as long as an electrical device like a humidifier is taken under the radar of a buyer. What usual models come up with as a safety concern, is the automatic shut off.

Now, this particular feature might be automated, or programmable. If it’s automized, it will detect the humidity level and shut off automatically when it’s humid enough. On the other hand, some of the modules might take a preset time-span and shut off automatically after the time is up. And this is applicable for best dehumidifiers as well.

When Should I Use A Humidifier For My Plants?

If you take indoor gardening as a concern, there are some certain stages of the plants that require a good humidity in the air. To be specific, these are the two stages of plants- Seedling and Germination. Let us explain why-

Why would you need high humidity in germination?

During the germinating age, plant’s root takes place in growth. A very high humidity level is expected to be maintained by them. In case you don’t raise the humidity of the entire environment, you can try using humidity domes.

Expected Humidity Level to Maintain: 60-70% Rh

Why would you need high humidity in vegetation?

Throughout the vegetative stage, the growth of the plant’s body and the leaves take place. So, they would require a good amount of vapor in the air. A partial water consumption is done by the root. But still, the demand for in-air humidification is imperative.
