Humidifier For Grow Tent Buying Guide

Humidifier For Grow Tent Buying Guide

Now you know about the best humidifiers available on the market for use with grow tents. However, knowing about them is winning only half the battle. 

Several factors need to be considered when buying a humidifier for your grow tent. We’ve compiled a detailed buying guide that lists all these essential factors in the following section. 

Going through them will help you understand the elements that should be considered before making a purchase.

1. Humidifier Type

One of the first things to consider is the type of humidifier you plan to get. Generally, humidifiers can be broadly classified into warm mist and cool mist humidifiers. 

Warm mist humidifiers are also known as steam vaporizers and are generally the cheapest option on the market. However, they do use more energy than cool mist humidifiers. On the other hand, most humidifiers available on the market are cool mist humidifiers, 

Cool mist humidifiers may use evaporative technology or ultrasonic technology. For providing your plants with enough moisture, both types of humidifiers can be a great option.

2. Humidifier Size

The size of a humidifier plays a crucial role in determining several aspects of using a humidifier. It affects how long the device can function, where you can place it, what is its water holding capacity, etc. 

For grow tents, which are smaller in size, humidifiers having a compact form factor are the best choice, while you can use larger humidifiers in grow rooms. Smaller humidifiers are also more portable, so you can easily move them about as required to ensure that all your plants are getting enough moisture. 

You need to be careful when selecting a humidifier, as getting a very large one can lead to extra condensation on surfaces, which can be detrimental to plant health. Larger humidifiers can also lead to too much moisture in the atmosphere, leading to the growth of mold as well. Smaller 

3. Tank Size

The size of the tank directly influences how much water a humidifier can hold. The bigger the tank, the longer the period for which a humidifier can run. Larger tanks also help save time and effort since you do not need to keep refilling them at frequent intervals. 

Generally, small-sized humidifiers have a water holding capacity ranging from 200 to 300 ml and can run for 12 hours. You will need to refill the tank about twice a day in such cases. On the other hand, humidifiers with 6-liter tanks can even run continuously for 60 hours. 

However, just as is the case with the humidifier itself, a smaller tank is much more manageable and portable. It can also be cleaned quickly and easily. You will need to select between a more manageable or a large capacity tank. 

4. Ease of Use

Easy to overlook, ease of use is a significant factor when buying a humidifier. Before buying, you should check how easy it is to empty and refill the tank and operate the humidifier. Many devices offer several settings that let you make precise adjustments as required. 

Also, when looking to use it for growing plants indoors, make sure to check how easy it is to move about. In the case of humidifiers that utilize evaporative technology, make sure that the wick is economical and straightforward to replace. Additionally, the controls should also be user-friendly and should not require technical know-how to operate.

5. Maintenance

The level of maintenance that a humidifier requires is also one of the most important things to consider. The easier to maintain a humidifier, the more convenient an option it is. Maintenance involves cleaning the device and taking other steps to ensure that it can run for as long as possible. 

You can find humidifiers that come with easily removable tanks, caps, and other components that make them very easy to clean and maintain. Additionally, spare parts such as caps and tanks should be easily available on the market for a product that you plan to use for a long time. 

6. Additional Features

Manufacturers offer various features to provide a good user experience for their customers. These features may be in the form of night lights, automatic turn-off functionality, mist adjustment, and more. 

Night lights are an aesthetic feature that can help you sleep better at night. Additionally, they can also enable you to see how much water is left in the tank. Similarly, the mist adjustment feature allows you to control the amount of mist being dispersed by the humidifier. 

The auto-shutdown feature is one of the most useful features that automatically turns off the device after a specified time or when the water tank becomes empty. It can also help extend the life of your humidifier, as running on an empty tank can damage it.  

Several options on the market offer different types of features. However, keep in mind that a greater number of features also results in a higher cost. Alternatively, it can even make the user experience unnecessarily complicated. 

7. Customer Service

The first thing to look for in this case is how easily you can contact the manufacturer. The manufacturer’s customer service determines how easily and quickly issues can be resolved. They may provide different means of contacting them, such as by phone, chat, or email. 

Also, speak to other buyers to know how quickly and effectively the manufacturer resolves any issues. The manufacturer’s ability and willingness to honor warranties and guarantees and offer replacements or refunds all form a part of the customer service.

8. Budget

Last but not the least, your budget will determine which humidifier is the most suitable for your needs. Generally, larger humidifiers and those that offer more features are more expensive. Smaller humidifiers may be more affordable, but make sure such products do not compromise quality and performance. 

To be safe, select a product that is neither too costly nor misses out on too many features for the best experience.
