Our Reviews

Inofia Dehumidifier

One of the most important factors that will affect the growth of indoor cannabis plants is humidity. It’s important that you’re in control of the temperature otherwise your plants won’t have a good atmosphere to grow in.

If the humidity in your grow tent or grow room is higher or lower than required, it will have a negative effect on your plants because they’ll be prone to diseases if the humidity is out of control.

The Inofia dehumidifier provides reliable operation and efficiently removes up to 70 pints of excess moisture per day. The adjustable humidistat automatically detects humidity in the air and adjusts to keep the relative humidity at your desired level. This control and user adjustability are perfect for growing weed!

The Inofia dehumidifier boasts intelligent humidity level control and can be set between 30% RH and 80% RH. The inbuilt hygrometer automatically detects the humidity of the air and can independently determine whether to switch itself on or off to maintain the preset humidity levels.

The humidity can be adjusted by toggling the Settings button and each click will adjust the desired humidity in five percent accessions.

This dehumidifier was designed with convenience in mind and features user-friendly controls, a smart control display panel, programmable timer, washable filter, 7.4 pints water bucket, continuous draining options, and caster wheels.

The filter requires regular cleaning during operation. The filter can be easily popped out and cleaned with a vacuum or washed with warm water. This is simple and doesn’t take more than a few minutes.

The unit is relatively lightweight and is easily transportable around the home. Plus, it has a handle at the top for easy mobility.

The electronic touch-button controls are easy to operate, therefore you can hardly go wrong with the intuitive digital LED screen which clearly indicates the actual humidity and temperature of your room, as well as the working status of your unit.

The LED display control panel also has a button for speed control, a timer setting button, a function to automatically defrost, and a protection alarm with the water tank is full.

For those who’ve never owned a dehumidifier and don’t know how they operate, they work exactly as an air conditioner does.

Just like an air conditioner, a dehumidifier occasionally suffers from a build-up of ice or frost on the evaporator coils. Unfortunately, when this happens the dehumidifier is no longer usable.

The Inofia Dehumidifier has an auto-defrost feature, so when frost is detected the compressor of the machine automatically switches off. This is great because it prevents any more ice from building up.

The only thing that stays on is the fan, which constantly blows against the ice which causes it to melt. This dehumidifier has an automatic drainage pipe that has a length of about 2 meters.

If your grow tent is the basement, this is the perfect choice for you because the high potent pump compressor speedily removes water from the humid atmosphere.

The Inofia Dehumidifier has ultra-quiet technology and operates with little noise. By setting the timer function, you can set a time for the machine to shut down which provides efficiency and less power consumption.

The timer setting allows you to set the unit to run for a specific amount of time and shut-off automatically. Each click adds an hour to the shut-off time, which can be stacked until you reach the 24-hour limit.

You will also be able to see if the timer is on or off via the indicator light. If the water tank is full, it will automatically stop functioning and alert you with an alarm.

We’re confident that the impressive features of the Inofia Dehumidifier will provide you with the ultimate user experience while fitting within your budget!

The Inofia Dehumidifier will undoubtedly lower the humidity to your preferred level using the easy ‘one-click’ single button on the display screen which is really easy!

Some of the most common complaints of the hOmeLabs dehumidifier come from the water tank being relatively small compared to the size of the unit, overly loud running noises and cost.

Dehumidifiers; Buyers Guide

The size of your grow tent is the first thing you need to consider before buying a dehumidifier. A larger room will require more power and thus, bigger equipment whereas smaller rooms can be easily regulated with small appliances. It’s also important whether or not you want an appliance that only features a single dehumidifier function vs one that comes as a 4-1 and can be used as an alternative to save on space. As many 4-1 air conditioners will also act as a dehumidifier, heater, fan, etc.

Grow tents along with other tools are often used to provide an optimal environment for plant growth, that they would normally experience in their natural habitat. However, this isn’t always attainable and the air in a grow tent can become very humid when you don’t have full control over the environment, which is bad as it limits or even inhibits your plants ability to thrive and survive.

Additionally, high humidity levels may lead to mold, bud rot, and other nasty surprises that can pose potential harm to your cannabis crop’s health!

When in the earlier stages, marijuana plants love an environment with a higher humidity level than when they mature. A healthy humidity level facilitates optimal airflow and nutrient absorption in the plant as well as helping you enjoy maximum yield. The opposite is true for later stages of growth whereby lower humidity levels are normally necessary.


Dehumidifiers can play an integral part in any grow tent or grow room, and if your serious about controlling every aspect of your crops environment and producing the best yield possible, then investing in the best dehumidifier for grow tent is a must.

Without one, serious issues may arise that put an end to your crop before it’s even begun.

It doesn’t end there though, make sure if you do invest in a quality grow tent or grow room dehumidifier that you get your sizing, placement, and air flow correct, as these three things are just as important as the equipment itself for a successful crop.
