hOmeLabs Dehumidifier

The hOmeLabs dehumidifier, measuring at 15.4″ x 11″ x 24.3″ it’s ideal for any mid-large size grow rooms, covering a massive 4500 SQ FT…Make no mistake about it, this is a large but surprisingly compact and sleek looking dehumidifier.

This particular hOmeLabs model removes up to 70 pints of moisture from the air per day, which is approximately 9 gallons worth, that’s an impressive amount even if we do say so ourselves.

As with most dehumidifiers, the controls are positioned to the top of the unit in the hOmeLabs model. They’re easy enough to use, but for a model this big the LCD display and buttons could be a little bigger.

The hOmeLabs dehumidifier comes with a simple array of options, such as auto shut-off, defrost, restart, and turbo mode. With in-built wheels and handholds to the sides, portability is relatively easy.

As well as the above a 24hr timer, easy to clean filter and manual drain access is also included. Emptying the collected moisture comes in the form of the 1.6 gallon (6 liter) water tank that is located to the bottom of the device.

hOmeLabs dehumidifiers are quite reasonably priced compared to others, for the smaller 6-gallon dehumidifier you can generally find it for around the $160 range, the bigger 9-gallon model is superbly priced starting around the $190 range, let’s be honest, for a dehumidifier that big you can’t really grumble at that price.

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.

But, if any problems do occur with the hOmeLabs dehumidifier, there’s no need to panic as most models come with a 2-year warranty and further 6 months if you sign up online through their website.

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.
