Best Dehumidifier For grow Tent: Round-Up Review 




First on the list is the Vremi 30-pint portable dehumidifier, this little powerhouse stands at 15.2” H x 10.2” L x 19.7” D and eliminates odor, moistness and other little nasties from the air, it’s consistently rated 4 stars and above and is one of Vremis most popular products. It features two modes, normal air CFM 129 (cubic feet per minute) and high air CFM 138 which maximizes moisture and odor removal. As the name suggests it holds 30 pints which is roughly 4 gallons and has a 3-liter tank capacity. It’s best used for areas no larger than 1000 SQ FT and can run on a 24hr cycle which automatically shuts off when the tank reaches capacity, or you can opt for manual mode simply by selecting one of Vremis user-friendly, easy to read controls positioned to the top of the unit. Portability wise the Vremi is light and portable enough for most users, with its built-in wheels and handholds to the sides.

As well as removing moisture from the air the Vremi comes with a removable filter that catches any undesirable particles, this is positioned to the back of the unit near the top. The tank of the Vremi is positioned to the bottom of the unit and can easily slide out for emptying. Another plus for the Vremi is the integrated drain outlet for continuous drainage, unfortunately, a hose is not supplied. Pricing for the Vremi dehumidifier models generally start around the $180 – $200 range.

Common problems that have been reported about the Vremi 30 pint portable dehumidifier normally come from the removable tank being difficult to reinsert and premature failure of the unit itself, don’t panic though, as Vremi is fairly quick in rectifying. All in all, the Vremi is a well made compact little dehumidifier that does the job fairly well.




Small but powerful, the Ivation 11 pint compact dehumidifier is ideal for the smallest of set-ups, measuring at 10″ × 9.6″ × 19.5″ The coverage of the Ivation is nowhere near the bigger dehumidifiers out there and is only suitable for rooms up to 216 SQ FT, but this is no bad thing if your grow set-up is only small. The control panel is to the top of the unit and is of a circular design, it incorporates a large easy to read LCD display and has multiple selectable functions including a 24hr timer, smart mode, fan speed etc, it also allows the user to adjust the humidity in 5% increments. Other bonuses of the Ivation come in the form of its built-in compressor which is rare for a unit this size, purifier for any unwanted odors and particles, and a drain outlet for continuous drainage (no hose included). As with many dehumidifiers that are smaller and provide less coverage, the price will always be lower and the Ivation is no exception to this, starting around the $150 range, which to be honest isn’t too bad.

Most reported problems of the Ivation 11 pint dehumidifier come in the form of functions not working properly, noise produced from the unit being overly loud and short lifespan of the device. 




Next in line and moving up in size is the hOmeLabs 70-pint dehumidifier, measuring at 15.4″ x 11″ x 24.3″ it’s ideal for any mid-large size grow rooms, covering a massive 4000 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.




Last but not least is the Costway portable dehumidifier, consistently rated 5 stars across its 3 models (30, 50 and 70 pint respectively) it seems to be hitting the right spot with many buyers. Height wise this particular model comes in at 15.5″(L) x 12.5″(W) x 20.5″(H) and coverage from the device is up to 3000 SQ FT and is capable of extracting up to 50 pints of moisture a day, with a water tank capacity of 8.5 pints which is not to shabby.

The controls of the Costway model range are normally positioned to the top of the unit, they feature a smooth, sleek looking digital display that has multiple functions, some of which are – a 24-hour on/off timer, 3-speed fan (High/Med/Low) child-lock and automatic shutoff when the bucket is almost full. Unlike the other dehumidifiers listed, portability wise the Costway model incorporates a pull-out handle to the top of the device instead of handholds to the sides and your standard inbuilt wheels to the bottom. There’s a washable filter as standard positioned to the top, and a removable water tank positioned at the front of the device to the bottom. Price wise, Costway dehumidifiers normally start from $150 range all the way up to the $200 range, not the cheapest but the not the most expensive either.

Generally, the feedback from buyers of the Costway dehumidifier are all positive and faults seem none existent, as above, they consistently rate at 5 stars across the board, so you should be in relatively safe hands when buying a Costway dehumidifier.
