Selection of the Best Dehumidifier
How to Buy the Best Grow Room Dehumidifier?
The above guide discusses the individual features and functionality of the best dehumidifier for indoor growing. Therefore, this buying guide includes the necessary features you should look for while buying the best dehumidifier for grow room.
First, you need to measure the total area of your grow room and multiply it by 0.623 to estimate the weekly water requirement in gallons. Next, you can easily convert it to daily water requirement and convert the gallons to pints by multiplying it by eight to calculate dehumidifier size.
For instance, one cannabis plant needs 1.4 pints of water daily, which means the dehumidifier needs to extract moisture from the grow tent.
You should check the noise levels mentioned in the box before buying a dehumidifier. It’s better to select a dehumidifier with a motor that ensures noiseless operations. As a result, it won’t disturb you and your plants in the grow room.
It’s better to confirm the Energy Star certification before selecting a dehumidifier for the grow room. This certificate ensures that the Energy star dehumidifier for grow tent effectively minimizes energy consumption, thus saving your electricity bill.
It should be easy for you to remove the air filters from the dehumidifier and wash them thoroughly. An air filter plays a make-or-break role in the performance of a dehumidifier by removing the dust, odors, molds, and other bacterial or fungal microbes from the air.
That’s why you need to wash the air filters periodically else they may get clogged.
A dehumidifier for grow tent should include caster wheels or handles to facilitate mobility.

Do You Need a Dehumidifier for a Grow Room?
Without any second thought, yes. It’s a very challenging task to maintain a healthy humidity level within a grow room. It’s because the moisture levels in the grow room significantly vary as the plants get water, breath, and perspire.
Furthermore, if the humidity level goes beyond a certain threshold, the leaves absorb moisture from the air. Hence, it may severely affect plants’ nutrient intake from the roots.
Conversely, if the humidity level is low, you need to water the plants more.
That’s why you need to install a dehumidifier that automatically regulates the moisture levels in your grow tent.
How Big of a Grow Tent Dehumidifier Do I Need?
You should select a dehumidifier according to the size of your tent. Moreover, a 4 x 4 grow room requires humidity levels of 40 percent relative humidity, while a minimum of 65 percent RH is necessary for a 5 x 5 grow tent.
The formula for selecting a grow room dehumidifier has been discussed in detail in the buying guide.
However, a dehumidifier can make the grow room hotter because of the operational motor. That’s why it’s better to buy a big dehumidifier that doesn’t run for a longer time. Besides, it’s necessary to enhance ventilation inside a grow room to reduce the temperature.
How Frequently Should You Run Tent Dehumidifiers?
The good news is that the latest models feature controls to adjust the humidity level within the grow tent by setting a target level. This way, you can program the timer so the dehumidifier runs for the specified duration and automatically turns off.
Lastly, the dehumidifier automatically turns off if the water bucket becomes full. That’s why you should empty the bucket frequently if you don’t want to turn off the dehumidifier.
Where Should You Place Tent Dehumidifiers in a Grow Room?
It’s recommended to place the dehumidifier in a dry location on the grow tent floor without any water overflow. One crucial point to consider is not to position the fan directly towards the plants; instead, the fan should circulate the dried air around.
The dehumidifier efficiency reduces if you place it on a height. It’s because the dry air rises removed from the tent quickly via the exhaust pipe. That’s why you should place the dehumidifier on the floor instead of a stool.
Wrapping up with the Top Dehumidifier for Grow Tent
It’s a challenging yet rewarding task to cultivate plants in a grow tent. That’s why you should buy premium-quality accessories such as grow tent dehumidifiers to facilitate the growth of the crops.
Besides removing the excess humidity from the air, a dehumidifier also helps prevent mold and powdery mildew growth. It means your cannabis plants can breathe in clean, pure, and dry air.
Lastly, a dehumidifier is necessary if you live in high moisture environments or tropical areas with constant rains.
