How To Lower Humidity In Grow Tent : The Best Way

When it comes to grow tents, there are lots of aspects that play a major role in guaranteeing the best plant growth. For instance, you have to invest in lighting, the right air conditioning, and most importantly, the perfect humidity control.

However, rarely do most indoor growers, especially the novice and newbies, ever take the issue on humidity seriously. With the wrong humidity level for your grow tent, you risk having to deal with bud rot or dried up plants.

Basically, there’s so many things most indoors growers don’t know about humidity. For example, did you know that humidity changes whenever you’ve turned on the lights of your grow tent?

Also, did you know that temperature has an inverse relationship with humidity? That is, when temperatures are high, the percentage of relative humidity in a grow tent decreases. Did you know that? You probably didn’t.

Yeah, I know, this is too much 😕😕 and very confusing!

Don’t worry though, coz by the time you’re done reading this article, things will be crystal clear.

Let’s have a look at a few tips on how to cool a grow tent and keep it well humidified

Make Sure Your Grow Tent Is Well Insulated

This comes as a no surprise. You need to have a best hydroponic grow tent that’s perfectly insulated. If you DIYed your own grow tent, then it’s best to recheck everything once in a while just to make sure the walls are adequately sealed.

You gotta make sure you do occasional maintenance checkups. The same goes for grow tents you’ve bought online.

It’s important to note the differences in grow tents, whereby some are more effective than others. However, when it comes to insulations, most grow tents are peas in a pod and there isn’t much of a difference.

Still, you gotta check if the grow tent has the right reflective materials. I particularly prefer tents insulated with waterproof mylar, which usually enhances the reflective effects. If you’d like to replace your grow tent, then I’d advise trying the BloomGrowFull SpetrumTent – it’s really worth it.

In addition to checking the possibility of an insulation fault with your grow, you can also use foam insulation or any other material to create some kind of barrier between the grow room and the outside environment. If it’s near a window, that’s something you gotta take into consideration.

Checkout the Grow Room Temperature

Indoor grow rooms are usually meant to get rid of the “weather and climate” effects such that you don’t have to worry about seasons. However, without noting and controlling the temperature, then this functionality of grow tents is pointless.

So, how do you check and control room temperature?

Well, the best way is to use the likes of VIVOSUN DigitalThermometer, which is a reliable gadget in making sure you always have the right temperature for your grow tent. Although some thermometers may dabble as humidifiers, it’s recommendable to have both gadgets.

Use the Right Humidifier for Your Grow Room

Most folks tend to simply go to their local store and get a cheap knockoff of a humidifier. If that’s you, then you better buy something of high quality.

But then again, it doesn’t necessarily mean that once you’ve bought a high-end humidifier for your grow room, then everything is okay. Well, sorry to bust your bubble but it’s more than that. For instance, you gotta take the size of the dehumidifier into consideration.

If you’ve got a large and spacious grow tent, then it’s advisable to have several humidifiers installed. Make sure to set the humidifiers such that if one stops working, the rest resume working smoothly.

From the reviews we checked out, you can always go with the Honeywell HCM350W Humidifier, which has the best feedbacks from expert indoor growers.

Still, if you find the humidifier is way out of your price range, then the SmartDevil Small Humidifier is perfect for you. It’s pocket friendly.

Make Sure There’s Proper Air Movement

When you’ve got a highly humid grow tent, it means that the air is holding more water. It also means that the air surrounding it is heavier; thereby, the humid air from the grow tent rises towards the ceiling.

The result of such a movement is that the CO2  remains at the bottom of the tent, thus causing an imbalance of some sort. Therefore, you have to take care of such a situation.

Most indoor gardeners usually assume that oscillating fans is sufficient; but it isn’t. In fact, the fans only reduce the tent’s temperature but fails at guaranteeing a proper air circulation.

So, what’s the best solution? Advisably, please get a floor fan. I’d recommend a pair of them. And since most of them are costly, try and buy something that’s gonna cost you an arm and a leg. The LaskoQuickMountFloor Fan is a great option.

Check Out Your Drainage

If there’s a common that most indoor growers tend to overlook is the formation of standing water within the grow tent. It might be a small patch of water, but it makes a huge difference.

The standing water not only increases humidity in your grow tent, but it also acts as a breeding ground for bacteria. Such formation of puddles of water is particularly common with hydroponic setups (where there’s no soil).

Therefore, make sure you’ve got a proper drainage system for your grow room.

Final Thoughts

It is common for indoor growers to assume that they’ve perfected the issue of humidity for their grow tent. This is usually disapproved when harvesting the plants, whereby some plants don’t come out as expected. They are either dried up or have bud rot.

I hope this guide on how to lower humidity in grow tent is helpful enough. That is, for maximum yield, humidity needs to be in an appropriate level, at all times. And that’s why you needan effective humidifier, a pair of floor fans, and a thermometer.
