Where Should I Use the Humidifier? Inside or Outside Grow Tent? 

You can use a humidifier both inside and outside the grow tent. However, it is recommended that you put it a few feet from your plants. And, if possible, in the middle of the room.

If you put it too close to the plants, it could wet the soil and leaves. Mold and fungus can grow on leaves that have too much water on them.

You can also put it outside grow tent. In this case, you need to place it a few feet away from the intake fan.

So, there are no big drops of water in the air. It simply circulates humid air within the room, which is pulled into the tent.

Things to Consider When Choosing a Humidifier 

Choosing a humidifier inside your outside your grow tent can be quite challenging. You may get overwhelmed with what to choose for your tent. 

Stop worrying, everything will be handled properly. Here are the most important criteria to keep in mind while selecting a tent humidifier.

Room Size:

Here is a chart for you to understand which type of humidifier you will need for your room

Small Humidifiers up to 300 sq. ft 
Medium Humidifiers 350-500 sq. ft 
Large Humidifiers 550-1000 sq. ft 

So if you have a small room, you can check out the MOVTIP Mini Humidifier. You can find it on amazon. It has an auto adjustable timer and multiple spray modes. But if you have a big room, you need large humidifiers. In this case, the Tower Humidifier is a good choice. It can cover upto 1000 sq feet of area. You can get it from amazon.

A small tip-  small humidifier should target 50% relative humidity.

Yield and Growth Rate:

While harvesting, you should focus on getting better plant growth and yield rate from a grow tent of 5×10 and others.

Setting up the humidifier inside the grow tent allows the plants to absorb vapor easily. This also creates an ideal environment for the plants. 

On the other hand, Setting up the humidifier outside the tent doesn’t have this facility. You need to set up intake systems manually. Hence, a slower growth and yield rate will be seen.

Thus, setting up a humidifier inside the grow tent will allow for better growth & yield rate. 

Overall Cost: 

One of the major factors while setting up a humidifier is the cost. Setting up a humidifier inside the room may sound cheap. But there is a catch. 

Each time you set up a new grow tent will require another humidifier which adds up to the overall cost. This might not seem cost-effective in the long run.

On the other hand, setting up a humidifier outside the grow tent will require a larger unit. In this case, it will cost more than the inside setup. 

However, setting up the humidifier outside the tent gives you full room coverage. Hence, you won’t need to set up a new one when placing a new grow tent. 

Temperature and Warmth: 

This solely depends on the outdoor climate. You should consider the yearly environment as the humidifier needs external air to sustain airflow. 

You need a cool-mist humidifier if you live in a hot and dry climate. IN that case, the Megpad Cool Mist Mini Humidifier is a good choice.

Conversely, if the environment is cold year-round, you will need a warm mist humidifier.

Mineral Dust:

Your humidifier’s performance will vary depending on the mineral dust you choose to use. It is as important as honey & molasses for the plant.

Use an evaporative humidifier if the air is too dusty or has too many germs to breathe comfortably. These impurities will be eliminated before the water is evaporated and released.

If you don’t have to deal with this problem, then any of the other humidifiers is probably better.

Humidifier Inside or Outside Grow Tent: Final Verdict

Setting up a humidifier inside the grow tent gives you a better production & yield rate. But if you need to place a new grow tent, the cost goes up. 

Setting up a humidifier outside requires a larger humidifier considering the room space.

But, in the long run, the cost will be lesser if you place new grow tents.

Considering all the factors, set the humidifier inside to do small-scale harvesting only.

But if you plan to grow your harvesting, setting it outside will be the wise decision.

Frequently Asked Questions (FAQs)

Here are some of the frequent queries and replies for you-

How far away should I place my humidifier from a plant? 

You should place your humidifier four to six feet away from your plants. This allows the plants to breathe comfortably and absorb water vapors. Therefore, the plant does not get wet or saggy. If your humidifier has a hose, do use that. It helps the plant absorb moisture easily.

Is a Cool mist humidifier good for plants? 

Yes, cool mist humidifiers are perfectly good for plants. However, there are factors to consider while using a humidifier. If you are living in a colder area, you might not be needing a cool-mist humidifier. Also, the cool-mist humidifier is prone to mold growth. Do keep an eye on that.

What should I do if my hygrometer is not working suddenly?

If your hygrometer stops working suddenly, you can use the ice cube test. Take a glass and fill it with ice cubes. If there is condensation on the glass body after 10 mins, the humidity is high. Otherwise, the humidity will be lower.
