Last Updated on January 7, 2022

Humidity can be considered as both blessings or a curse for your growing plants. Because the humidity level in a grow tent can both help or damage your plants. If you want to have pleasant and eye-catching plants, you must have to take care of the humidity level in your tent.

According to a standard calculation, your tent’s humidity level should be approximately 70%. If your tent gets higher humidity than this amount. Then, you have to lower the amount of humidity in your tent. Otherwise, you may have to face problems like slow growth, mildew, fungal growth, bud rot, mold and so on.

Today, I will talk about some simple steps following which you can easily make your tent’s humidity level lower.

How to Lower Humidity in Grow Tent

1. Water your plants in a moderate amount

Watering your plants in a moderate amount is one of the easiest ways following which you can make your tent’s humidity level lower. Because watering plants in an excessive amount can make the water damp or soggy. As a result, the soggy or damp water will leave a good amount of water in the propagation trays that will ultimately lead to raising the humidity level. So, you should water adequately to your plants. Not excessively.

2. Avoid any unnecessary water points in your tent

You should remove all extra water point from your growing tent. For this, look carefully around your tent whether there is anything like a container that holds water or not. If so, then you have to remove that. Because this water gets evaporated and as a result, the tent humidity is increased.

Apart from that, the stagnant water in your tent can turn into the ground for bacteria and fungi. As a result, your plant will be affected by both excessive humidity levels and diseases because of the dirty water. You can build a drainage system for removing extra water from your tent.

3. Use appropriate soils that have better water draining capability

Basically, there are three types of soil. They are clay, sandy and loam. Each type of soil has a different amount of water holding capabilities. Among the three types of soil, the clay soil has maximum water holding capacity and also does not drain at all. On the other hand, sandy soil is totally different as it has faster draining capabilities. Lastly, the loam soil stands between sand and clay soil.

So, as you can understand that the loam soil is the best option that you can pick. Because it has a moderate amount of water holding and draining capabilities. It does not drain either too fast or  late. So, you should go to the loam soil. What if you wish to drain more water? You can use sand soil. In this case, you have to keep your eyes on the nutrients.

4. Bringing a dehumidifier inside of your grow tent

Bringing a dehumidifier is considered the most effective way of dealing with the excessive amount of humidity. You might be confused about a dehumidifier if you are a newbie. Simply, the dehumidifier is a device that is designed for removing the excessive amount of moisture from the air.

However, after getting the dehumidifier, you should place the dehumidifier in the center of your tent. Without it, make sure that your dehumidifier has an automatic shut-off feature.

5. Never mix young and mature plants

Well, you are supposed to know that plants of different ages need different humidity. The matured plants have developed leaves. This kind of leaves has large stomata that used to release excessive water while respiration. This released water will make an impact on the young plants. They will suffer much because of increased humidity.

Without it, the growth of an adult and a young plant is not the same. So, it is better not to mix up the young and mature plants. Make sure that the plants you are growing in the tent are of the same age and growth.

6. Checking the density of plant

Plant density is an issue where you need to pay proper attention. This type of trick works better. You don’t need to pay any extra amount of money for that. Whatever, if your tent holds a high density of plants, the amount of released carbon dioxide will be higher.

The high amount of carbon dioxide will lead to high temperatures. As a consequence, the moisture will go higher and the humidity level will get increased. So, take care of this issue.

7. Creating holes for air

You can also make holes in your tent for flowing air. As you want to lower the humidity level, you should make the hole bigger so that the amount of air getting in is higher than the amount of air getting out.

8. Insulating and sealing your grow tent

Sealing and insulating your tent also works great to make your tent’s humidity level lower. For this, you can use foam insulation for making a skinny barrier between the grow tent and the outside environment.
