So, if you somehow cross this threshold limit, try finding out where the extra moisture is coming from. 

How Does Excessive Humidity Affect Plants? 

You might have learned from different people that plants love high humidity. No doubt that’s a fact.

Here, read below about why more than enough humidity affects the plantation:

  • Humidity creates a perfect environment for molds and bacteria that can harm your plants.
  • The high amount of moisture in the air can block the pores of plants and prevent them from performing transpiration.
  • Moisture also welcomes pests and diseases.
  • Humidity slows down your plant’s nutrient intake.
  • If you have planted flowering plants, they would suffer from bud rot due to excess moisture.
  • All this would collectively minimize your plant yield.

According to the research, vegging plants need 50%-70% humidity because they can take up water from their roots. Flowering plants need 40%-50% humidity for a healthy environment to breathe.

Understanding the consequences of high humidity, you are also required to save your plants by understanding how you would maintain the low levels of humidity.

10+ Ways To Lower Humidity In Grow Tent Or Grow Room 

Here are some convenient ways to help you improve the humidity of your plantation environment.

Avoid overwatering your plants

Watering plants already increases the humidity of the air around the plant. You have more of these plants, which leads to an overall increase in the air moisture that would further start damaging the crop. Moreover, the soil would leave extra water in the water trays which would again lead to the humidity rise.

Check the density of your plant

Plants release carbon dioxide into the air which raises the air temperature in your grow tent. This leads to the building up of moisture. You can simply remove some of the plants out of your grow tent. If you can’t do that, simply remove those with bigger leaves.

Make use of a dehumidifier in your grow tent

Buy it and install it inside your grow tent. When the moisture in the air gets excessive, the dehumidifier removes the extra humidity. Make sure your humidifier is connected to an outlet drain or it would rather increase the moisture. 

Don’t let water stagnate

You, as a responsible indoor grower, have to ensure that your grow tent has a proper drainage system for the flow of water which would disallow any remaining water to stagnate inside. If any water stands inside your tent, it would mix as a vapor and increase humidity. 

Ventilate your tent properly

Install small fans in your growth tent that would work as exhausts for any excess moisture and would also prevent extra water in the soil from standing in the water tray. 

Create air holes

Making holes inside your tent would again maintain the flow of air that would keep the atmosphere inside the growth tent healthy and fresh. To decrease humidity, try making wider holes to ensure more inlet of air inside the tent. 

Install an Air Conditioner

We already know that the air conditioner compresses the air and removes moisture from the air which ultimately lowers the humidity. All the extra water will be removed through the condenser inside the AC. 

Insulate and seal your tent

This method would prevent any external factors from altering the relative humidity of your grow tent. Try using foams for insulating your tent walls to create a thick border between the inside and the outside environment.

Use absorbent soil

If you are an indoor planter, you must know about different types of soil. I would recommend using sandy soil that lowers the evaporation rate and does not let any water in the solid mix up in the atmosphere. 

Cut down extra leaves

Usually, the plants with bigger leaves can cause increasing humidity. Try chopping off any excess and big leaves that would help maintain the moisture in the air.

Use grow tools wisely

Grow tools and equipment like grow lights also increase the temperature of the air around it which automatically increases the humidity in the air. Try turning off the grow lights if you feel your grow tent has become warm already.
