Ideal Temp And Humidity For Grow Tent | Advice For Beginners

Last Updated On: September 10, 2021

When you think to grow something in a tent, you might be interested to know the ideal temp and humidity for grow tent. It is tough to keep for grow tent, isn’t it?

I will help you by providing some information about how you can set up an ideal temp for grow Tent, trust me.

In this article, I will describe how to control the temperature of your grow tent. You will be able to look after your grow tent yourself.

During the pandemic situation, I was very bored living in the house, needed to close to nature. I went to one of my friend’s houses to see his grow tent. I expressed my interest to have one like this and he shared his experience with me.

What Temperature And Humidity Should Grow A Tent?

Grow tent’s temperature and humidity rely on relative temperature. Soothing nature encourages plant growth. Cool temperature follows nature, even if it is hot during the day, try to keep cool the temperature for plant growth. The perfect temperature is for lights on 66-77 F and lights off 8-9 F.

What Are Temperature And Humidity?

When you want to build a grow tent, you must know the temperature and humidity. Temperature is a type of measurement that controls the balance of the environment. The ideal temperature is based on the type of plant. When the temperature of the grow tent is high, the transport of water vapor is affected and the tree may become weak. On the contrary, if less, the tree dies.

The most important thing to keep in mind here is how much water vapor retention capacity will be achieved.

If the plant dries out too much, it will lose its functionality and productivity will decrease. Four elements of the environment, such as temperature, light, ventilation, and irrigation, play an active role in increasing humidity.

What Is Relative Humidity?

Ideal temp and humidity for grow tent are related to relative humidity. Relative temperature is the percent of water vapor in the air. The growth of the plant is affected by the relative temperature. Note that plants can retain 5% water vapor and the remaining 95% return to nature. It can control the humidity of the air due to the presence of water vapor. This allows the plants to stay cool and absorb nutrients.


What Is The Ideal Temp And Humidity For Grow Tent?


Best Temperature For Vegetative Stage In A Grow Tent

The perfect temperature for the vegetative stage in grow tent is 86 Fahrenheit in the daytime. During the nighttime, cool down the temperature at 68 to 75 Fahrenheit.

What Temperature Should my Grow Tent Be During Flowering?

In the case of flowers, the temperature is more or less it depends on the time. In this case, the temperature should be kept below 5 centigrade or 77F at nighttime. During the day, the perfect range must 20-25 centigrade but it is important to make sure that is getting the right decoration.

Temp And Humidity Control For Grow Tent

Some tools are used to grow tent temperature and humidity control growing plants perfectly and plants grow properly. If it becomes uncontrolled, the plants will ruin. So these four items must be considered for grow tent:

  • Control of the Co2 for ventilation must be maintained so that the water molecules are attached as the air rises
  • To free ventilation, the outside ventilation process has to be done through indoor air exhaust. For controlling this by using a simple timer
  • To keep the right temperature in a grow tent, air conditioning can control the system because the uses of light can control by air conditioning. Depending on the size of the grow tent, the temperature can be kept at 70-80 f temperature
  • The dehumidifier can ensure the water circulation of the seedlings

Grow Tent Temp and Humidity Monitor

It is important to observe the level of the plants for their growth and flowering. That’s why some things need to be monitored constantly for the temp and humidity sensor for grow tent

  • Keep the right amount of humidity level. Need 40%-55% for plants humidity and flower 30%-55% humidity. But the Ideal amount is 40%-45%.
  • Each level need to be monitored by a Hydrometer 
  • Monitoring ventilation

Too Low Humidity In A Grow Tent?

Due to low humidity, the seedlings grow weak and delay the growth of seedlings.

How To Adjust Temperature & Humidity

  • Refrain from giving extra water

Excessive watering should be avoided as this can lead to soggy soil and increased moisture.

  • Determine the density

The size of the tent depends on the number of trees so that water vapor does not get trapped and can circulate air.

  • Draining the water

When water is not drained in the growth tent, bacteria are formed under the influence of molecular oxygen, so you need to keep the right humidity. 

  • Use A Grow Tent Dehumidifier To Decrease Moisture

It is an easy way to monitor how much water should collect in a grow tent is to use a dehumidifier. As a result, with the help of a timer, water holding capacity can be ensured very easily. 

Too High Humidity in a Grow Tent?

It is not good too high for a grow tent. High humidity prevents the growth of seedlings in wet areas. Learn why Tents get wet inside.

  • In many cases, if the humidity is high, the air cannot circulate
  • Extremely high temperatures disrupt the heath quality of the seedlings
  • The overall plant metabolism rate will decrease
  • Inhibiting photosynthesis in plants

How Do You Keep Humidity High in a Grow Tent?

By the following instructions, the humidity will increase for grow tent:

  • Small plants accept their Co2 & water from large plants. Large and small seedlings need to be combined for respiration to increase production. 
  • Use Of Propagators
  • Build Own Propagation Set-Up by a grow tent humidifier 
  • Remove Half Of Fluorescent Lights
  • Set Extraction Fan Setting To Minimum to ensure relative humidity
  • Use Of Water Spray Bottle

Why is There Condensation in Grow Tent?

Consideration in the grow tent can occur fast because it raises the air temperature if the relative temperature rises. In addition, the surface temperature of the leaves increases the concentration of the water vapor inside the seedlings.

How To Keep Grow Tent Cool In The Summer?

There is some information to keep a cool grow tent in summer. This use:

  • Use LED grow light
  • Use exhaust fan
  • Use a swamp cooler in the tent
  • Use an air conditioner to the tent
  • Maintain lighting at night

How To Lower Humidity In Grow Tent? Read this article.

Final Word

So in this overall context, we can say that ideal temp and humidity for grow tent are very important for growing a tent otherwise the growth of plants will be affected. For this, some tools must be used for controlling the temperature. For this, necessary equipment like light, exhaust fan, air conditioner, and ventilation is more effective for the care of the executor.
