Grow tents are needed for the indoor cultivation of plants. But one critical aspect that should be of concern when growing plants indoors is the atmosphere.
If you do not want your plants to suffer from intense heat or humidity, you must ensure proper ventilation of the grow tent. It is an effective way to keep the indoor grow tent cool.
In this guide, I will walk you through how to set up a grow tent ventilation setup so that your plants get the right amount of heat, humidity, and carbon dioxide, among others.
But before we proceed, would you love to get a grow tent fan? You can check out the Hydrofarm ACDF8 Active Air Inline Fan.
Ultimately, the success of your plants depends on how well the grow tent is ventilated.
Here are some primary reasons why your gardening tent needs proper ventilation:
Lights emit heat naturally, which can alter the grow tent’s temperature.
You can eliminate excess heat from your grow tent through proper ventilation.
If you do not control humidity, your plants may likely not thrive.
Plants produce water vapor naturally, and this increases humidity. You can only control the humidity level through proper ventilation.
Gardeners are always worried about pests and diseases affecting their plants. But with proper air circulation, you will not have to worry about such.
CO2 is one of the critical ingredients for proper plant growth. Plants that grow outside access carbon dioxide naturally. However, in the grow tent, the levels of CO2 keep decreasing.
The ventilation will bring more carbon dioxide from the outside.
Plants that grow outdoors have their stems strengthened by strong stand winds. The air blown by the ventilation system will help the plants inside the tent stabilize their stems.
The process of setting up a tent is not easy. However, you can grow any crop anytime when you get it right.
Several things go into the setup process of the grow tent ventilation.
For instance, the essential bit of the ventilation system is having the fans and the carbon filter working for you inside the grow tent. Hence, it is crucial to have proper ducting to connect the filter and the fans.
When the fans work correctly, controlling the airflow and circulation becomes easy.
Here are some details you would need:
Using rope ratchets, hang the fans on the crossbar inside the tent. These will help in adjusting the accessories without affecting the plants.
Two types of fans can be used inside the grow tent as ventilation. They include:
Oscillating fans are cheap and effective. They are designed to circulate air around the plants and in the tent. The setup process of oscillating fans is relatively easy.
Depending on the grow tent size, you will need a number of them. When installing the fan, ensure that they are not directly facing the plants to avoid windburn, which can cause severe damage to the plants.

Ventilation systems use air extractors to extract air and bring fresh air. You should install the extractor fan on the crossbar and ensure that it runs once every 5 minutes, as this is the only way to guarantee proper air circulation inside the tent.
One of the best air extractors available on the market is AC Infinity CLOUDLINE S4.
The best way to have the ventilation set up is when setting up the grow tent. You need to check the manufacturer’s instructions as far as the setup of the growing tent goes.
Moreso, it is advisable to set up the ventilation during the grow tent assembly to prevent interference with plants.

You can bring air into the grow tent through the passive or active medium.
The passive intake fan method only supports the removal of air with no means of blowing air into the tent. It relies on the principle of negative pressure and passive airflow.
If you choose this method, you will need to create an artificial hole to allow air passively into the tent, enhance the fan’s effectiveness, and prevent it from overworking.
The hole should be about four times larger than the exhaust hole. This will give your ventilation great suction.
The active intake method absorbs air directly from the fan. This means that one fan blows air in, and another blows air out of the grow tent. In this case, the size of the intake hole is insignificant.
Find a ventilation system that effectively controls the humidity levels and prevents diseases. Lowering humidity levels is quite simple. You only need to push the humid air out using the exhaust fan. The dehumidifier is another important accessory you can choose inside the grow tent.
There are other instances when you may be forced to increase the humidity levels. You can do this by sealing the grow tent and switching off the exhaust fan. However, before doing this, ensure proper research to determine the humidity favorable for your plants.
Larger plants will produce more water vapor, so they may have to monitor the humidity levels more often.
The injection of carbon dioxide is essential for transpiration to take place. Unlike the plants on the outside farms, CO2 levels in growing tents seem too low; hence, the need for injection.
The proper injection of carbon dioxide requires that the tent be sealed thoroughly to ensure efficiency. CO2 is only effective when it is highly concentrated.
