Just like humans cannot live without air, your plants need a constant supply of fresh air for their survival. As indoor plants, they need fresh air to support their photosynthesis and respiration in a closed space. In addition, indoor humidity and heat conditions are quite different from those outside, and these problems need to be resolved through proper ventilation.

In this article, Spider Farmer will provide you with some suggestions to help you better ventilate your grow tent!

Why Is Grow Tent Ventilation Important?

Keep Proper Co2 Levels

Growers who have understood the basic rules of plant growth should know what carbon dioxide means for plant growth. They need to inhale carbon dioxide to complete photosynthesis and respiration, and being in a closed space for a long time will inevitably lead to less and less carbon dioxide content. Therefore, in order to maintain the carbon dioxide level in the grow tent, we need to supply the plants with a steady stream of fresh air to remove old air, so as to achieve the effect of increasing production.

Heat Management

Indoor growth is often accompanied by the use of grow lights, and grow lights usually emit some heat. LED grow lights are okay to a certain extent but grow lights such as metal halides, and HPS brings more heat. Furthermore, indoor ventilation is even more essential in a country with a hot climate all year round like Australia.

Humidity Management

In addition to controlling the heat level in the grow tent, we also need to pay attention to the humidity level. If the humidity is too high in grow tent, it is quite easy to cause the occurrence of diseases and insect pests, as well as the growth of mold. A good ventilation system can absorb some of the water released during plant transpiration, allowing your plants to absorb more water and absorb nutrients through the roots, thereby promoting growth.

Pest Control

Mold and fungi aren’t the only life forms growers need to be wary of. You’ll also need to protect your plants from pests that can thrive in stagnant air and moist topsoil. For example, spider mites and fungal gnats have difficulty flying in well-ventilated areas. This means your plants are a lot safer away from them when you have the right ventilation kit.

Tools Needed for Grow Tent Ventilation and How to Ventilate

Inline Duct Fan

The professional inline duct fan is definitely a good helper for indoor ventilation, it brings fresh air and carbon dioxide, removes odors, and reduces heat and humidity to plants by delivering powerful airflow to the grow tent.

Well, before choosing the inline duct fan you need to know the amount of ventilation your grow room requires, which is also called CFM. You can use this formula to calculate: Grow tent volume (in feet) x 1.2(no. of 30-degree bends) x 1.6(no. of 90-degree bends) x 1.6 x 1.2 x 1.5 = required fan CFM. After calculating the number, the CFM of the inline duct fan you want to choose should be greater than the number you calculated. Spider Farmer provides you with two different CFM volumes (205CFM and 402CFM) inline duct fans for you to choose from, continuously providing strong airflow to your grow tent.

Duct Tube

If you are using an inline duct fan in your grow tent ventilation system, then you will need a duct tube as well. These tubes will act as channels for the inline duct fan to exhaust the air, which is a must for indoor ventilation. They are usually made of aluminum, and the length can be adjusted according to your own needs, which is flexible and convenient to use.

When setting up your duct tube, you need to take care to try to keep the tube path as short and straight as possible for air to leave the grow tent. That is to say, the longer and more circuitous your path is, the less efficient your ventilation system will be.

Duct tubes of Spider Farmer are made of high-quality aluminum and PVC, with a double-layer design, high quality but low price, safe and durable. Built-in steel wire ensures its long-lasting performance, and you can extend the length according to your needs.

Carbon Filter

To prevent odors from spreading to other spaces in your grow space, you’ll need a carbon filter. It is also known as a carbon scrubber, this tool acts as a treatment for odors, neutralizing odors, and they are usually attached to the end of duct fans or tent ducts.

Spider Farmer’s carbon filter adopts RC412 activated carbon, which can achieve excellent odor control and purification effects. In addition, it comes with a pre-filter to help capture large particles of dust and prolong the carbon filter life.
