What is Airflow?

Airflow in terms of indoor growing simply refers to a fan or system that imitates natural outdoor conditions, keeping plants healthy and pests away. Indoor cannabis cultivation necessitates a natural atmosphere for plants to thrive. Creating, automating, and maintaining proper ventilation is a factor that shouldn’t be ignored when growing indoors.

Using Proper Ventilation

Simulating outdoor environments has various uses. The natural resistance of airflow develops stems, same as lifting weights strengthens our muscles. The extra structural strength helps plants handle the intensive flowering growth stage.

Ventilation reduces humidity, which breeds mould and fungi.

Basic Airflow

Many options exist for creating ventilation in your indoor grow. Several factors influence the selection of a grow system. Price, grow space layout/design, odour concerns, etc.

The simplest and most cost-effective method is to use many fans in the indoor grow area. Small oscillating fans pointed at the canopy can help. Adjustable fans are also great options.

Establishing an exhaust system is another fantastic way to keep the air flowing and bring in fresh air. Stale air is moved out when using fans and new is brought in with Co2.

Construct your indoor marijuana grow with extraction in mind. Because warm air rises, the extractor should be towards the ceiling, but the air intake ought to be low to the ground. Indoor cannabis grows commonly employ carbon filters to filter undesirable odours, keeping your operation inconspicuous.


Smart grows automate airflow. A smart control feature in your exhaust system can be set to turn ventilation on or off based on VPD or temperature. It requires some trial and error, but once it’s dialled in, it’s just a click of a button to use, manage and maintain. Using an automated system that gives customer assistance is a plus.
