As for air exchange you will need an intake fan to bring fresh air in and an exhaust fan to eliminate stale air. Passive intake relies on passive airflow and negative pressure. The most common grow room systems use a combination of exhaust fans and ducts or pipes to maintain airflow.

The role of air circulation in cannabis growing air circulation in the growing space is key to a successful grow. My grow room has two windows which allow me to use one as an air intake and the other as an air exhaust.

Larger growing spaces or gardens with more grow lights would need multiple fans to regulate the temperature humidity and co 2 levels. Active intake instead of using fans to circulate air a passive intake grow room has ports or access points that allow air to naturally come into the grow space while an exhaust fan. There are two ways that you can bring air into your grow room referred to as passive intake or active intake. Either an intake fan that pulls air from an outside source or a passive exhaust system pulls in fresh air by forcing old air out through an exhaust duct.
