Larger growing spaces or gardens with more grow lights would need multiple fans to regulate the temperature humidity and co 2 levels. Using motorized fans for both the intake and the exhaust is common in medium sized grow rooms. For grow spaces higher than 8 8 feet or so use an active air intake fan for grow room to keep up with the wind pressure and air supply. My grow room has two windows which allow me to use one as an air intake and the other as an air exhaust.

Passive intake relies on passive airflow and negative pressure. Check our recent buying guide about how to use ozone generator in grow room use a centrifugal fan. Also learn how to set up an exhaust fan in grow room for maximum efficiency. Open loop grow rooms consistently provide fresh air to the plants in one of two ways.

In this type of set up the fans work together to evacuate air within the grow space and replenish it with fresh air. Anything from a small hole or gap under a door should be enough to let in ample fresh air. That said normally one fan is enough as you can use it both for intake and exhaust purposes just by turning it around. Fans within the grow area prevent hot or humid patches.

The two things every grow room needs are an air intake to draw in fresh air with normal atmospheric levels of co2 and air exhaust to vent out hot oxygen rich air. Temperature humidity an exhaust system helps control the temperature and humidity levels in the grow area by venting out hot and humid air and replacing it with fresh air. A grow room ventilation is a system that ensures a continuous flow of air between the outside world and the indoor grow area. To make sure there is plenty of incoming air to work with your exhaust fan an intake port must be installed in your grow room.

Some people drill a hole to create an intake port in the grow room. 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. With this grow room ventilation system you have a fan blowing air out but no fan blowing air in.
