Good ventilation in a grow room or grow tent is crucial to the development of the plants and the cooling of the environment & equipment. The air inside the tent must be constantly moved and renewed, the best tool for the job is an extractor fan (Inline fan) placed inside the tent.
Fans actively pull the air out of the tent creating negative pressure (the walls of the tent are pulled towards the inside of the tent), forcing new fresh air in the tent and assuring a good air flow.
We recommend higher output inline fans if you chose to grow with HID grow lights, they require more cooling than LED grow lights.
