Axial Inline Fans are more ideally suited to inlet or circulation applications given their high-flow, low pressure characteristics.

Bring cooler air into the ground level (opposite corner to the extraction fan) of the grow tent or growroom area through a small amount of ducting.

The position promotes movement of air throughout the room which serves to eliminate hot spots and to maintain optimal air pressure inside the room or grow tent.

A small oscillating Wall Fan or Clip Fan should be used to mix the air as it moves through the grow room ensuring all areas receive sufficient fresh air for your plants.

The overall system should provide slightly greater extraction to ensure no unfiltered air escapes the room.
