Abstract: Disclosed is a ventilation system which provides for the removal of the air accumulated on the grass field surface from the grass by creating a sweeping effect by a fan in the playing fields such as stadiums with low air circulation and which provides the fresh air to be distributed onto the grass in a homogeneous manner. The distinctive feature of the ventilation system is that it lifts the fans providing the air circulation onto the field, that it can provide the air in a controlled manner without causing harm to the grass and facilitates the assembly and disassembly operation. In addition to that, it is mountable to an existing Growlight and/or artificial daylight unit.
