Abstract: Apparatus for spraying atomized water for cooling golf green turf grass generally includes a chute having a circular intake attachable to a blower and exhaust having a generally rectangular perimeter with a sides contouring from the circular intake to the exhaust perimeter in order to provide a generally rectangular exhaust air flow. Vertically oriented linear arrays of water nozzle disposed on opposing sides of the exhaust perimeter are provided for limiting side way diffusion of the air exhaust from the chute. The nozzles are interconnected with a water supply through a pump.
