We use these flat head spray nozzles that are specially designed for outdoor use. They deliver a pattern of water that is almost perfectly horizontal. The water is atomized, but only to a point. What makes these nozzles unique is that the droplets of water are tiny, yet just large enough to not be easily carried by the wind. Other nozzles don’t work because all of the water just blows away.
If all you need are Flat Head Spray Nozzles we sell them stand alone as a package of five which includes the nozzle in the picture with the legs and the tubing.
