In order to achieve the correct RH and temperature, it is not enough to just spray as much water as possible. The quality and thereby the effectiveness of the spray is equally important.
As proven by the literature, you can only truely speak of fog when water is sprayed under high pressure.
Because of the high pressure of 105bar (1500PSI) and the specially designed nozzle the spray is optimized to create a fog that does not condense on to the plants, but completely evaporates before it reaches the plants. The drip-size of 5-10 microns causes a raise of the humidity and a strong cooling effect.
