What are misting systems in a greenhouse?
Misting systems are used to deliver a fine spray of water into the greenhouse airspace in order to provide some relief to the plants in very hot and/or dry conditions. Most of the misting systems operate under a pressure between 250 kPa and 300 kPa. The droplets of water are in the range of 100 to 200 microns. A droplet of this size is considered too large to be completely evaporated. So it falls very quickly by wetting the crop and the floor of the greenhouse.
Though misting systems have a benefit of cooling, a wet canopy will lead to an increase in diseases and damage of fruits. A wet floor is always a safety risk to people in the greenhouse.
