A misting system should have pressure between 20-30 psi. If the pressure is too high, it can cause water droplets to be blown off of the plants and onto people or objects below. If the pressure is too low, the system will not be effective in distributing water evenly.

Misting systems are used to provide a fine mist of water to help cool and moisten the air. The amount of pressure needed in a misting system will vary depending on the system's design and the specifics of the installation. In general, it is recommended that the pressure be set between 25-40 psi. If the pressure is set too low, insufficient water will be sprayed and the system will not work properly. If the pressure is set too high, there is a danger of hose rupture or other equipment damage.
