Aug 3, 2021 · It mostly comes down to droplet size: Fogging pumps produce ultra-small droplets, approximately 1–10 microns. Misting pumps produce slightly larger droplet sizes, approximately 10–100 microns. Because fog has smaller droplets, it basically floats into the air and randomly settles on surfaces without rhyme or reason.

The humidity in the air affects the evapotranspiration rate from the leaf surfaces. To get good propagation, a balance between humidity and transpiration is needed to allow water and nutrient uptake without excess dehydration. In a crop with a dense foliage canopy and without much air movement, a boundary layer of moisture approaching saturation de...
Several methods are used to produce fog. A typical system uses a high pressure pump, distribution piping and nozzles that break the water stream into very fine droplets. Piston pumps are needed to develop the 800 to 1200 psi pressure to get the 10 to 20 micron size droplets. Most systems available from irrigation equipment suppliers and labeled as ...
A mist system contains piping, nozzles, filter, pressure regulator, solenoid valve and timer or controller. Several types of nozzles are available that develop mist size droplets. These include the deflector or impingement type which operates at 30 - 60 psi water pressure. A leak prevention device (LPD) is frequently added to eliminate dripping. A ...
Mar 9, 2011 · The particle size typically used in high pressure greenhouse fog systems is about 10 microns. Mist consists of particles from 50 to 100 microns. As a comparison, human hair is about 0.004 inches in diameter or about 100 microns. Breaking 1 gallon of water into 50 micron droplets produces about 68 billion droplets of fog.
May 30, 2018 · The particle size typically used in high pressure greenhouse fog systems is about 10 microns. Mist, on the other hand, is particles from 50 to 100 microns. As a comparison, human hair is about 0.004” diameter that equals 100 microns. Breaking one gallon of water into 50-micron droplets will produce about 68 billion droplets of fog.
What is the micron size of the fog particles/droplets? Unlike most fogging and misting systems, Lafferty Foggers are adjustable! While each fogger class (612, 633, 305, 455) produces a different type of fog, the particle size and output wetness can be reduced in the field.
Some systems claim to produce fog or mist, using mains water pressure in the region of 6 Bar or even 20 Bar. This is not possible. These systems are really sprinklers and will generally wet an area rather than fog it. Droplet sizes are often in excess of 100 microns and are more like drizzly rain than a true fog system.

The pump and misting nozzle inside a misting system requires a water pressure rating of 30 to 60 psi to generate adequate levels of mist. A fog system operates under a much higher-pressure rating. To generate particles smaller than 50 microns in size, a fog system uses between 800 to 1,200 psi. When to Use Fog Humidifier in a Greenhouse
