Cooling & Humidification for Growing & Propagation

Humidification systems maintain proper vapor pressure deficit for crops to create the perfect growing environment in your greenhouse.

Fog cooling systems enhance greenhouse environments for any sort of cultivation, using  evaporative coolers creates an efficient growing area.


• Bedding plants – 30% more production.
• Cut flowers – Larger flowers and brighter colors,
• Propagation areas – 50%-200% more production.
• Tissue culture – Test-tube environment.

Water Pre-Treatment

Water Pre-Treatment

Basic water treatment, namely, a water softener is required for mineral removal. Based on dust-free requirements for the space additional components including reverse osmosis with automated membrane flushing and pre-treatment filtration can be added. 

MeeFog Pump

MeeFog Pump

The high-pressure pump maintains 1000 psi water pressure in order to atomize the water into tiny droplets that can evaporate overhead. The pump rack has a VFD with panel-mounted controller that maintains pressure when zone valves open and close.

Zone Valve Panel

Zone Valve Panel

The MeeFog Zone Valve Panel provides control for up to five fogging zones. It can use an on-board humidity sensor or signal from other controllers to actuate ball valves that are slow acting to eliminate water hammer.

Swirl Jet Nozzles

Swirl Jet Nozzles

The MeeFog Swirl Jet nozzles are stainless steel with a .006” orifice and output 7 lbs. per hour of fog. Fog nozzles mounted on stainless steel tubing can be spaced one per 200 square feet or denser for areas with open bay doors or in need of higher humidity.

System Overview

Nozzle Comparison

At an operating pressure of 2000 psi, the resulting average droplet size is roughly one tenth the diameter of a single strand of human hair.

MeeFog System Benefits

  • Bedding plants – 30% more production.
  • Cut flowers – Larger flowers and brighter colors.
  • Propagation areas – 50%-200% more production.
  • Tissue culture – Test-tube environment.
  • Low energy consumption.
  • Easy to service and maintain.
  • Ultra-fine fog droplets.
  • Stainless steel construction.
  • Flexible and easy to retrofit.

Droplet Comparison

Small droplets have a larger surface to volume ratio compared to larger droplets. This allows them to evaporate much more rapidly than larger droplets.

Featured Case Study

Takao Nursery
MeeFog System Creates the Perfect Growing Environment

The Challenge:
Summer temperatures in Fresno are often over 100°F. Takao Nursery needed to control humidity and temperature in order to have a successful greenhouse propagation business.

The Solution:
Takao installed a MeeFog system to provide uniform cooling and humidification over their propagation beds. They are able to meet customer demand by supplying consistently high quality plants with faster turnover rates.
