Greenhouse Cooling: Protect Your Plants, Boost Growth, and Maximize Efficiency
Grow year-round in any climate and reduce plant stress
A greenhouse cooling fog system maximizes cooling efficiency in hot, dry climates, preventing plant stress during heat waves. In colder climates, a greenhouse humidifier maintains ideal humidity for nutrient uptake and plant health. Designed for precision, this fog system ensures optimal growing conditions year-round.
Optimize propagation
Plants take in carbon dioxide from the atmosphere through their pores. When their pores open, a chain reaction begins. Water is drawn up from the plant’s roots and travels throughout the plant. The water evaporates and goes back into the microclimate. This process is called plant transpiration. When plants transpire, it is like human perspiration. A stoma opens and allows water to escape. Stoma function is connected to the humidity level.
When growing plants don’t have enough humidity, they close their stomata. This means that CO2 intake levels get lower and the plant starts to “stress”. Plants grow slower and produce less food in such conditions like this. If the humidity level is too low, the plant’s protective mechanisms can’t make up for the stress caused by a lack of water in the atmosphere. If there isn’t enough humidity in the microclimate, the plant will eventually wilt and die. This is certainly what you do not want in your garden centers.
Control the propagation of young plants and seedlings by maintaining constant humidity levels with our commercial greenhouse humidifier system. The correct environment allows faster and more even rooting for maximum output.
Even distribution means even growth and production
Strategically placed nozzles provide greenhouse cooling and precise humidity control. Ultra-fine 6–10 micron droplets flash evaporate instantly, cooling the air or increasing humidity levels. Whether for temperature control and humidification, a greenhouse humidifier creates the perfect environment for healthy plant growth.
Anti-drip design
MicroCool’s advanced anti-drip nozzles prevent drips, ensuring a clean and efficient greenhouse cooling fog system. By eliminating excess water and drainage issues, this highly effective fog system protects crops from water damage.
Fast, easy installation
Custom stainless steel or flexible lines provide versatile greenhouse cooling or greenhouse humidifier design options and make installation a breeze. ROC collars allow for 360° nozzle rotations to direct fog exactly where needed.

Seamless Climate Control Integration
Stomata play a crucial role in plant health, regulating gas exchange and water loss. When temperatures rise too high, plants close their stomata to conserve moisture, leading to reduced nutrient uptake and stunted growth. A greenhouse fogger system helps maintain optimal temperatures, keeping stomata open for efficient carbon dioxide absorption. By integrating seamlessly with any climate control system, MicroCool’s fogging solutions use real-time data and automation to adjust cooling as needed, ensuring a stable environment that supports healthy, vigorous plant growth.
Greenhouse Cooling Systems Designed for Your Unique Growing Needs
We work closely with you to create the ideal greenhouse environment. Our greenhouse cooling system instantly reduces temperatures through flash evaporation while never exceeding humidity levels. To ensure even cooling, we incorporate zone control to address hot spots and carefully assess ventilation placement and airflow. By tailoring each system to your greenhouse’s unique layout and needs, MicroCool delivers precise, efficient cooling for optimal plant growth.
As a grower, you understand the importance of temperature and humidity control for optimal production. If your greenhouse’s temperature does not stay at the proper level despite regular ventilation and shading, you’ll need to add cooling so your plants can thrive. Air conditioning (mechanical refrigeration) is often utilized in homes and offices. However, in the agriculture industry, air conditioning is not cost-effective for greenhouses with a large quantity of heat to be reduced. Evaporative cooling, on the other hand, is a simple and inexpensive option for growers in this agriculture sector, as it can help them save money.
For evaporation to occur it needs heat. The surrounding air provides this heat energy, causing the air temperature to fall as water evaporates. At the same time, as the evaporated water converts into water vapor and is added to the surrounding air mass, the humidity of the air rises.The volume of cooling possible with evaporative systems is determined by the humidity of the atmosphere and the air’s original temperature. In a nutshell, the drier the initial air, the more water it can absorb, and hence the lower the final air temperature will be. Warmth also enables more water vapor to be held in comparison to cold weather.
MicroCool’s fog solution is a more dependable option for evaporative cooling systems, which most greenhouses rely on to keep their plants healthy. It gives you greater control of the atmosphere and how you grow your plants. Every indoor grower needs this kind of control when it comes to gardening.
Understanding the Fog System
In greenhouses with natural-ventilation systems, fog system technology is frequently used. These natural ventilation systems just utilize strategically placed vents that don’t require any mechanical fans. The additional airflow resistance produced by evaporative cooling pads makes it difficult for natural-ventilation systems to overcome.
The fog system equipment can be used to evenly distribute cooling throughout the greenhouse, in contrast with a pad-and-fan system. The fog system’s nozzles are placed throughout the greenhouse, resulting in a more uniform cooling pattern. In every 50–100 square feet of the growing area, there will be at least one nozzle.
The Water Properties of the Fog System
To generate very fine droplets that evaporate before they touch the plant surfaces, greenhouse fog systems use a great deal of water pressure (900 pounds per square inch and higher). The usage of water per nozzle is quite low, about 1-1.2 gallons every hour.
To prevent clogging of the small nozzle openings, the water must be free of any impurities. This is why water treatment (filtration and purification) and a high-pressure pump are recommended with all fog systems. Water pressure should not be an issue, as the usually tiny supply lines can handle it. This helps the agricultural sector with growing warm-weather vegetables.
Ultrasonic Properties
In comparison to mechanical ventilation systems equipped with compressed air humidifiers, fog systems create much less noise. This can be a significant advantage for employees and customers who spend long periods of time in commercial greenhouses.
Determining Cooling Efficiency
The optimal cooling that evaporative-cooling systems can provide is determined by the air’s initial temperature and humidity or moisture content. A regular thermometer and a relative humidity sensor are all you need to measure these things. You may use a psychrometric chart to compute the maximum possible relative humidity (100 percent) wet bulb temperature by taking these measurements.
A wet-bulb temperature is the temperature in the atmosphere when water is evaporating from it. When that happens, the air gets cooler. You can calculate how much cooler it will be by calculating the difference between the original temperature and the wet-bulb temperature. The actual temperature drop realized by an evaporative-cooling system is more than likely to be about 80% of the theoretical wet-bulb depression, given that few designed systems are 100% efficient.
