Mist sprinkler, used in misting systems is a type of micro sprinkler used to cool temperatures in greenhouses. It supplies moisture from all directions in form of cool mist which results in a temperature drop inside the greenhouse environment.
Specifications of Misting Device
- 4 arms or outlets each with a nozzle.
- Connection pipe of 50 cm length
- Flow radius of 0.8 – 1 M
- Discharge rate of 5.5 L/H
- Operates at a pressure of 3 to 4 bars.

Why Use a Misting Kit in Your Greenhouse?
A misting system offers much more than just watering your plants. Here’s why it can be an essential part of your greenhouse setup:
Temperature Control
Use of misting device benefits both irrigation and temperature reduction which is vital for plant health and growth in hot regions.
In hotter regions, temperatures in greenhouse environments exceed normal conditions and it becomes hard to control. The most effective way to lower such temperature conditions is by using mist or spray systems.
Increasing Humidity
A misting system helps maintain consistent humidity, which:
- Reduces plant stress
- Encourages better growth
- Prevents issues like leaf curling or browning
Moisture Distribution
Misting systems are often used in propagation greenhouses to deliver short, regular bursts of moisture that keep young plants alive. Seedlings are watered using fine mist or sprays to prevent overwatering or damage of the stems or tiny roots.
Improved Plant Health and Yield
By mimicking natural rainforest conditions, misting helps:
- Keep leaf surfaces clean
- Deter some pests like spider mites that prefer dry environments
- Encourage flowering and fruit production
How does a Misting Systems Work?
Misters supplies water through its outlets which contain tiny nozzles that ooze out 5-micron water droplets in mist form. As water flows through the pipe to the mist head under high pressure, it is forced out through tiny nozzles as smaller water molecules or mist.
The mist covers a large area and has uniform distribution in the greenhouse environment.
Components of Misting System
- Booster Pump: high pressure pump is a basic requirement for generating high pressure flow to enhance mist formation. Various pumps are available and ideal for use in misting systems.
- Tubing: the performance of your misting system depends on the tubing used.
- Controllers: device that controls the misting system by incorporating sensors and timers to enhance automatic spraying.
- Misting nozzles: provide the fine mist spray.
- Inlet filter – 0.1 mm dual mesh filter that prevent debris from clogging the pipe or nozzles.
- Solenoid Valve – to control the flow of water in by opening or closing water supply.
- Water supply pipe – PVC or HDPE pipe to carry water from the source to the mister heads.
How to Choose Misting Systems
The pumps needed for a high-pressure misting system can differ in dimensions, style, and expense. Consulting with an expert supplier will assist in identifying the most suitable pump type for a specific application.
Along with the pump choices, there are various kinds of tubing for misting systems that can be utilized. Certain applications are more effectively designed using flexible tubing, whereas others require rigid tubing. The particular use and design of the misting system will often guide the selection of the most appropriate tubing type for a specific requirement.
The final factor to consider is the nozzles of the misting system. These come in various flow rates to enable customization of a misting system for any application. Whether the system is used in industries or greenhouses, the wide range of nozzle sizes provides an ideal match for any environment.
Choosing the Right Misting Kit
Before you invest in greenhouse misting systems consider the following questions.
What size is your greenhouse?
The greenhouse measurement will determine the pipe size, and how many mist heads and nozzles to use. It is also vital to determine the nozzle spacing and size applicable.
What are you growing?
Learn the optimal temperature and humidity requirements for your plant in different growing cycles.
- Tropical plants need higher humidity (70–90%)
- Vegetables typically prefer moderate humidity (50–70%)
- Succulents and cacti may not need misting at all
Your system should be tailored to match the specific crops or needs of the greenhouse.
Do you need automation?
Some kits come with timers, thermostats, or humidity sensors. This helps automate misting cycles, so you don’t to manually operate the system.
What is your water quality?
Hard water can clog misting nozzles. If your water is high in minerals, consider a filter or reverse osmosis system.
Types of Greenhouses Misting Systems
Low-Pressure Misting Kits
Operate on standard water pressure of 30 – 60 psi. Ideal for small to medium spaces, gothic arc greenhouses and indoor grow tents. The benefit is that they are cheap and easier to install. However, they produce larger water droplets and are less effective for cooling.
High-Pressure Misting Kits
These use pumps to boost water pressure up to 1000 psi, creating ultra-fine droplets that evaporate quickly and cool more efficiently. Offers professional grade cooling and minimal wetting. The downside of these systems is their high cost of investment.
Fogging Systems
Technically, a step up from misting, foggers produce an even finer aerosol mist. They’re typically used in large-scale or sensitive environments like orchid houses.
How to install Misting Systems
- Installation of misting systems requires proper irrigation technician to ensure correct component connection and performance.
- Planning and Design of the Layout: Map out where you’ll place misting lines and nozzles. Focus on even spacing and coverage.
- Attach the supply line: Connect the main pipe to the water source. Near the water source install a water filter and then a pressure regulator.
- If the water pressure is lower than the required, connect a booster pump to the system.
- Mount and install a controller onto the wall inside the greenhouse or nearby building with electricity access.
- Install and connect solenoid valves. Connect the wires to the controller.
- Drill the delivery PE pipe using a drill bit and connect mist tubing.
- Run the system and check for leaks. Adjust nozzle angles and pressure as needed
