Mist irrigation is a perfect way to water crops, increase humidity and cool off greenhouse or outdoor temperature through very fine water droplets spray. Mist irrigation systems in Kenya are used in vegetable seedlings nurseries, greenhouse vegetables, and flowers.
Grekkon Limited is a large supplier of 2-way and 4-way nozzles mist irrigation systems to vegetable and flower growers in the country. They are easy to install and use, and are economical at a price of Kes 350 a unit. Our misters for irrigation work with a 200 mesh irrigation water filter. This will keep away dirt that will otherwise block the tiny nozzles

How does a mist irrigation system work?
The cold tiny water droplets from the mister create a huge surface area which increase humidity and lowers the temperature as they evaporate. Some droplets fall on the growing media or soil surface and are up-taken via the root system

How to set up misters for irrigation
Connect to the water source
The line will be connected to a high-pressure water pump that pumps water from the source to the misting system’s HDPE mainline. Add a 200 mesh water filter along this line to prevent clogging by sediments in the water
Connect the misters
Misting tubes will be connected to the misting system’s mainline at intervals of 1M. The shorter the misters, the higher the pressure and the finer the water droplets are.
Add nozzles and connect the 2-way or 4-way misting nozzles to the hanging tubes

Mist Irrigation FAQs
1. What is mist irrigation?
It is watering a plant by spraying water droplets on it. This irrigates the plant and cools it too.
2. How much water do misters use?
Grekkon Limited’s misters use close to 5 litres per nozzle, per hour or 600 - 800ml per minute
3. What is the difference between fogging and misting?
Misting produces water droplets of 200 microns in size. They fall to the ground quickly. A fogging system releases droplets that are 10 microns in size. They remain suspended in the air and evaporate
4. How far apart should misters be?
We set our misters at 1M apart. The lateral lines to the misters are 32mm/ 1 inch in diameter.
5. How do I fix my misting system?
- Remove the clogged nozzle from the system
- Remove the O-ring from the nozzle
- Dip the nozzle in white vinegar or CLR for an hour
- Rinse the nozzle, flush the misting line and mount the nozzle back to the system
6. How much pressure should be in a misting system?
From 2.4 bar or 24M head
7. Do you need a pump for a misting system
Yes
8. How long should misters run?
For as long as they are needed to
9. How high should you hang irrigation miters?
