Mist Irrigation


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 temparature as they evaporate. Some droplets fall on the growing media or soil surface and are uptaken via the root system

How to set up misters for irrigation

  1. 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

  2. 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.

  3. Add nozzlesConnect the 2-way or 4-way misting nozzles to the hanging tubes

Mist Irrigation FAQs

We set our misters at 1M apart. The lateral lines to the misters are 32mm/ 1 inch in diameter.
