Mini Fertigator



The HI5000 Mini Fertigator precisely monitors and controls fertilizer concentrations and pH for small to mid-sized specialized hydroponics and greenhouse applications. The HI5000 is designed to be used with a mixing tank whereby fertilizer recipes can be mixed exactly to the needs of your crop. The system can be equipped to perfectly control the amount of fertilized water distributed to your plants, lowering costs and saving resources.

  • Customize your fertilizer mixtures with up to 4 stock tanks can be utilized for multiple crops and customized blending.
  • Perfect for Hydroponics & Indoor Gardening.
  • Precision nutrient & acid control to professional grower and advanced home grower alike.


HI5000 setup

Customize your fertilizer mixtures

The HI5000 comes equipped with 2 independent nutrient injectors, each with a max capacity up to 200 l/h. Additional injectors can be added to accommodate multiple nutrients.

Control pH accurately.

The HI5000 comes with a separate pH controller and designated pump specifically designed to handle the most aggressive acids.

Customizable and expandable.

Select the controllers, number of pumps and types of probes you wish to use. The system can be designed to your needs and specifications.

The Hanna HI5000 continuously measures the actual EC and pH of the blending tank or trough system and precisely adjusts the concentration of fertilizer and acid or base.

The HI5000 can be equipped with the HI8000 Series Controller allowing you to automate your entire irrigation system. Control pumps, solenoids, for a completely hands free operation.

The HI5000 (when equipped with the HI8000 Controller) has the capability to utilize the AgriCare software which allows you the ability to monitor and control the system remotely.
