Fertigation Release

This release contains fertigation cards for managing pH and nutrient levels for multiple feed tanks.

Water Sensors Device

The water sensors card manages an Agrowtek SXH series water sensor package.

Nutrient Sensors

Sensor readings are displayed on the front of the card.

Paristaltic Pumps Device

The nutrient pumps card manages an Agrowtek ADi series paristaltic nutrient dosing pumps.

Nutrient Pumps

This card lets you define the number of pumps the ADi device supports, and lets you name each pump with the name of the nutrient supplied by it.

The front of the card shows those nutrients and lets you manually turn the pumps on / off.

Nutrient Panel Device

The nutrient panel card manages an entire nutrient panel, consisting of valves to/from different tanks, valves for water in and out, sensors, pumps, and tasks for managing the nutrient levels in each tank.

Nutrient Panel

The Run icon (the running person) performs the following tasks

  • Fill Tank - Bring fresh water in from the water source to one of the managed tanks
  • Drain Tank - Drain water from one of the managed tanks to the facility drain
  • Measure Nutrient Levels - Circulate fluids from a tank through the sensors, recording data for that tank
  • Balance pH Levels - Apply acid and/or base fluids to a tank to bring pH readings within a hi/low range.
  • Add Nutrients - Apply different parts of each nutrient to raise tank EC to a specified level
  • Transfer Fluid - Transfer liquid from one managed tank to another managed tank
  • Flush Lines - Send fresh water through one of the input or output lines for a specified time

The front of the card displays the status of the valves, pumps, and sensors in the nutrient panel.

Fertigation Program

Last but not least, the Fertigation program card schedules these tasks (listed above) with specified parameters throughout the day.

It provides the automation component for hands-free water tank management.

Fertigation Card

The back of the card lets you configure the nutrient panel and different recipes for different plant cycles.

The front of the card displays the current or upcoming task, and a few recent tasks.
