Run irrigation and fertigation with one system.
From daily irrigation programs to complex multi-zone fertigation, Agrinodes gives your farm one system to plan, run, monitor, and record every operation — live and historically.
01 · Programs
Irrigation plans built around how your crop runs
A Program is a named irrigation plan you build once and run on a repeating cadence. Choose the timing style that matches how the crop wants to be watered, then compose the steps — valves, durations, pump behaviour, and any fertigation — into a sequence the system executes for you.
When conditions on the day call for something outside the normal Program, use a Quick Run for an immediate one-zone action, or a Custom Run for a one-off multi-step sequence. Both run through the same pump, valve, and safeguard coordination as a scheduled Program.
Pick the days of the week and the time. Best for established beds with predictable demand.
Tue · Thu · Sat · 06:00
Set a cadence — every 1, 2, 3 days from a start date. Best for newly planted blocks ramping up cycle by cycle.
Every 3 days · noon
Run on a tight cycle inside a daily window. Best for high-frequency hydroponic / bag growers.
Every 45 min · 06:00–18:00
// Program Composition
Plan once. Reuse across blocks. Edit without breaking history.
One named definition with the timing style. “Block A · Daily Drip” stays canonical.
Ordered phases inside one run — pre-flush, dose, post-flush. Each step has its own duration and (optional) recipe.
Which zones are part of each step. All zones in a step share the step's duration and run together.
02 · Fertigation
Build one integrated fertigation system.
If you already have an irrigation controller, a dosing setup, and a few sensors that do not quite work together, Agrinodes gives you one coordinated workflow. Recipes, stock tanks, and dosing devices sit directly inside Programs, so fertigation becomes part of the irrigation run instead of another separate system to manage.
Start with the dosing hardware you already own, then add the sensors that match your budget and the level of verification you want. When a fertigation step runs, the Gateway coordinates dosing alongside valves and pumps while flow, pressure, EC, and stock-level evidence can be recorded and reviewed afterward.

Recipes & batch traceability
Author a recipe once — name it, set the target EC delta and pH range, choose the stock solution. Attach it to any Program Step. Every batch you mix is recorded with concentration, volume, mixer name, and timestamp — so the audit trail proves what was applied, where, and when.

CONFIDENCE VERIFICATION
With the right sensors installed, Agrinodes can assign a confidence verdict to each fertigation run — using flow, EC, and pressure data to tell you whether nutrients actually reached the crop.
Bring the dosing device you already own
Keep the injector, Venturi, or batch tank that already fits your farm. Agrinodes becomes the layer that ties dosing, irrigation, and verification together, then lets you extend the system with the sensors that make sense for your crop and budget.
Water-powered proportional injector. System verifies via flow + EC.
Inline proportional dosing. Same control surface, same verification.
Pressure-differential aspirator. System watches pressure + EC to confirm uptake.
Pre-mix and pour. Optional level sensor tracks consumption per run.
Grower question
Did water flow?
Flow sensors on the line confirm water moved through the zone during the run.
Grower question
Did dosing happen?
Dosing activity is recorded against the step where the recipe was applied.
Grower question
Was pressure in range?
Pressure sensors can flag whether line pressure stayed within the expected band during irrigation.
Grower question
Is there enough stock left?
Tank level sensors can track stock volume so you know before the next run whether the tank needs refilling.
Build verification to match your budget
Start with the hardware you already trust, then add flow, pressure, EC, tank-level, or other supported sensors as you go. A simple setup can still coordinate fertigation; a richer sensor stack gives you stronger evidence about what actually happened during each run.
Integrated fertigation as an add-on
Fertigation is an optional paid feature at $69/month per enabled farm. Growers whose dosing hardware and installed telemetry support it can validate the integrated workflow during the trial, then decide whether to keep running it as an add-on afterward.
03 · Pump & Valve Control
Pump and valve coordination in one system.
Gateway and Node Mains each support one pump output and seven valve outputs. Programs choreograph the full water path — startup, sequencing, waits, and close-down — so the pump and valves behave as a coordinated system, not as separate manual steps.
Compatible pump types
The Gateway provides the relay signal — it does not replace mains-voltage wiring. Pump and mains-voltage valve wiring must be installed by a licensed electrician in accordance with local electrical regulations.
Pump startup
The pump channel comes on after at least one downstream valve is confirmed open. Startup delay is configurable per Program.
Valve sequencing
The system opens and closes valves in the order the Program defines. The pump follows the valve state — it does not run independently.
Waits between steps
Programs can include wait steps between zones to allow pressure to equalise or fertigation to complete before the next valve opens.
Safe close-down
At the end of a run, valves close before the pump drops. Programs and Quick Runs follow the same close-down sequence.
Practical protection
If flow does not appear after pump start, or all valves close during a run, the pump stops and an incident is opened. This is designed practical protection — not a guarantee against every failure mode.
04 · Quick Run & Custom Run
Ad-hoc irrigation, same safeguards.
Not every irrigation decision fits a scheduled Program. Quick Run gives you one-tap spot-watering for a single zone. Custom Run lets you build a multi-step sequence on the fly. Both run through the same pump, valve, and safeguard coordination as a scheduled Program.
One-tap spot-watering for a single zone. Set the zone and duration — the system handles pump startup, interlock checks, and safe close-down automatically.
Build a multi-step sequence on the fly. Chain zones, set durations, include fertigation steps and waits — all as a one-off run without creating a permanent Program.
SAME SAFEGUARDS AS PROGRAMS
Quick Runs and Custom Runs run through the same pump interlock, valve sequencing, and safeguard checks as scheduled Programs. A one-tap run is not a bypass — it is a scheduled run with a sequence of one.
05 · Offline Control
Keep operating — even without internet.
If farm internet or Wi-Fi drops out, the Gateway keeps running its existing Programs and supports on-site Bluetooth local control from the app. That means you can still operate valves, stop irrigation, pause Programs, run pumps, and check sensor readings without cloud connectivity.
