Nutrient Delivery

Exact nutrients. Maximum yields.

Control EC, pH, irrigation timing, and feed strategy from one system — so every room gets the right recipe at the right time.

Why it matters

Fertigation is where yield gets won — or wasted.

Too much. Too little. Too late. Too inconsistent. Small mistakes in nutrient delivery compound quickly across rooms, cultivars, and harvests.

Growlink helps teams deliver the right recipe, verify what happened, and improve the next feed.

Growlink OS

Build the recipe in Growlink OS.

Define EC, pH, shot timing, dryback targets, irrigation schedules, and zone strategy before a single feed event runs.

Growlink OS fertigation strategy and recipe builder interface

Set targets

Define EC, pH, dryback, timing, and irrigation goals for each room, zone, and cultivar.

Schedule events

Run feed events by room, zone, cultivar, or growth stage — automatically, on the conditions your recipe defines.

Monitor performance

Track EC, pH, volume, runoff, and system status in real time with a complete event log.

Refine the next run

Use feed history to improve future recipes — every cycle builds on what the last one measured.

Connected workflow

From recipe to runoff, one connected system.

Growlink connects the plan, the dosing hardware, the irrigation event, and the crop response into one workflow.

Recipe Set the target.
Dosing Mix with precision.
Irrigation event Deliver to the room.
Runoff Verify the result.
Adjustment Improve the next feed.

Plan

Set EC, pH, shot timing, dryback targets, and irrigation goals — tied to each room and cultivar in your Blueprint.

Deliver

Execute irrigation and dosing across rooms and zones — every event logged, every batch verified against target.

Measure

Track what the crop received, returned, and responded to — so adjustments are based on data, not assumptions.

NDS and NDK

Choose the nutrient system that fits your operation.

Whether you need a fully custom system engineered to your specs or a lower-cost kit you assemble yourself, Growlink gives you a deployment path that fits your operation and budget.

Fully custom

Complete Nutrient Delivery

NDS — Nutrient Delivery System

A completely custom nutrient delivery system built to your facility’s specifications. Supports any flow rate, any number of injectors, and ships with the CORE Controller for unlimited expansion capability.

Best forLarge-scale and multi-zone operations that need a custom-engineered system designed, built, and commissioned by Growlink.

Self-Assembled Fertigation

NDK — Nutrient Delivery Kit

A self-assembled nutrient delivery kit with up to 8 injectors and the Connect Controller — a lower-cost path to precise, Blueprint-driven fertigation you build and install yourself.

Best forCost-conscious operations and hands-on teams who want Growlink precision and are comfortable assembling their own fertigation setup.

Execution accuracy

Deliver the recipe without the guesswork.

Growlink coordinates recipes, sensors, dosing hardware, and irrigation events so feed delivery stays aligned with the plan.

Recipe-connected fertigation

Link feed events to the strategy defined in Growlink OS — EC, pH, volume, and timing tied to the crop cycle.

Zone-level delivery

Apply the right feed schedule to each room, zone, or cultivar — different recipes running in parallel without bottlenecks.

Shot and dryback control

Coordinate irrigation timing, volume, and dryback targets — precise shot-by-shot execution across the entire fertigation schedule.

Exception visibility

Know when feed events drift from the plan — alerts and event logs surface deviations before they compound across harvests.

Agentic Cultivation™

Know what changed before the next feed.

Nova helps teams review fertigation performance, spot drift, and identify what to adjust before the next run.

1

Review fertigation performance

Compare EC, pH, runoff, irrigation timing, and crop response across rooms and cycles.

2

Spot drift before it compounds

Identify when feed events move away from the intended recipe — a dryback trending high, an EC running rich, a zone falling behind schedule.

3

Improve the next strategy

Turn performance data into better feed plans for future runs — accepted changes feed back into the Blueprint.

Nova surfaces data-backed recommendations. Your team approves changes, Growlink executes — every decision logged.

Professional services

Installed right. Performing from day one.

Growlink supports commercial teams through system design, installation, commissioning, and launch so nutrient delivery performs from the start.

Installation coordination

Hardware and system setup with your team or contractors — sensors calibrated and every feed verified before go-live.

Recipe launch support

Configure feed schedules, zones, and operating parameters so your fertigation strategy is running correctly from the first cycle.

Operator training

Help growers and operators understand the system from day one — recipes, dashboards, alerts, and day-to-day workflows.

Results

What operators achieve when every feed is controlled.

When nutrient delivery becomes consistent, teams can reduce variability, improve crop response, and make every feed easier to understand.

We went from shooting for 60,000 grams of fresh frozen a table to averaging 80–90,000 grams — and we use less water and fewer nutrients, because Growlink lets us dial everything in.
