The Growlink nutriLINK (GL-LINK-NUTRI) is an 8-output precision fertigation controller designed for batch-tank nutrient delivery. It provides eight universal dosing-pump outputs plus integrated pH, EC, and flow sensing, allowing nutrient recipes to be automated and verified using real-time feed data. Connected through the Growlink HUB, it communicates with Growlink OS and Growlink Copilot, where feeding data is logged, trended, and used for data-driven crop-steering decisions.
• SKU: GL-LINK-NUTRI
• Brand: Growlink
• Product Line: LINKS
• Universal Pump Outputs: 8
• Integrated Sensor Inputs: pH, EC, Flow
• Primary Application: Batch-tank fertigation
• Pump Control: Each output controls a dosing pump
• Nutrient Applications: Base nutrients, micros, additives, Cal-Mag, bloom boosters, pH acid, pH base, and other recipe inputs
• Dosing Programs: Customizable, stage-specific recipes through Growlink OS
• Growth Stages: Propagation, early veg, late veg, transition, early flower, late flower, flush, and other custom stages
• pH Monitoring: Integrated real-time feed pH measurement
• EC Monitoring: Integrated real-time feed EC measurement
• Flow Monitoring: Confirms that dosing/feed delivery actually occurred and can identify deviations
• Growlink OS: Centralized programming, monitoring, data logging, and historical analysis
• Growlink Copilot: Yes — live dosing, pH, EC, and flow data can feed into Copilot's crop-steering recommendations
• Data Logging: Real-time and historical data through the Growlink OS cloud dashboard
• System Connection: Requires Growlink HUB
• LINKS Ecosystem: Works alongside valveLINK, canopyLINK, terraLINK sensors, hvacLINK, and other LINKS modules
• Control Architecture: Closed-loop fertigation rather than simple timer-based dosing
• Batch-Tank Design: Designed for dosing pumps that add nutrients into a batch tank
• Inline Direct Injection: Not designed for inline direct injection; Growlink's Core Controller with NDS 2.0 is the higher-tier solution for that application
• Expansion: Multiple LINKS modules can be combined through the Growlink HUB for larger cultivation systems
• Platform Compatibility: Growlink OS (HUB-connected)
Key Advantage: The nutriLINK combines 8 dosing-pump channels with integrated pH, EC, and flow feedback, turning batch-tank fertigation into a closed-loop, data-driven process. Instead of simply running pumps according to a timer, the system can verify delivery and provide live nutrient data to Growlink OS and Copilot for more consistent feeding and crop steering.
