Growlink NutriLINK Drives Eight Dosing Pumps With pH and EC Feedback
The NutriLINK runs a feed line with eight universal outputs for dosing pumps and dedicated inputs for pH, EC, and flow sensors. The controller writes recipes to mL/gal precision and adjusts on the fly when the sensor stack drifts off target. Output channels handle peristaltic pumps for base feeds, supplements, and acid in the same dose cycle. Smaller rooms run the full feed stack on a single controller without a larger NDS rack.
Fertigation Controller Built for Modular and Scalable Grow Rooms
The nutrient delivery controller pairs with the broader Growlink LINKS line, so a single room can scale into a multi-zone fertigation system. Adding valveLINK or quadLINK modules extends control over more drip zones. Dosing recipes live in the cloud, and every adjustment to a target EC or pH lands on the controller within seconds. Real-time feed data flows back to Growlink OS for trend graphs and alert thresholds. The result is a fertigation controller that fits a single bench today and a multi-room facility next year.
Key Features
- 8 Universal Pump Outputs: Drive eight peristaltic dosing pumps from one controller for base feeds, supplements, and acid in the same cycle.
- pH, EC, and Flow Sensor Inputs: Dedicated probe inputs close the loop on each dose cycle and surface drift before it reaches the canopy.
- mL/gal Recipe Precision: Write feed recipes with mL/gal accuracy and adjust targets remotely from the Growlink portal.
- Growlink LINKS Expansion: Pairs with valveLINK and quadLINK modules to grow from one zone to a multi-zone fertigation rack.
- Cloud Recipe Storage: Feed recipes and sensor logs live in the cloud, accessible from the Growlink mobile app and web dashboard.
