Growlink Batch TankLINK – 30' Sensor Cables

Growlink batch tankLINK Controller for Real-Time Tank and Nutrient Management The Growlink batch tankLINK Controller handles pH, EC, temperature, and tank-level monitoring through a single 24VDC unit pulling roughly 5W at full duty. High-accuracy probes feed live readings back to Growlink OS, where recipes drive automated fill cycles and trigger deviation alerts before a batch drifts off-target. Operating range covers 50–122°F (10–50°C) and 0–75% RH non-condensing, which keeps it stable in greenhouse ranges and indoor flower rooms alike. Made in the USA with a 3-year controller warranty and 1-year sensor coverage, the LINK is built for commercial duty cycles. Recirculating and Batch-Fill Workflows in an Automated Nutrient Dosing System Two cable lengths cover most fertigation layouts. The 10-foot kit (GL-LINK-BATCH) suits compact mixing stations sitting beside the rack, while the 30-foot kit (GL-LINK-BATCH30) handles centralized rooms feeding multiple zones. Both kits ship the same probe set; only the sensor cable run differs. Place the unit close to the reservoir so the sensor cables drop into the active flow path. Probes pinned to a dead corner lag the real batch reading by several minutes, which matters during auto-correction. Standalone WiFi mode covers single-tank operations. Pairing with the Growlink HUB rolls the device into a wider automated nutrient dosing system. Shared logging, alerts, and recipe libraries cover every fertigation tank in the operation. Key Features Automated Fill Control: Triggers refill cycles when the level sensor drops below threshold, so a recirculating tank doesn't run dry mid-irrigation. Real-Time pH, EC, and Temperature Probes: High-accuracy sensors stream live data so the controller corrects nutrient drift before it shows up at the canopy. Growlink OS Recipe Automation: Set targets per crop stage and let the system mix, dose, and log every fill cycle without manual intervention. Standalone or HUB-Connected Operation: Run as a self-contained WiFi nutrient tank monitor or as a node inside a multi-tank Growlink HUB deployment. Made in the USA, 3-Year Controller Warranty: Commercial-grade build with 1-year sensor coverage on probes for greenhouse and indoor cultivation.
