REAL-TIME ROOT ZONE MONITORING: Measures volumetric water content (VWC), electrical conductivity (EC), and temperature for clear insight into soil and substrate conditions. RELIABLE UNDER STRESS: Designed to deliver consistent data even in high-EC environments and during extreme dryback cycles—perfect for demanding grow conditions. OPTIMIZE IRRIGATION DECISIONS: Use real-time root zone data to reduce water waste, prevent over-irrigation, and improve yield consistency. *Requires canopyLINK (sold separately) EASY INSTALL: Designed to perform in high-humidity and high-heat spaces like greenhouses, tunnels, and indoor farms. MADE IN THE USA: Fully integrated with Growlink OS and Copilot to support automated irrigation strategies and plant-stage-specific water delivery. Scale smarter—Growlink.

Real-Time Root Zone Intelligence

Growlink’s Terralink substrate sensor gives you the data you need to manage irrigation with precision. By measuring volumetric water content, electrical conductivity, and temperature at the root zone, it enables better-informed decisions for watering, nutrient delivery, and stress management.

Even in high EC or extreme dryback conditions, terraLINK+ stays reliable—making it the ideal tool for greenhouse growers pushing for consistency, yield, and water savings. It works seamlessly with Growlink Copilot, giving you a clear path to plant-stage crop steering.
