Growlink Terralink Substrate Sensor Growers Edge and the plunger sealReading the Root Zone with the Growlink TerraLINK Substrate Sensor The Growlink TerraLINK Substrate Sensor reads volumetric water content, bulk EC, and root zone temperature directly inside coco or rockwool. The probe runs as a TDR substrate probe Time Domain Reflectometry so EC drift doesn't corrupt the VWC number during aggressive drybacks. VWC reads 0. 01. 0 m m at 0. 02 from 053% and 0. 04 above. Bulk EC spans 020,000 S cm at (5% + 10 S cm) up to
