The three numbers a substrate sensor streams — what each means, what raises or lowers it, and how each steers.

An in-substrate sensor (the AROYA/TEROS class of probe) streams three values continuously to the cloud: volumetric water content (VWC), pore-water EC, and substrate temperature. Master these three and the room becomes legible — you stop guessing and start reading. Each one moves the plant in a known direction.
