One system
Leaf to root zone, on the same timeline.
The PRO reads the canopy while the SubSense probe reads the media. Plant response and irrigation on one graph, in one app.
Measurements
Fifteen channels. No estimates.
Live from day one. Canopy channels from the PRO's dedicated sensors; root-zone channels from the included SubSense probe.
Climate & environment
- Air temperature
- Relative humidity
- CO₂
- Dew point
- Atmospheric pressure
- Ambient VPD
Light & photosynthesis
- ePPFD (extended spectrum)
- ePAR
- eDLI
Plant response
- Leaf surface temperature (IR)
- True leaf VPD
- Leaf-to-ambient differential
- Plant VOCs — the nosesoon
Root zone
- Water content
- Substrate EC
- Substrate temperature
- Runoff pHsoon
- Runoff ECsoon
- Runoff volumesoon
Via the included SubSense probe.
The software half
Every channel, on one screen.
Readings land in the Grow app as split graphs: water content, pore water EC and the rest, with your limits drawn on them and an alert the moment a room leaves its band. Free, with unlimited history. No subscription.

The honest fit
Built for some rooms, not all.
For you if
- You grow indoors and are judged on yield, quality and repeatability
- You want canopy, climate and substrate data in one calibrated system, not scattered devices
- You run multiple rooms, zones or cycles and want consistent targets
- You steer on trends and alerts, not on feel
Not for you if
- You grow outdoors only
- You need a basic thermometer and hygrometer, nothing more
- You want the lowest-cost monitor on the market
- You don't plan to act on the data
