Consistent yield, stronger terps, repeatable rooms: leaf, air, light and root zone from day one." url: https://growsensor.co/shop/grow-sensor-pro-bundle --- GS-SYS · Complete system # The Grow Sensor PRO system The complete canopy system for facilities. Consistent yield, stronger terps, repeatable rooms: leaf, air, light and root zone measured together from day one. Choose SubSense or SOLYX 14 as the substrate probe. £699 £817 Pay in 3 interest-free instalments of £233 with shop Pay Substrate probe 1 - 60-day money-back guarantee - 2-year warranty - Ships to UK, EU, US, CA, AU, NZ One system ## Leaf to root zone, on the same timeline. The PRO reads the canopy while the substrate probe reads the media. Plant response and irrigation on one graph, in one app. [Image: Grower inspecting canopy plants in a commercial grow room with a Grow Sensor PRO hanging in the background] Measurements ## Fifteen channels. No estimates. Live from day one. Canopy channels from the PRO's dedicated sensors; root-zone channels from the substrate probe in the kit. 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 nosetrial Root zone - Water content - Substrate EC - Substrate temperature - Runoff pHtrial - Runoff ECtrial - Runoff volumetrial Via the substrate probe in the kit. 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. Grow Plus is optional. The Grow app · iOS & Android · Free Technical specification ## Accuracy, published.

Top-shelf results don't happen by accident. Every channel from every cycle is logged, so you can pull up your best run and hit the same targets again.

Plug a substrate probe into the PRO's underside RJ12 via the connector block: eight supported models, from SubSense to METER and Acclima. One connects at a time. Supported substrate probes - Grow SubSense - Delta-T WET-150 - Acclima TDR-310W - Acclima TDR-315N - METER Group TEROS 11 - METER Group TEROS 12 - METER Group SOLYX 14 - Growlink Terralink Integrations - Home Assistant, for automations off live readings - API access, for dashboards and custom logic - The Grow app (iOS & Android), free with unlimited history 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 [Image: Nichilas Ezzo] Nichilas Ezzo Head grower, FarmaceuticalRX > “I've never second guessed the readings.” FAQ ## Before you order. Yes. Every unit is tested end-to-end as an assembled device, not as loose components. Temperature and humidity are verified in a stable test chamber, with multi-point checks across temperature, humidity, PPFD and spectrum. Calibration and test certificates are available on request. The Grow app is free with the sensor, with unlimited history. Two optional subscriptions sit on top: Grow Plus (£9.99 a month after a free first month) adds a second sensor per room, recipes and a grow diary; GrowOps is the workspace for facility teams. Hang the sensor above the canopy, connect it to 2.4 GHz Wi-Fi through the app, and readings start. No installer, no wiring. If the internet drops, the sensor logs offline and syncs when the connection returns. Both read water content, EC and temperature into the same app. Most rooms take SubSense, the default in the complete system. SOLYX 14 still does the same job, with the edge in extreme high-EC conditions. The SubSense probe, plus a fixed list of SDI-12 models: Delta-T WET-150, Acclima TDR-310W and TDR-315N, METER Group TEROS 11, TEROS 12 and SOLYX 14, and Growlink Terralink. Every probe connects through the waterproof RJ12 connector block. One probe at a time. 60-day money-back guarantee: if you're not satisfied, email us within 60 days for a full refund. Every unit also carries a 2-year warranty against defects in materials and workmanship. GS-SYS · Complete system ## The Grow Sensor PRO system 60-day money-back guarantee. 2-year warranty.
