Verdant Free explains the environment and builds plant memory. Verdant Pro uses Edge to verify controller outcomes and forecast drift.
Independent grow intelligence using the records and sensors you already have
A sensor and a local box that watch the tent continuously, so Verdant can verify outcomes instead of inferring them
Pro needs a Drift Detector in the grow space. Edge on its own does not enable it — the sensor is what gives Edge something worth resolving. Hardware availability and pricing are shared here on homegrown.guide, not through the App Store.
Verdant Pro
Verdant Free reasons about whatever your controller happens to report. Pro adds a sensor that watches continuously and a local box that does the thinking — which is the difference between explaining a bad day afterwards and seeing it coming.
The sensor
A small probe you put in the tent at canopy height. It reads temperature, humidity, pressure, and air quality every few seconds — fast enough to catch the short excursions a ten-minute poll flattens into nothing.
The local box
Edge stores the full-resolution history and runs the forecasting continuously, whether or not your phone is open. It is a box on your network — not an account, not a cloud service, and it keeps working when the internet does not.
Edge projects each measurement forward and tells you when it will leave the safe range for your stage — with a time, so there is something to act on.
A seven-day scorecard for your controller: did the equipment that switched on actually fix the problem, and how long did recovery take?
Drift, recurrence, overshoot, and oscillation are visible because the readings behind them were never averaged away.
