Rain-aware watering: delays with clear limits
GrowerHub can wait for forecast rain on an outdoor bed. The plan explains precipitation, delays and their deadline, while a covered greenhouse keeps its own watering rule.
Automated watering and grow controllers
Practical guides to irrigation, sensors, relays, lighting, and safe automation for homes, grow boxes, and greenhouses.

Demo valve: watering and a meter without equipment
Add a virtual valve to the shared demo farm, assign it to a greenhouse and explore watering, pulses and simulated litres in the same app screens.
Sensor-based watering: anchors for your own soil
Use readings after normal watering and before the next one instead of a universal percentage. GrowerHub checks trends and response to water.
Scheduled watering: days, time and duration
The new schedule does not require a soil sensor. Observe its plan first, then explicitly enable irrigation control when ready.
The next watering: a plan with clear reasons
The drying forecast uses local anchors, moisture history and the last watering. It gives a provisional time or explains which data is missing.
Automatic watering for plants: how to choose a system for pots, boxes or greenhouses
Practical analysis of the choice of automatic watering: when a simple timer is enough, when a humidity sensor is needed, how to evaluate the pump, reservoir, tubes and overflow protection.

Where to start
Start by defining what automation should change: a repeatable schedule, soil-moisture feedback, or controlled water delivery. Add feedback and safeguards one layer at a time instead of automating the whole system at once.
Compare a timer, sensor-based watering, and a controller by zone size and the cost of a wrong decision.
Calibrate the sensor in the actual substrate and confirm that its value represents the root zone.
Limit each run, recovery time, and daily delivery; provide leak detection and a manual lockout.
Choose your first step
| Situation | Where to start | Why |
|---|---|---|
| You only need a repeatable time-based routine | Schedule plus manual verification | It is easy to measure delivery without relying on an uncalibrated soil sensor. |
| The substrate dries unevenly | A sensor plus a log of manual watering cycles | A useful threshold comes from your own trend, not a universal percentage. |
| Water may run unattended | Runtime limits, leak detection, and safe shutdown | No software reading replaces an independent way to stop water. |
Build your first GrowerHub watering zone
Begin with monitoring and manual control, review the history, and enable automation only after the equipment and limits have been tested.
