Hydroponic system design

Gully, bucket, DWC, pot, reservoir, dosing, sensors, and ESP32 control as one build.

This page shows the kind of grow-system design ElectronicsTech can build around: practical hydroponic gullies, bucket systems, Deep Water Culture, pot-based grow areas, nutrient control, pump timing, sensor placement, and clear reporting into local dashboards.

Hydroponic gully channels growing leafy greens — Gully grow channels need water movement, nutrient stability, simple service access, and reliable monitoring.

System flow

From reservoir to plants and back to data.

Reservoir

Nutrient tank with level, temperature, EC/CF, and pH measurement points.

Pump

Feed and circulation control with timed runs, manual override, and safety logic.

Gullies and Pots

Grow channels, DWC buckets, pot zones, return flow, and access for cleaning or plant changes.

Dosing

CF and pH dosing pumps with counters, calibration, and controlled correction cycles.

ESP32

Local firmware, display UI, MQTT/Home Assistant reporting, alarms, and history.

Controller details

ESP32 firmware matched to the real plumbing.

The controller side should follow the physical system, not fight it. Pump timing, dosing limits, calibration screens, daily counters, and alarms should match where the reservoir, gullies, buckets, drain return, and sensors actually sit.

EC/CF and pH calibration workflow
Temperature compensation and reservoir monitoring
Dosing counters and pump run limits
Manual override for filling, draining, and testing pumps
MQTT/Home Assistant entities for status and alarms

Hydroponic controller prototype wired for testing — ESP32 control work should be serviceable, testable, and easy to understand later.

Build checklist

What gets planned before wiring starts.

Plumbing

Reservoir size, gully fall, DWC bucket layout, return path, pump access, cleaning access, overflow risk, and pipe routing.

Electronics

ESP32 board choice, relay or MOSFET outputs, pump isolation, sensor inputs, display wiring, and enclosure space.

Software

Calibration, saved settings, sensor filtering, local fail states, MQTT messages, Home Assistant entities, and diagnostics.

Start a grow-system build

Send the grow layout and controller goal.

Include reservoir size, number of gullies, DWC buckets, or pots, pump type, sensors, dosing pumps, and whether Home Assistant reporting or SMS alerts are needed.
