In brief
Independent fluid channels, channel identity, mixing logic and the separation between dosing a stock solution and producing a plant sensory outcome.
Explanation
Four pumps allow four liquids to be added independently. The channels control liquid volumes. They do not directly control sweetness, acidity or aroma.
Architecture
The documented motor-control architecture uses STEP/DIR microstepping drivers of the A4988 class. Driver selection defines command generation and protection requirements; it does not determine pump volumetric accuracy.
Stock 1–4→Calibrated channel→Injection point→Mixing delay→Reservoir measurement
Safe channel definition
| Channel | Permitted role | Required metadata |
|---|---|---|
| 1 | water or defined stock | fluid ID, batch and density |
| 2 | nutrient stock A | full chemical composition and compatibility class |
| 3 | nutrient stock B | full chemical composition and compatibility class |
| 4 | correction or experimental stock | purpose, maximum dose and exclusion rules |
