CEA recovered solution — separate sanitation, treatment and reuse boundaries

A recovered solution can match EC and still be unsuitable for roots. Separate collection, isolation, treatment, residual checks and reuse authorization.

CEA sensing and image estimation — sensor placement and projected leaf area

Combine CO₂, EC, pH, DO, flow, level and pressure to separate spatial differences, instrument bias and sample transport delay. Check circulation, ventilation and water-balance residuals.
