Hypothesis

Testing: Verify live VPD/readbacks before escalating from low-wet dawn posture to band-coupled daytime assist. Expected outcome: Keep dew-risk and VPD-low stress at 0h through 07:00; after live VPD crosses high edge, hold controller-attributable VPD-high stress at or below 1.0h through handoff without exceeding 200 gal mist budget.

Hypothesis

Testing: Readback-gated escalation: compare live VPD edge crossing and confirmed climate-intent/readbacks with next-day controller-attributable VPD-high stress. Expected outcome: Across 72h, keep dew-risk and VPD-low stress at 0h; reduce controller-attributable VPD-high stress versus the recent 0.22-1.07h/day range while capping mister water at 300 gal/day and verifying readbacks before escalation.

Daily Summary So Far — this cycle will be validated at the next planning cycle.

Hypothesis

Testing: Readback-gated live-edge bridge: compare VPD edge crossing, materialized readbacks, and controller-attributable VPD-high stress; do not infer efficacy from forecast. Expected outcome: Keep dawn VPD-low and dew-risk stress at 0h; reduce controller-attributable VPD-high stress below yesterday’s 0.32h while dew margin stays >=8F and mister water remains ⇐300 gal/day.

Conditions

Outdoor peak

75.0°F

RH minimum

28.0%

Solar peak

670.0 W/m²

Cloud average

40.0%

Cool humid dawn, then dry afternoon ramp; forecast cloud field is inconsistent, so live VPD/readbacks govern. Prior plan anchor 7 vs self-score 5: safety held, but forecast/readback mismatch weakened efficacy.

Expected stress windows

vpd_lowhigh · 2026-09-21T06:48:00-06:00 to 2026-09-21T10:30:00-06:00

Hold wet duty; retain heat and drying exchange while dew margin stays safe.

vpd_highhigh · 2026-09-21T12:00:00-06:00 to 2026-09-21T19:00:00-06:00

Use live-edge band-coupled assist, fog excess 0.15 in the safe window, taper on observed recovery.

Parameter rationale

mister_engage_kpa1.6 → 1.25; VPD rises from 0.62 now toward 2.11 kPa by 16:00.

Make assist available near the active high edge without wetting the cool dawn.

fog_escalation_kpa0.4 → 0.15; Afternoon RH reaches 28% with forecast VPD above 2 kPa.

Bring heavy assist earlier during safe hot-dry venting while preserving dew margin.

mister_pulse_gap_s45.0 → 20.0; Dry ramp is concentrated from noon through early evening.

Improve recovery with shorter evaporation gaps, then taper after live VPD clears high edge.

Interior Light Evidence

  • Crop DLI: unavailable
  • Reason: source_day_incomplete
  • Provenance: legacy_invalid_exterior_proxy_plus_fixture_estimate
  • Validity: dli-validity-v1; 2024-01-01T00:00:00+00:00 → open
  • Qualified-light minutes and photoperiod remain independent of unavailable DLI.

Stress Hours

  • Heat stress (>85°F): 0.0h
  • VPD stress (>2.0 kPa): 0.9h
