Forecast deviation14:37FORECAST_DEVIATIONackedAcknowledged: Observed solar is substantially below forecast, consistent with a cloud/weather shift and forecast error rather than equipment failure. Live climate is 82.9F, VPD 1.17 kPa, dew margin 11.0F; dispatcher action proof reports band satisfied and all equipment is appropriately idle. No tunable change is justified. Resolved 14:38 MDT.
Peak Stress14:57TRANSITIONackedAcknowledged: Peak conditions are within the active plan's expected envelope: temp 83.9F remains below dispatcher high 85.27F, VPD 1.22 kPa is only marginally above high 1.184, dew margin is healthy at 11.2F, and today's heat/VPD stress (1.44h/0.31h) is below plan expectations. Equipment is correctly idle; no tunable change warranted. Resolved 14:57 MDT.
Forecast deviation16:07FORECAST_DEVIATIONackedAcknowledged: No live miss: observed VPD 0.81 kPa at trigger and 0.95 kPa now versus 2.5 kPa forecast; positive historical VPD forecast bias (+0.94 kPa) overshoots reality. Current 79.4F/0.95 kPa is inside served bands, dew margin 9.7F, controller IDLE with all relays off. Forecast error/weather shift, not equipment fault; no tunable change. Resolved 16:08 MDT.
Forecast deviation16:22FORECAST_DEVIATIONackedAcknowledged: Observed outdoor RH is much higher than forecast, but greenhouse climate is stable and inside the served corridor: 78.4F, VPD 0.88 kPa, dew margin 9.1F, IDLE. All climate equipment is off as expected; no live controller miss or safety issue warrants tuning. Leave the active plan unchanged and monitor the humid overnight forecast. Resolved 16:23 MDT.
Decline18:09TRANSITIONackedAcknowledged: Decline is tracking safely: indoor 75.7F, VPD 0.74 kPa below the 0.99 high edge, dew margin 8.3F, controller IDLE, and all climate equipment off. Current tunables are already at conservative/default evening posture; no additional unwind write is needed before the forecast humidity rebound. Resolved 18:09 MDT.

Previous hypothesis: Measured pre-dawn VPD is 0.66 kPa with a healthy 10.2F dew margin, while the calibrated forecast calls for a clear dry ramp to about 85F, 3.0 kPa VPD, and 740 W/m2 by mid-afternoon. After yesterday’s 7/10 evaluation versus anchor 8, use live-VPD gating rather than forecast-only wetting: conservative overnight posture, then earlier band-coupled wet assist with pre-cooling as live VPD rises. Expect no overnight VPD-low stress, reduced controller-attributable VPD-high duration during the clear ramp, and dew margin at or above 8F; residual peak heat may remain capacity-limited. Result: Window scorecard: planner 77.2, temp compliance 73.8%, VPD compliance 79.8%, 1.21h stress, 0h dew risk, 0.14h cold stress; forecast overestimated heat/dryness (actual peak outdoor 79.7F vs 85F prior prediction, indoor RH proxy 49% vs 26% forecast). The intended live-gated moisture posture was only partially tested: 89 transition applications were missed and requested values returned to defaults. VPD stress stayed below the <2h goal, but exact tactical causality is unproven. Score: 6/10

New finding: When a sunrise plan has many missed transition applications, credit the outcome only to the observed controller posture and live conditions, not to the requested tactical values; retain live-VPD gating and verify applications before attributing moisture improvements. → Added to Lessons Learned

Hypothesis

Testing: Live-VPD gating versus cloud-biased forecast staging: reduce dry-ramp VPD stress without dew-risk or target hugging. Expected outcome: Keep dew-risk at 0h, reduce VPD-high stress below yesterday’s 0.77h and heat stress below 3.01h; residual heat may remain capacity-limited.

Cool dawn; cloud field conflicts with the dry solar/VPD ramp, so gate wetting on live VPD.

Expected stress windows

vpd_highhigh · 2026-09-16T11:00:00-06:00 to 2026-09-16T16:30:00-06:00

Live-edge wet assist; all-zone near high edge, fog excess 0.15, dew floor 8F.

heatmedium · 2026-09-16T13:30:00-06:00 to 2026-09-16T16:30:00-06:00

Pre-cool and ventilate; accept capacity-limited residual heat.

Parameter rationale

mister_engage_kpa1.6 → 1.34; Corrected VPD rises from 1.45 at 11:00 to about 3.0 at 15:00.

Earlier live-gated assist should reduce controller-attributable VPD-high time.

mister_all_kpa1.9 → 1.54; Dry solar ramp peaks near 688 W/m2 and VPD 2.69-2.99.

Serve east and center outliers without target-hugging or unsafe flooding.

fog_escalation_kpa0.4 → 0.15; Peak dry stress overlaps the 07:00-17:00 fog window; dew margin is 10.3F.

Make heavy wet assist available earlier while retaining firmware dew/RH gates.

New finding: Cool overcast overnight with live VPD near 0.8 kPa and healthy dew margin can safely use a conservative no-proactive-wet posture; when transition writes are missed, do not attribute the clean outcome to the exact tactical values. → Added to Lessons Learned

Hypothesis

Testing: Test conservative overnight wetting with stable dwell against VPD-low risk after a high-solar day. Expected outcome: Keep dew-risk at 0h and VPD-low stress below 0.5h while reducing heater/vent churn; accept no proactive wetting unless live VPD exceeds its high edge.

Cool overcast overnight; corrected VPD 0.40-0.89 and live VPD 0.73, so VPD-low and heat-retention risk outweigh dry assist. Prior plan scored 5 vs anchor 6 after 89 missed transitions.

Expected stress windows

vpd_lowmedium · 2026-09-17T01:00:00-06:00 to 2026-09-17T05:00:00-06:00

Suppress proactive wetting; use stable dwell and vent only for controller-attributable humidity.

Parameter rationale

mister_pulse_gap_s45.0 → 60.0; Forecast VPD 0.40-0.57 kPa overnight with 100% cloud.

Avoid repeating the prior 0.59-kPa too-wet event while preserving live-edge recovery.

temp_hysteresis1.0 → 1.5; Forecast drops to 61F before dawn; all climate relays are currently off.

Reduce heater/vent chatter and preserve heat without raising crop bands.

fog_escalation_kpa0.4 → 0.45; No solar, RH 60-78%, and no dry-ramp signal in the next 12h.

Hold heavy wet assist back overnight while dew margin remains above 8F.
