Daily Summary So Far — this cycle will be validated at the next planning cycle.
Hypothesis
Testing: Peak-only aggressive dry-day control: strong fog/mist during 11:30-17:00, then earlier relaxation than yesterday to reduce VPD-low stress and mister-water waste. Expected outcome: Keep peak indoor VPD below ~1.8 kPa, VPD-high stress under 1.5h, VPD-low stress under 1.0h, dp_risk_hours at 0, and mister water below yesterday’s 489 gal while cost remains below the 7d average.
Conditions (structured)
78.0°F
8.0%
881.0 W/m²
64.0%
very dry Sunday with strong solar until mid-afternoon; cold wet front Monday evening into Tuesday
Expected stress windows
engage/all 1.10-1.55, 20s gap, fog_escalation 0.20-0.22, 150-180s sealed cycles
relax thresholds/gaps after peak; bias_cool +3 overnight
cold/wet-front conservative misting, long gaps, fog_escalation 0.9-1.0
Parameter rationale
hold VPD-high stress below 1.5h without all-day aggressive misting
cap peak indoor VPD below ~1.8 kPa during noon-15:00
avoid heat stress while allowing short humidity recovery cycles
reduce over-humidification and water use after peak
prevent heater→vent oscillation overnight

🌆 Evening Cycle (3:36 PM) — iris-20260503-1538
validated
7/10
none recorded
Result: End-of-day score 74.9 with 70.4% both-axis compliance. Temp compliance was strong at 86.1%; VPD compliance was the bottleneck at 75.5%, dominated entirely by VPD-low stress (4.43h) with 0h heat, cold, or VPD-high stress. The cloud-deviation relaxation prevented renewed high-VPD after the afternoon correction and kept peak VPD controlled at 1.78 kPa, but the remaining posture was still too humid for too long. Cost was excellent at USD 1.07, well below the USD 4.56 7-day average; energy/water were not the limiting factor.

Previous hypothesis: Tonight’s main challenge is not condensation; it is avoiding heater→vent oscillation while conserving the humidity already built up after a water-heavy dry day. Dew-point margin is currently 7.0°F with a 5.3°F daily minimum, so I am widening overnight mist thresholds/gaps and using bias_cool +3 to +3.5 to stop small heat overshoots from dumping humidity through the vent. Before sunrise I pivot back toward dry-day readiness because tomorrow’s forecast has RH 6-10% and a midday VPD ramp despite cloud uncertainty.

}Result: End-of-day score 74.9 with 70.4% both-axis compliance. Temp compliance was strong at 86.1%; VPD compliance was the bottleneck at 75.5%, dominated entirely by VPD-low stress (4.43h) with 0h heat, cold, or VPD-high stress.

Cost was excellent at USD 1.07, well below the USD 4.56 7-day average; energy/water were not the limiting factor. Score: 7/10
New finding: Cloud-deviation relaxation was directionally correct, but on collapsed-solar days the planner should suppress humidification more decisively and earlier when VPD is already near/below band to avoid multi-hour VPD-low stress. → Added to Lessons Learned
Hypothesis
Testing: Cloud-deviation relaxation: when solar collapses and VPD is already low/near band, switch from dry-day aggressive misting to evening-style thresholds immediately. Expected outcome: Keep additional Sunday VPD-low stress under 0.5h after 15:40 while preventing VPD-high from exceeding 2.0 kPa if clouds persist.
