Result: 2026-05-01 finished planner_score 65.2, both-axis compliance 65.5%, temp compliance 83.8%, VPD compliance 76.2%. Stress was heat 4.93h, cold 0.0h, VPD-high 4.40h, VPD-low 3.73h. Cost was USD 5.39 (USD 3.63 gas, USD 1.76 electric), above the USD 4.92 7-day average; kWh 15.88 below 7d avg 21.4, therms 4.371 below 7d avg 5.061. Mister use was 110 gal. Hypothesis partially failed: VPD-high was expected under 2.5h but reached 4.4h and peak VPD 3.51 kPa; heat stress also appeared as solar peaked higher than forecast (1059 W/m2 vs 883). Cold control succeeded with 0h cold stress. Dew-point risk stayed low (0.2h, min margin 4.0F), so the limiting failure was not over-condensation but insufficient hot-dry suppression plus late-day over-humidification.

Previous hypothesis: Frost-risk overnight with the greenhouse already in heater mode. The main challenge is holding a safe seedling/orchid floor without creating heater→vent oscillation or condensation. I am keeping humidity hardware effectively quiet overnight, using modest heat bias plus low gas-stage delta, and holding a raised cooling bias so any heater overshoot does not immediately dump heat through ventilation. Friday’s late-morning handoff is included as a dry-solar fallback until sunrise replanning refreshes the day.

}Result: 2026-05-01 finished planner_score 65.2, both-axis compliance 65.5%, temp compliance 83.8%, VPD compliance 76.2%. Stress was heat 4.93h, cold 0.0h, VPD-high 4.40h, VPD-low 3.73h.

Dew-point risk stayed low (0.2h, min margin 4.0F), so the limiting failure was not over-condensation but insufficient hot-dry suppression plus late-day over-humidification. Score: 5/10
New finding: Clear spring days with solar near or above 900 W/m2 and outdoor RH near 10% need earlier, more aggressive preconditioning than 20s mist gaps and fog_escalation_kpa 0.30 alone. Use fog_escalation_kpa 0.20-0.25, engage/all near 1.1/1.5 before the 09:00 ramp, and keep sealed-vent duration short to avoid heat trapping; watch for late-day VPD-low overshoot. → Added to Lessons Learned
Hypothesis
Testing: Early dry-day preconditioning: lower mist/fog thresholds before the 10:00-13:00 VPD ramp to see whether VPD-high stress stays under 2.5h without dew-point risk. Expected outcome: Today should finish above 70% both-axis compliance, VPD-high stress under 2.5h, cold stress under 1h after sunrise, dp_risk_hours 0, and cost lower than the frost-heating morning trajectory once bias_heat steps down.
Conditions (structured)
64.0°F
11.0%
883.0 W/m²
17.0%
clear cold morning followed by very dry solar peak; forecast RH falls to 11-12% from 14:00-18:00 with solar above 800 W/m2 at peak
Expected stress windows
hold mild bias_heat 1.5 only through frost recovery, then step down to 0
mister_engage_kpa 1.25, all 1.75, 20s gap, vpd_weight 2.5, fog_escalation_kpa 0.30 during solar peak
carry dry-day posture into Saturday with engage 1.15, all 1.65, 20s gap, fog_escalation_kpa 0.25
Parameter rationale
reduce gas-driven cost after sunrise while keeping cold stress under 1h
start humidity correction before the 9-13h VPD ramp and keep VPD-high stress below 2.5h
increase evaporative cadence during peak dry air without extending sealed-vent heat trapping
use fog as the high-leverage VPD tool and keep peak VPD below 2.0 kPa indoors
tighten VPD recovery during solar peak while maintaining dp_risk_hours at 0
reduce non-safety transition churn without blocking heat flushes

Hypothesis
Testing: Overnight heat-stability reset plus Saturday dry-ramp preconditioning: correct invalid delay setpoints and test whether early aggressive mist/fog keeps Saturday VPD-high stress below 3h without dew-point risk. Expected outcome: Overnight: cold_stress <1.5h, dp_risk_hours 0, no heater→vent oscillation. Saturday daytime: VPD-high stress <3h despite RH 8-13% and solar near 900 W/m2.
