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. 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. 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.

Parameter rationale

bias_heat2.0 → 0.0; outdoor warms from 34F at 07:00 to 53F by 10:00 after frost risk passes

reduce gas-driven cost after sunrise while keeping cold stress under 1h

mister_engage_kpa2.5 → 1.25; RH falls below 25% by 11:00 and below 15% after 14:00

start humidity correction before the 9-13h VPD ramp and keep VPD-high stress below 2.5h

mister_pulse_gap_s60.0 → 20.0; solar 829-883 W/m2 with outdoor VPD 1.35-1.83 kPa

increase evaporative cadence during peak dry air without extending sealed-vent heat trapping

fog_escalation_kpa1.0 → 0.3; post-PR-A fog can run during VENTILATE at vpd_high_eff + delta; hot-dry stress is expected despite cool outdoor air

use fog as the high-leverage VPD tool and keep peak VPD below 2.0 kPa indoors

vpd_hysteresis0.5 → 0.35; dry clear peak with low condensation risk; yesterday had only mild VPD-low

tighten VPD recovery during solar peak while maintaining dp_risk_hours at 0

sw_dwell_gate_enabled1.0 → 1.0; dry-solar day risks mode whipsaw; THERMAL_RELIEF is exempt in shipped firmware

reduce non-safety transition churn without blocking heat flushes

Previous hypothesis: Clear, dry Friday needs a fast pivot from frost recovery to dry-solar VPD control. I am dropping heat bias after sunrise to stop gas spend, keeping dwell gate on for stability, and moving mist/fog readiness earlier than the VPD ramp. Expect VPD, not temperature, to be today’s bottleneck; dew-point risk should stay near zero because outdoor air dries sharply. Result: [backfill] compliance unavailable over plan window 2026-05-02 01:58 → 2026-05-02 12:02 Score: 4/10

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.

Vision observation notes
Canna LiliesGemini Vision notes

Foliage looks green and robust, no obvious signs of stress.

Vanda OrchidsGemini Vision notes

Hanging orchids appear healthy, though visibility is somewhat obscured by mist/fog.

lettuceGemini Vision notes

Seedlings appear healthy with no visible signs of stress.

pepperGemini Vision notes

Seedlings appear to be growing normally, but image quality makes detailed assessment difficult.

strawberryGemini Vision notes

Seedlings appear healthy and are establishing well.
