Fixed Midnight00:00TRANSITIONacked-00:01Acknowledged: Midnight transition. Conditions are stable (Temp 62.6F, VPD 0.46 kPa). Current heating is active to maintain temp. No immediate need for setpoint changes. Resolved 00:01 MDT.
New forecast data00:38FORECASTacked-00:39Acknowledged: Forecast update received. Current conditions and forecast show a gradual temperature ramp (32F to 70F) and VPD rise (0.09 to 2.04 kPa) throughout the day. The previous plan (iris-20260505-0718) already addressed cold/saturated conditions with high mister_engage_kpa and heat bias. No significant shifts in trend or immediate stress escalation requiring new setpoints are detected at this time. Resolved 00:39 MDT.
New forecast data01:38FORECASTacked-01:38Acknowledged: Forecast indicates cold, overcast, and humid morning. Current greenhouse conditions (62.6°F, 0.49 kPa VPD) are stable within the band. No significant deviations in forecast require immediate setpoint changes; the existing plan for high humidity management remains valid. Resolved 01:38 MDT.
New forecast data02:38FORECASTacked-02:39Acknowledged: Forecast remains consistent with current plan. No significant shifts in temperature, cloud cover, or humidity patterns to warrant a new plan. Continuing with existing posture. Resolved 02:39 MDT.
New forecast data03:38FORECASTacked-03:38Acknowledged: Forecast for the next 24h shows relatively stable conditions with a mild temperature ramp (37°F to 70°F) and a VPD peak of 2.05 kPa. Current setpoints (bias_heat=2.0, mister_engage_kpa=1.8) and the existing posture are sufficient to manage the predicted diurnal ramp. No significant deviations from the current operating logic are required at this time. Resolved 03:38 MDT.
New forecast data04:38FORECASTacked-04:38Acknowledged: Forecast for the next 24h matches the current posture. Temperatures are ramping up slowly (from 40°F to 70°F), and VPD is expected to rise from 0.4 to 2.0 kPa. The current setpoints (bias_heat=2.0, increased mister engagement) are already managing the transition from the cold, saturated overnight. No immediate change to the plan is required. Resolved 04:38 MDT.
New forecast data05:38FORECASTacked-05:38Acknowledged: Forecast shows cloud cover remaining high (99-100%) and no significant temperature or humidity shifts that would invalidate the current posture. Current ambient conditions (T: 64.8F, VPD: 0.52 kPa) are well within the current band. No actionable changes needed. Resolved 05:38 MDT.

Forecast shows rising VPD and temp throughout the morning, but current humidity is sufficient. No immediate tunable adjustments required for the transition. Resolved 06:07 MDT.
New forecast data06:38FORECASTacked-06:39Acknowledged: Forecast analysis shows relatively stable spring morning conditions. Current indoor temperature (64F) and VPD (0.52 kPa) are within band limits. The planned posture from the previous cycle (iris-20260505-0718) focused on suppressing VPD-low stress with high engagement thresholds; however, current conditions are currently managed by the dispatcher without immediate need for significant waypoints...

Previous hypothesis: SUNRISE catch-up recovered from planner context overflow. The local run already diagnosed saturated/overcast conditions and wrote tactical one-shot knobs: bias_heat=2.0, mister_engage_kpa≈2.04, mister_pulse_gap_s=60. This full plan formalizes that posture with complete Tier 1 coverage and exact trigger correlation. Result: 2026-05-07 finished with planner_score 59.5, both-axis compliance 57.4%, temp compliance 72.1%, VPD compliance 65.4%. Stress was entirely VPD-low: 6.43h low-VPD, 0h VPD-high, 0h heat, 0h cold. Cost was acceptable at USD 4.80, split nearly evenly between electric (USD 2.52) and gas (USD 2.28), with therms 2.751 below the 7d avg 5.905 and kWh 22.71 slightly above 7d avg 21.1. The plan correctly avoided VPD-high stress and kept cost under target, but afternoon/overnight humidity controls were still too wet: the 30s pulse-gap dry-window posture and fog availability over-corrected into sustained VPD-low. Dew point margin reached 4.2F with 1.7h dp-risk, so the disease/condensation edge was worse than intended. Forecast solar was badly undercalled (598 predicted vs 1097 actual), but actual humidity stayed much wetter than the dry forecast, making the aggressive afternoon humidity posture unnecessary. Score: 5/10

New finding: On cool/mild days with indoor RH already high and forecast uncertainty large, prioritize avoiding VPD-low over preempting dry-window VPD-high unless outdoor RH is actually below ~30% and indoor VPD is rising. Use wider mister gaps and conservative fog until live VPD exceeds the ramp threshold. → Added to Lessons Learned

Hypothesis

Testing: Staged humidity response: conservative misting through the humid morning, lower thresholds/faster gap only during the 14:00-17:30 dry window, then overnight mist suppression. Expected outcome: Target planner_score >65, both-axis compliance >65%, VPD-low stress <1.5h, VPD-high stress <1.0h, total cost below USD 7 if gas demand eases overnight.

vpd_lowhigh · 2026-05-07T21:00:00-06:00 to 2026-05-08T07:00:00-06:00

raise mist thresholds, max pulse gap, fog conservative, slight negative heat bias to avoid gas-heavy humidity chasing

Parameter rationale

mister_engage_kpa1.8 → 1.6; current RH 71% and VPD 0.89 at 09:46

avoid adding moisture during the already humid morning

mister_engage_kpa1.6 → 1.35; outdoor RH 22-29% and VPD 1.5-2.0 from 13:00-17:00

start VPD recovery before crop-band excursions compound

fog_escalation_kpa0.5 → 0.35; dry afternoon but moderate temperature peak only 71F

allow vent+fog assist if VPD rises while avoiding prolonged sealed heat trapping

mister_pulse_gap_s60.0 → 30.0; afternoon VPD peak near 2.0 kPa with cloud-filtered solar

reduce VPD-high stress below 1h without creating overnight VPD-low

bias_heat0.0 → -1.0; gas cost yesterday 8.453 therms vs 7d avg 5.39 and overnight outdoor VPD near 0.1-0.4

reduce gas-heavy humidity chasing overnight while keeping safety rails intact

Previous hypothesis: Morning plan for a cool, cloudy-but-drying May 7: avoid repeating yesterday’s saturated/VPD-low posture in the morning, then step into moderate VPD protection during the 13:00-17:00 dry window without overusing gas or trapping heat. Experiment: staged mist/fog posture — conservative before noon, aggressive enough in the dry afternoon, then suppress overnight misting to reduce VPD-low and condensation risk.
