Midnight Posture00:00TRANSITIONacked-00:01Acknowledged: Midnight transition checked live climate, equipment, active plan, and setpoints. Current state is stable for the frost-adjacent overnight posture: 62.3F, VPD 0.43 kPa, dew-point margin 7.0F, vent/fog/misters off, heaters active as expected. Existing plan already raises pre-dawn heating bias and delays cooling before the 35F forecast low, with mist/fog suppressed overnight. No tunable change needed. Resolved 00:01 MDT.
New forecast data00:35FORECASTacked-00:36Acknowledged: Forecast update matches the active sunset plan: cold/cloudy overnight, cool overcast morning, and only a modest midday dry window with peak outdoor temp ~61F and mixed/mostly cloudy solar. Current conditions are stable in IDLE at 64.8F / 0.59 kPa with safe dew-point margin, and existing waypoints already relax from overnight anti-oscillation into moderate midday dry-window posture. No tunable or plan change needed. Resolved 00:36 MDT.
New forecast data01:36FORECASTacked-01:36Acknowledged: Forecast update matched the active sunset plan posture: cold/cloudy overnight, modest midday dry window with intermittent solar, and no >5F temperature or major humidity shift requiring waypoint changes. Current compliance is acceptable (74.7% both-axis, VPD 0.50 kPa, dew-point margin 8.0F), so no tunable changes were made. Resolved 01:36 MDT.
New forecast data02:35FORECASTacked-02:36Acknowledged: Forecast update reviewed at 02:35 MDT. New 24h forecast matches the active sunset plan assumptions: pre-dawn low near 35F, mostly overcast/cool morning, brief midday dry/solar window around 14:00-15:00, then cloudy/cool evening. Current waypoints already hold a warmer anti-oscillation overnight posture and moderate midday dry-window posture; no significant >5F temperature, cloud-regime, wind, or humidity shift requires a setpoint change. Resolved 02:36 MDT.
New forecast data03:35FORECASTacked-03:36Acknowledged: 03:35 forecast update checked against active sunset plan iris-20260428-1953. Next-24h forecast remains aligned with the current posture: cold/overcast pre-dawn, modest midday dry window near 61-63F with RH 24-33% and intermittent solar, then cooler humid overnight. Existing 07:00 and 12:00 waypoints already cover the needed transition from overnight anti-oscillation/heating posture to moderate dry-window misting readiness... Resolved 03:36 MDT.
New forecast data04:35FORECASTacked-04:36Acknowledged: Forecast update reviewed against active plan iris-20260428-1953. Next 24h remains aligned with the existing posture: cool morning, modest midday dry window peaking ~63F / 24-30% RH with intermittent solar, then colder overcast overnight. Existing 07:00 and 12:00 waypoints already cover this without requiring tunable changes. Resolved 04:36 MDT.
Pre Dawn05:03TRANSITIONacked-05:03Acknowledged: Pre-dawn conditions are within the intended overnight posture: indoor 63.9F, VPD 0.48 kPa, dew-point margin 7.9F, vent/fog/misters off, heaters cycling as expected against 38.7F outdoor air. Existing sunrise and midday waypoints already transition from warm anti-oscillation posture to moderate dry-window posture; no tunable change needed. Resolved 05:03 MDT.
New forecast data05:36FORECASTacked-05:37Acknowledged: 05:36 forecast update matches the active sunrise/midday posture: today remains mild (peak ~62F) with a modest dry/solar window around 14:00-15:00 and a cold, humid front tonight. Existing plan already delays cooling overnight, suppresses mist/fog while cool, and relaxes to moderate dry-window settings at noon. No >5F temp shift or material humidity/solar change requiring new tunables. Resolved 05:37 MDT.

New forecast data06:36FORECASTacked-06:37Acknowledged: 06:36 forecast update matches the 06:08 sunrise plan: cool peak near 62F, mixed cloud/solar with a brief dry window around late morning to midafternoon, and wet/cold overnight front still expected. Existing waypoints already keep fog conservative and misting moderate for VPD-low risk while allowing midday readiness; no tunable or plan change needed. Resolved 06:37 MDT.
New forecast data07:35FORECASTacked-07:36Acknowledged: Forecast update checked against active plan iris-20260429-0608. New 24h forecast remains within the plan envelope: peak temp 64F vs planned 62F, solar peak 707 W/m² vs planned 792, and the drier RH minimum (~20%) occurs mostly late day with falling/zero solar. Existing 11:00-14:00 moderate dry-window waypoints already lower mister thresholds and keep fog conservative; evening/night waypoints remain appropriate for the cold wet front. No tunable or plan change needed. Resolved 07:36 MDT.
New forecast data08:36FORECASTacked-08:37Acknowledged: Forecast update reviewed: next 24h remains aligned with active plan iris-20260429-0608. Outdoor RH is a bit drier than the sunrise hypothesis, but peak temp remains cool (~63F) and the current 11:00/14:00 waypoints already cover the brief dry/solar window with moderate mist readiness while preserving yesterday's VPD-low discipline. Current indoor VPD is in/near band and scorecard shows VPD compliance strong, so no tunable changes needed. Resolved 08:37 MDT.
New forecast data09:36FORECASTacked-09:36Acknowledged: Forecast update reviewed: temperature remains within the active plan envelope, solar peak is similar to the sunrise plan, and the drier afternoon RH shift is already covered by the 11:00/14:00 moderate dry-window mist posture plus 17:00 humidity-discipline reset. No tunable change needed. Resolved 09:36 MDT.
New forecast data10:36FORECASTacked-10:37Acknowledged: Forecast update reviewed against active plan iris-20260429-0608 and current setpoints. Near-term temp peak remains cool/moderate (64F vs planned ~62F), solar peak is essentially unchanged (~805 W/m2 vs planned 792), and current 11:00/14:00 waypoints already cover the dry midday window with moderate mist readiness. RH is drier than the sunrise hypothesis late afternoon, but indoor VPD is currently in band and the 17:00 relaxation coincides with low solar; no tunable change justified yet. Resolved 10:37 MDT.
New forecast data11:36FORECASTacked-11:36Acknowledged: Forecast update matches the active cool mixed-cloud plan: peak temp still ~63F, short 14:00-15:00 solar/dry window remains covered by the 14:00 waypoint, and overnight/Thursday remains cool-cloudy/wet. No significant >5F temperature shift or humidity/cloud pattern change requiring tunable changes. Resolved 11:36 MDT.
New forecast data12:36FORECASTacked-12:37Acknowledged: Forecast update checked against active plan and current setpoints. No significant shift requiring a new plan: next 24h remains cool/mostly cloudy with only a brief moderate solar/dry window this afternoon, and the existing 14:00 onward waypoints already relax aggressive mist/fog posture and move to conservative wet/cool overnight settings. Resolved 12:37 MDT.
New forecast data13:36FORECASTacked-13:37Acknowledged: Forecast update matches the active cool/mixed-cloud plan: peak outdoor temp still ~62F, dry window remains limited to midafternoon, and cloud cover trends overcast after 15:00. Current greenhouse is stable in IDLE at 77.5F / 1.19 kPa with no dew-point risk, so no tunable or plan change needed. Resolved 13:37 MDT.
New forecast data14:36FORECASTacked-14:38Acknowledged: Forecast update matches the current cool/cloudy plan: near-term peak remains ~62°F with RH 25-33% through the short late-afternoon dry window, then overcast/cool conditions overnight into tomorrow. Current greenhouse is stable (74.9°F, VPD 0.88 kPa, IDLE, no dew point risk). Existing waypoints already shift from moderate dry-window posture at 17:00 to conservative humid/cold-night posture at 20:00 and 06:00, so no tunable change is warranted. Resolved 14:38 MDT.
Peak Stress14:58TRANSITIONacked-14:59Acknowledged: Peak-stress transition checked: greenhouse is stable/idle at 76.8°F, avg VPD 1.07 kPa inside the current 0.8–1.1 band, dew-point margin 12.3°F, all cooling/humidity equipment off, and the 17:00 waypoint already backs down toward the evening posture. No tunable change needed; avoid extra mist/fog because south VPD is already low at 0.64 kPa. Resolved 14:59 MDT.
New forecast data15:36FORECASTacked-15:37Acknowledged: Forecast update reviewed against active plan and current setpoints. New 24h forecast remains cool/overcast with falling overnight VPD and no significant warm/clear shift; existing evening/overnight waypoints already widen fog/misting posture and bias heat for the cool front. No tunable or plan change needed. Resolved 15:37 MDT.
New forecast data16:36FORECASTacked-16:37Acknowledged: Forecast update reviewed against active plan and current setpoints. Near-term forecast remains cool/overcast with low solar, outdoor VPD mostly below 1.25 kPa, and current greenhouse conditions are stable (71.4F, VPD 0.72, IDLE). Existing plan already shifts to conservative humidity posture at 17:00/20:00 and overnight; no significant temperature, cloud, wind, or humidity shift requiring tunable changes. Resolved 16:37 MDT.
Tree Shade16:58TRANSITIONacked-16:58Acknowledged: Tree-shade transition checked: greenhouse is stable/cooling (68.6F, avg VPD 0.86 kPa, IDLE), misters/fog/vent are off, and the active 17:00 posture already raises mist thresholds, widens gap, and keeps fog conservative for the evening humidity rise. No tunable change needed. Resolved 16:58 MDT.
New forecast data17:36FORECASTacked-17:37Acknowledged: Forecast update reviewed: next 24h remains cold/overcast/wet with low solar and low outdoor VPD; active plan already shifts to conservative high mist/fog thresholds at 20:00 and 06:00. No significant forecast delta requiring tunable changes. Resolved 17:37 MDT.
New forecast data18:36FORECASTacked-18:37Acknowledged: Forecast update reviewed: next 24h remains the expected cold/cloudy/wet regime with overnight low near 40-41°F, saturated cloud cover, low outdoor VPD, and no meaningful solar/dry heat window. Current plan already has conservative humid/cold-night posture with wide mist thresholds, 60s gap, fog_escalation_kpa 1.0, and elevated heating bias. Current greenhouse is stable at 67.1°F, VPD 0.49 kPa, mode IDLE, dew point margin 6.9°F. No tunable change needed. Resolved 18:37 MDT.
Decline18:54TRANSITIONacked-18:54Acknowledged: Decline transition checked: avg temp 65.8°F and VPD 0.50 kPa are in band, equipment is in safe evening posture with heat1 maintaining the lower band, vent/fog/misters off, and the active plan already has a 20:00 evening waypoint for cooler humid conditions. No tunable change needed. Resolved 18:54 MDT.
New forecast data19:37FORECASTacked-19:37Acknowledged: Forecast update matches the existing plan posture: cold/wet/cloudy overnight and Thursday with low outdoor VPD, followed by the already-covered Friday dry ramp. Current plan keeps mist/fog conservative and heat bias elevated; no significant >5F temperature, cloud-regime, or humidity shift requiring a tunable change. Resolved 19:37 MDT.

Previous hypothesis: Sunset plan: tonight’s main challenge is frost-adjacent heating and heater/vent oscillation, not VPD-high stress. Outdoor air drops to 35°F by 06:00 with high RH and heavy cloud cover; current indoor dew-point margin is safe at 8.4°F, but late-night outdoor VPD collapses below 0.15 kPa. I am biasing warmer before pre-dawn, delaying cooling with bias_cool +4, keeping gas staging available, and suppressing mist/fog overnight. Expected outcome: cold stress under 3h, no dew-point risk hours, gas cost below the 7-day average, and no repeat of rapid heater→vent cycling. Tomorrow midday gets a moderate dry-window posture because forecast briefly reaches 61°F/28% RH with possible solar, but this is not an aggressive hot-dry setup. Result: [backfill] avg compliance 74.3% (stress 6.9 h) over plan window 2026-04-29 12:04 → 2026-04-30 01:55 Score: 6/10

Hypothesis

Testing: Cool-day humidity discipline: avoid repeating yesterday’s VPD-low overshoot by keeping fog conservative and mist thresholds moderate except during the brief 11:00-15:30 dry window. Expected outcome: Target >60% both-axis compliance, <1.5h VPD-high, <2h VPD-low, no dew-point risk hours, and total cost below the 7-day average (USD 6.99).

Validating previous cycle: iris-20260428-1953

Result: 2026-04-29 finished at planner_score 68.4 with 73.7% both-axis compliance. Temp compliance 86.3% and VPD compliance 84.7%; VPD-low stress dominated at 1.6h, with 0.0h heat/cold/VPD-high stress in the frozen daily summary. The plan’s conservative fog/mist posture successfully avoided the predicted midday VPD-high breakout even though actual solar exceeded forecast materially (1218 vs 792 W/m²), but it still produced more VPD-low stress than the <1h target. Utility cost was USD 7.90, above the USD 6.99 7-day average, driven roughly equally by electric (USD 3.61) and gas (USD 3.95), while water use was low at 70 gal vs 211 gal 7-day average. Score: 7/10

New finding: On cool, cloudy spring days with crop-band vpd_high near 0.7 kPa, conservative fog and long mist gaps prevent VPD-high breakouts but can still leave 1-2h VPD-low stress; keep fog escalation conservative, avoid vpd_hysteresis values that are not confirmed by firmware, and bias toward ventilation/dehumidification rather than extra misting unless observed VPD is rising. → Added to Lessons Learned

Hypothesis

Testing: Cool-day humidity discipline: avoid repeating yesterday’s VPD-low overshoot by keeping fog conservative and mist thresholds moderate except during the brief 11:00-15:30 dry window. Expected outcome: Target >60% both-axis compliance, <1.5h VPD-high, <2h VPD-low, no dew-point risk hours, and total cost below the 7-day average (USD 6.99).

Reflection

Validating previous cycle: iris-20260429-0608

Previous hypothesis: Cool, mixed-cloud spring day with a short dry/solar window. Yesterday’s miss was not high-VPD control; it was over-humidification, so today I’m keeping fog conservative, bringing unconfirmed high thresholds back into confirmed ranges, and using moderate midday mist readiness only when observed VPD actually rises. Result: [backfill] avg compliance 69.3% (stress 1.7 h) over plan window 2026-04-30 01:55 → 2026-05-01 01:56 Score: 7/10

Hypothesis

Testing: Overnight anti-oscillation posture: positive heat bias + wide cooling bias + dwell gate ON during a 39°F humid night. Expected outcome: By sunrise: dp_risk_hours remains 0, dew point margin stays above 5°F, total additional cold stress stays below ~2h, and vent/heater cycling is lower than today’s 42 heat1 / 67 heat2 transition pattern.
