Midnight Posture00:00TRANSITIONacked-00:01Acknowledged: Midnight check: greenhouse is stable in IDLE at 63.6F, VPD 0.47 kPa, RH 76%, dew-point margin 7.5F. Heat1 is trimming temperature, vent/fans/fog/misters are off, and the active overnight plan already holds a humidity-conserving posture until the 04:30/06:30/09:00 dry-ramp waypoints. No tunable change needed. Resolved 00:01 MDT.
New forecast data00:40FORECASTacked-00:41Acknowledged: 00:40 forecast update reviewed against active plan iris-20260502-1958. Near-term temperature and RH remain within the plan envelope (peak ~77F, RH floor 6%, dry ramp 09:00-19:00). Cloud/solar guidance has shifted lower, but that reduces heat-trap risk while the very low RH still justifies the existing 09:00 aggressive VPD preconditioning waypoint. No tunable changes needed. Resolved 00:41 MDT.
New forecast data01:41FORECASTacked-01:42Acknowledged: Forecast update reviewed: new 24h forecast matches the active plan posture—very dry Sunday ramp (RH 6-10%, VPD near 3 kPa) with moderated/overcast solar. Existing 06:30 and 09:00 waypoints already pivot from overnight humidity conservation into aggressive VPD preconditioning (lower engage/all thresholds, short mist gap, high VPD weighting, low fog escalation). No significant temperature, humidity, or cloud-cover shift requiring a new plan. Resolved 01:42 MDT.
New forecast data02:40FORECASTacked-02:41Acknowledged: No tunable change needed: refreshed 24h forecast still matches the active plan's premise—very dry Sunday RH/VPD ramp with substantial cloud uncertainty and reduced but nonzero solar. Existing 06:30 and 09:00 waypoints already pivot from overnight humidity conservation to aggressive mist/fog preconditioning for the dry ramp; lower updated solar reduces heat-trap risk rather than requiring immediate retune. Reassess at sunrise with observed cloud/solar. Resolved 02:41 MDT.
New forecast data03:41FORECASTacked-03:42Acknowledged: Forecast update reviewed: 24h forecast still matches the active overnight-to-dry-ramp plan closely enough to leave it in place. Today remains a very dry Sunday with RH falling to 7-10% and peak temp near 78F; midday cloud cover is high but solar/VPD ramp still warrants the already-scheduled aggressive 06:30/09:00 mist/fog posture. No tunable changes needed. Resolved 03:42 MDT.
New forecast data11:18FORECASTacked-11:19Acknowledged: Forecast update reviewed: next 24h remains the expected hot-dry Sunday ramp (RH 8-12%, VPD 2.5-3.0 kPa through afternoon) already covered by the active aggressive dry-day posture: mister_engage_kpa 1.1, mister_all_kpa 1.5, 20s pulse gap, fog_escalation_kpa 0.22, short 180s sealed-vent cap, and dwell gate enabled. Current greenhouse is stable (76.1F, VPD 1.19, dp margin 14.1F), so no tunable or plan change needed. Resolved 11:19 MDT.
New forecast data12:18FORECASTacked-12:18Acknowledged: Forecast update matches the active 11:32 plan: near-term peak remains ~78F with RH 8-11%, strong solar through mid-afternoon, and the plan already holds aggressive mist/fog until 17:00 before relaxing to avoid VPD-low overshoot. No significant temp/cloud/humidity shift requiring tunable changes. Resolved 12:18 MDT.
New forecast data13:18FORECASTacked-13:19Acknowledged: Forecast update reviewed: next 24h remains aligned with active plan iris-20260503-1132 — short dry-solar peak this afternoon (78F, RH 7-9%, solar falling after 15:00) followed by planned evening relaxation and Monday overcast/cold-front posture. No significant >5F temperature shift or humidity/solar pattern change requiring a new plan. Resolved 13:19 MDT.

Peak Stress14:58TRANSITIONacked-14:59Acknowledged: Peak-stress transition reviewed with fresh climate/equipment/plan/setpoint data. Current avg VPD is 1.07 kPa against 0.8-1.1 band, temp 77.6F against temp_high 78F, equipment is idle, and south zone is already humid/low-VPD. Existing aggressive peak posture is sufficient; further mist/fog aggression would risk repeating yesterday's VPD-low/water overshoot. No tunable change needed. Resolved 14:59 MDT.

New forecast data16:18FORECASTacked-16:19Acknowledged: Forecast update reviewed against active plan and current setpoints. Near-term Sunday is dry but solar is collapsing and fog window is ending; the 15:38 cloud-deviation relaxation remains appropriate. Monday still has a dry midday shoulder, but the existing 07:00 waypoint already tightens mist/fog thresholds for that window and the 16:00 relaxation matches improving RH/low solar. No significant forecast shift requiring tunable changes. Resolved 16:19 MDT.
Tree Shade16:58TRANSITIONacked-16:59Acknowledged: Tree Shade transition reviewed: greenhouse is cool and stable in IDLE (72.0F, VPD 0.80 kPa, RH 70%), vent/fog/misters are off, and the active 15:38 cloud-deviation plan has already relaxed mist/fog posture with a further evening relaxation scheduled at 20:00. Current VPD is above the low band but below mist thresholds, so additional tuning would mainly increase VPD-low/overshoot risk. No setpoint change needed. Resolved 16:59 MDT.
New forecast data17:19FORECASTacked-17:19Acknowledged: Forecast update reviewed: next 24h still matches the active posture — relaxed evening/overnight thresholds after the cloud-deviation plan, then aggressive Monday morning VPD controls for the dry 10:00-15:00 window. Current greenhouse is cool/humid and idle, so no tunable changes needed. Resolved 17:19 MDT.
New forecast data18:19FORECASTacked-18:20Acknowledged: Forecast update matches the assembled context and active plan: dry but mostly overcast Monday midday is already covered by the 07:00 aggressive VPD waypoint, with relaxation at 16:00 before the cold/wet Tuesday pattern. Current greenhouse is stable (70.7F, VPD 0.56, IDLE), so no tunable change needed. Resolved 18:20 MDT.
Decline18:58TRANSITIONacked-18:58Acknowledged: Decline transition checked at 18:58 MDT: greenhouse is IDLE with all cooling/misting/fog/vent off, temp 68.0F, VPD 0.49 kPa, RH 79%, dew point margin 6.6F. Current plan already relaxes further at 20:00 for evening; no immediate tunable change needed because solar is nearly gone, fog is outside its time window, and VPD is low/near band rather than high. Resolved 18:58 MDT.
New forecast data19:19FORECASTacked-19:20Acknowledged: Forecast matches the active plan assumptions: Monday remains overcast but very dry (RH ~15-23%, VPD peak ~2.5 kPa) with modest solar and temps below heat-risk levels. Existing 07:00 waypoint already tightens mist/fog thresholds for the dry midday window, then relaxes at 16:00. No tunable change needed. Resolved 19:20 MDT.

New forecast data20:18FORECASTacked-20:19Acknowledged: Forecast update reviewed: new 24h forecast still matches active sunset plan assumptions — cool overnight, dry overcast Monday with a brief midday solar/VPD shoulder, then colder wet conditions Monday night. Existing 08:00 dry-day waypoint already lowers mister thresholds and fog escalation enough for the forecast shift; no tunable change needed. Resolved 20:19 MDT.
Evening Settle20:58TRANSITIONacked-20:58Acknowledged: Evening settle check: greenhouse is stable in IDLE/heating posture (65.1F, VPD 0.40 kPa, RH 81%, dew point margin 6F). Fog/misters/vent/fans are off; heat1 is cycling as expected for the cold-front overnight. Active sunset plan already suppresses humidification overnight with high mist thresholds, wide VPD hysteresis, short sealed-vent cap, and elevated cooling bias. No tunable change needed; no Slack post required. Resolved 20:58 MDT.
New forecast data21:19FORECASTacked-21:20Acknowledged: Forecast update reviewed: next 24h remains aligned with active sunset plan iris-20260503-1958. Monday still shows overcast/low-solar but dry midday air (peak ~73F, RH ~18-24%, VPD ~2.25 kPa), followed by humid/cool evening and rain risk. Existing 08:00 moderate dry-day posture and 20:00 relaxation already cover this; no tunable change needed. Resolved 21:20 MDT.
New forecast data22:19FORECASTacked-22:19Acknowledged: Forecast update matches the active sunset plan: Monday remains overcast, moderately warm (peak ~74F), dry midday (RH ~17-20%), and cold/wet Monday night. Existing 08:00 moderate dry-ramp and 20:00 overnight anti-condensation/heating posture already cover the shift; no tunable or waypoint change needed. Resolved 22:19 MDT.
New forecast data23:19FORECASTacked-23:20Acknowledged: Forecast update checked: the 24h outlook remains aligned with active plan iris-20260503-1958 — Monday still shows a brief dry midday shoulder near 76F/16% RH under mostly overcast conditions, followed by the expected cold/wet night. Existing 08:00 dry-ramp and 20:00 overnight suppression waypoints already cover this; no tunable change needed. Resolved 23:20 MDT.

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: [backfill] avg compliance 70.4% (stress 4.4 h) over plan window 2026-05-03 17:26 → 2026-05-04 02:00 Score: 6/10

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.

Parameter rationale

mister_engage_kpa1.1 → 1.15; RH 8-12% and outdoor VPD 2.6-3.0 kPa from 12:00-17:00

hold VPD-high stress below 1.5h without all-day aggressive misting

fog_escalation_kpa0.22 → 0.2; post-PR-A fog helps during VENTILATE in dry solar conditions

cap peak indoor VPD below ~1.8 kPa during noon-15:00

mist_max_closed_vent_s180.0 → 150.0; solar 780-881 W/m2; avoid heat trapping while sealing

avoid heat stress while allowing short humidity recovery cycles

vpd_hysteresis0.35 → 0.4; yesterday had 4.0h VPD-low after aggressive extension

reduce over-humidification and water use after peak

bias_cool0.0 → 3.0; overnight 48-60F and Monday/Tuesday cold front

prevent heater→vent oscillation overnight

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. 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.

Previous hypothesis: Sunday is a short, sharp dry-solar VPD event rather than a heat emergency: forecast peaks near 78°F, outdoor RH bottoms near 8%, VPD reaches ~3.0 kPa, and solar is strong through mid-afternoon. I am keeping aggressive fog/mist only through the solar peak, then relaxing earlier than yesterday to avoid repeating the 4.0h VPD-low / high-water overcorrection. Overnight and the Monday-Tuesday cold/wet front shift conservative on misting and warmer on bias_cool to prevent heater→vent humidity dumps. Result: [backfill] avg compliance 70.6% (stress 5.0 h) over plan window 2026-05-04 02:00 → 2026-05-05 03:05 Score: 6/10

Hypothesis

Testing: Sunset anti-condensation + Monday moderate-dry ramp: suppress overnight humidification, then use fog_escalation 0.4 / engage 1.5 for a 75F, 15% RH but overcast day. Expected outcome: dp_risk_hours ≤0.1 overnight, post-sunset vpd_low_stress <0.5h, Monday midday vpd_high_stress <2h, total cost below the 7d average USD 4.56 unless Monday night heating dominates.
