Midnight Posture00:01TRANSITIONacked-00:02Acknowledged: Midnight transition checked: greenhouse is stable in IDLE with heat1 cycling, vent/fans/fog/misters off, temp 64.0F, VPD 0.41 kPa, RH 79%, dew-point margin 6.5F. Active overnight plan already suppresses humidification and preserves heating/anti-condensation posture ahead of the 05:30 waypoint; no tunable change needed. Resolved 00:02 MDT.
New forecast data00:19FORECASTacked-00:20Acknowledged: Forecast update reviewed against active plan iris-20260503-1958: midday remains overcast but dry, peak temp about 73°F and RH ~19%, which is within the existing Monday moderate-dry posture and below the >5°F/significant-shift threshold. No tunable or plan change needed. Resolved 00:20 MDT.
New forecast data01:19FORECASTacked-01:20Acknowledged: Forecast update matches governing plan assumptions closely enough: Monday remains cool/overcast with a brief dry midday VPD window already covered by the 08:00 moderate-dry waypoint, and the evening cold/wet front remains covered by the 20:00 conservative overnight waypoint. No tunable changes needed. Resolved 01:20 MDT.
New forecast data02:19FORECASTacked-02:21Acknowledged: Forecast matches the active 05-03 sunset plan: Monday remains overcast with a brief dry midday shoulder already covered by the 08:00 moderate-dry waypoint, then a cold/wet Monday night posture already begins at 20:00. No tunable change needed on this forecast update. Resolved 02:21 MDT.
New forecast data03:20FORECASTacked-03:21Acknowledged: Forecast update matches the active 2026-05-03 sunset plan: Monday remains overcast but dry with a midday 74F/16% RH VPD peak, followed by a cold wet overnight drop. Existing 08:00 moderate dry-day posture and 20:00 overnight suppression/heating posture are still appropriate; no significant temp/cloud/humidity shift requiring tunable changes. Resolved 03:21 MDT.
New forecast data04:20FORECASTacked-04:20Acknowledged: Forecast update matches the active Monday posture closely: peak ~76°F, RH minimum 15-17%, mostly overcast with a short solar break around 13:00, and the 08:00 waypoint already lowers mist/fog thresholds for the dry midday window. No significant >5°F temperature shift, no clear/overcast regime reversal, and no tuning change needed. Resolved 04:20 MDT.
Pre Dawn04:57TRANSITIONacked-04:58Acknowledged: Pre-dawn conditions are stable: 63.9°F, VPD 0.52 kPa, RH 74%, IDLE with vent/fog/misters off and heaters active. Current plan already has a 05:30 pre-dawn heating/cool-bias waypoint and an 08:00 dry-day ramp for the forecast RH drop, so no immediate tunable change is needed. Resolved 04:58 MDT.
New forecast data05:20FORECASTacked-05:20Acknowledged: Forecast update matches the governing plan: overcast but dry midday still calls for the scheduled 08:00 moderate-dry posture, with overnight cold/wet suppression already covered. No significant temperature, cloud, humidity, or wind shift requiring tunable changes. Resolved 05:20 MDT.
Morning planning cycle05:56SUNRISEplan_writteniris-20260504-055606:00Wrote public plan iris-20260504-0556. Resolved 06:00 MDT.
New forecast data06:20FORECASTacked-06:20Acknowledged: Forecast update matches the sunrise plan assumptions: dry overcast daylight with limited solar, then cold/wet frontal passage overnight. Existing waypoints already ramp mist/fog moderately during the dry window and suppress humidification tonight, so no tunable change needed. Resolved 06:20 MDT.
New forecast data07:19FORECASTacked-07:20Acknowledged: Forecast update checked against active plan iris-20260504-0556. Temperature and humidity pattern are consistent with the existing dry-overcast/cold-front posture; cloud cover remains overcast rather than a regime shift. Solar is lower than the sunrise hypothesis, but current VPD is near/low band and the active plan already avoids the extreme dry preset and suppresses humidification tonight. No tunable change needed. Resolved 07:20 MDT.
New forecast data08:20FORECASTacked-08:21Acknowledged: Forecast update reviewed against active plan iris-20260504-0556. New 24h forecast remains within the existing hypothesis: dry but overcast daylight (peak ~75F, RH min ~16%, solar peak ~435 W/m2) followed by the cold wet front overnight. No >5F temperature shift, no clear/overcast regime change, and no humidity/solar pattern change large enough to justify replacing the current 72h plan. Resolved 08:21 MDT.
New forecast data09:20FORECASTacked-09:22Acknowledged: Forecast update reviewed: near-term forecast remains within the sunrise plan envelope. Midday solar risk is somewhat higher than the structured hypothesis, but the existing 10:00 and 13:00 waypoints already step into the intended dry-window posture (engage 1.5→1.4 kPa, gap 35→30s, fog escalation 0.4) and overnight/Tue cold-wet suppression remains appropriate. Current greenhouse is humid/low-normal VPD, so adding more humidification now would increase VPD-low risk. Resolved 09:22 MDT.
New forecast data10:20FORECASTacked-10:22Acknowledged: Forecast update checked: next 24h is still within the governing plan's expected pattern — dry midday overcast with modest solar breaks, then cold/wet low-VPD front overnight. Peak temp is only ~2F above plan, RH is somewhat drier but current/13:00 waypoints already use moderate aggressive mist/fog posture, and evening/Tue suppression remains appropriate. No tunable changes needed. Resolved 10:22 MDT.
New forecast data11:21FORECASTacked-11:23Acknowledged: No setpoint change needed. New 24h forecast is directionally consistent with active plan: midday remains dry with a slightly stronger solar break (RH 14%, solar 583 W/m²) already covered by the 13:00 moderate dry-ramp waypoint, then the forecast still collapses into cold/wet low-VPD conditions tonight. Current greenhouse is stable in IDLE at 73.7°F / 1.09 kPa with safe dewpoint margin, so changing now would risk overcorrecting. Resolved 11:23 MDT.
New forecast data12:20FORECASTacked-12:21Acknowledged: Forecast update is directionally consistent with the active plan: still overcast/cold-front dominated, with a slightly drier and brighter 13:00-14:00 window already covered by the upcoming moderate dry-ramp waypoint (engage ~1.4, gap 30, fog_escalation 0.4). Current greenhouse VPD and temperature remain controlled, so no tunable change needed. Resolved 12:21 MDT.

The active 17:00 waypoint already relaxed humidification (engage 1.8, all 2.3, gap 50, fog escalation 0.7), and 20:00 further suppresses mist/fog for the wet cold front. No tunable change needed. Resolved 17:31 MDT.

Current/future plan already suppresses humidification starting 20:00 and preserves anti-oscillation heating bias; no significant forecast shift requiring tunable changes. Resolved 17:32 MDT.
New forecast data18:21FORECASTacked-18:22Acknowledged: Forecast update matches the existing cold-wet frontal plan: tonight/Tue remain overcast, saturated, and cold with low VPD, and the active 20:00/06:00 waypoints already suppress humidification while preserving heat/anti-oscillation posture.

Previous hypothesis: Sunset overnight posture: tonight’s main challenge is not heat but the combination of current low VPD/high RH, a marginal dew-point buffer, and enough overnight cooling to invite heater→vent chatter if cooling bias is too tight. I am suppressing mist/fog overnight, holding bias_cool at +3 to +3.5 during heating windows, keeping sealed-mist caps short, then switching Monday morning to a moderate dry-day posture for the forecast 75°F / 15% RH shoulder without repeating the over-humidification mistake from May 2. Expected result: keep dp_risk_hours near 0 overnight, reduce additional VPD-low stress below 0.5h after sunset, avoid cold-stress from vent oscillation, and keep Monday’s midday VPD-high stress under ~2h despite dry outdoor air. Result: The plan successfully managed temperature and prevented daytime VPD-high stress. However, the heavy cloud cover and high humidity (89-100% RH) led to significant VPD-low stress (5.03 hours) as the transition to the cold wet front occurred. The ‘moderate dry ramp’ hypothesis was too aggressive for the actual saturation, failing to prevent the humidity surge when the sun remained obscured. Cost was slightly elevated due to heating needs, but within reasonable bounds for the season. Score: 5/10

New finding: When forecast cloud cover is near 100% and outdoor RH is high (>80%), a ‘moderate dry ramp’ can lead to massive VPD-low overshoot. In these conditions, it is safer to pre-emptively raise VPD thresholds (mister_engage_kpa) or increase the mister pulse gap earlier in the day to avoid a humidity surge when the sun stays behind clouds. → Added to Lessons Learned

Hypothesis

Testing: Moderate dry-overcast ramp: use engage 1.4-1.55 / gap 30-40 / fog_esc 0.35-0.45 today instead of the extreme dry preset, then suppress humidification hard ahead of the wet cold front. Expected outcome: Target Monday score >70, VPD-high stress <1.0h, VPD-low stress <2.0h after 06:00, cost <USD 4 through the daytime; Tuesday may spend gas but should avoid cold stress and condensation risk.

vpd_highmedium · 2026-05-04T09:00:00-06:00 to 2026-05-04T17:00:00-06:00

moderate misting: engage 1.45-1.55 kPa, gap 30-40s, fog escalation 0.35-0.45 only during the dry window

vpd_lowmedium · 2026-05-04T20:00:00-06:00 to 2026-05-05T18:00:00-06:00

raise mist thresholds to 2.4-2.5 kPa, widen gap to 60s, fog escalation 1.0, preserve heat/anti-oscillation bias

Parameter rationale

mister_engage_kpa2.0 → 1.45; outdoor VPD 1.7-2.3 kPa from 09:00-17:00 with RH 17-21%

prevent daytime VPD-high stress from exceeding 1.0h without triggering yesterday's multi-hour VPD-low overshoot

mister_pulse_gap_s55.0 → 30.0; short solar breaks near 13:00 and 15:00 can spike VPD even under cloud cover

hold VPD below 1.8 kPa during solar breaks while using moderate thresholds to avoid continuous misting

fog_escalation_kpa0.8 → 0.35; midday outdoor RH minimum 17% but solar peak only 423 W/m2

allow fog assist only if misting cannot control dry stress, target VPD-high stress under 1.0h

mister_engage_kpa1.45 → 2.5; cold wet front after 20:00, RH 63-100%, VPD 0.53 down to near zero Tuesday

reduce VPD-low stress versus yesterday's 4.43h and keep dew point risk under 0.25h

bias_cool3.5 → 4.0; overnight/tomorrow outdoor 32-40F and wet; vent-after-heat oscillation is more damaging than a small warm bias

avoid cold stress and heater→vent cycling through the frontal passage

Previous hypothesis: Monday is a misleading dry-overcast day: outdoor RH falls to 17-21% from 09:00-17:00, but forecast cloud cover stays ~95-100% with only two possible solar breaks. Yesterday proved the bigger risk under collapsed solar is VPD-low overshoot, so today’s plan uses a moderate dry ramp rather than the extreme dry preset, then strongly suppresses humidification into the cold wet front tonight and Tuesday. Result: [backfill] avg compliance 56.7% (stress 13.0 h) over plan window 2026-05-05 03:05 → 2026-05-08 03:13 Score: 3/10

Expected outcome: Minimize cold stress and VPD-low stress during the overnight frost risk window, while maintaining heating efficiency.

Reflection

Validating previous cycle: iris-20260504-0556

Result: The previous plan (iris-20260504-2108) aimed to handle the overnight frost risk (32F) and heavy cloud cover/high humidity. The forecast shows 100% cloud cover and very low VPD (0.01-0.1 kPa) throughout the day, which will almost certainly lead to significant VPD-low stress if not managed. The temperature is also forecast to stay low (36-43F range). Yesterday’s failure was primarily VPD-low stress (5h) due to high humidity. The current plan’s mitigation (bias_heat 2.0) is helpful for temp, but the humidity will be the main driver. Score: 5/10

Hypothesis

Expected outcome: Maintain temperature above 50F despite 32F frost risk and prevent VPD-low stress overnight from high humidity/cloud cover.
