Previous hypothesis: Saturday is the first genuinely severe dry-air day after Friday’s VPD-low miss. The plan keeps dawn guarded while indoor VPD is still low, then ramps hard before the 10:00-17:00 RH 8-23% / solar 570-900 W/m² window. Experiment: sharply time-gated dry-day posture — aggressive only during confirmed dry solar stress, then fast evening reset to avoid another saturated night.

Hypothesis

Expected outcome: Manage the high-VPD, high-solar Sunday by proactively lowering misting thresholds early in the morning to buffer the steep VPD ramp, while also preparing for the afternoon heat with an earlier cooling bias. Target: VPD compliance >80% and minimize VPD-high stress.

Changed parameters

none recorded

Result: Daily scorecard 2026-05-10: planner_score 49.6, both-axis compliance 39.9%, temp compliance 65.5%, VPD compliance 44.3%. Stress was entirely VPD-low at the daily level (13.23h), with no heat/cold/VPD-high stress in the rollup; the plan-window scorecard for iris-20260510-0556 showed VPD-high mitigation succeeded (about 0.11h, well under the <2h prediction) but VPD-low remained dominant (about 6.90h in-window, 13.23h daily). Cost was low at USD 1.72, below the USD 5.62 7d average, but mister-only water was high at 485 gal versus 277 gal 7d total-water average while the total water meter read 0 gal, indicating water telemetry split should be interpreted carefully. Dew-point margin dipped to 4.2F with 2.8h dp_risk, so the evening unwind was not strong or early enough after aggressive mist/fog despite the dry-window success. Outcome is scored 5/10: good VPD-high control and low cost, but poor both-axis compliance and VPD-low domination missed the main overnight recovery objective.

Reflection

Validating previous cycle: iris-20260509-2004

Previous hypothesis: Manual recovery write because the SUNSET trigger had already timed out before MCP accepted the plan. Same plan intent: suppress overnight mist/fog after VPD-low and dew-point-risk hours, use bias_cool +3 to prevent heater→vent oscillation, then delay Sunday dry-day support until the live morning ramp.

Result: Daily scorecard 2026-05-10: planner_score 49.6, both-axis compliance 39.9%, temp compliance 65.5%, VPD compliance 44.3%. Stress was entirely VPD-low at the daily level (13.23h), with no heat/cold/VPD-high stress in the rollup; the plan-window scorecard for iris-20260510-0556 showed VPD-high mitigation succeeded (about 0.11h, well under the <2h prediction) but VPD-low remained dominant (about 6.90h in-window, 13.23h daily).

Outcome is scored 5/10: good VPD-high control and low cost, but poor both-axis compliance and VPD-low domination missed the main overnight recovery objective. Score: 5/10

New finding: After a humid dawn/day, even when midday VPD-high is controlled, aggressive mist/fog can leave enough moisture carryover that evening recovery must start earlier and more strongly; monitor dp_margin and VPD-low by sunset, not only overnight. → Added to Lessons Learned

Hypothesis

Testing: Earlier two-step evening unwind after moderate dry-day support. Expected outcome: Planner score >63, both-axis compliance >60%, VPD-high stress <2.0h, VPD-low stress <6.0h, dp_risk_hours <1.5h, cost <USD 5.50.

Parameter rationale

mister_engage_kpa1.37 → 1.2; outdoor VPD rises from 1.08 at noon to ~1.99 by 17:00 with solar 529-884 W/m2

hold VPD-high stress under 2.0h

mister_pulse_gap_s48.33 → 25.0; moderate dry window RH 21-32%, not Saturday's 8-16%

recover rising VPD without carrying aggressive gaps into evening

fog_escalation_kpa0.8 → 0.25; post-PR-A vent+fog support during 12:00-17:00 solar peak

keep peak VPD near or below 2.2 kPa

mister_vpd_weight1.6 → 2.3; south/west dry first under clear solar and south misters are highest-effect

prioritize productive zones

fog_escalation_kpa0.25 → 0.8; Saturday produced 13.5h VPD-low after late aggressive posture

cut overnight VPD-low below 6h and dp_risk below 1.5h

Reflection

Daily Summary So Far — this cycle will be validated at the next planning cycle.

Hypothesis

Testing: Overnight suppression plus early dry-ramp handoff: keep dp_risk <1h tonight, then start Monday support before 09:00 instead of reacting at late morning peak. Expected outcome: Tonight: no dew-point margin below 5F for more than 1h and cold_stress under 1h. Monday before sunset: VPD-high stress lower than Sunday despite worse forecast, accepting heat stress as physics-limited.

Conditions (structured)

Outdoor peak

88.0°F

RH minimum

5.0%

Solar peak

898.0 W/m²

Cloud average

18.0%

clear dry night falling to 46F, then severe hot-dry Monday with outdoor RH 5-10% and VPD 3.2-4.3 kPa from noon through early evening

Expected stress windows

vpd_lowmedium · 2026-05-10T21:00:00-06:00 to 2026-05-11T07:30:00-06:00

wide mist thresholds, 60s gap, short sealed window, high fog escalation while fog is time-window blocked

vpd_highhigh · 2026-05-11T09:30:00-06:00 to 2026-05-11T19:30:00-06:00

early morning engage drop to 1.25, peak engage 1.05, 15-20s gaps, fog escalation 0.15, south/west weighting

heathigh · 2026-05-11T12:00:00-06:00 to 2026-05-11T18:00:00-06:00

bias_cool -1 during severe solar load, d_cool_stage_2 3, accept physics-limited overshoot rather than extending sealed mist

Parameter rationale

bias_cool2.0 → 3.0; overnight 46-60F with heaters likely and recent cold_stress 0.8h

reduce heater-to-vent oscillation overnight without changing crop bands

mister_engage_kpa1.75 → 1.65; current VPD ~1.0 kPa with safe dew margin but prior 3.02h VPD-low and 2.8h dp risk

avoid unnecessary overnight misting unless the greenhouse dries materially

mister_pulse_gap_s60.0 → 60.0; overnight humidity holds better and fog is blocked until 07:00

prevent VPD-low recurrence and keep dew-point-risk under 1h

fog_escalation_kpa0.8 → 0.15; Monday 11:00-18:00 forecast RH 5-16%, outdoor VPD 2.6-4.3 kPa, solar peak ~898 W/m2

bring vent+fog assist online during the severe dry window and reduce VPD-high stress versus Sunday

mister_vpd_weight1.5 → 2.8; south/west dry first in solar load and south misters are most productive

spend water on the driest/productive zones instead of center-zone waste

Setpoints

Reflection

Daily Summary So Far — this cycle will be validated at the next planning cycle.

Hypothesis

Testing: planning gateway validation smoke: verify set_plan persistence, dispatcher handoff, and ESP32 readback with a single complete overnight waypoint. Note: requested plan_id prefix iris-validation-* was rejected by MCP validation, so canonical iris-YYYYMMDD-HHMM was used. Expected outcome: Within the 21:00-03:00 validation window, no unnecessary mist/fog cycles, dew-point margin remains safe, and all 24 emitted Tier-1 tunables receive controller readback confirmation.

overnight validation window only, ~21:00-03:00 MDT; outdoor cools from 60F to 49F with no solar and indoor VPD already low-normal at ~0.43-0.61 kPa

Expected stress windows

vpd_lowmedium · 2026-05-10T21:00:00-06:00 to 2026-05-11T03:00:00-06:00

suppress misting with engage 1.70 kPa, all 2.35 kPa, 60s gaps, short sealed window, and fog escalation high while fog is time-window blocked

coldlow · 2026-05-11T00:00:00-06:00 to 2026-05-11T03:00:00-06:00

bias_heat +1.0 and bias_cool +3.0 to keep overnight heating stable without triggering avoidable vent churn

Parameter rationale

mister_engage_kpa1.65 → 1.7; current indoor VPD 0.43-0.61 kPa and forecast night has no solar with outdoor VPD falling toward 0.60 kPa by 03:00

avoid validation-window misting unless the house dries materially; keep VPD-low/dew-point-risk from worsening

mister_all_kpa2.35 → 2.35; overnight no-solar window with current humid air and previous VPD-low/dew-point-risk lessons

prevent all-zone escalation overnight

mister_pulse_gap_s60.0 → 60.0; nighttime humidity retention is adequate and fog is blocked outside 07:00-17:00

preserve dew-point margin and minimize water use during the smoke test

fog_escalation_kpa0.8 → 0.8; fog time window blocks fog overnight; high escalation avoids accidental early fog before morning handoff

no fog use during the six-hour validation period

bias_heat1.0 → 1.0; outdoor falls from 60F to 49F by 03:00 with recent cold_stress 0.8h

maintain mild overnight heat support without changing crop bands

bias_cool3.0 → 3.0; overnight heater cycles are likely and vent oscillation should be avoided

delay non-safety cooling and reduce heater-to-vent churn
