Result: Plan-window metrics for iris-20260513-0547 show 46.8% both-axis compliance, 48.6% temp compliance, 61.4% VPD compliance, cost USD 1.71, heat stress 3.94h, cold stress 0.32h, VPD-high stress 2.76h, VPD-low stress 0.01h. Daily rollup later shows score 59.5, compliance 55.0%, heat stress 7.77h and VPD-high stress 5.45h. The severe-day plan was correct to keep sealed windows capped at 180s and to use band-coupled moisture support; it preserved VPD-low and cost/water bounds, but the physics-limited cooling lesson dominated: temp compliance became the main bottleneck and heat stress remained high despite earlier ventilation/fan staging. Dew safety was mostly preserved but not perfect, with daily min dp margin 4.4F and 0.5h dp risk.

Reflection

Validating previous cycle: iris-20260512-2007

Previous hypothesis: SUNSET overnight and Wednesday severe hot-dry handoff plan. Today’s score was weak because heat and VPD-high were co-bottlenecks; the previous plan protected dew point and limited VPD-low carryover, but moderate dry-day settings were not strong enough under surprise 1083 W/m² solar. Tonight’s objective is recovery without over-humidifying: high overnight mist thresholds, 60s gaps, short sealed windows, and bias_cool +3 to +3.5 so any heater use does not trigger vent chatter. Tomorrow is a true severe hot-dry day, so the plan starts a guarded dry ramp before the 09:00 VPD climb and uses strong but capped peak settings: early physical misting, 15s gaps, fog escalation 0.15, dwell gate on, and 180s sealed windows to avoid heat traps. Expected outcome: overnight dp_risk 0h and cold stress under 1h; Wednesday VPD-high lower than today despite worse forecast, while accepting structural heat stress around 5-8h if outdoor reaches 92F.

Result: Plan-window metrics for iris-20260513-0547 show 46.8% both-axis compliance, 48.6% temp compliance, 61.4% VPD compliance, cost USD 1.71, heat stress 3.94h, cold stress 0.32h, VPD-high stress 2.76h, VPD-low stress 0.01h. Daily rollup later shows score 59.5, compliance 55.0%, heat stress 7.77h and VPD-high stress 5.45h. The severe-day plan was correct to keep sealed windows capped at 180s and to use band-coupled moisture support; it preserved VPD-low and cost/water bounds, but the physics-limited cooling lesson dominated: temp compliance became the main bottleneck and heat stress remained high despite earlier ventilation/fan staging. Dew safety was mostly preserved but not perfect, with daily min dp margin 4.4F and 0.5h dp risk. Score: 5/10

New finding: On severe hot-dry days near 86-90F with RH below 10%, band-coupled moisture support can reduce VPD-high relative to temperature stress, but temperature compliance becomes physics-limited; keep sealed windows capped near 180s and prioritize overnight recovery plus early next-day ramp rather than extending sealed mist to chase VPD. → Added to Lessons Learned

Hypothesis

Testing: Severe-day band-coupled VPD support: use live-band moisture thresholds, 15-20s peak gaps, fog_escalation 0.20, dwell gate ON, and keep sealed windows capped at 180s instead of repeating older 900s sealed-window extreme plans. Expected outcome: For the 2026-05-13 daytime window: keep dew-point risk at 0h, keep mister water within the 500 gal budget, reduce VPD-high stress versus yesterday’s weak dry-day window despite worse forecast, and accept structural heat stress if outdoor reaches 90-92F.

Severe hot dry spring day. Forecast VPD rises above 3 kPa by 13:00 and peaks near 4.6 kPa at 15:00; solar peaks near 890 W/m2. Forecast VPD has recently overshot reality by ~0.4 kPa, but current dawn VPD is already near the crop high band with healthy 11.9F dew margin, so the plan starts support before the 09:00-12:00 ramp.

evening unwind widens hysteresis, lengthens gaps, raises fog escalation while leaving moderate mist recovery available because outdoor air remains very dry

Parameter rationale

mister_engage_kpa1.55 → 0.9; live VPD 0.79 is near current vpd_high 0.84 and forecast VPD exceeds 3 kPa from 13:00-19:00

avoid dispatcher moisture-guardrail clamps and bring physical mist support online before VPD-high accumulates

mister_all_kpa2.2 → 1.1; band-coupled guardrail recommends all-zone near vpd_high + 0.25 during near-edge VENTILATE stress

allow all-zone rotation during the severe dry peak instead of delaying it far above the crop band

mister_engage_delay_s75.0 → 30.0; RH falls from 39% at 10:00 to 9-13% at 14:00-16:00 with solar above 800 W/m2

reduce missed early VPD-high excursions during the fast ramp

mister_all_delay_s300.0 → 60.0; recent dispatcher clamps show 300s is too conservative during live VPD-high/VENTILATE stress

escalate from S1 to all-zone support within one minute during confirmed severe stress

mister_pulse_gap_s45.0 → 15.0; validated dry-day lessons recommend 15-25s gaps when RH <20% and solar >800 W/m2

speed evaporative recovery while the evening waypoint restores longer gaps to avoid overnight carryover

fog_escalation_kpa0.6 → 0.2; PR-A allows vent-fog assist at vpd_high_eff + escalation; peak forecast is 92F/9% RH

use fog as the primary high-leverage VPD assist during VENTILATE without waiting far above the band

bias_cool2.5 → -2.5; heat warning: 89-92F from 14:00-16:00 and solar 812-890 W/m2

pre-cool and ventilate earlier, accepting structural heat but minimizing avoidable overshoot

d_cool_stage_23.0 → 2.0; cooling is physics-limited; fan2 should not wait far above the shifted cooling threshold at peak

bring full ventilation support earlier during 90F outdoor heat

mist_max_closed_vent_s180.0 → 180.0; lessons 95 and 89 warn not to extend sealed windows under hot dry stress

preserve dew-point safety and avoid sealed heat traps

vpd_watch_dwell_s60.0 → 30.0; VPD ramp from 0.98 at 09:00 to 2.45 at 12:00 and 4.59 by 15:00

enter recovery sooner without turning off the dwell gate

sw_dwell_gate_enabled1.0 → 1.0; 24h equipment transitions remain high; PR #35 exempts THERMAL_RELIEF and safety from the gate

reduce mode whipsaw without blocking heat flushes

mister_vpd_weight2.0 → 3.0; south/west mister paths are the productive evaporative recovery zones under solar stress

spend water on the driest/productive zones while staying within the 500 gal mister budget

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

Hypothesis

Testing: Overnight bounded recovery after severe hot-dry day, then early Thursday dry-ramp handoff without extending sealed mist above 180s. Expected outcome: Overnight: 0 new dew-point-risk hours after plan start, cold stress under 0.5h, VPD-low under 0.5h, and VPD-high not worsening despite dry outdoor air. Thursday morning handoff: enter the 10:00 dry ramp near band with guardrail-safe moisture thresholds and cost below today’s USD 3.37 trajectory until sunrise.

Conditions (structured)

Outdoor peak

86.0°F

RH minimum

8.0%

Solar peak

822.0 W/m²

Cloud average

70.0%

Sunset follows a severe hot-dry day. Current indoor dew margin is healthy near 11F and VPD is near the active high band, while overnight outdoor air remains dry (forecast VPD 1.1-2.2 kPa) and Thursday becomes another hot-dry day. Forecast VPD historically overshoots reality by about 0.65 kPa, so the overnight plan is bounded rather than extreme, with a stronger handoff starting at dawn/10:00 if the dry ramp materializes.

Expected stress windows

vpd_highmedium · 2026-05-13T20:10:00-06:00 to 2026-05-14T02:00:00-06:00

Keep moisture thresholds near the active band but slow physical delivery: engage 0.95-1.00, all 1.15-1.20, 45-50s gaps, 60-90s engage delay, 180s sealed cap.

coldlow · 2026-05-14T03:00:00-06:00 to 2026-05-14T07:00:00-06:00

Outdoor lows stay near 60F, so use only bias_heat 0.5 and bias_cool +3 to prevent heat-to-vent chatter rather than chasing a warmer band.

vpd_highhigh · 2026-05-14T09:00:00-06:00 to 2026-05-14T19:30:00-06:00

Dawn/10:00 handoff returns to band-coupled dry-day posture: engage 0.90, all 1.10, 30-60s delays, 20-30s gaps, fog escalation 0.25-0.30, dwell gate on, sealed cap 180s.

heathigh · 2026-05-14T11:00:00-06:00 to 2026-05-14T18:30:00-06:00

Do not extend sealed mist; use bias_cool -1 at the dry-ramp handoff, summer vent gate on, d_cool_stage_2 2.5, and accept structural heat if outdoor reaches 86F.

Parameter rationale

bias_cool1.5 → 3.0; Mild 60-67F overnight with possible heater calls and current VENTILATE at 67.9F; validated sunset plans use +3 to +4 to prevent heater-to-vent chatter.

Avoid avoidable overnight vent/cold oscillation while letting the morning handoff reduce bias_cool before heat risk.

mister_engage_kpa0.87 → 0.95; Current VPD 0.75 is near vpd_high 0.82 with healthy 11F dew margin; outdoor air stays dry overnight.

Allow bounded recovery if VPD rises without requesting conservative values that dispatcher guardrails will clamp.

mister_all_kpa1.07 → 1.15; Recent clamps show all-zone values far above vpd_high + 0.25 are too conservative during near-edge VPD stress.

Keep all-zone escalation available for dry north/east pockets while avoiding daytime-style over-humidification.

mister_pulse_gap_s30.0 → 45.0; Night air holds humidity better and dp margin must remain above 5F; severe daytime 15-20s gaps are unnecessary overnight.

Limit VPD-low/dew risk while still allowing recovery from dry outdoor air intrusion.

fog_escalation_kpa0.15 → 0.7; Fog is blocked after 17:00 and not needed overnight; Thursday 10:00 handoff lowers it before the dry ramp.

Avoid stale aggressive fog posture at night while keeping morning fog assist available when the firmware window opens.

mist_max_closed_vent_s180.0 → 180.0; Lessons 95 and 89 validated today: extending sealed windows under hot-dry stress risks heat traps more than it helps VPD.

Preserve dew/heat safety and prevent sealed humidity attempts from becoming tomorrow's heat-stress driver.

vpd_hysteresis0.45 → 0.5; Overnight VPD is near band but can oscillate with dry outdoor air and short mist pulses.

Reduce mode churn and prevent overshoot into VPD-low overnight.

mister_vpd_weight2.0 → 2.0; Zone spread remains >0.5 kPa with north driest; no evidence to over-weight peak daytime zones overnight.

Keep recovery focused but not as water-intensive as severe daytime vpd_weight 3.0.
