Hypothesis

Testing: Guardrail-compatible severe-day wet assist with live-ramp confirmation: suppress only the humid pre-dawn wetting, then open band-coupled mister/fog posture once VPD confirms the dry ramp, without chasing target lines inside the crop corridor. Expected outcome: By sunrise, 0 dp-risk hours and no material VPD-low accumulation; by Friday evening, VPD-high stress should be below recent 7-15h severe-day runs if wet assist materializes, while heat stress may remain high because 98-103F afternoons are physics-limited.

Conditions

Outdoor peak

103.0°F

RH minimum

13.0%

Solar peak

892.0 W/m²

Cloud average

35.0%

humid/dew-safe pre-dawn with VPD around the low edge, followed by three severe hot-dry afternoons near 98-103F, RH 13-18%, and solar near 850-900 W/m2; forecast VPD has recently overshot reality, so dry assist is staged by live ramp rather than overnight water budget alone

Expected stress windows

vpd_lowmedium · 2026-07-24T00:15:00-06:00 to 2026-07-24T08:30:00-06:00

wet/fog restraint, high dew-margin floor, stable ventilation/dehum posture when useful, and no resource spend while VPD remains below the low edge

vpd_highhigh · 2026-07-24T10:00:00-06:00 to 2026-07-24T22:00:00-06:00

band-coupled wet assist near vpd_high+0.05, all-zone near +0.20 to +0.25, fog escalation near 0.15 inside the 07:00-17:00 window, and evening recovery while dew margin stays safe

heathigh · 2026-07-24T11:00:00-06:00 to 2026-07-24T20:00:00-06:00

thermal lead, solar pre-cooling, all-fans authority, evaporative assist, and acceptance that peak heat is exhaust-capacity limited

vpd_highhigh · 2026-07-25T08:00:00-06:00 to 2026-07-25T22:00:00-06:00

repeat severe-day guardrail-compatible wet/fog posture with full water budget and low resource sensitivity

heathigh · 2026-07-25T10:00:00-06:00 to 2026-07-25T19:00:00-06:00

early thermal lead and evaporative assist; do not chase impossible target-line precision above ambient/cooling capacity

vpd_highhigh · 2026-07-26T08:00:00-06:00 to 2026-07-26T22:00:00-06:00

third severe dry day gets the same live-confirmed band-coupled wet/fog assist and evening recovery

Parameter rationale

mister_engage_kpa1.62 → 1.27; Friday 10:00-18:00 raw VPD rises from 1.75 to 4.96 kPa, with current vpd_high about 1.22 kPa and validated lessons recommending vpd_high+0.05 in hot-dry VENTILATE

make S1 moisture available near the high edge once live dry stress appears, reducing VPD-high severity without waiting for extreme excursions

mister_all_kpa1.77 → 1.47; whole-house severe dry stress is forecast for Friday through Sunday with modest zone spread, so all-zone escalation should be close to vpd_high+0.20 to +0.25

allow all-zone rotation during broad dry stress while avoiding unnecessary pre-dawn wetting

fog_escalation_kpa0.5 → 0.15; fog is the 7x moisture path and the severe dry/heat windows overlap the 07:00-17:00 fog allowance with dew margin currently safe

lower VPD-high severity during hot-dry VENTILATE when firmware dew/RH/time gates permit fog

mister_water_budget_gal100.0 → 300.0; recent low-water days did not recover corridor compliance and the next three afternoons are severe hot-dry events

avoid budget-limited VPD recovery during safe severe dry stress while still using the pre-dawn wet restraint window

mister_pulse_gap_s60.0 → 22.0; validated lessons for dry RH below 20% call for 15-25s gap, and recent guardrails repeatedly held long gaps down during VPD-high stress

keep wet duty effective and guardrail-compatible during confirmed dry stress, then let evening/dew posture taper after recovery
