Hypothesis

Testing: Use a live-VPD bridge: low-wet through dawn, then enable band-coupled assist only after the dry ramp is observed. Expected outcome: Avoid overnight VPD-low stress; hold dew risk at 0h and reduce controller-attributable VPD-high stress below 0.5h.

Cloud average

Cool humid pre-dawn, then clear dry solar ramp; live VPD gates wet assist after the prior forecast miss.

Expected stress windows

vpd_lowhigh · 2026-09-20T01:00:00-06:00 to 2026-09-20T07:00:00-06:00

Suppress wet assist; retain heat and dew margin with conservative exchange.

vpd_highhigh · 2026-09-20T10:00:00-06:00 to 2026-09-20T17:00:00-06:00

Use live-edge band-coupled wet assist; shorten pulse gap only after VPD confirms.

Parameter rationale

mister_pulse_gap_s45.0 → 20.0; Corrected VPD climbs 0.82 to 1.75 from 10:00-15:00; apply after live confirmation.

Keep VPD-high recovery available without pre-wetting the cold dawn.

fog_escalation_kpa0.4 → 0.2; Solar peaks 713 W/m2 and RH falls to 36-39% in the 13:00-17:00 window.

Bring heavy assist in earlier during hot-dry venting while preserving dew margin.

temp_hysteresis1.0 → 1.5; Outdoor temperature bottoms near 51-52F with high RH before sunrise.

Reduce heater/vent churn and prevent cold slugs.

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

Hypothesis

Testing: Test a live-VPD bridge: keep dawn low-wet, open assist near the active high edge, and taper only after measured recovery. Expected outcome: Keep dawn dew-risk hours at 0, avoid VPD-low stress before 10:00, and reduce controller-attributable VPD-high stress below 0.75h.

Solar peak

Cloud average

Cool humid dawn, dry solar ramp through late afternoon, humid recovery after 20:00; use live VPD gating.

Expected stress windows

vpd_highhigh · 2026-09-20T11:00:00-06:00 to 2026-09-20T18:00:00-06:00

Live-edge assist: engage excess 0.05, all-zone 0.25, fog excess 0.18.

vpd_lowhigh · 2026-09-20T22:00:00-06:00 to 2026-09-21T06:00:00-06:00

Taper wet duty after recovery; preserve drying exchange and dew margin.

Parameter rationale

mister_engage_kpa1.6 → 1.25; Corrected VPD rises from 0.77 at 09:00 to 1.84 at 16:00.

Start wet assist at the active high edge without repeating the wet dawn drift.

fog_escalation_kpa0.4 → 0.18; Dry peak is forecast 13:00-18:00 with RH 33-43% and solar up to 688 W/m2.

Make heavy assist available earlier while dew margin remains at least 8F.

temp_hysteresis1.0 → 1.5; Dawn is 51F outdoors with high RH and prior overnight wet-band alerts.

Reduce heater/vent and wet-mode whipsaw during the cold humid recovery.
