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

Hypothesis

Testing: Test whether a directly guardrail-compatible midnight-to-daylight wet-assist posture can reduce guardrail reshaping and preserve dew safety through another severe hot-dry ramp. Expected outcome: By sunrise, dew margin remains above 8F with no cold stress; through Wednesday, VPD-high remains the bottleneck but wet/fog assist stays materialized with fewer guardrail-held rows than 2026-07-14, no dp-risk hours, and no water-budget clipping of live VPD recovery.

another clear severe hot-dry July ramp after a guardrail-heavy VPD-high day; current average VPD is served but east zone remains dry-edge and dew margin is safe

vpd_highhigh · 2026-07-15T08:00:00-06:00 to 2026-07-15T22:00:00-06:00

guardrail-compatible band-coupled wet assist: engage near vpd_high+0.05, all-zone near +0.20 to +0.25, 35-40% duty, fog escalation 0.15 during 07:00-17:00 fog window, wet recovery until measured VPD returns inside band

45 min thermal lead, strong solar precool, all-fans VENTILATE wet assist; accept structural cooling misses near 95F

vpd_highhigh · 2026-07-16T08:00:00-06:00 to 2026-07-16T22:00:00-06:00

repeat band-coupled wet/fog assist for 94F/RH 15% Thursday with no clock taper while readings remain above band

heathigh · 2026-07-17T11:00:00-06:00 to 2026-07-17T21:00:00-06:00

early pre-cool and wet VENTILATE posture for hotter Friday; expect physics-limited heat stress and protect VPD/dew safety

Parameter rationale

mister_engage_kpa0.82 → 1.27; current VPD 1.14 is near served high and east zone is 1.42 before a 95F/RH 14% dry ramp

keep S1 wet assist available near vpd_high+0.05 without relying on dispatcher guardrail correction

mister_all_kpa1.02 → 1.47; zone VPD spread exceeds 0.5 kPa and prior vent_moisture_capacity_limit alerts showed broad-house dry stress

make all-zone rotation available near vpd_high+0.20 to +0.25 during hot-dry ventilation

fog_escalation_kpa0.2 → 0.15; hot-dry VENTILATE overlaps the 07:00-17:00 fog window and fog produced the strongest recent VPD improvement prior

trigger 7x fog assist earlier during safe daylight VPD-high windows

mister_pulse_gap_s30.0 → 24.0; solar 735-903 W/m2 and RH 14-25% from late morning through afternoon

increase effective wet duty during peak VPD-high without changing crop bands

mister_water_budget_gal300.0 → 300.0; yesterday used 366 gal total and still had 7.09h VPD-high in the sunrise window

avoid clipping live VPD recovery while dew and occupancy rails are safe
