Hypothesis

Conditions: Dry day forecast (11% outdoor RH, 82F). Tighten mist cycling from 45s to 30s gap before VPD ramp. Engage/all thresholds already at minimums from prior plan.

Friday March 27

Primary crop-band changes:

08:00low 58

Morning warmup underway, restore normal heating threshold.

Tactical tunable changes:

06:00engage 1.2; all 1.5; gap 30

Aggressive all-zone rotation early — dry conditions will pus

09:00pulse 120

Keep pulse duration at 120s (max effective without pooling)

16:00pulse 90

Afternoon — VPD declining, shorten pulse to reduce water use

18:00engage 1.4; all 1.8; gap 45

Evening — relax all-zone rotation threshold from minimum 1.5
