Validating previous cycle: iris-20260324-1200

Previous hypothesis: (not recorded) Result: Historical plan - insufficient data for retrospective validation. Score: 5/10

New finding: No lesson extractable. → Added to Lessons Learned

Hypothesis

Conditions: Plan horizon: 20h. Tomorrow forecast: extreme — outdoor 85-89F, 10-14% RH, VPD 3.6-4.2 kPa, gusts 14-25 mph. Yesterday: 10.43h heat stress. Strategy: aggressive mister pre-position, tighter VPD ceiling, earlier all-mister engagement. East zone RH 97% / VPD 0.09 — flagged. Hydro water temp 90.1F — CRITICAL, needs human attention.

Hypothesis

Conditions: Increase burst to 90s during peak. More water per cycle = more evaporative cooling. Yesterday 10.4h VPD stress with 60s bursts — need more.

Hypothesis

Conditions: Data shows 60s is sweet spot. 90s wastes water — air saturates after 60s. 11 pulses analyzed: 60s pulse got 0.42 VPD drop vs 0.12 avg for 55s.

Hypothesis

Conditions: Peak heat defense. Outdoor forecast 87-89F/10-12%RH/VPD 3.9-4.1 through 4PM. Lower ceiling so HUMID_S1 triggers at 1.80 kPa. North already 3.04, South 2.69.
