Previous hypothesis: Thursday forecast shifted significantly harder: 75°F peak (vs ~68-70°F planned), 11% RH, 20+ mph wind. Starting aggressive misting 1h earlier (09:00), tightening gap to 15s at peak, shortening thermal relief to 60s to minimize dry-air flush, and maintaining aggressive settings through evening (18:00). Wednesday transitions unchanged — fog_esc 0.4 experiment Day 3 proceeds as designed. Friday cold front (32°F, snow) gets full heating posture. Result: [backfill] avg compliance 9.8% (stress 15.4 h) over plan window 2026-04-15 09:42 → 2026-04-17 01:43 Score: 1/10

Hypothesis

Testing: fog_esc 0.4 experiment Day 3 continues (Wed 13:00-18:00). Thursday is extreme stress test: 78°F/7% RH (harder than prior forecast of 75°F/11%). Extended aggressive window tests whether sustained misting through sunset prevents VPD blowout on ultra-dry evenings. Expected outcome: Wednesday: combined VPD stress < 5h, fog_esc 0.4 clean test under 66°F/15% clear conditions. Thursday: accept 6-10h VPD_high stress as physics-limited (78°F/7% extreme), but extended window should keep VPD_high < 8h vs prior plan’s potential 10h+ from early step-down. Water 350-450 gal Thursday. Friday: heating-dominated, zero VPD stress, gas cost USD 6-8. 72h total cost USD 16-22.

Previous hypothesis: Wednesday and Thursday transitions unchanged — fog_esc 0.4 experiment Day 3 (Wed clear-sky 66°F/14% RH) and extreme stress test (Thu 76°F/8% RH) continue. Friday refinement: replaced two identical stubs with four targeted transitions tracking the storm’s progression. Key change: Fri 13:00 storm arrival (34°F/95% RH/snow) bumps bias_heat to 5.0 with shorter heater cycling (min_heat_off 180s vs 300s) for efficient sustained cold operation. Fri 20:00 deep cold (31°F→25°F, clearing) maintains maximum heating. Cold outdoor air at 32°F/95% RH heats to only ~28% RH at 58°F indoor — VPD won’t crash dangerously low despite high outdoor RH. Main risk is radiative cooling after skies clear at 20:00 with 25°F lows. Gas heater at 54K BTU handles 33°F ΔT easily (~15,800 BTU/hr loss vs 54,000 capacity). Result: Score 17.3, compliance 9.5%. VPD compliance was excellent at 93.1% — fog_esc 0.4 experiment performed well on a moderate day. However, temp compliance collapsed to 9.8% with 21.58h cold stress. Root cause: crop profile band temp_low is set high enough that normal morning ramp-up (63-74°F from 7AM-11AM) and overnight temps (59-62°F) all register as cold stress. This is a band calibration issue, not a heating failure — the greenhouse was never dangerously cold. VPD-high stress only 0.92h, VPD-low 0.73h. Water 434 gal (high, 214 gal misting). Cost USD 7.71 (above USD 5 target, driven by gas heating USD 2.11 + water USD 2.10). South probe offline all day (null data). Score: 4/10

New finding: Cold stress hours are dominated by crop profile band alignment, not actual plant danger. When temp_low from crop profiles exceeds the greenhouse’s natural morning ramp-up temperature (63-68°F for most spring mornings), cold_stress accrues for hours even though conditions are safe. The planner score is structurally capped by this band mismatch. Need to either adjust crop profile temp_low to match realistic greenhouse thermal behavior, or accept cold_stress as informational rather than actionable on mornings where the greenhouse is warming naturally. → Added to Lessons Learned

Hypothesis

Testing: fog_esc 0.4 experiment Day 3 continues on Wednesday (moderate conditions, engage 1.4/gap 25-30s). Thursday is the ultimate stress test: 78°F/7% RH with fog_esc 0.4 and maximum misting aggression. If Wednesday VPD-low < 1h (moderate settings) and Thursday VPD-high < 8h (extreme physics-limited), fog_esc 0.4 is confirmed as all-conditions default. Expected outcome: Wednesday: compliance >55%, VPD_low < 1h (improved over yesterday’s 1.93h), cost < USD 5, water 150-200 gal. Thursday: compliance 30-40% (physics-limited by 78°F/7% RH), VPD_high 4-8h accepted, heat_stress 2-4h, water 350-450 gal, cost USD 8-12. Friday: heating-dominated, compliance 40-60%, cold_stress 2-4h from slab lag, cost USD 8-12 (gas-heavy). 72h total cost USD 20-28.

Previous hypothesis: Three-day posture: (1) Wednesday moderate-dry (68°F/13% RH) — moderately aggressive misting with fog_esc 0.4 experiment Day 3, using engage 1.4/gap 30s at peak to avoid yesterday’s VPD-low over-humidification while still managing dry air. (2) Thursday extreme-dry (78°F/7% RH) — maximum misting aggression with 900s sealed vent, engage 1.3/gap 15s, accepting heat stress as physics-limited. This is the ultimate fog_esc 0.4 stress test. (3) Friday cold front (36°F/rain-snow) into Saturday freeze (26°F) — full heating posture with bias_heat +5 and wide hysteresis to prevent oscillation and build slab thermal mass. Overnight cold stress diagnosis: today’s partial shows 17h cold stress because the 63.7°F nighttime band floor exceeds heat1’s 5,120 BTU capacity against 47°F outdoor. Increasing bias_heat to +3 tonight to trigger heat2 earlier. Result: Overnight portion only (plan started 7:43 PM Apr 15, still governing today). Overnight temps held 60-62°F — below crop band temp_low 63.7°F, generating cold stress as expected from band alignment lesson. VPD compliance excellent overnight (0.43-0.53 kPa, well in band). Heating posture correct — bias_heat ramped from +1 to +5, both heaters cycled appropriately. Gas heater used efficiently. Cost through 6 AM already USD 7.63 (heating-dominated: gas USD 4.02, electric USD 2.56). dp_margin safe at 9.6°F. The experiment (fog_esc 0.4 Day 4 ultimate extreme test at 76°F/7% RH) is TODAY — this evaluation covers only overnight. Will re-evaluate tonight after the daytime stress test. Score: 5/10

New finding: Overnight heating with bias_heat +3 to +5 successfully maintained 60-62°F against 44-52°F outdoor (8-18°F retention above outdoor), but still falls short of the 63.7°F crop band floor. This confirms the band alignment lesson — spring overnights structurally generate cold stress when crop profiles set temp_low above the greenhouse’s natural equilibrium. → Added to Lessons Learned

Hypothesis

Testing: fog_esc 0.4 Day 4 — ultimate extreme test. Thursday 77°F/7% RH with maximum misting aggression. If combined VPD stress under 8h, fog_esc 0.4 is confirmed as all-conditions default. Friday/Saturday are heating-dominated (no misting experiment possible). Expected outcome: Thursday: VPD-high stress 4-8h (physics-limited at 7% RH), water 300-450 gal, VPD compliance 30-50%. Friday: near-zero VPD stress, high gas usage (4-6 therms), temp compliance limited by morning ramp. Saturday: heating tapering, slab recovery. 72h total cost USD 16-22 (Thursday water + Friday/Saturday gas). Combined planner scores structurally limited to 20-40 range due to band-driven cold stress on morning ramps (lesson #91).
