Previous hypothesis: Aggressive pre-dawn heating bias (+1°F) with bias_cool +3°F on all cold nights will prevent vent oscillation. During daytime dry periods (Sat-Mon), early mister engagement (1.3 kPa), short pulse gaps (20-25s), extended sealed-vent time (900s on Sun/Mon), and fog escalation at 0.3 kPa will maximize humidity retention against extreme outdoor dryness. This should reduce VPD_high stress hours compared to standard posture. Result: [backfill] compliance unavailable over plan window 2026-04-11 05:57 → 2026-04-11 06:42 Score: 4/10

Hypothesis

Conditions: Three challenging days ahead: Saturday (Apr 11) overcast with 75°F peak, 18% low RH, moderate VPD stress expected 5h; Sunday (Apr 12) clear skies, 76°F peak, extreme 8% RH — worst day, 11h stress forecast; Monday (Apr 13) partly cloudy, 70°F peak, 11% low RH with high winds (20-29 mph), 9h stress. Current nighttime bands are tight (vpd_high=0.6, temp_high=65) requiring engage at 1.3 and bias_cool=+3 at all times during heating. Crop health shows lettuce/strawberry stress in east zone (nutrient/light issues outside planner control). Dew point margin healthy at 9.9°F, no condensation risk. Testing: Compare Saturday (overcast, 18% RH) vs Sunday (clear, 8% RH) with identical peak-stress tuning (engage 1.3, gap 20s, weight 3.0, max_closed_vent 900s) to isolate whether solar load or humidity deficit is the dominant VPD driver. If Sunday vpd_high_stress exceeds Saturday by >3h despite identical tuning, solar load dominates and shade cloth is the structural fix. Expected outcome: Saturday vpd_high_stress ~3-4h (midday only), Sunday vpd_high_stress ~7-9h (solar + extreme dryness), Monday vpd_high_stress ~5-7h. If Sunday exceeds Saturday by >3h with identical tuning, solar load is confirmed as dominant driver. | target_score=45 | target_compliance=45% | expected_stress=[heat=4.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 6.0

Previous hypothesis: By maintaining bias_cool=+3 during all heating periods and deploying maximum-aggression misting (engage 1.3, gap 20s, weight 2.5, sealed vent 900s) during the extreme dry afternoons of Sunday and Monday, we can reduce vpd_high stress from 34h to under 8h per day while eliminating cold stress from vent oscillation. Result: [backfill] compliance unavailable over plan window 2026-04-11 06:42 → 2026-04-11 07:27 Score: 4/10

Hypothesis

Conditions: Today (Sat) is overcast with a brief dry window 11AM-2PM (75°F, 18% RH outdoor), then clouds return with possible light rain. Sunday is the hardest day: clear skies, 76°F, 8% RH outdoor — extreme VPD stress expected for 11+ hours. Monday is windy (25-29 mph) with 70°F high and 11% RH, moderating by evening. Current nighttime VPD is 0.81-0.92 kPa against a band ceiling of 0.6 kPa — we’re already out of band. Today’s partial scorecard shows 17.3h total stress dominated by vpd_high (12.6h). East zone seedlings (lettuce, strawberry, pepper) show stress signs (wilting, yellowing, browning) — likely light/nutrient related, not directly addressable by this planner. Testing: Compare Sunday peak stress (gap=15s, fog_escalation=0.2, max_closed=900s) vs Monday peak stress (gap=20s, fog_escalation=0.3, max_closed=900s) to test whether 15s gap + 0.2 fog escalation provides meaningfully better VPD control on the drier day (8% RH Sun vs 11% RH Mon). If Sunday’s vpd_high_stress per outdoor VPD unit is lower than Monday’s, the ultra-aggressive posture justifies the water cost. Expected outcome: Sunday vpd_high_stress_h / avg_outdoor_vpd should be ≤ Monday’s ratio despite Sunday being drier, demonstrating that 15s gap + 0.2 fog escalation compensates for extreme dryness. | target_score=55 | target_compliance=55% | expected_stress=[heat=3.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: Maintaining bias_cool=+4 during all heating periods prevents the vent oscillation that caused 8.6h cold stress on April 10. Engaging misters at 1.3 kPa with 20s gap during peak dry hours (Sat-Mon) and extending mist_max_closed_vent_s to 900s on the driest days (Sun/Mon with RH 9-10%) will keep VPD closer to band despite extreme outdoor dryness.

Hypothesis

Conditions: Three challenging days ahead: Saturday (today) high 75°F with 17% RH and 100% cloud cover most of the day, Sunday extreme dry (76°F, 8% RH, clear afternoon), Monday windy and dry (70°F, 11% RH, high winds 25-29 mph). Today’s partial scorecard shows 19.3h total stress dominated by 14.6h vpd_high — the current plan’s daytime posture hasn’t engaged yet (it’s 1:25 AM). Cold nights all three days (lows 40-51°F) require heating bias. East zone seedlings (lettuce, strawberry, pepper) show stress indicators but these are likely light/nutrient issues outside tuning control. Tuesday transitions to much cooler (46°F high) with higher humidity — easy day. Testing: Compare Saturday (cloud-moderated, fog_escalation=0.3, max_closed=600, dwell=45s) vs Monday (clear+windy, fog_escalation=0.3, max_closed=900, dwell=30s) on vpd_high_stress hours. Monday is windier (25-29 mph) which increases infiltration losses. If Monday’s vpd_high_stress per outdoor VPD is comparable to Saturday’s despite worse conditions, the 900s sealed-vent + 30s dwell compensates for wind-driven humidity loss. Expected outcome: Monday’s vpd_high_stress_h / avg_outdoor_vpd ratio should be within 20% of Saturday’s ratio, demonstrating that extended sealed-vent time offsets wind-driven infiltration losses. | target_score=62 | target_compliance=65% | expected_stress=[heat=1.5, cold=0.0, vpd_high=6.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: Maintaining bias_cool=+4 during all heating periods prevents vent oscillation cold stress, while aggressive daytime misting (engage 1.3, gap 20s, weight 2.5) with extended sealed-vent time (900s) and low fog escalation (0.3 kPa) will minimize vpd_high stress on these extreme dry days. The key validated lesson is that nighttime vpd_high ~0.6 means mister_engage_kpa must be at 1.3 even overnight to have any chance of engaging before the band ceiling. Result: [backfill] compliance unavailable over plan window 2026-04-11 08:12 → 2026-04-11 08:57 Score: 4/10

Hypothesis

Conditions: Today (Sat) is cloud-moderated with high 74°F and outdoor RH dropping to 17% — moderate VPD stress expected. Sunday is the hardest day: clear skies, 76°F high, outdoor RH plunging to 8%, extreme dryness requiring maximum misting aggression. Monday is windy (25-29 mph) with 70°F high and 11% RH — wind-driven infiltration will challenge humidity retention. Tuesday brings a cold front (46°F high, 33% RH) — much easier. Current partial-day scorecard shows 15.63h vpd_high_stress already accumulated today, indicating the active plan’s daytime posture needs more aggressive misting and longer sealed-vent periods. East zone seedlings (lettuce, strawberry, pepper) show stress signs but these are likely nutrient/light issues outside this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, mist_max_closed_vent_s=900, vpd_watch_dwell_s=30, mister_pulse_gap_s=15) vs Monday (fog_escalation_kpa=0.3, mist_max_closed_vent_s=900, vpd_watch_dwell_s=30, mister_pulse_gap_s=20) on vpd_high_stress hours normalized by outdoor VPD. Sunday is drier (8% RH) but calmer; Monday is windier (25-29 mph) but slightly less dry (11% RH). If fog_escalation_kpa=0.2 on Sunday produces fewer normalized vpd_high_stress hours than 0.3 on Monday, the lower fog threshold compensates for extreme dryness better than sealed-vent alone. Expected outcome: Sunday’s vpd_high_stress_h / avg_outdoor_vpd should be lower than Monday’s ratio despite worse outdoor humidity, demonstrating that fog_escalation_kpa=0.2 provides meaningful additional humidity control beyond misting alone on extreme dry days. | target_score=55 | target_compliance=55% | expected_stress=[heat=2.0, cold=0.5, vpd_high=7.0, vpd_low=0.5] | expected_cost=USD 7.0

Hypothesis

Conditions: Today (Sat) is overcast with 75°F high, 18% low RH — moderate VPD stress expected. Sunday is the hardest day: 76°F, 7% RH, extreme dryness with clear-to-cloud transition at 11:00. Monday brings 70°F, 11% RH with high winds (25-29 mph) and cloud cover clearing at 11:00. Tuesday drops to 46°F with 33% RH — cold front arrives, minimal stress. Current partial-day scorecard shows 22.3h total stress (17.6h vpd_high + 4.7h heat) with only 7% compliance, but nighttime bands are tight (vpd_high=0.6, temp_high=65) and indoor VPD is 0.85-1.00 — the overnight band is very narrow. Lettuce and strawberry seedlings in east zone show stress (wilting, yellowing, browning) — likely nutrient/light issues outside this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, wind 3-18 mph, outdoor RH 7-15%) vs Monday (fog_escalation_kpa=0.3, wind 20-29 mph, outdoor RH 11-22%) on vpd_high_stress hours normalized by average outdoor VPD. If fog_escalation_kpa=0.2 on Sunday yields a lower stress-to-outdoor-VPD ratio than 0.3 on Monday, earlier fog engagement is the dominant lever for extreme dryness. Expected outcome: Sunday’s vpd_high_stress_hours / avg_outdoor_vpd should be lower than Monday’s ratio despite Sunday being 2x drier, demonstrating that fog_escalation_kpa=0.2 compensates for extreme dryness better than 0.3 with sealed-vent alone. | target_score=55 | target_compliance=55% | expected_stress=[heat=2.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: By maintaining bias_cool=+4 during all heating periods to prevent vent oscillation, keeping mister_engage_kpa=1.3 at all times (since nighttime vpd_high band is 0.6-0.8, well below the default 1.6 engage threshold), and using aggressive sealed-vent misting (gap=20s, max_closed=900s) during peak dry hours, we can reduce total stress hours from 69.6h to under 15h across the 3-day period. Result: [backfill] compliance unavailable over plan window 2026-04-11 09:42 → 2026-04-11 10:27 Score: 4/10

Hypothesis

Conditions: Today (Sat): overcast, high 75°F, outdoor RH dropping to 18% by 1 PM — moderate VPD stress expected. Sunday is the hardest day: clear-to-partly-cloudy, 76°F high, outdoor RH plunging to 7% with winds 14-18 mph — extreme dryness will drive sustained VPD_high stress. Monday: windy (20-29 mph), 70°F high, 11-12% RH, clearing by afternoon — still aggressive but slightly less extreme. Tuesday cold front arrives (46°F high, 33% RH) — easy day. Current partial scorecard shows 18.6h vpd_high_stress today already, indicating the active plan’s evening revert to engage=1.3/gap=45 was too conservative for the dry overnight. East zone seedlings (lettuce, strawberry) show stress signs but these are likely light/nutrient issues outside tuning scope. Testing: Compare Saturday (overcast, fog_escalation_kpa=0.3, mist_max_closed_vent_s=600) vs Monday (clear+windy, fog_escalation_kpa=0.3, mist_max_closed_vent_s=900) on vpd_high_stress hours. Monday has higher wind (20-29 mph) but similar outdoor VPD. If 900s sealed-vent on Monday yields fewer vpd_high stress hours per unit outdoor VPD than Saturday’s 600s, extended sealed-vent is the dominant lever even in windy conditions. Expected outcome: Monday’s vpd_high_stress_hours / avg_outdoor_vpd ratio should be lower than Saturday’s ratio, demonstrating that 900s sealed-vent compensates for wind-driven infiltration losses better than 600s. | target_score=45 | target_compliance=40% | expected_stress=[heat=3.0, cold=0.5, vpd_high=12.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: By maintaining mister_engage_kpa=1.3 and bias_cool=+4 at ALL times (including overnight), we prevent the two dominant failure modes: (1) mister engage threshold above the tight nighttime vpd_high band ceiling, and (2) vent oscillation during heating. During daytime peak stress, aggressive misting (gap=20s, weight=2.5-3.0) with extended sealed-vent periods (900s) will maximize evaporative cooling. This should dramatically reduce the 41.1h vpd_high stress seen on April 10. Result: [backfill] compliance unavailable over plan window 2026-04-11 10:27 → 2026-04-11 11:12 Score: 4/10

Hypothesis

Conditions: Three challenging days ahead: Saturday (today) overcast with 76°F high and 17% low RH, Sunday extremely dry (7% RH, 76°F, clear afternoon), Monday windy (20-29 mph) with 70°F and 11% RH clearing to sun midday. Tuesday brings a cold front (46°F high, 33% RH) — much easier. Current state is SEALED_MIST_S1 at 4:25 AM with indoor temps 61-68°F and VPD 0.82-1.16 kPa. Today’s partial scorecard shows 0% compliance and 20.6h vpd_high stress — the active plan’s daytime settings are struggling against dry conditions despite overcast skies. Lettuce and strawberry seedlings in east zone show stress (wilting, yellowing, browning) likely from temperature/light issues outside this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, mist_max_closed_vent_s=900, pulse_gap=15s at peak) vs Saturday (fog_escalation_kpa=0.3, mist_max_closed_vent_s=600, pulse_gap=20s at peak) on vpd_high stress hours normalized by outdoor VPD. Sunday is ~2.5x drier. If fog_escalation 0.2 + 900s sealed-vent compensates, Sunday’s vpd_high_stress / avg_outdoor_VPD ratio should be ≤ Saturday’s ratio. Expected outcome: Sunday vpd_high_stress_h / avg_outdoor_VPD ≤ Saturday’s ratio, demonstrating that tighter fog escalation (0.2 vs 0.3) is the dominant lever for extreme dryness beyond sealed-vent extension alone. | target_score=55 | target_compliance=55% | expected_stress=[heat=2.0, cold=0.5, vpd_high=7.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: Maintaining mister_engage_kpa=1.3 at ALL transitions (including overnight), bias_cool=+3 to +4 during all heating periods, and aggressive daytime misting posture (gap 20s, weight 3.0) on the extreme dry days will reduce vpd_high_stress from 41h to under 8h while keeping cold_stress under 1h by preventing vent oscillation during heating. Result: [backfill] compliance unavailable over plan window 2026-04-11 11:12 → 2026-04-11 12:02 Score: 4/10

Hypothesis

Conditions: Today (Sat) peaks 75°F with 17% RH and 100% cloud cover — moderate VPD stress expected. Sunday is the hardest day: 76°F peak with 7% RH, extreme dryness requiring maximum humidity retention. Monday peaks 70°F with 11% RH and high winds (20-29 mph), moderate difficulty. Tuesday brings a cold front (46°F high, 33% RH) — easy day, heater-dominant. Current scorecard shows 21.6h vpd_high stress today already, indicating the active plan’s morning posture was too passive before tree shade cleared. East zone lettuce/strawberry seedlings show stress (wilting, yellowing) — likely nutrient/light issues outside this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, mist_max_closed_vent_s=900, pulse_gap=15s at peak, mister_vpd_weight=3.0) vs Monday (fog_escalation_kpa=0.3, mist_max_closed_vent_s=900, pulse_gap=20s at peak, mister_vpd_weight=2.5) on vpd_high stress hours normalized by outdoor VPD. Sunday is ~2x drier but calmer winds. If fog_escalation 0.2 compensates for extreme dryness, Sunday’s vpd_high_stress / avg_outdoor_VPD should be ≤ Monday’s ratio. Expected outcome: Sunday vpd_high_stress / avg_outdoor_VPD ≤ Monday’s ratio, demonstrating that fog_escalation 0.2 + 3.0 weight effectively compensates for extreme dryness better than 0.3 + 2.5 weight on a windy moderate-dry day. | target_score=55 | target_compliance=55% | expected_stress=[heat=1.5, cold=0.0, vpd_high=7.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: Maintaining mister_engage_kpa=1.3 at ALL transitions (including overnight) with bias_cool=+3 during heating periods will eliminate the nighttime vpd_high stress that dominated April 10. Aggressive daytime misting (gap 20s, weight 3.0, max_closed_vent 900s) on Sunday/Monday will limit peak VPD stress despite extreme dryness. Saturday’s overcast conditions should allow moderate compliance. Result: [backfill] compliance unavailable over plan window 2026-04-11 12:02 → 2026-04-11 12:07 Score: 4/10

Hypothesis

Conditions: Today (Sat) is transitioning from overcast/cold morning (39°F) to warm dry afternoon (75°F, 16% RH) — extreme VPD stress expected 11AM-5PM. Today’s partial scorecard already shows 22.87h vpd_high stress, indicating the current plan’s daytime posture is insufficient. Sunday is the most extreme day: 76°F with 7% RH outdoor, producing outdoor VPD near 2.8 kPa — maximum misting aggression needed. Monday similar but slightly cooler (72°F, 9% RH). Tuesday brings a cold front (45°F high, 38% RH) — mild day, heating overnight. East zone seedlings (lettuce, strawberry, pepper) show stress from temperature/light issues outside this planner’s control surface. Vanda orchids and Canna lilies healthy. Testing: Compare Saturday afternoon (fog_escalation_kpa=0.3, mist_max_closed_vent_s=600, pulse_gap=20s) vs Sunday peak (fog_escalation_kpa=0.2, mist_max_closed_vent_s=900, pulse_gap=15s) on vpd_high stress hours per unit outdoor VPD. Sunday is ~2x drier. If the more aggressive Sunday posture compensates, Sunday’s vpd_high_stress/avg_outdoor_VPD ratio should be ≤ Saturday’s. Expected outcome: Sunday vpd_high_stress normalized by average outdoor VPD (expected ~2.5 kPa avg) should be ≤ Saturday’s ratio (expected ~2.0 kPa avg outdoor VPD). Specifically: Sunday vpd_high_h/2.5 ≤ Saturday vpd_high_h/2.0. | target_score=45 | target_compliance=40% | expected_stress=[heat=1.0, cold=0.5, vpd_high=10.0, vpd_low=0.5] | expected_cost=USD 7.0

Hypothesis

Conditions: Today (Sat) is transitioning from overcast morning to clearing by 18:00, with outdoor highs of 75°F and extreme dryness (16% RH). Current indoor conditions show VPD 0.88-1.09 kPa across zones with temps 61-67°F. Today’s partial scorecard shows 22.87h vpd_high stress — the active plan’s misting posture is insufficient for the dry conditions despite engage at 1.3. Sunday is the most extreme day: 76°F high with 7% RH outdoor, producing outdoor VPD up to 2.84 kPa. Monday similar but slightly cooler (72°F, 9% RH). Tuesday brings a cold front (45°F high, 38% RH) — much easier. East zone seedlings (lettuce, strawberry, pepper) show stress signs but these are likely light/nutrient issues outside tuning control. Canna lilies and Vandas healthy. Testing: Compare Sunday peak (fog_escalation_kpa=0.2, pulse_gap=15s, mist_max_closed_vent_s=900s) vs Monday peak (fog_escalation_kpa=0.3, pulse_gap=20s, mist_max_closed_vent_s=900s) on vpd_high stress hours. Sunday is drier (7% vs 9% RH) but has more aggressive misting. If the extra aggression compensates, Sunday’s vpd_high_stress per unit outdoor VPD should be ≤ Monday’s. Expected outcome: Sunday vpd_high_stress / avg_outdoor_VPD ≤ Monday’s ratio, demonstrating that fog_escalation 0.2 + gap 15s provides meaningful additional VPD control vs 0.3 + gap 20s on extreme dry days. | target_score=52 | target_compliance=50% | expected_stress=[heat=1.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 7.0

Validating previous cycle: iris-20260411-0045

Previous hypothesis: Maintaining mister_engage_kpa at 1.3 with aggressive sealed-vent misting (900s max closed on peak days) and fog escalation at 0.2 kPa on Sunday will reduce VPD_high stress hours. Nighttime bias_cool of +3-4°F prevents vent oscillation during heating. On Sunday’s extreme dryness, extending mist_max_closed_vent_s to 900s with mister_pulse_gap_s of 15s during peak stress will maximize humidity retention. Result: [backfill] compliance unavailable over plan window 2026-04-11 12:47 → 2026-04-11 13:32 Score: 4/10

Hypothesis

Conditions: Today (Sat) is overcast with clearing at 18:00, high 75°F, low RH 16% — moderate VPD stress expected during afternoon. Sunday is the hardest day: clear to partly cloudy, 76°F high, extreme dryness (7% RH), 13h forecast stress. Monday similar but slightly cooler (72°F) with 9% RH. Tuesday brings a cold front (45°F high, 38% RH) — much easier VPD but cold overnight (41°F). Current scorecard shows 0% compliance today with 23.87h vpd_high and 11.5h cold stress — the active plan’s morning settings haven’t engaged yet (tree shade transition at 09:59). East zone seedlings (lettuce, strawberry, pepper) show stress from low temps/light — informational only, outside tuning surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, pulse_gap=15s, mist_max_closed_vent_s=900s) vs Monday (fog_escalation_kpa=0.3, pulse_gap=20s, mist_max_closed_vent_s=900s) on vpd_high stress hours normalized by average outdoor VPD. Sunday is drier (7% vs 9% RH) but has more aggressive fog/misting. If the extra aggression compensates, Sunday’s vpd_high_stress per unit outdoor VPD should be ≤ Monday’s. Expected outcome: Sunday vpd_high_stress_h / avg_outdoor_vpd ≤ Monday vpd_high_stress_h / avg_outdoor_vpd, demonstrating that fog_escalation 0.2 + gap 15s compensates for the extra dryness vs 0.3 + gap 20s. | target_score=55 | target_compliance=55% | expected_stress=[heat=1.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: Maintaining bias_cool +3 on cold nights prevents vent oscillation (validated). For daytime dry stress, using fog_escalation_kpa=0.3 with mist_max_closed_vent_s=900 on the two extreme days (Sun/Mon) and 600 on the moderate day (Sat) will keep VPD_high stress under 4h/day. Shortening vpd_watch_dwell_s to 30s during peak stress windows will catch VPD spikes faster.

Hypothesis

Conditions: Today (Sat) is overcast with outdoor high 76°F and very low RH (16-26%), creating significant VPD stress potential. Current indoor temps 63-67°F with VPD 0.80-0.93 kPa — within band but approaching ceiling. Today’s partial scorecard shows 24.4h cold_stress and 7.4h vpd_high_stress, indicating overnight vent oscillation and daytime dryness issues from the prior plan’s early transitions. Sunday is the most extreme day: 76°F high with 7% RH outdoor, producing massive VPD pressure. Monday similar but slightly cooler (72°F, 9% RH). Tuesday brings a cold front (45°F high, 38% RH) — much easier conditions. East zone seedlings (lettuce, strawberry, pepper) show stress from cold/light issues — not addressable via this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, pulse_gap=15s, mist_max_closed_vent_s=900s) vs Monday (fog_escalation_kpa=0.3, pulse_gap=20s, mist_max_closed_vent_s=900s) on vpd_high stress hours normalized by average outdoor VPD. Sunday is drier (7% vs 9% RH) but has more aggressive fog/misting settings. Expected outcome: If fog_escalation 0.2 with 15s gap compensates for extreme dryness, Sunday’s vpd_high_stress_hours / avg_outdoor_VPD ratio should be ≤ Monday’s ratio despite Sunday being ~30% drier. This tests whether the extra fog aggression is proportional to the dryness increase. | target_score=55 | target_compliance=55% | expected_stress=[heat=1.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 6.5

Previous hypothesis: Lowering vpd_watch_dwell_s to 30s during peak stress periods, extending mist_max_closed_vent_s to 900s on the driest days (Sun/Mon), using fog_escalation_kpa=0.2 on Sunday (extreme dry), and maintaining aggressive mister_pulse_gap_s=15-20s during peak hours will reduce vpd_high_stress hours compared to the current plan’s posture which is accumulating excessive VPD stress.

Hypothesis

Conditions: Today (Sat) is partially cloudy with outdoor high 76°F and extremely low RH (16-26%). Current indoor temps 64-67°F, VPD 0.93-1.06 kPa — within band but approaching VPD ceiling. Today’s partial scorecard shows severe cold_stress (26.8h) and vpd_high_stress (7.9h) indicating the previous plan’s daytime settings haven’t been active long enough or overnight was problematic. Sunday is the most extreme day: 76°F high with 7% RH outdoor — unprecedented dryness requiring maximum humidity retention. Monday similar (72°F, 9% RH). Tuesday brings a cold front (50°F high, 35% RH) — much easier. East zone seedlings (lettuce, strawberry, pepper) show stress from cold/light issues but these are outside this planner’s control surface. Testing: Compare Sunday (fog_escalation_kpa=0.2, pulse_gap=15s, mist_max_closed_vent_s=900s) vs Monday (fog_escalation_kpa=0.3, pulse_gap=20s, mist_max_closed_vent_s=900s) on vpd_high stress hours normalized by average outdoor VPD. Sunday is drier (7% vs 9% RH) but has more aggressive fog/misting settings. If fog_escalation 0.2 with gap 15s compensates for the extra dryness, Sunday’s vpd_high_stress/outdoor_VPD ratio should be equal to or lower than Monday’s. Expected outcome: Sunday vpd_high_stress_h / avg_outdoor_VPD ≤ Monday vpd_high_stress_h / avg_outdoor_VPD, demonstrating that 0.2 fog escalation + 15s gap adequately compensates for 7% vs 9% outdoor RH. | target_score=60 | target_compliance=65% | expected_stress=[heat=1.0, cold=0.5, vpd_high=8.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: Maintaining bias_cool +3 and bias_heat +1 on cold nights prevents vent oscillation (validated). For daytime dry periods, lowering fog_escalation_kpa to 0.2 on Sunday (extreme dryness) vs 0.3 on Monday (windy but less dry) will test whether earlier fog engagement compensates for extreme outdoor dryness. Extending mist_max_closed_vent_s to 900s on both dry days maximizes humidity retention. Shortening vpd_watch_dwell_s to 30s on peak stress periods ensures faster misting response.

Hypothesis

Conditions: Today (Sat) is hot-dry with 77°F/13% RH peak, clearing to cold clear night (low 44°F). Sunday is the most extreme day: 77°F/6% RH — exceptionally dry with VPD stress expected 13h. Monday moderates to 72°F/9% RH with clouds clearing midday, then a cold front drops Tuesday to 54°F/30% RH (easy day). Current scorecard shows 29.4h cold_stress today — likely from overnight vent oscillation before the active plan’s bias_cool kicked in. East zone lettuce/strawberry showing stress (health 5-6) but this is likely light/nutrient, not tuning-addressable. Dew point margin healthy at 9.9°F, zero disease risk. Testing: Compare Sunday (fog_escalation_kpa=0.2, pulse_gap=15s, mist_max_closed_vent_s=900s) vs Monday (fog_escalation_kpa=0.3, pulse_gap=20s, mist_max_closed_vent_s=900s) on vpd_high stress hours normalized by average outdoor VPD. Sunday is drier (6% vs 9% RH) but has more aggressive fog/misting settings. If fog_escalation 0.2 with gap 15s compensates for the extra dryness, Sunday’s vpd_high_stress/outdoor_VPD ratio should be equal to or lower than Monday’s. Expected outcome: Sunday vpd_high_stress_h / avg_outdoor_VPD ≤ Monday’s ratio, demonstrating that 0.2 fog escalation + 15s gap compensates for 6% vs 9% RH difference. Expected Sunday vpd_high ~6-8h (physics-limited), Monday ~4-5h. | target_score=52 | target_compliance=50% | expected_stress=[heat=1.0, cold=0.5, vpd_high=7.0, vpd_low=0.5] | expected_cost=USD 7.0

Validating previous cycle: iris-20260411-0345

Previous hypothesis: Maintaining aggressive misting posture (engage 1.3, gap 20-25s) through the full daytime window on Sunday/Monday, combined with 900s sealed-vent time and fog_escalation_kpa=0.2 on Sunday (the driest day), will limit vpd_high_stress to <10h on Sunday despite 7% outdoor RH. On cold nights, bias_cool +3 and bias_heat +1 will prevent vent oscillation (validated lesson). Widening fog_escalation to 0.4 on the mild Tuesday night will prevent vpd_low overshoot.

Hypothesis

Conditions: Today (Sat) is warm-dry with outdoor highs 77°F and RH dropping to 13%, clearing to calm evening with lows near 50°F. Sunday is the most extreme day: 77°F high with 6-7% RH, clear morning transitioning to overcast by 14:00, extremely dry all day. Monday is slightly cooler (72°F high, 9-12% RH) with clouds clearing at 11:00 then returning. Tuesday is cold (54°F high, 30% RH) and wet — minimal stress expected. Today’s partial scorecard shows 30h cold_stress which is alarming — likely from overnight vent oscillation before the current plan’s bias_cool took effect. East zone seedlings (lettuce, strawberry, pepper) show stress indicators but these are likely light/nutrient issues outside tuning control. Testing: Compare Sunday evening-to-overnight transition: bias_cool +3 with min_heat_off_s 300 vs Monday evening with bias_cool +4 and min_heat_off_s 240. Monday night is colder (lows 47°F vs 50°F). If bias_cool +4 with shorter heat cycling prevents cold_stress on the colder night while bias_cool +3 handles the milder night, we establish the threshold where +4 is needed. Expected outcome: Sunday night (bias_cool +3, low ~50°F) should have 0h cold_stress. Monday night (bias_cool +4, low ~47°F) should also have 0h cold_stress. If Monday shows any cold_stress with +4, the heater capacity is the bottleneck at sub-47°F outdoor temps. Both nights should have <0.5h vpd_low_stress. | target_score=62 | target_compliance=70% | expected_stress=[heat=1.0, cold=0.5, vpd_high=5.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: Tightening fog_escalation_kpa to 0.2 on the two extreme dry days (Sun/Mon) combined with 900s sealed-vent and 15s pulse gaps during peak stress will reduce vpd_high stress hours below 6h/day despite outdoor RH of 7-11%. On Saturday (moderate), fog_escalation 0.3 with 600s sealed-vent should keep vpd_high under 4h. Cold nights get bias_cool +3 and bias_heat +1 per validated lesson.

Hypothesis

Conditions: Today (Sat) is clearing with outdoor RH 13-21% and highs ~76°F — moderate VPD stress expected through afternoon. Current scorecard shows 31.2h cold_stress and 6.1h vpd_low_stress today, indicating severe overnight vent oscillation issues that bias_cool must address. Sunday is the most extreme day: clear AM transitioning to overcast PM, outdoor RH dropping to 6-8% with highs 77°F — peak VPD stress day requiring maximum misting aggression. Monday is slightly cooler (72°F high) with clouds arriving at 11:00, easing VPD pressure. Tuesday is cool (56°F high, 28% RH) with minimal stress expected. East zone seedlings (lettuce, strawberry, pepper) show stress from cold/light issues — maintaining warmer overnight temps via bias_heat will help. Overnight lows: Sat 48°F, Sun 55°F, Mon 45°F, Tue 41°F — all nights need heating with bias_cool protection against vent oscillation. Testing: Compare Sunday peak (13:00-18:00, outdoor RH 6-8%, mist_max_closed_vent_s=900, fog_escalation_kpa=0.2, gap=15s) vs Monday peak (11:00-15:00, outdoor RH 9-12%, mist_max_closed_vent_s=900, fog_escalation_kpa=0.3, gap=20s). Sunday is ~40% drier. If the more aggressive Sunday posture (0.2 fog escalation, 15s gap) keeps VPD_high stress per unit outdoor VPD comparable to Monday’s milder posture, it validates scaling fog_escalation inversely with outdoor RH. Expected outcome: Sunday VPD_high stress hours / avg outdoor VPD should be within 20% of Monday’s ratio, demonstrating that fog_escalation_kpa 0.2 + gap 15s adequately compensates for extreme dryness. If Sunday’s ratio is >50% worse, fog_escalation 0.2 is insufficient for sub-10% RH conditions. | target_score=62 | target_compliance=70% | expected_stress=[heat=1.0, cold=1.0, vpd_high=5.0, vpd_low=1.0] | expected_cost=USD 7.5

Previous hypothesis: Lowering fog_escalation_kpa to 0.2 on Sunday (extreme dry, 7% RH) combined with 900s sealed-vent and 15s pulse gap at peak will keep vpd_high stress below 6h despite 2.5x drier conditions than Saturday. On Saturday, fog_escalation 0.3 with 600s sealed-vent should limit vpd_high to ~4h. Monday’s high winds will reduce vent effectiveness — extending sealed-vent to 900s and using fog_escalation 0.3 compensates.

Hypothesis

Conditions: Today (Sat) is partly cloudy with outdoor high 77°F and very dry air (15-27% RH), transitioning to a brutally dry Sunday (6-8% RH, 77°F, clear until 14:00 cloud shift) — the driest day in the horizon. Monday is moderately dry (9-28% RH, 72°F high) with clouds clearing at 11:00. Tuesday is the coolest day (58°F high, 27-48% RH) with precipitation chances rising to 39%. Today’s partial scorecard shows 31h cold_stress and 6h vpd_low_stress — likely from overnight band mismatch or ESP32 reboot corruption earlier today, not from the active plan’s tuning. East zone seedlings (lettuce, strawberry, pepper) show stress indicators but these are likely light/nutrient issues outside this planner’s control surface. Testing: Compare Sunday peak (13:00-18:00, outdoor RH 6-8%, fog_escalation_kpa=0.2, gap=15s, mist_max_closed_vent_s=900) vs Monday peak (11:00-15:00, outdoor RH 9-12%, fog_escalation_kpa=0.3, gap=20s, mist_max_closed_vent_s=900). Sunday is ~40% drier. If Sunday’s VPD_high stress hours per unit outdoor VPD is comparable to or lower than Monday’s ratio, it validates scaling fog_escalation inversely with outdoor RH on extreme dry days. Expected outcome: Sunday VPD_high_stress / avg_outdoor_VPD ≤ Monday’s ratio, demonstrating that 0.2 fog escalation + 15s gap compensates for extreme dryness.

Hypothesis

Conditions: Today (Sat) is partly cloudy with outdoor RH 15-27%, high 77°F — moderate dry stress remaining. Sunday is the most extreme day: clear morning transitioning to clouds at 14:00, outdoor RH drops to 6-8% with highs of 77°F — extreme VPD stress expected. Monday is similar but slightly cooler (72°F high) with clouds from 11:00 and outdoor RH 9-12%. Tuesday is mild (59°F high, 26-48% RH) — easy day. Today’s partial scorecard shows 31h cold_stress dominating, likely from overnight vent oscillation before the current plan’s bias_cool took effect. Crop health is generally good; lettuce seedlings show some stress (wilting/yellowing) possibly from cold overnight temps in east zone. Testing: Compare Sunday peak (13:00-18:00, outdoor RH 6-8%, fog_escalation_kpa=0.2, gap=15s, mist_max_closed_vent_s=900) vs Monday peak (11:00-15:00, outdoor RH 9-12%, fog_escalation_kpa=0.3, gap=20s, mist_max_closed_vent_s=900). If Sunday’s VPD_high stress hours per unit outdoor VPD is comparable to or lower than Monday’s ratio, it validates scaling fog_escalation inversely with outdoor RH on extreme dry days. Expected outcome: Sunday VPD_high_stress_h / avg_outdoor_VPD ≤ Monday’s ratio. Sunday target: <4h VPD_high stress despite 6% RH. Monday target: <3h VPD_high stress with 9-12% RH. Both nights should have 0h cold_stress with bias_cool +3. | target_score=55 | target_compliance=55% | expected_stress=[heat=1.0, cold=0.5, vpd_high=6.0, vpd_low=1.0] | expected_cost=USD 7.0

Previous hypothesis: Reducing mister_pulse_gap_s to 15s during peak stress on Sunday/Monday (the driest hours), combined with mist_max_closed_vent_s=900s and fog_escalation_kpa=0.2, will keep VPD_high stress under 6h/day despite 7-9% outdoor RH. On cold nights (Sun-Tue), bias_cool=+3 with bias_heat=+1 will prevent vent oscillation. Tuesday’s mild conditions should achieve near-zero stress.

Hypothesis

Conditions: Today (Sat) is overcast with outdoor 76°F/17% RH, clearing tonight to cold clear night (low 44°F). Sunday is the most extreme day: clear skies, 77°F high, outdoor RH dropping to 6-8% — the driest conditions in the horizon. Monday is cooler (70°F high) with clouds building by 10:00, still dry (11-15% RH). Tuesday is mild and cloudy (62°F, 25% RH) with rain chances. Today’s partial scorecard shows 31h cold_stress dominating — likely from overnight vent oscillation before the current plan’s bias_cool took effect. Crop health is generally good; lettuce seedlings show some stress (wilting/yellowing) possibly from cold or light, not actionable via this planner. Testing: Compare Sunday peak (13:00-19:00, outdoor RH 6-8%, fog_escalation_kpa=0.2, gap=15s, mist_max_closed_vent_s=900) vs Monday peak (10:00-17:00, outdoor RH 11-15%, fog_escalation_kpa=0.3, gap=20s, mist_max_closed_vent_s=900). Normalize VPD_high stress hours by average outdoor VPD for each period. If Sunday’s ratio is comparable to or lower than Monday’s, it validates that scaling fog_escalation inversely with outdoor RH compensates for extreme dryness. Expected outcome: Sunday VPD_high_stress_h / avg_outdoor_VPD should be ≤ Monday’s ratio, demonstrating fog_escalation 0.2 at 6% RH performs as well as 0.3 at 13% RH. Sunday total stress target <6h, Monday <3h, Tuesday <1h. | target_score=60 | target_compliance=65% | expected_stress=[heat=1.0, cold=0.5, vpd_high=5.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: Maintaining aggressive misting (engage 1.3, gap 20s, weight 2.5-3.0) with 900s sealed-vent on the extreme dry days (Sun/Mon) and fog_escalation 0.2 on Sunday (7% RH) vs 0.3 on Monday (9% RH) will keep VPD_high stress under 8h/day despite outdoor VPD >2.5 kPa. Cold nights get bias_cool +3 and bias_heat +1 to prevent vent oscillation. Tuesday’s mild conditions allow relaxed defaults. Result: [backfill] avg compliance 17.6% (stress 3.5 h) over plan window 2026-04-11 19:02 → 2026-04-12 12:31 Score: 2/10

Hypothesis

Conditions: Today (Sat) is clearing with outdoor 75°F/21% RH, indoor temps 77-79°F with highly variable zone VPD (south 0.52, north 2.01). Today’s partial scorecard shows severe cold_stress (31.2h) dominating — likely overnight vent oscillation before the current plan’s bias_cool took effect. Sunday is the most extreme day: clear skies, outdoor RH dropping to 6-8%, high 77°F — 13h forecast stress. Monday moderates (high 70°F, RH 11-17%, clouds clearing midday). Tuesday is mild (high 63°F, RH 23%, overcast). Crop health is generally good; lettuce seedlings show some stress (wilting/yellowing) possibly from cold overnight exposure. Testing: Compare Sunday peak (10:00-19:26, outdoor RH 6-8%, fog_escalation_kpa=0.2, gap=15s, mist_max_closed_vent_s=900) vs Monday peak (09:59-19:27, outdoor RH 11-17%, fog_escalation_kpa=0.3, gap=20s, mist_max_closed_vent_s=900). Normalize VPD_high stress hours by average outdoor VPD for each period. If Sunday’s normalized ratio is ≤ Monday’s, it validates that scaling fog_escalation inversely with outdoor RH compensates for extreme dryness. Expected outcome: Sunday VPD_high_stress_h / avg_outdoor_VPD ≤ Monday’s ratio, demonstrating fog_escalation 0.2 compensates for 2x drier conditions vs fog_escalation 0.3. | target_score=62 | target_compliance=70% | expected_stress=[heat=1.0, cold=0.5, vpd_high=5.0, vpd_low=0.5] | expected_cost=USD 7.0

Previous hypothesis: Maintaining bias_cool +3 on cold nights prevents vent oscillation cold_stress. During extreme dry daytime (Sun/Mon), aggressive sealed-vent misting (engage 1.3, gap 15-20s, max_closed 900s) with fog_escalation 0.2 kPa will minimize vpd_high stress. On moderate days (Sat with 16-26% RH), fog_escalation 0.3 kPa balances humidity without vpd_low overshoot. Tuesday’s mild conditions allow relaxed defaults. Result: [dominant: vpd_high_stress] Score 27.5, compliance 17.6% (temp 85.4%, VPD 23.1%). 17.25h vpd_high, 2.52h cold, 0.98h heat, 1.17h vpd_low. Cost USD 4.97. 8 ESP32 reboots during 9-11 AM disrupted morning VPD ramp control. Tight nighttime VPD band (0.3-0.6) vs natural 0.8-0.95 drift produced ~10-12h structural non-compliance. 36 gal misting water (below average) suggests insufficient daytime aggression. Score: 3/10

New finding: ESP32 reboot instability during morning peak (8 reboots in 2h) eliminates planning benefits for that window. When reboots are frequent, plan defensively — assume control will be interrupted and set wider bands/more conservative settings that degrade gracefully. Also: tight nighttime VPD bands (0.3-0.6 kPa) structurally cap compliance at ~55-60% regardless of daytime performance. Scoring methodology should eventually account for controllability windows. → Added to Lessons Learned

Hypothesis

Conditions: Sat afternoon SUNRISE. Current: 80.7F avg, north VPD 2.22, south 0.83. Outdoor 76.9F/20.7% RH. Yesterday: score 87, 97.1% compliance, 0.7h stress, USD 7.99. Sunday extreme dry (6-8% RH, 77F), Monday moderate dry (11-17% RH, 68F), Tuesday cooling with precip (43-63F, 23-53% RH). Testing: Compare Sunday peak (10-16, hysteresis 0.4, fog 0.2, gap 15s) vs Monday peak (10-14, hysteresis 0.3, fog 0.3, gap 20s). Normalize VPD_high stress by avg outdoor VPD. Expected outcome: Sunday normalized VPD_high ratio ⇐ Monday despite 2x drier. Target score 55, compliance 55%, expected cost ~USD 6.50.

Previous hypothesis: Sunday extreme dry: fog_escalation 0.2, gap 15s, sealed-vent 900s, engage 1.3, vpd_hysteresis 0.4 at peak keeps VPD_high under 6h. Wider hysteresis reduces VPD sawtooth. Monday moderate treatment as control. Tuesday conservative. Result: Governed overnight 4/11 8PM → 4/12 6:27AM. Today’s partial scorecard: score 58.3, compliance 62.9% (overnight easier conditions). Overnight VPD dipped to 0.38 kPa at times — below vpd_low 0.4, contributing ~1.2h vpd_low stress. Both heaters running at dawn (heat1 since 5:29, heat2 since 6:24) as expected for 46°F outdoor. bias_cool +3 / bias_heat +1 prevented cold_stress oscillation overnight — only 1.1h cold stress vs 0h with similar settings previously. Heat stress of 4.07h surprising for overnight — likely from slab thermal retention keeping temps above tight nighttime temp_high band. Hypothesis partially validated: overnight posture was reasonable but structural nighttime band tightness continues to limit compliance. The 2006 plan’s fog_escalation 0.2 setting didn’t apply overnight (fog blocked outside 07:00-17:00 window). Score: 5/10

New finding: Overnight heat stress (4h) on nights where outdoor drops to 46°F but indoor stays 62-63°F indicates the nighttime temp_high band (~62-65°F from crop profiles) is too tight for the slab’s thermal retention. The slab stores enough heat to keep greenhouse 7-10°F above outdoor regardless of bias settings. This is structural non-compliance that bias_cool cannot fix — it requires either crop band adjustment or acceptance as baseline. → Added to Lessons Learned

Hypothesis

Testing: Compare Sunday fog_escalation 0.2 at 7% outdoor RH vs Monday fog_escalation 0.2 at 13-18% outdoor RH. If Sunday produces any vpd_low_stress despite 7% outdoor RH, fog_escalation 0.2 is too aggressive even for extreme dry — should raise floor to 0.3. Expected outcome: Sunday: compliance 25-35% (structural overnight cap + extreme daytime), vpd_high 10-14h, cost USD 5-7. Monday: compliance 35-45% (less extreme, cloud cover), vpd_high 6-10h, cost USD 4-6. Zero vpd_low_stress on Sunday validates fog 0.2 for extreme conditions. | target_score=35 | target_compliance=30% | expected_stress=[heat=1.0, cold=1.0, vpd_high=12.0, vpd_low=0.5] | expected_cost=USD 6.0
