Result: Plan-window score 52.2 with 55.5% both-axis compliance, temp compliance 62.2%, VPD compliance 63.1%, about 2.58h heat stress and 2.58h VPD-high stress, no VPD-low, and plan-window cost about USD 4.11. Daily sunset score improved to 61.5 vs 49.9 7d average with 65.4% both-axis compliance, but the day still hit 5.08h heat and 5.08h VPD-high and used the full 600 gal mister budget with total cost USD 8.09. The structured hypothesis was directionally right: band-coupled moisture plus capped 180s sealed windows avoided VPD-low and dew risk (dp margin min 5.6F, 0 dp-risk hours), but heat and VPD-high remained physics-limited and water cost became the score penalty. Repeated evening moisture-guardrail clamps show the plan still unwound or requested conservative moisture before observed recovery was complete.

Reflection

Validating previous cycle: iris-20260514-2009

Previous hypothesis: SUNSET overnight plan for 2026-05-14. Today underperformed: score 47.6 vs 52.7 7d average, both-axis compliance 42.0%, temperature was the weaker axis at 47.2% vs 53.8% VPD, and the stress mix was severe heat plus VPD-high (10.43h heat, 9.13h VPD-high, 0h VPD-low). Cost stayed under the USD 5 target but worsened vs trend (USD 4.51 vs USD 3.27 7d), driven by 600 gal mister water and 5.97 kWh, not gas. I evaluated iris-20260514-0546 at 4/10 versus anchor 3: the plan avoided dew/VPD-low carryover, but peak heat and VPD-high remained worse than predicted and repeated guardrail clamps showed conservative moisture unwind was requested before observed VPD recovery. Tonight’s main challenge is dry-air recovery without creating dew risk: current dew margin is healthy (~15F) and outdoor air stays very dry, so I keep near-band recovery until late evening, then widen gaps/thresholds overnight, then pre-stage Friday’s severe 86F/7% RH/~915 W/m2 dry ramp before 09:00.

Result: Plan-window score 52.2 with 55.5% both-axis compliance, temp compliance 62.2%, VPD compliance 63.1%, about 2.58h heat stress and 2.58h VPD-high stress, no VPD-low, and plan-window cost about USD 4.11. Daily sunset score improved to 61.5 vs 49.9 7d average with 65.4% both-axis compliance, but the day still hit 5.08h heat and 5.08h VPD-high and used the full 600 gal mister budget with total cost USD 8.09.

Repeated evening moisture-guardrail clamps show the plan still unwound or requested conservative moisture before observed recovery was complete. Score: 6/10

New finding: On severe hot-dry days, band-coupled mist/fog with short sealed windows can improve both-axis compliance and avoid VPD-low, but if VPD-high/VENTILATE persists into sunset with healthy dew margin, keep a short evening recovery shoulder until observed VPD is safely below band; then unwind quickly overnight to control water cost. → Added to Lessons Learned

Hypothesis

Testing: Test whether holding guardrail-safe band-coupled moisture through the late cloudy-but-dry window, then unwinding only after expected observed recovery, reduces VPD-high without producing VPD-low or dew risk. Expected outcome: Expect today to remain structurally hard: target both-axis compliance 50-65%, VPD-high under 5h, VPD-low near 0h, dew margin above 5F, and no extension of sealed heat traps beyond 180s. Heat stress may still reach 5-7h if indoor load follows the 86F/900 W/m2 forecast.

Severe hot-dry day with clear morning, 862-910 W/m2 noon/early afternoon solar, RH 5-9% from 12:00-19:00, and late cloud cover that may reduce solar but not immediately fix dry outdoor air. Current indoor dawn is safe: 65F, VPD 0.63 kPa, dew margin about 10F, mode IDLE.

Expected stress windows

vpd_highhigh · 2026-05-15T08:30:00-06:00 to 2026-05-15T19:30:00-06:00

Use band-coupled physical mist thresholds near active vpd_high, 30-60s mist delays, 15-20s peak gaps, fog_escalation_kpa 0.15-0.20 in the 07:00-17:00 firmware window, and mister_vpd_weight 3.0 during the peak.

heathigh · 2026-05-15T11:30:00-06:00 to 2026-05-15T18:30:00-06:00

Pre-cool with bias_cool -1.5 to -2.0, d_cool_stage_2 2.0, summer vent gate on, dwell gate on, and mist_max_closed_vent_s capped at 180s so THERMAL_RELIEF can flush heat.

vpd_lowlow · 2026-05-15T20:30:00-06:00 to 2026-05-16T06:30:00-06:00

After the dry window, unwind to engage 1.35, all 1.80, 50s gaps, fog escalation 0.90 while fog is time-window blocked, and vpd_hysteresis 0.50; do not unwind before observed VPD recovery.

Parameter rationale

mister_engage_kpa1.4 → 0.88; RH 5-13%, VPD 2.55-4.01 kPa, solar 759-910 W/m2 from 11:00-15:00; recent guardrail clamps pulled requested 1.165 toward 0.930.

avoid waiting for dispatcher clamps and reduce VPD-high stress during VENTILATE.

mister_all_kpa1.85 → 1.05; active vpd_high about 0.84; guardrail recommends all-zone near vpd_high+0.25 during live or near-edge stress.

make all-zone escalation available during the severe dry peak without overusing it overnight.

mister_engage_delay_s120.0 → 30.0; VPD ramp begins around 08:00-09:00 and forecast VPD exceeds 2.5 kPa by 10:00.

prevent missed early VPD-high excursions.

mister_all_delay_s240.0 → 60.0; recent guardrail caps long all-zone delays to about 90s in active stress.

bring all-zone assist within one minute at peak.

mister_pulse_gap_s55.0 → 15.0; validated dry-day lessons recommend 15-25s gaps under RH <15% and solar >800 W/m2.

speed evaporative recovery while peak solar is active.

fog_escalation_kpa0.9 → 0.15; PR-A allows vent-fog assist near vpd_high_eff + escalation; today is hot/dry enough for fog to be the high-leverage VPD tool before 17:00.

use fog for stubborn VPD-high rather than extending sealed heat traps.

min_fog_off_s120.0 → 45.0; recent clamps pulled 115s requests toward 55s in VPD-high VENTILATE stress.

allow timely fog cycling during peak dry stress.

bias_cool4.0 → -2.0; forecast high 86F with 862-910 W/m2 solar and structural heat risk from late morning through evening.

start ventilation/fan cooling earlier and reduce avoidable heat stress.

d_cool_stage_23.0 → 2.0; physics-limited cooling day; fan2 should not wait far above the shifted cooling threshold.

bring full fan support earlier during the peak.

vpd_watch_dwell_s90.0 → 30.0; fast dry ramp and repeated guardrail clamps during near-edge stress.

enter bounded recovery sooner without disabling dwell gate.

mist_backoff_s900.0 → 600.0; short 180s sealed attempts may time out under heat, but repeated bounded recovery is useful.

permit recurring recovery cycles while avoiding long sealed heat traps.

mister_vpd_weight2.0 → 3.0; south/west mister paths are most productive and Vanda roots remain dry; zone spread is modest but stress risk is high.

prioritize the driest/high-value recovery zones during the peak.

vpd_hysteresis0.5 → 0.35; fast VPD ramp needs responsiveness; overnight restores 0.50 to avoid VPD-low.

reduce missed high-VPD entries during peak without narrowing the overnight posture.

mist_max_closed_vent_s180.0 → 180.0; validated lesson 89: do not extend sealed mist at high temperature and low outdoor RH.

avoid turning humidity recovery into a heat trap.

Result: Plan-window score was 99.0 with 98.8% both-axis compliance, 100.0% temp compliance, 98.8% VPD compliance, only 0.03h VPD-high stress, 0h heat/cold/VPD-low stress, and about USD 0.02 cost. The experiment succeeded: the short evening recovery shoulder plus hard overnight unwind avoided VPD-low and dew risk while sharply reducing overnight water/cost after the prior 600 gal dry-day budget hit. Current sunrise conditions remain safe (63F, VPD 0.36 kPa, RH 82%, dew margin 5.6F, IDLE), so the morning can start guarded rather than aggressively misting before live VPD rises.

Reflection

Validating previous cycle: iris-20260515-0546

Previous hypothesis: SUNRISE severe hot-dry plan for Friday 2026-05-15. Yesterday’s daytime score remained weak on both axes under physics-limited heat and VPD stress, but the overnight plan validated delayed moisture unwind: 92.8% plan-window compliance, no VPD-low, and safe dew margin. Today is another severe dry-air day: forecast peak 86F, minimum RH 5%, and solar near 910 W/m2 before late clouds. Because forecast VPD/RH tends to overstate dryness but recent clamps show the current plan is still too conservative during near-edge VPD stress, this plan starts with a measured dawn guard, moves to band-coupled mist/fog by the 08:30-09:00 ramp, holds aggressive support through the late hot/dry window instead of unwinding at the first cloud signal, then widens thresholds after observed evening recovery. Heat will remain structurally limited; I am not extending sealed-mist windows beyond 180s.

Hypothesis

Conditions: Sunset after severe hot-dry day: daily score 61.5, both-axis compliance 65.4%, heat and VPD-high each 5.08h, no VPD-low, dp_margin_min 5.6F. Current greenhouse is 67.8F, VPD 0.79 kPa, RH 67%, dew margin 11.4F, mode VENTILATE. Overnight remains dry outside but mild, then Saturday has another dry solar ramp to 82F, 13-14% RH and 835 W/m2 solar. | outdoor peak: 82.0, RH min: 13.0, solar peak: 835.0, cloud cover: 74.0 | stress windows: vpd_high 2026-05-15T20:15:00-06:00-2026-05-15T22:30:00-06:00 medium; vpd_low 2026-05-15T22:30:00-06:00-2026-05-16T03:00:00-06:00 low; vpd_high 2026-05-16T03:00:00-06:00-2026-05-16T08:30:00-06:00 medium; vpd_high 2026-05-16T08:30:00-06:00-2026-05-16T12:00:00-06:00 high Testing: Test a short recovery shoulder followed by a hard overnight unwind: can we keep overnight both-axis compliance high with 0h VPD-low/dp-risk while reducing water after the 600 gal dry-day budget hit? Expected outcome: Overnight plan-window both-axis compliance >85%, VPD-low 0h, dp-risk 0h, cold stress <0.5h, and substantially lower misting after 22:30; if SUNRISE misses, the 08:30 fallback should limit early VPD-high during Saturday’s dry ramp.

Parameter rationale

mister_engage_kpa1.0 → 1.45; Current VPD has recovered to 0.79 kPa near vpd_high 0.82 with dew margin 11.4F; lesson 105 warns to unwind overnight after aggressive dry-day support.

prevent VPD-low and reduce water after 22:30 while keeping short evening recovery available first.

mister_all_kpa1.2 → 1.85; No active VPD-high at sunset and fog is time-window blocked; all-zone escalation should not remain near daytime guardrail values overnight.

avoid expensive all-zone rotation overnight unless VPD rises materially.

mister_pulse_gap_s30.0 → 55.0; Night air holds humidity better and today's mister budget was fully spent at 600 gal.

cut overnight water use without increasing dew risk or VPD-low.

fog_escalation_kpa0.6 → 0.9; Fog is blocked after 17:00 and current VPD is recovered; high escalation prevents stale aggressive fog posture if a fallback persists.

avoid unnecessary fog/humidity overshoot overnight; lower again only for Saturday morning dry ramp.

min_fog_off_s90.0 → 120.0; Current dew margin safe but water/cost penalty is high and fog is unavailable overnight.

keep overnight fog conservative and avoid carryover if firmware window reopens before sunrise plan lands.

mister_engage_delay_s45.0 → 120.0; Overnight humidity recovery is already achieved; short delays are only needed during active VPD-high VENTILATE stress.

reduce false starts and water use in stable overnight air.

mister_all_delay_s90.0 → 240.0; All-zone rotation is costly and not needed while indoor VPD is near band.

reserve all-zone pulses for sustained VPD rise rather than transient dryness.

bias_cool0.5 → 3.5; Mild night still has heater potential against crop low band; validated lessons use +2 to +4 to prevent heater-to-vent oscillation.

avoid post-heating vent dumps and reduce cold stress/chatter.

bias_heat0.0 → 0.5; Outdoor forecast stays 58-63F, not a cold night; only modest warmth is needed to protect dew margin.

maintain dew margin without chasing expensive heating.

vpd_hysteresis0.4 → 0.5; VPD has recovered and the evening objective shifts from recovery to avoiding oscillation and VPD-low.

reduce short-cycle misting overnight.

vpd_watch_dwell_s45.0 → 75.0; No active high-VPD stress after recovery; short watch dwell is for confirmed dry ramp.

avoid reseal loops overnight, then return to 30s for morning fallback.

mist_backoff_s700.0 → 900.0; Sealed attempts should be less frequent overnight after costly daytime water use.

space recovery attempts and protect water budget.

mister_vpd_weight2.5 → 2.0; Zone spread is modest at sunset and peak-day driest-zone weighting is no longer necessary overnight.

reduce aggressive targeted water spend until live morning ramp.

d_cool_stage_22.5 → 2.0; Saturday forecast reaches 82F with RH 13-14% and solar up to 835 W/m2; fallback should not wait too long for fan2.

pre-stage full ventilation if sunrise cycle misses and dry ramp arrives.
