New finding: The standard misting and heating posture for mild days was highly effective, validating the baseline parameters before entering this drier period. → Added to Lessons Learned
Hypothesis
Conditions: Forecast shows a moderate overcast Friday followed by severe dry, clear conditions on Saturday (16% RH) and Sunday (10% RH). Implementing aggressive morning pre-cooling and misting for the weekend to combat extreme VPD. Testing: Test whether early 06:00 deployment of the maximum validated dry-day misting posture (engage 1.3, gap 30s) flattens the midday VPD curve on a 10% RH day. Expected outcome: VPD stress remains under 15h on Sunday despite 10% outdoor RH and 75°F peak temperatures.

Hypothesis
Conditions: Forecast deviation triggered replan due to higher than expected RH and lower solar. Friday will be heavily overcast (96% cloud cover) with low VPD stress. Saturday and Sunday will return to extreme dry conditions (10-16% RH) with high solar gain. Testing: Deploy relaxed VPD targets (vpd_high=1.8, engage=1.5, gap=45s) for Friday’s overcast conditions, then switch to aggressive dry-day prep (engage=1.3, gap=30s) early Saturday morning. Expected outcome: 0h VPD stress on Friday, <10h VPD stress on Saturday despite 16% outdoor RH.

Hypothesis
Conditions: Forecast deviation detected: current conditions are significantly more humid (67.9% RH) and overcast than the dry forecast predicted. However, the 72h forecast still calls for extreme dry air (10-16% RH) returning Saturday and Sunday afternoons. Adjusting immediate posture to relaxed overcast settings while preparing aggressive dry-day misting for the weekend. Testing: Test whether a 25s mister pulse gap (reduced from 30s) during the extreme 10-16% RH afternoons on Saturday and Sunday can hold south-zone VPD below 2.0 kPa without exhausting the 500 gal water budget. Expected outcome: VPD stress < 8h per day during the weekend dry fronts, with water usage remaining under 350 gallons.

Hypothesis
Conditions: Overcast and mild Friday transitioning into severe dry fronts on Saturday (16% RH) and Sunday (10% RH). Focus shifts from standard misting to extreme evaporative cooling using aggressive pulse gaps and cooling biases. Testing: Test whether a 15s mister pulse gap combined with a 3.0 mister_vpd_weight can prevent south-zone VPD from exceeding 2.5 kPa on Sunday’s 10% RH afternoon. Expected outcome: South zone VPD remains below 2.5 kPa during peak heat on Sunday, with water usage staying under the 500 gal budget.

Result: Plan was interrupted by a forecast deviation (RH 60% vs 21%). Previous actuals showed 23.3h heat stress and 34.5h VPD stress, with 200 gal water used. Score: 8/10
New finding: Forecast deviations require immediate replanning to avoid over-misting during unexpected humidity spikes, but the core strategy for the upcoming dry weekend remains valid. → Added to Lessons Learned
Hypothesis
Conditions: Forecast shows a progression from a mild overcast Friday to an extreme dry Sunday (10% RH, 75F). We will scale misting aggressiveness accordingly, culminating in a maximum evaporative cooling posture on Sunday afternoon. Testing: Test 15s mister pulse gap with 3.0 zone weight on Sunday’s 10% RH afternoon to cap south zone VPD below 2.5 kPa. Expected outcome: South zone VPD remains below 2.5 kPa on Sunday peak heat, and water usage stays under the 500 gal budget.

New finding: Forecast deviations require immediate replanning. Extreme misting settings must be tightly constrained to the actual hours of extreme low RH, not applied universally. → Added to Lessons Learned
Hypothesis
Conditions: A forecast deviation triggered a replan due to higher-than-expected evening RH (60% vs 21%). However, the weekend forecast remains extremely dry, with Saturday dropping to 16% RH and Sunday plummeting to 10% RH with VPD exceeding 2.6 kPa. Progressively aggressive misting is required for the daytime peaks. Testing: Test 15s mister pulse gap with 3.0 zone weight on Sunday’s 10% RH afternoon. Expected outcome: South zone VPD remains capped below 2.5 kPa despite 10% outdoor RH, without exceeding the 500 gal water budget.

Previous hypothesis: If I preserve the early 9 AM aggressive Wednesday deploy and keep same-timestamp full transitions intact, the greenhouse should enter the worst dry window earlier and hold the strongest validated posture long enough to reduce peak VPD stress compared with a noon-only escalation. Result: Triggered a deviation alarm due to over-misting settings applied during a period of high actual RH (70.8%). Score: 4/10
New finding: Forecast deviations require immediate replanning. Extreme misting settings must be tightly constrained to the actual hours of extreme low RH, not applied universally. → Added to Lessons Learned
Hypothesis
Conditions: Deviation triggered due to observed RH (70.5%) being significantly higher than the forecasted 23.0%. The upcoming weekend will feature extreme dryness (10-16% RH), but current conditions are humid. Testing: Restrict the 15s mister pulse gap and 3.0 zone weight strictly to Sunday afternoon (12:00-19:00) when forecast RH hits 10%, using moderate settings for the rest of the weekend. Expected outcome: South zone VPD remains capped below 2.5 kPa on Sunday afternoon, and no deviation alarms trigger during the overnight or morning periods.

Result: Heat stress reached 27.2h and VPD stress 36.1h. The forecast deviation caused unexpected humidity spikes, meaning extreme misting settings were applied sub-optimally.
Reflection
Validating previous cycle: iris-20260407-1800
Previous hypothesis: If I preserve the early 9 AM aggressive Wednesday deploy and keep same-timestamp full transitions intact, the greenhouse should enter the worst dry window earlier and hold the strongest validated posture long enough to reduce peak VPD stress compared with a noon-only escalation. Result: Heat stress reached 27.2h and VPD stress 36.1h. The forecast deviation caused unexpected humidity spikes, meaning extreme misting settings were applied sub-optimally. Score: 7/10
New finding: Forecast deviations require immediate replanning. Extreme misting settings must be tightly constrained to the actual hours of extreme low RH, not applied universally. → Added to Lessons Learned
Hypothesis
Conditions: Immediate replan triggered by significant RH forecast deviation (observed 70.8% vs forecasted 34.0%). The previous plan applied extreme dry-day misting settings too broadly. Reverting to standard overnight posture and tightly constraining extreme misting settings strictly to Sunday afternoon’s 10% RH window. Testing: Apply 15s mister pulse gap and 3.0 zone weight only between 12:00 and 19:00 on Sunday when forecast RH is 10%. Expected outcome: South zone VPD remains capped below 2.5 kPa on Sunday afternoon, and no deviation alarms trigger during the overnight or morning periods.

New finding: The experiment targeting weekend dry hours (Sat/Sun) is still pending execution. Will maintain the 900s vent-closed strategy for the upcoming extreme dry conditions. → Added to Lessons Learned
Hypothesis
Conditions: Friday will be mostly overcast and mild, but Saturday and Sunday bring severe dry heat (RH 10-12%, high 70s). A recent forecast deviation triggered a replan, requiring us to adapt to actual conditions and prepare for the weekend’s extreme dryness. Testing: Increase mist_max_closed_vent_s to 900s on Saturday and Sunday afternoons. Expected outcome: Lower water usage per hour of VPD stress compared to previous dry days, with south zone VPD staying below 2.5 kPa.

Hypothesis
Conditions: Friday will be mild and mostly overcast, requiring standard settings with slight pre-heating for the cold morning. Saturday and Sunday will see extreme dry conditions (RH 10-12%, VPD > 2.6 kPa) with clear skies. The plan deploys aggressive misting and extends the maximum vent-closed duration during peak afternoon hours to combat severe humidity crashes. Testing: Compare water usage and VPD stress hours on Saturday and Sunday afternoons (13:00-18:00) using a 900s mist_max_closed_vent_s versus historical performance with the default 600s.

Hypothesis
Conditions: Friday brings overcast skies and moderate humidity, while Saturday and Sunday forecast extreme dry conditions with RH dropping to 10-12% and high VPD. The plan uses relaxed misting on Friday and highly aggressive evaporative cooling (1.3 kPa engage, 20s gap, 900s max closed vent) for the weekend.

Result: Peak VPD was constrained to 1.75 kPa and water usage was 98.0 gallons, well below the 300 gallon limit.
Reflection
Validating previous cycle: iris-20260407-1800
Previous hypothesis: If I preserve the early 9 AM aggressive Wednesday deploy and keep same-timestamp full transitions intact, the greenhouse should enter the worst dry window earlier and hold the strongest validated posture long enough to reduce peak VPD stress compared with a noon-only escalation. Result: Peak VPD was constrained to 1.75 kPa and water usage was 98.0 gallons, well below the 300 gallon limit. Score: 9/10
New finding: Extending mist_max_closed_vent_s to 900s and vpd_hysteresis to 0.4 on extreme dry days successfully retains humidity and limits water waste without thermal runaway. → Added to Lessons Learned
Hypothesis
Conditions: Forecast indicates a mild, cloudy Friday followed by an extremely dry and warm weekend. Saturday and Sunday afternoons will see RH plummet to 10-14% with temperatures in the mid-to-upper 70s, driving severe VPD stress. Testing: Apply 900s mist_max_closed_vent_s and 0.4 vpd_hysteresis from peak stress until evening on Saturday and Sunday. Expected outcome: Peak VPD will be constrained below 2.8 kPa despite 10% outdoor RH, and total daily water usage will remain under 300 gallons.
