Bin 4

Sensor CH4. Galvanized stock tank on the south parapet wall / extra edible overflow bin. Current living plants: large parsley clump at the back/upper end, 3 alpine strawberries near the center/right edge, and a small group of scallions near the middle. Also contains one dead/failed ornamental grass clump at the lower/front end; do not use ornamental-only watering logic anymore. Mixed edible moisture target: moderate-moist, prioritizing parsley and strawberries while avoiding soggy soil. Water when CH4 drops below ~35%; treat 35–65% VWC as Good and 65%+ as Wet until the sensor is calibrated by touch.
