Beside an indoor teaching mushroom bed, a rounded mecha gently cups one foam mushroom model just above its empty magnetic mount. An instructor gestures with a stop wristband on her raised right wrist. Three students remain behind the rail; one holds a harvest log card with both hands. The equipment table carries a separate gripper sample, divided liner, empty shallow basket, and short cleaning brush, with a breathable bag below. A humidity gauge sits on the bed post and a leaf-shaped label stand marks its nearer end. Other growing positions contain empty circular mounts and plants. Warm book-style colors and soft daylight make the model demonstration easy to observe; it does not establish real mushroom-harvesting performance.
