Record: Representative temperatures, visible development, dates and locations of abnormal or lagging bags, and associated material lots.
Number five bags spread across the room, including one near the door and one at the back.
Each morning read compost temperature at three depths in each marked bag.
Record visible development, abnormal areas and their location without opening or deliberately smelling bags.
On day 12 open one marked bag at the side and check whether white threads reach the bottom.
