Record: Depth at five points, the daily damp check, every watering with quantity, the date mycelium reached the valleys.
On casing day measure the layer depth at five points on each bed and write them down.
Each day lift a pinch of casing from three places and record whether it is damp all through.
Record every watering with date, time and litres per square metre, not a guess.
From day 5, look into the casing valleys daily and record when white threads appear across the bed.
