Compost Temperature

Compost Temperature helps the grower treat bed temperature as a biological signal and heat-removal obligation distinct from room-air temperature. The crop requirement is the starting question, not an equipment size.

The biological purpose is to keep the crop's stage, respiration, heat, gas exchange and surface-water behaviour visible.

Observe the crop, room pattern and change history before changing a control. Record what changed, where, when and under which operating mode.

Define the control volume, design case, load components, equipment boundaries, instrumentation and expected response. Biological requirement is not equipment size.

Look for spatial gradients, time trends, surface condition, crop response, door events, water events, equipment state and alarms rather than a single display value.

Retain sensor ID, unit, location, height or depth, timestamp, calibration state, crop stage, room load and operating mode with every measurement.

treat bed temperature as a biological signal and heat-removal obligation distinct from room-air temperature. Temperature, moisture, carbon dioxide, air movement, crop load and control actions can move together, oppose one another or hide a local problem.

Common errors include a non-representative sensor, an undefined design case, a fan rating treated as delivered airflow, an air-change rate treated as distribution, or a biological target treated as plant capacity.

Larger crop loads, longer air paths, more simultaneous equipment, tighter recovery needs and higher failure consequences increase the need for redundancy, commissioning and data history.
