Climate control is the heart of successful mushroom cultivation. Learn about the key parameters, sensor placement, and control strategies used in professional growing facilities.

The Science of Mushroom Climate Control

Maintaining optimal growing conditions is crucial for consistent, high-quality mushroom production. This article explores the key aspects of climate control in modern growing facilities.

Critical Parameters

1. Temperature

  • Spawn run: 24-26°C

  • Pinning initiation: Drop to 16-18°C

  • Cropping: 16-18°C

2. Relative Humidity

  • Spawn run: 95-98% RH

  • Pinning: 90-95% RH

  • Cropping: 85-90% RH

3. CO2 Levels

  • Spawn run: Up to 10,000 ppm acceptable

  • Pinning: Reduce to 1,000-1,500 ppm

  • Cropping: Maintain 800-1,200 ppm

Air Handling System Design

A well-designed air handling unit (AHU) should provide:

  • Sufficient fresh air intake for CO2 control

  • Precise temperature control (±0.5°C)

  • Uniform air distribution across all shelves

  • Humidity control through steam injection or atomization

Sensor Placement Strategy

Proper sensor placement ensures accurate readings:

  • Temperature sensors at multiple heights on each shelf tier

  • Humidity sensors in return air duct and growing room

  • CO2 sensors at mushroom canopy level

WOCODO's Smart Climate Controller integrates all these sensors into a unified system with automated adjustment capabilities.
