Where the Magic Happens
Fruiting Chamber
Optimal fruiting conditions are key to abundant harvests. Learn to create the perfect environment for your mushrooms.
Where the Magic Happens
Your fruiting chamber is where colonized substrate transforms into beautiful mushroom harvests. The key factors are humidity, fresh air exchange (FAE), light, and temperature. Get these right, and you'll be rewarded with abundant flushes of premium mushrooms.

Environment Matters
Perfect Conditions
Small adjustments in humidity, airflow, and temperature can dramatically impact your yields.
The Four Keys to Fruiting
Humidity (85-95%)
Use a humidifier or mist regularly. Too dry = cracked caps. Too wet = contamination. Monitor with a hygrometer.
Fresh Air Exchange
Mushrooms exhale CO2 and need fresh oxygen. Fan or vent your chamber multiple times daily.
Light (12hr cycle)
Indirect light triggers pinning and directs growth. A nearby window or simple LED works perfectly.
Temperature
Most species fruit at 55-75°F. Cooler temps often produce denser, higher-quality mushrooms.
