Cultivation
Fruiting chamber
The room where the work pays off. Humidity, fresh-air exchange, and light, in the proportions we run on the farm.
A fruiting chamber is the controlled environment where colonized substrate shifts from vegetative growth to producing mushrooms. Three variables dominate the room: relative humidity, fresh-air exchange (FAE), and light. Get those right and most species behave; get them wrong and even an aggressive strain pins poorly.
What we run on our farm
- ▸Active humidification with cool mist, never hot fog. Targeting 85-95% relative humidity depending on species and stage.
- ▸Active FAE with HEPA-filtered intake and timed exhaust. Most species pin between 800 and 1,200 ppm CO₂; primordia form in lower CO₂ than they need during pinning.
- ▸Indirect ambient light. Mushrooms do not photosynthesize but most species need a light cue to know which way is up.
- ▸Surfaces designed to be wiped down between flushes. Wood is the enemy.
