How to Fruit:

1. Cut or remove the top of the bag for vertical fruiting

2. Mist lightly or maintain ambient humidity

3. Allow fruits to grow tall before harvesting

Fruiting Conditions:

• Temperature: 16–22°C (61–72°F)

• Humidity: 85–90% RH

• CO₂:

  • <800 ppm = short stems, large caps

  • 1000–2000 ppm = tall, thick stems

• Light: 1000–1500 lux, 12 hrs/day

• Air Exchange: 5–6x/day minimum

Tips for Best Results:

• Cold shock might be necessary if pinning is lagging 

• To encourage thick stems, reduce air exchange during early growth, then increase later for cap development

• Avoid direct misting — surface water can deform fruits

• Harvest when caps just begin to widen for best texture
