About this strain
A yellow reishi variety that grows as slender, finger-like growths of a bright golden-yellow colour. It is grown in a closed bag, opened only once the growths reach the top; after that it copes well with full light, even direct sun. The mushrooms are hard and woody — they are dried and used for infusions.
How to grow it
Preparation
- Substrate
- hardwood sawdust (fine and coarse) with approx. 10–15% bran, sterilised — more bran inhibits fruiting; outdoors: hardwood logs and stumps
- Spawn rate
- 1–2% on sterilised sawdust
Growing stages
Spawn run (incubation)
- Temperature
- 21–27°C
- Humidity
- 95–100%
- Duration
- 10–20 days
- CO₂
- tolerates up to approx. 50,000 ppm
- Fresh air
- 0–1 per hour
Primordia (“antlers”)
- Temperature
- 18–24°C
- Humidity
- 95–100%
- Duration
- 2–4 weeks
- CO₂
- 20,000–40,000 ppm
- Fresh air
- 0–1 per hour
- Light
- 200–500 lx, 4–8 h / 24 h
High CO₂ stretches the growths into “antlers”; the light source sets the direction of growth.
Growth of the fingers
- Temperature
- 15–25°C
- Humidity
- 85–95%
- Duration
- several weeks
- CO₂
- high — inside the closed bag
- Fresh air
- none until the bag is opened
- Light
- >1,000 lx, after opening the bag even direct sun
Open the bag once the growths reach the top.
Harvest
- Flushes
- 1 main
Harvest when the growths stop extending and their tips harden. Dry them; they are hard and woody and are not eaten fresh.
Please note: these growing parameters bring together the experience of practising growers — a starting point, not a guarantee of results. Every grow has its own substrate, climate and equipment, and even small differences can noticeably change the yield. Adjust these values to your own conditions.
