About this strain
A close relative of the jelly ear, grown on a large scale in Asia. It has thicker, meatier mushrooms with a velvety, hairy, grey-brown underside and an even crunchier texture. Mild in flavour, it is valued mainly for its texture — excellent in soups, salads and stir-fries. It shrinks when dried and regains its shape when soaked.
It likes higher temperatures than the jelly ear, so it crops well in summer and in warm rooms. It grows on sterilised hardwood sawdust with added bran and on logs.
How to grow it
Preparation
- Substrate
- blocks: hardwood sawdust (fine and coarse) with approx. 20% supplement, e.g. bran, sterilised; moisture approx. 60–65%; outdoors: hardwood logs

- Duration
- approx. 4–6 weeks
- CO₂
- >5,000 ppm
Primordia formation
- Temperature
- 23–30°C
- Humidity
- 85–95%
- CO₂
- <2,000 ppm

- Light
- 500–1,000 lx
Pinning is triggered by a night-time temperature drop at high humidity.
Fruiting
- Temperature
- 23–30°C
- Humidity
- 85–95%
- CO₂
- <2,000 ppm
- Fresh air
- high air exchange
- Light
- 500–1,000 lx

Pick when the edges of the mushrooms start to ruffle. Between flushes let the substrate dry slightly, then raise humidity again.
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.
