About this strain

A snow-white shimeji variety that won the world over thanks to Japanese bottle farms. It forms compact clusters of small, smooth caps on firm stems; they are usually picked at about 2 cm across, before they open, although mature caps reach 7–9 cm. Raw they are slightly bitter, but once sautéed they turn nutty, slightly sweet and pleasantly crunchy. They keep well.

It takes patience: after the spawn run the substrate has to mature for several weeks before pins appear. It does best indoors, in blocks or bottles of sterilised sawdust; it can also be plugged into hardwood logs.

How to grow it

Preparation

Substrate
blocks: hardwood sawdust (fine and coarse) with approx. 20% supplement, e.g. bran, sterilised; outdoors: beech, elm or poplar logs
Spawn rate
1.5–2% on sterilised sawdust

Growing stages

  1. Spawn run (incubation)

    Temperature
    22–24°C
    Duration
    approx. 3–4 weeks
    Light
    darkness
  2. Substrate maturation

    Temperature
    22–24°C
    Duration
    4–8 weeks
    Light
    darkness

    The longer the maturation, the better the yield — do not rush it.

  3. Primordia formation

    Temperature
    13–16°C
    Humidity
    95–100%
    CO₂
    approx. 1,000–2,000 ppm
    Light
    50–200 lx

    Pinning is triggered by cooling and lightly scratching the top layer of mycelium.

  4. Fruiting

    Temperature
    13–16°C
    Humidity
    90–95%
    Duration
    5–8 days
    CO₂
    2,000–3,000 ppm
    Light
    200–500 lx

Harvest

Flushes
2
Between flushes
approx. 3 weeks

Keep the substrate very moist between flushes. Harvest whole clusters before the caps open. Yield: approx. 18–20% of fresh substrate weight.

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.
