Organic Shiitake Grow Kit XXL: grow Shiitake at home
Our large Shiitake kit is an organic hardwood substrate block, inoculated at our mushroom farm in Schleedorf. At home you let the block brown and then start fruiting with a simple trick. Shiitake from your own block taste intense and savoury – perfect for the pan, wok and soup.
How it works
- Leave the block in its bag at room temperature for 4–6 weeks until brown – don’t move it.
- Put it in the fridge, still closed, for at least 48 hours.
- Unwrap it and submerge it in cold water for about 4 hours.
- Place it on a plate without the bag and harvest just before the caps open flat.
Ideal conditions
- Fruiting: 10–25 °C
- Humidity: above 85 %, e.g. bathroom or cellar
- Bright but out of direct sunlight
Good to know
- Between flushes, give it 2–3 weeks of rest, then another water bath.
- Simply scrape off any green patches (Trichoderma).
- The spent kit is a valuable organic fertiliser.
