Logs vs Blocks
| Logs | Low-tech, outdoor, long timeline, multiple seasons possible. |
|---|---|
| Blocks | Faster, cleaner, better for indoor controlled fruiting. |
| Kits | Best if you want to learn harvest timing before inoculation work. |
Outdoor Log Method
- Use suitable hardwood logs.
- Inoculate with shiitake spawn.
- Seal holes if using plug spawn.
- Stack in shaded, moist conditions.
- Be patient through colonization.
Indoor Block Method
Prepared blocks reduce the hardest parts of shiitake cultivation. Follow the supplier's fruiting instructions, keep humidity stable, and avoid stagnant wet conditions.
Harvest and Rest
Harvest when caps are opened but still fresh and firm. After a flush, blocks or logs need a rest period before the next production cycle.
