An outline of the main stages. For detailed, farm-specific advice, talk to our team.
- 01
Chop and soak the straw, then pasteurise or sterilise it and drain to the right moisture
- 02
Mix the spawn evenly through the cooled substrate and fill bags or beds
- 03
Keep bags warm and dark while the mycelium runs through the substrate
- 04
Open or slit the bags, raise humidity and give fresh air and light for fruiting
Spawn handling
Getting the best from your spawn
Use it fresh
Plan spawning close to delivery and use the spawn as soon as practical.
Keep it cool and shaded
Store in a clean, cool, shaded place — never in direct sun or a hot vehicle.
Check before use
Look for healthy white mycelium; don’t use bags with unusual colours or smells.
Mix evenly
Break up the spawn and spread it evenly through clean, cooled substrate.
Important DisclaimerSpawn Lab is responsible for the quality of the spawn supplied. Mycelial run, crop development and final mushroom yield depend on substrate quality, environmental conditions, cultivation practices, hygiene, handling and other factors beyond our control.
