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.
