What It Looks Like
Wispy, grey-white fluffy growth that spreads over substrate surface like cobwebs
Recommended Action
If caught early, spray directly with 3% hydrogen peroxide. Increase FAE dramatically. May survive if treated immediately. Isolate from other grows.
How to Identify
- 1Much wispier/fluffier than mycelium
- 2Grows faster than healthy mycelium
- 3Grey tint vs bright white mycelium
- 4Floats above substrate surface
- 5Collapses when misted (mycelium stays firm)
Common Causes
- •High humidity with poor air circulation
- •Stagnant air in fruiting chamber
- •Contaminated casing layer
- •Over-misting without FAE
Prevention Tips
- ✓Maintain good fresh air exchange
- ✓Do not let humidity stagnate
- ✓Use clean casing materials
- ✓Balance misting with air flow
