Troubleshooting Mushroom Growth: Common Issues and Solutions
Mushroom growing can come with a variety of unexpected hurdles. Let’s break down some common problems and practical solutions to help you troubleshoot.
Common Problems and How to Fix Them:
Slow or Stalled Mycelium Growth
Potential Causes: Substrate is too dry, temperatures are too low.
Solution: Make sure your substrate has the right moisture content—aim for a "field capacity," meaning that a handful of substrate should not drip when squeezed but release a few drops under pressure. Optimal temperatures vary by species but generally fall between 21-26°C for most common mushrooms.
Contamination (Green Mold or Bacterial Blotch)
Potential Causes: Improper sterilization, excessive moisture.
Solution: Sterilize all tools, use gloves, and work in a clean space. Avoid overly humid conditions that promote bacterial growth. Maintain relative humidity levels between 85-90% during the fruiting phase but ensure proper ventilation.
Mushrooms Won’t Pin
Potential Causes: Improper temperature, low humidity, insufficient light.
Solution: For pinning to occur, most species need a drop in temperature (typically to around 18-21°C), adequate humidity, and indirect light. Adjust these parameters to stimulate fruiting.
