Spore cultivation requires precise conditions. A few things to check:
- Sterility: did you work in a clean environment? Contamination is the most common reason for failure.
- Temperature: most species need 24-28 degrees C for colonisation.
- Inoculation method: how did you introduce the spores to the substrate?
