Thick Cultures Quality Control Center

Welcome to our Quality Control Center where we document every test of our mushroom cultures that we conduct. When we create new master cultures from spores, test our master cultures for viability, test production batches for contamination, or investigate customer concerns, the full process is posted here: testing methods, observations, contamination results, viability assessments, and photo evidence. We conduct these tests to ensure every culture leaving our lab meets our standards for purity and viability.
