Skip the guesswork and start from a proven, healthy culture. Our 100mm Colonized Agar Plates are grown from cloned mushroom cultures and fully colonized so you can move straight into transfers, grain inoculation, or culture expansion.

We pour and handle every plate using sterile technique under a HEPA-filtered flow hood, then quality control test cultures to help ensure you’re receiving clean, vigorous mycelium you can trust. Whether you’re building a culture library or scaling up spawn, these plates are a dependable starting point for consistent results.
