The process:
All our grain goes through a rigorous sterilization process, using a lab-grade, digitally controlled autoclave to ensure precise control over time and temperature. This guarantees that your spawn is fully sterilized without being overcooked, which is crucial. Once sterilized, the bags are removed from the autoclave in a clean room, sealed, and inspected for any potential issues. We then vacuum-package each bag with desiccant and sterile alcohol pads to keep them fresh and ready for inoculation.

We take pride in our products and stand behind them with a guarantee, so you can cultivate your mushrooms with confidence.
