Optimizing Your Mycology Journey

Here are the steps we recommend:

  1. Allow a 7-10 day resting period before using your supplies, whether preparing or acquiring them.
  2. Your bags will arrive vacuum tight.
  3. This resting time helps ensure the sterility of your materials, which is crucial for success.
  4. Never store non colonized grain in refrigerators. 
  5. Do not use incubators
  6. Do not store bags in the shipping boxes. Place them on a clean shelf while observing.
