    How To Grow

    Step-by-step Guide to Growing Hydrated Mycelium Material

    Step 1: Grow

    • Break up material

      Break up material

      • Before opening the bag, use your hands to hit exterior of the bag on all sides.
      • This helps save time breaking up the material before opening hte bag and adding to a bowl.
    • Add Flour and Mix

      Add Flour and Mix

      • Add material to a large bowl and continue to break up any chunks until the material is no longer white. 
      • Add 1.5 cups flour and mix well for 1 minute.
      • **If adding a Mix-in, add during this process.
    • Grow for 3-4 days

      Grow for 3-4 days

      • Add material to the growth form and pack down as you continue to add more layers.
      • Cover the form with plastic wrap or a lid. Grow for 5-6 days at 72 degrees F until material turns white again.

    Step 2: Pop + Pod, then Dry

    • Pop

      Pop

      • Flip the growth form upside down and tap until the grown part “pops” out of the form.
    • Pod

      Pod

      • Seal part in a roomy plastic bag with a cup of water to grow for 1 day to create a white, fuzzy overgrowth on the mycelium part.
    • Dry

      Dry

      • Remove from the overgrown part from the pod and place on a baking sheet.
      • Dehydrate the part at 180° F for 4-8 hours or until fully dry. The part will shrink in size!

    Testimonials

    We would recommend this material to makers in general that are looking for an eco-friendly alternative to polystyrene

    Iyvone

    Through this process, I've developed a relationship with objects that is defined by a sense of cultivation. I would love for this approach to propagate, for material culture to be 'consumed' less and 'cultivated' more.

    Kamilla

    I started experimenting...around 2015. The generous guidance and advice I've gotten from them has been invaluable. I love that I am collaborating with a living microorganism and find myself having a relationship and affection for the material.

    FAQs

    How long does it take to grow?

    GIY material needs 3-4 days to grow after hydrating, then 5-6 days to grow once placed into your growth form. Total about is 7-10 days depending on the speed of growth!

    Can I use my own growth form?

    Yes, absolutely! We encourage you to make your own growth form because it helps understand the mycelium material's properties. You can learn how to make your own growth form here: [LINK]

    Is it beginner friendly?

    Yes, our GIY material is often people's first introduction to working with biomaterials! You just need to add flour and water, and sit back and let the mycelium grow :)
