      • Mix 4 Tbsp flour and 3 cups water into a slurry then pour into the bag.
    • Seal and Shake

      Seal and Shake

      • Reseal the top of the bag above the filter patch.
      • Shake it! Mix the bag for 1 minute to hydrate thoroughly.
    • Grow for 3-4 days

      Grow for 3-4 days

      • Let grow until white in a clean area, out of direct sun, with a room temperature at 72° F.
      • Allow an additional day of growth if not wellgrown after 4 days.

    Step 2: Grow

    • Break up material

      Break up material

      • Add material to a large bowl and break up all the chunks. We call this step “regrinding.”
      • Add 4 Tbsp flour for nutrition
      • Add the sculpting mix and mix well for 1 minute. Drizzle a little extra water if the mix seems too dry.
    • Pack the Form

      Pack the Form

      • Add material to the growth form and pack down as you continue to add more layers.
      • Place a sturdy flat sheet on top of the form and tap all over to smooth the fill surface.
    • Grow for 5-6 Days

      Grow for 5-6 Days

      • Cover the form with plastic wrap or a lid and poke a few small holes for respiration.
      • Grow until fully white again in a clean area with the same growth conditions as step 1.

    Step 3: Pop + Pod, then Step 4: 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 :)
