How much to buy?

Use an online volume calculator . For example, the volume of your mold 30cm x 28cm x 3cm is 2.52 litres.

Our sawdust 3 KG  and hemp hurd 3KG are roughly 5 Liters in volume.

Upon Arrival:

• After receiving it, you might need to store the product for an additional 2-3 days. Begin usage when you notice white mycelium growth.
• There’s no need to wait for complete coverage; when 10-20% of the bag turns white, it’s ready for the next step.

   Storage upon arrival

• Place the bag in an open space, ensuring it stands upright and remains fully unfolded (the white part in the bag is the air filter, which allows the mycelium to breathe).
• Avoid exposure to direct airflow from fans, air conditioning, or heaters, and prevent direct sunlight. It’s best not to store inside cupboards or boxes.

Usage Instructions:

• Once you observe fluffy mycelium growth, break up the ingredients inside the bag.
• Open the bag and start transferring the mixture into your mold:
  • For larger molds, avoid packing the mixture too tightly.
  • For smaller objects, you can compact the mixture slightly.

Important Notes:

• Mycelium begins to harden from day 10 post-manufacturing, which can make it challenging to work with. We advise using the substrate before this hardening occurs.
• Order only when you’re set to start your project. Upon readiness, use the entire substrate promptly or within a few days.
• To decelerate the mycelium’s growth rate, you can refrigerate the medium.
• If not utilizing the entire substrate immediately, reseal the bag and refrigerate. Before reuse, bring the mycelium back to room temperature.

Product Benefits: We supply sterile hemp hurd or Sawdust at field capacity (hydrated), fortified with nutrients, to guarantee rapid colonization.

Please note that Hemp hurd colonizes fast, but sawdust is better for intricate and smaller molds. We find the sawdust medium pretty resilient when demolding and is not as brittle as the hemp hurd from the edges.
