Starter Guide: Fruiting Colonised Substrate Blocks

You’ve received: a fully colonised fruiting block in a Unicorn bag.

What you need:

  • A clean fruiting chamber or grow tent
  • High humidity (85–95%), indirect light (12/12), and fresh air exchange

Instructions:

  1. Inspect the block: It should be firm, white with mycelium, and may show signs of primordia (tiny pins).
  2. Cut open the bag:
    • For Oysters & Lion’s Mane: slice a large X or remove the top of the bag.
    • For Shiitake: remove from the bag and cold shock (24 hrs in fridge), then place in fruiting conditions.
  3. Mist and monitor: Maintain humidity and fresh air exchange. Mist as needed to prevent drying.
  4. Harvest when mushrooms reach mature size—usually 5–10 days from pinning.
