Easy to Follow Mushroom Grain Instructions:

1: Grain Setup</strong>

• Unpack your Grow Bag and place it in a clean, stable environment.
• Ensure the area is free of contaminants and has a consistent temperature of 65-75 degrees for mushroom growth.

2: Liquid Culture Inoculation

• Sanitize your hands and the needle of the syringe containing mushroom spores or liquid culture.
• Carefully inject the spores/liquid culture into the Grain through the bag. Place tape over the needle insertion point immediately following.

3: Incubation

• Store the bag in a dark, warm place where the temperature is consistent.
• Avoid disturbing the bag to let the mycelium colonize the grain fully.

4: Mixing for Mushroom Fruiting

• Once white colonization has overtaken at least 60% of the grain, break it up and mix it with a mushroom fruiting substrate or Mushroom Grow Kit.
• Be patient, harvest is only a few weeks away!
