How It Works

1. Sanitise your hands and workspace. Cut open the front panel of the box to expose the bag.
2. Cut a small “X” or slit in the front of the bag where you want the Blue Oyster mushrooms to form
3. Place the block in a humid fruiting environment with fresh air exchange and indirect light.
4. Blue Oyster mushrooms will begin forming from the cut. Continue misting daily. Harvest when the fruits are mature. Twist and pull gently, or cut cleanly at the base.
