Key Features:
- Easy to Grow: Beginner-friendly design requires minimal effort.
- Organic & Non-GMO: USDA-certified organic substrate ensures natural growth.
- Delicious Flavor: Produces plump, dense, shaggy mushroom clusters suitable for various culinary uses.
- Multiple Harvests: Expect 0.5-1.5 lbs from the first harvest, with subsequent smaller flushes possible.
- Quick Results: First harvest typically ready in 14-21 days after pinning.
2. Setup Instructions
Follow these steps to initiate the growth of your Lion's Mane mushrooms:
- Prepare the Box: Locate the perforated line on the front of the kit box. Carefully open the front panel along this line.
- Cut the Plastic Bag: Inside the opened box, you will find a plastic bag containing the mushroom substrate. Using a sharp knife, make a large 'X' incision into the plastic bag where the mushrooms are intended to grow. This opening allows for air exchange and mushroom fruiting.
- Fill the Sprayer: The kit includes a small sprayer. Fill this sprayer with clean tap water.
- Initial Spraying: Mist the 'X' incision in the plastic bag with the filled sprayer. Apply a few pumps to ensure the exposed substrate is moist.
- Placement: Place your kit in an area with indirect light and stable room temperature (ideally between 65-75°F or 18-24°C). Avoid direct sunlight or drafts.

3. Operating & Daily Care
Consistent moisture is crucial for successful mushroom growth. After initial setup, mist the exposed substrate 2-3 times daily with the provided sprayer. In dry climates, more frequent misting may be necessary to maintain humidity. Ensure the substrate remains visibly moist but not waterlogged.
Growth Timeline:
- Pinning: Small mushroom formations (pins) typically appear within 7-14 days.
- Rapid Growth: Once pins appear, mushrooms will grow rapidly over the next 7-10 days.

4. Harvesting
Harvest your Lion's Mane mushrooms when their caps begin to flatten and the spines (teeth) are well-defined but still firm. This usually occurs around 14-21 days after the first pins appear.
- Identify Readiness: Look for signs of maturity, such as flattening caps and developed spines.
- Harvesting Technique: Gently twist and pull the entire mushroom cluster from the substrate. Avoid cutting, as twisting helps prepare the block for subsequent flushes.

5. Maintenance & Subsequent Flushes
After your first harvest, the kit can often produce additional flushes of mushrooms, though these may be slightly smaller. To encourage further growth:
- Re-hydration: After harvesting, you can soak the entire substrate block in cold water for 4-6 hours to rehydrate it.
- Continue Misting: Return the block to its original position and resume daily misting 2-3 times a day.
- Outdoor Cultivation: For extended life, spent indoor kits can be planted outdoors in a shady, moist area (e.g., under a tree or in a garden bed with mulch). This can encourage additional fruiting over several months.
Storage:
If you are not ready to use your kit immediately upon arrival, it can be stored in the refrigerator for up to 3 months. This will slow down the mycelial growth and preserve the kit's viability.

6. Troubleshooting
While the North Spore kit is designed for ease of use, occasional issues may arise:
- No Growth/Slow Growth: Ensure adequate humidity and temperature. The ideal temperature range is 65-75°F (18-24°C). Increase misting frequency if the substrate appears dry.
- Mushrooms Drying Out: This is often due to insufficient humidity. Increase misting or consider placing the kit in a humidity tent (e.g., a clear plastic bag with small holes) if your environment is very dry.
- Contamination (Unusual Colors/Mold): If you observe green, black, or other unusual colored molds, the kit may be contaminated. While rare, this can happen. Discard the contaminated kit to prevent spread.
- Mushrooms Growing from Incorrect Areas: If mushrooms start growing from unintended spots (e.g., the bottom of the box), it indicates moisture has reached that area. Ensure the kit is placed on a dry surface and that the primary 'X' incision is the main point of moisture application.
