Basic Cultivation Guidelines: The Black Pearl King is known for its adaptability and relatively straightforward cultivation. Our premium grain spawn ensures fast and complete colonization of your chosen bulk substrate when provided with the right conditions. Recommended Substrates: Hardwood sawdust (HWFP), straw, Master's Mix (soybean hulls & hardwood sawdust), or other compatible lignocellulosic materials. Inoculation: Mix the grain spawn thoroughly with your pasteurized or sterilized bulk substrate at a typical rate of 5-15% spawn to substrate by wet weight. Colonization: Temperature: 70-75°F (21-24°C). Duration: Typically 1-3 weeks for full colonization, depending on substrate and conditions. Keep in a dark place. Fruiting Initiation (Pinning): Temperature: Introduce to cooler temperatures, around 60-68°F (15-20°C). Humidity: Increase to 85-95%. Light: Introduce indirect light (enough to read by). Fresh Air Exchange (FAE): Increase significantly. Fruiting & Harvest: Maintain high humidity and good FAE. Mushrooms typically develop 1-2 weeks after pinning. Harvest when caps begin to flatten or just before the edges curl upwards. Expect beautiful clusters of richly colored mushrooms with satisfyingly dense, meaty stems. Note: These are general guidelines. Optimal conditions may vary slightly. We encourage you to research specific teks for your chosen substrate and setup. Storage & Handling: Upon arrival, inspect the bag for any signs of damage or contamination. If not using immediately, store the grain spawn in a refrigerator (around 35-40°F or 2-4°C).
