Organic Corn Grain Spawn 1kg/2kg Autoclave Sterilized • SHIP Port • Oyster Shiitake Reishi Lions Mane

🍄 Professional 1kg/2kg grain spawn: certified organic corn, autoclave-sterilized, ready for immediate inoculation. Self-healing SHIP port + 0.2-micron filter for contamination-free colonization.

━━━━━━━━━━━━━━━━━━━━━━━━━
✅ WHAT'S INSIDE
━━━━━━━━━━━━━━━━━━━━━━━━━
• 1 bag of 1kg/2kg organic yellow corn
• Full autoclave sterilization at high pressure (250°F / 121°C)
• Professional Self-Healing Injection Port (SHIP)
• 0.2-micron micropore filter patch for sterile gas exchange
• Ready to use — zero prep or cleanup required

━━━━━━━━━━━━━━━━━━━━━━━━━
🌟 WHY CORN WINS
━━━━━━━━━━━━━━━━━━━━━━━━━
Large kernels prevent compaction and ensure optimal airflow throughout the bag. The "shake and break" process becomes effortless and highly effective, accelerating colonization by up to 40%. Each kernel is hydrated to the core with a dry surface — the perfect balance to block bacteria while providing the deep moisture reserves mushrooms need for heavy, consistent flushes.

━━━━━━━━━━━━━━━━━━━━━━━━━
🔬 GUARANTEED STERILITY
━━━━━━━━━━━━━━━━━━━━━━━━━
Every bag undergoes an intensive autoclave cycle to achieve medical-grade sterility. Zero pesticides, zero chemical contaminants. The SHIP port lets you inoculate without ever exposing the substrate to open air, while the micropore filter keeps unwanted molds and bacteria locked out during the entire colonization phase.

📋 QUICK START GUIDE
━━━━━━━━━━━━━━━━━━━━━━━━━
1. Inoculate 2–5 ml of liquid culture or spore solution through the SHIP port
2. Store in darkness at 68–77°F / 20–25°C (adjust for species)
3. Perform "shake and break" when colonization reaches 30–40%
4. Wait for full colonization (7–21 days depending on species)
5. Transfer to bulk substrate or fruit directly from the bag

━━━━━━━━━━━━━━━━━━━━━━━━━
✨ PERFECT FOR ALL SPECIES
━━━━━━━━━━━━━━━━━━━━━━━━━
Ideal for aggressive colonizers like Pleurotus ostreatus (Oyster), but equally excellent for Hericium erinaceus (Lion's Mane), Ganoderma lucidum (Reishi), Lentinula edodes (Shiitake), and dozens of other gourmet and functional species. Corn offers balanced nutrition and space for rapid mycelial expansion.

🍄 STORAGE & SHELF LIFE
━━━━━━━━━━━━━━━━━━━━━━━━━
Store in a cool, dry place (59–68°F / 15–20°C) until use. Once inoculated, keep in darkness until fully colonized. Do not refrigerate before inoculation.
