🌟 WHY RYE
━━━━━━━━━━━━━━━━━━━━━━━━━
Rye (Secale cereale) is the gold-standard grain for mycelial spawn: superior water retention, high nutrient density, fast and even colonization. Each kernel is hydrated inside but dry outside — perfect for shake-and-break technique without wet pockets or stalling. Robust mycelium, lower contamination risk compared to wheat or millet.

━━━━━━━━━━━━━━━━━━━━━━━━━
🔬 STERILIZATION & SAFETY
━━━━━━━━━━━━━━━━━━━━━━━━━
High-pressure autoclave cycle for medical-grade sterility. The SHIP port lets you inoculate without ever opening the bag. The 0.2-micron filter blocks mold and bacteria while allowing the O₂/CO₂ exchange essential for mycelial respiration.

━━━━━━━━━━━━━━━━━━━━━━━━━
📋 HOW TO USE
━━━━━━━━━━━━━━━━━━━━━━━━━
1. Wipe the SHIP port with 70% isopropyl alcohol.
2. Inoculate 3–5 ml liquid culture or spore solution with a sterile syringe.
3. Store in a dark place at 68–75 °F (20–24 °C).
4. Gently shake every 3–4 days to distribute mycelium.
5. Full colonization in 10–21 days (varies by species).
6. Transfer to bulk substrate (straw, sawdust, compost) or use in monotub setup.
