Master's Mix Wood-Lover's All-in-One Bag — 5lb | Ready to Inoculate

🍄 Everything You Need in One Bag

The That Mushroom Master's Mix All-in-One Bag is built for wood-loving species. It pairs a sterilized rye grain colonization layer with a nutrient-rich hardwood-based bulk substrate — no separate bulk spawning step, no mixing, no mess.

Just inject and wait.

📦 What's Inside

Each 5lb bag is split 50/50 between two layers:

• 2.5lb Sterilized Rye Grain — one of the most reliable and widely used spawn grains available, known for fast, even colonization and vigorous mycelial growth
• 2.5lb Master's Mix Substrate — a blend of non-GMO soy hulls and hardwood sawdust with added soil amendments, formulated specifically for wood-loving species

Both layers are autoclave sterilized in a professional mycology facility, sealed, and shipped fresh so your cultures hit the ground running.

✅ Key Features

• 🌳 Purpose-built for wood-lovers — soy hulls + hardwood sawdust blend outperforms CVG for species like Lion's Mane, Shiitake, King Oyster, and Oyster
• 🧪 Professional autoclave sterilization — eliminates contaminants so you don't have to worry
• 🌿 Non-GMO, sustainably sourced ingredients
• 💉 Built-in self-healing injection port — inoculate cleanly without opening the bag
• 🌬️ 0.2 micron filter patch — professional-grade gas exchange, contaminant-free
• 🦄 Unicorn grow bags — the trusted industry standard in polypropylene grow bags
• 📦 Ships fresh — we prep bags daily so what arrives at your door is always fresh and ready to perform
