RMS Hardwood Mix – Sterilized Substrate for Gourmet Mushrooms

The RMS Hardwood Mix is a sterilized, ready-to-use substrate formulated for slower-fruiting gourmet species like shiitake, maitake, and reishi. Made from a balanced blend of oak sawdust and wheat midds, this mix offers the structure and nutrition needed for longer colonization cycles and extended fruiting timelines.

Hydrated to field capacity and packaged in Sakato grow bags with 0.2 micron filters, this substrate is designed for in-bag fruiting and performs reliably in controlled environments, making it an excellent choice for growers seeking steady, high-quality yields over time.

Features

Why Choose RMS Hardwood Mix?

• 🌳 Oak & Wheat Midds Formula – Blended for slower-growing mushrooms that prefer a more gradual nutrient release.

• 🍄 Ideal for Shiitake, Maitake & Reishi – Supports extended colonization and delayed fruiting cycles.

• 💦 Hydrated to Field Capacity – Ready to inoculate—no need for soaking or mixing.

• 📦 Reliable, Professional Packaging – Sterilized and sealed in Sakato grow bags with 0.2 micron filters for clean colonization with an outer bag for additional protection.

• 🧪 Great for Long-Term Yields – A substrate you can count on for slow, steady fruiting performance.

Usage

For In-Bag Fruiting:

Add at least 10% fully colonized grain spawn by weight in clean conditions. Reseal the bag and mix thoroughly to ensure even distribution. Once fully colonized, cut slits or open the bag to initiate fruiting.

Additional Info

Designed for Slow-Fruiting Species

This oak and wheat-based substrate is ideal for mushrooms that require a longer incubation period, such as shiitake or reishi. The lower nutrient content supports a more controlled colonization process, helping reduce contamination risks in long runs.

Fully Hydrated & Sterilized

Each bag is hydrated to field capacity and professionally sterilized, so it’s ready to use out of the box. No additional steps or additives are required—just inoculate, seal, and incubate.

Packaged in Sakato Grow Bags with 0.2 Micron Filters

The substrate is sealed in Sakato-brand polypropylene bags with 0.2 micron filter patches for safe gas exchange and contamination resistance. These bags are trusted by cultivators for their durability and in-bag fruiting performance.

Storage Recommendations

Store unopened bags in a cool, dry place, away from direct sunlight. Use promptly for best results and to maintain substrate quality.
