Sterilized Substrate for Slow-Fruiting 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.
