RMS Fast Fruiting Mix – Sterilized Substrate for Gourmet Mushroom Cultivation

The RMS Fast Fruiting Mix (Master's Mix) is a ready-to-use, sterilized substrate made for cultivating fast-fruiting gourmet mushrooms like oyster and lion’s mane. Formulated with a trusted 50/50 blend of red oak and soy hulls - commonly known as Master's Mix, this mix delivers the nutrition, hydration, and structure needed to support rapid colonization and high-yield flushes.

Hydrated to field capacity and sealed in Unicorn-brand grow bags with 0.2 micron filters, this substrate is ideal for growers looking to grow gourmet mushrooms in the bag or in grow tents. 

Also known as Master’s Mix, this substrate is a go-to choice for growers looking for fast colonization and consistent results with wood-loving species.
