RMS Sterilized Grain – Clean, Ready-to-Use Sorghum Spawn for Mycology
The RMS Sterilized Sorghum Grain is a fully hydrated, sterilized grain spawn bag prepared in a controlled lab environment for mushroom cultivators who value consistency and efficiency. Made with medium-sized sorghum grain, this substrate offers an ideal balance of inoculation points, moisture retention, and nutrient content, making it a great choice for a wide range of gourmet and medicinal species.
Each bag is sterilized, sealed in a Sakato-brand grow bag with a 0.2 micron filter, and includes an injection port for easy inoculation with liquid culture—no need to open the bag until you’re ready to transfer.
Why Sorghum? A Balanced Grain for Spawn Production
Sorghum offers the best of both worlds: more inoculation points than rye and better overall hydration and nutrient content than millet. Its medium grain size supports even colonization, consistent moisture levels, and reliable nutrient delivery, making it a go-to for growers working with liquid culture or agar.
Includes Injection Port for Liquid Culture
Each bag features a built-in self-healing injection port, allowing cultivators to inoculate with liquid culture directly—no need to open the bag. The 0.2 Micron filter prevents the incursion of contaminants while promoting airflow to feed your mycelium.
Lab-Prepared & Contaminant Free
RMS grain is prepared in a dedicated lab facility using industry-standard sterilization techniques. Bags are filled, sealed, and sterilized in front of multiple laminar flow hoods within air-scrubbed rooms to help reduce contamination risks and improve consistency across batches.
