A robust staple for advancing your cultivation skills. The Grey Oyster mushroom is celebrated for its aggressive colonization, high yields, and culinary versatility. While the species is extremely beginner-friendly, this plate culture from the Redwood Mushroom Supply (RMS) laboratory is perfect for intermediate growers looking to refine their sterile techniques and advance beyond liquid cultures.
Our Grey Oyster strain produces impressive, dense clusters of off-white to grey fan-shaped caps. It is highly valued for its wide temperature tolerance, making it a reliable performer for year-round cultivation. In RMS grow trials, this resilient strain consistently produced 1-2 lbs of fresh mushrooms per 5 lb block and demonstrated a strong ability to produce multiple full flushes on both hardwood and straw substrates.
We provide laboratory-grade agar cultures expanded from early-generation slants to ensure peak genetic vitality:
For optimal results, transfer a 1cm x 1cm agar wedge to sterilized grain jars or bags using a Still Air Box (SAB) or Laminar Flow Hood. Once the grain is fully colonized, use it to inoculate your final substrate at a 5-10% ratio. Side-fruiting from bags in a high-airflow environment is the recommended method for achieving the best cluster formation.
