Oberon: 6lbs Organic, Sterilized Wood-Based Substrate

Our Wood-Based Substrate is perfect for gourmet or culinary mushrooms. Our proprietary blend contains a mix of sawdust and soy hulls. The hydration of every batch is PH tested and brought to field capacity. We use 100% recyclable Unicorn bags.  Each bag is sterilized, then cooled and sealed in front of our MERV-rated, HEPA filtered flow hood. Our substrate bags are available to be used immediately and are shelf-stable for up to 12 weeks from the batch date.
