SINGLE-SOURCE SUBSTRATE

This substrate blend of our single-source mushroom compost and local organic straw is hydrated and sterilized to perfection! With this substrate you will be ready to grow gourmet, medicinal and active fungi species.

You can inoculate this bag with myceliated grain spawn, or even transfer an agar plate or liquid culture directly since this blend has sufficient nutritient content to support the entire life cycle.

This bag is folded and sealed with a reusable zip tie, allowing the bag to be reused as well. This also makes it possible to open and seal the bag without using an impulse sealer. Click on "Sustainable Cultivation SOP" at the bottom of this page to view our practices for cultivation with zero single-use plastic.

Listing is for a single 5lb bag of substrate, please inquire for wholesale pricing!
