Our mushroom substrate bundles make it easy to stock up. Each bag contains our sterilized Simple Mix substrate of 75% coir and 25% vermiculite, sealed in a filter-patch bag and ready to use.
Choose 2000cc for small batches, 4000cc for a standard tub, or 6000cc for filling larger monotubs. Combine with colonized grain spawn from our grain and substrate range, or start from scratch with a liquid culture syringe.
