Product Information

Chestnut Mushroom Spawn For Commercial and Home growing

Our chestnut mushroom spawn is created in our clean room facilities in Brantford, Ontario. We ship our spawn anywhere in the US or Canada.

When buying spawn from us, you can expect:

  • Sterilized mushroom spawn (free of contamination)
  • Ready To Inoculate
  • Made With Organic Materials
  • Commercial High-Yielding Strains

How Long Does It Take To Ship?

Spawn customers should allow 4-weeks for their spawn order to be delivered. In some cases we will have the spawn in-stock and ship it immediately. Most of the time, however, the 4-week wait will apply.

Why Does It Take 4-Weeks?

To avoid shipping you out-of-date spawn we make your orders on-demand. We also test all spawn bags for vigour to ensure the final product is contaminant-free.

Planning for Commercial Growers

When sourcing spawn it’s a common occurrence in the industry – and necessary for your business to plan ahead. Securing your grain spawn for growing is essential to running a successful mushroom operation.
