Sterile Mushroom Grain Spawn (Oats)

This is a sterilized bag of Whole Oats that have been soaked and supplemented with calcium for thicker mycelial growth. This grain will work great as spawn for most mushrooms and it's even possible to grow Cordyceps right on these! 

These bags have a sterility guarantee. If you have not opened that bag at all we will happily replace it at no cost to you.

If you have any questions about whether this product will suit your project feel free to email us and ask us anything!

Note: These grains have not been inoculated with any mushroom cultures. We do sell colonized grain spawn which is recommended if you are a beginner mushroom grower.
