Blue oyster (Pleurotus ostreatus var. columinus) is a productive strain that colonizes fast, making it great for beginners. Expect several harvests. Blue oysters taste great, too. Enjoy its meaty texture and rich, umami flavour.

What is grain spawn?

Grain spawn is sterilized grain that has mushroom mycelium growing on it. You can mix grain spawn with a substrate to grow mushrooms in a bag or container. This is how mushroom kits at Folk Fungi are created.

Contents

Growing mushrooms with grain spawn is a bit more involved than growing with a kit. If you want to learn how to use grain spawn, we suggest our Growing Mushrooms for Beginners course.
