The Blue Oyster Mushroom Kit includes a five pound bag of Blue Oyster Mushroom Kit mushroom mycelium growing on hardwood sawdust and soy hulls. The mycelium is the vegetative stage of the mushroom life-cycle; the mushrooms are the fruits. In the box you will also find instructions, a compostable tent, and chopsticks for supporting the tent. Each kit arrives ready to give way to the freshest Blue Oyster mushrooms you can find. Just follow the instructions to bring forth homegrown gourmet mushrooms.
