This album on growing mushroom spawn is based on the wonderful workshops of Guerilla House where we learned to grow mushrooms on straw, and wooden logs, and make spawn for seeding the straw and logs, at very low cost. To grow spawn you need spores or mushroom parts, preferably the 'stem'. Placed on a growing medium they soon begin to sprout mycelium.

Sprinkle the box regularly, keeping it damp, cool and in a shady place.
You can pasteurize the cardboard with boiling water in a closed icebox. Pasteurized growing media are important while the mushroom is spreading through the spawn material because with all the food available at this stage, other competing organisms, ubiquitously present all around us, in our food, on our hands and in the air, can take root and outcompete our food mushroom. Once the material is mostly colonized its safer to expose the spawn to the next stage of growing medium.

Once you have cultured some spawn you can use it to seed the growing medium on which you wish to grow mushrooms and see them fruit. A favorable growing medium for the mycelium provides the greatest yield and success rate with shop bought spawn. The medium can be treated by sterilizing it or pasteurizing it depending on the degree of removal of other organisms you are aiming for. The Guerilla House 'Low Tech Shrooms' workshop takes one through all the moves to be able to practice this exciting form of agriculture with minimal setup costs. You can move on to the other photo albums of the workshop, on growing mushrooms on straw and in the garden, and on growing oyster mushrooms on wooden logs. In both cases versatile Oyster mushrooms were used.

I live in Plumstead, which is quite a tough place to garden. Anyone that you know of tried to plant a Miyawaki forest in Cape Town? I'm tempted to give
