Without a doubt my favourite way to cultivate oyster mushrooms. Perfect for growing all side fruiting oysters.
The mycelium devours the straw or sugar cane mulch while it prepares to launch masses of fresh fungi from each of the numerous holes in the bucket. This design allows for it to be easily harvested and form beautiful clusters.
Either method of cold water lime pasteurisation or hot water pasteurisation can be used for this project. Sugar cane mulch is cheap and accessible where I live but you can use the straw product of your choice taking care to avoid substrates full of viable seed as they may sprout.
