Mushroom cultivation is a technical process. As mushroom professionals often talk in a technical language, a few of these terms will first be explained.
In the early years of mushroom culture in the Netherlands, compost was scooped into the mushroom trays and then inoculated with spores. A nine week wait followed, until the mycelium spawned sufficiently, flushing started and the grown mushrooms could be harvested by hand.
The cultivation process hasn’t changed that much, but the way the successive steps are performed differ immensely. Hardly anything is done by hand anymore in modern mushroom farming.
