Mushroom Signals book

Mushroom Signals is the essential, practical guide to optimal mushroom cultivation. The book was written by Mark den Ouden, an internationally recognised consultant and trainer in the mushroom sector. In Mushroom Signals, his extensive knowledge is shared in a practical, accessible and highly visual way, with the aim of helping others in the sector expand and improve their skills.

The Mushroom Signals concept is based on learning by applying the principle of ‘look-think-act’: what do I see in practice, what could it mean and what can I do next?
