From the very first Mushroom Days to an increasingly automated and international future.
In this video, Johan Janssen from Hollander Spawn B.V. reflects on how far the mushroom industry has come. Having experienced the very first Mushroom Days as a sixteen-year-old, he has seen the sector develop over decades.
He highlights how mechanisation continues to advance, especially in picking aids and related improvements. At the same time, mushroom cultivation is becoming more automated and increasingly international, with more companies from around the world entering the Dutch market.
Champignondagen brings that development together. It is where experience, innovation and international expertise meet.
Watch the video and discover Johan Janssenโs view on the past, present and future of mushroom cultivation.
