"Siemen and Mark showed me everything from coffee collection, substrate preparation, room conditioning, harvesting, product development and a whole lot more. Therefore I strongly recommend everyone who thinks about starting a business as a mushroom grower, everyone who likes to grow mushrooms at home, or everyone who is interested in environmental issues and sustainability, to gain knowledge and be inspired by the awesome people at RotterZwam."
