We offer you Phase III mushroom substrate/compost : A15 from Sylvan (white mushroom) and Heirloom from Amycel (brown mushroom). Other strains are also available on request. The mushroom substrate is pressed into packages and shipped in 40 ft reefer containers. We developed two different methods of loading so we can offer our customers a choice in what method suits best to their situation.

Han is an entrepreneur in heart and soul. He became part of his father’s company at the age of 20 and has been self-employed ever since.
