You receive living, actively growing, axenic cell culture, entirely free of other strains or contaminating organisms, for further propagation. Our pure cultures are custom-made and produced freshly after ordering - in a class 100 clean room environment on a solid nutrient medium (MEA) based on plant-derived raw materials. The pure culture needs around 2-3  weeks until its mature enough for shipping. The culture is supplied in special cell culture flasks (Filling volume: 15 ml culture medium, Growth area: 25 cm², Measurements: L x W x H = 79,7 x 42,6 x 26,53 mm) with breathable, hydrophobic membrane. This special design prevents introduction of contaminants and enables optimum gas exchange thanks to the high air flow rate of the membrane. With this packaging, the mushroom culture can withstand longer shipping distances and time without compromise of quality or germination ability. 

This product is intended for professional production of grain spawn for further propagation of this strain of fungi. Working with pure cell cultures requires detailed mushroom cultivation skills. For beginners and hobby growers we recommend starting with grain spawn or sawdust spawn.
