*Primordia are induced by a shock. For most mushroom species, this is done with a thermal shock, which is defined by the minimum temperature during the day-night cycle.
†Mushroom weight immediately after harvesting, and wetted substrate weight prior to inoculation.
Important remark: the cultivation guidelines in our technical data sheets are a compilation of the data given to us by experienced cultivators. Individual differences in the cultivation conditions can seriously affect the results.
