What temperature does it need?
For Oyster mushrooms we generally say… If you are comfortable, they will be comfortable, but in the case of shiitake they will become dormant… as shiitake like to run cool.
In nature, they grow best in fairly northern latitudes, where in winter it will be in a snow-covered forest within a frozen log. In these regions, summer is often quite hot, with temperatures in the 30’s. Their fruiting season is late autumn or early spring as they’re responding to sharp changes in temperature and humidity. Hence the tip on creating the autumn storm, and chilling it in the refrigerator.
If you have an air conditioning/heat pump, be aware that this will dry the air. Please try and maintain a humid environment for your shiitake-farm.
