Bag culture is a complex process requiring specific conditions of controlled temperature, light and moisture. The inexperienced mushroom grower would be advised to start with growing shiitakes on logs .

Many strains of shiitake can tolerate a wide range of temperatures. It’s possible to successfully fruit them when it’s snowing outside and also in temperatures above 30 degrees Celsius .
