I want to grow shitake mushrooms so i can dry them & always have mushrooms on hand. I have an article on how to grow them on oak logs. When u buy them they only last a few days fresh.
Mushroom logs are big over here - see them listed on the BST pages a lot. I've tossed the idea around quite a bit because DH loves mushrooms but, like you, I get frustrated by how short of a time they stay good when you buy them.
