lots of useful information on there about cultivating mushrooms,
soil wont work that well, i had some leftover spores put it in soil and got the smalllest mushrooms, think about using a rice type medium and remember everything has to be sterile.
I have two cultures going right now. Both of them are made up of;
potting soil
wheat noodles
cracked corn
coffee grounds
Old chex mix I had laying around
The white "fuzz" mycelium attacked the wheat noodles and chex mix first and is slowly starting to move onto the corn and coffee ground. I'm gonna be gone for two days so i should see a vast difference when I get back.
My sanitation barrier is only a sheet of plastic wrap with pinholes over the inoculation sites. So far as I can tell there are no offensive odors (other than old soggy corn) and I dont see any contamination (molds, bruising, etc.)
The temperature constant falls between 68-80* fahrenheit.
A little off the subject... I use to go pick pounds upon pounds of chantrells every spring in Washington... No magic mushrooms, but the best damn shrooms to cook with in my opinion
