As soon as I got the oyster mushroom spawn filled toilet papers home, I put them in dark closet in my kitchen as instructed in step 5, Place this bag in a dark closet at 70 degrees where it will become covered in mycelium.

Three weeks have passed and here are the results.

So far so good, the toilet paper is still recognizable, but things are progressing.

Step 7. Place the bag in the refrigerator for 3 days.
Following their 3 week stint in the dark, the result of which you can see above, it was time to move the rolls the refrigerator for a three day cold treatment.

Next up, moving on to step 8 – Remove bag from refrigerator and open the top of bag to breathe.
