To the right you can see four fuzzy pieces of mushroom in one of the 3 jars.
The growth looks good. For some reason, of the three jars, this is the only one showing any growth. The others are just sitting there.
I thought I had prepared all of the jars in the same way, but I must not have.
ALL of the mushroom pieces in this jar are showing growth, but NONE of the pieces in the two other jars are showing any growth at all.
Now if I could just figure out what I did right :)
