Dont pick at it , dont play with it THROW IT UNOPENED AWAY .
The jars were 100% sterile until I started to grow the mushrooms. They are now producing beautiful mushrooms, with no sign of contamination.(after picking the dot off the cake).
Can you see bacteria ? Or mold spores ?
Then HOW do you EVER know if there is bacteria or mold spores on your mushrooms if you cannot visiblity seem them.
PEACE & LOVE
