Hello everyone! I decided to try the PF-tek with 4 spawn jars I had. br br But I faced with some issues. I had jars with a narrow neck. A logical question arises: what to do in such situation? br br The first thought was to break them. But after googling I found out an easy way how to cut the jar by using string, alcohol, lighter and cold water. It took about 15 minutes to trim 4 spawn jars and remove mushroom cakes safe and sound.
