The first time I grew mushrooms (oysters) was a big lesson in patience. @Illicitmango you’re so right that it takes a bit before any real progress is showing but it’s still exciting to see the whole way through!
We have a great mushroom / mycology related thread for anyone who would like to join the fungus amongus 
Edit:
Same here, I started with PF Tek jars and lost most of them before they were ready to spawn. They did show me some pretty colors though - pretty colors of lipstick mold in the jars!
