Thanks for the detailed reply.
I am just starting out growing and tried a couple of TEKs, the brokeboi which is basically what you described as steaming the jars in the pot. Unfortunately, I had that issue with the rice becoming overly wet, and having the sour smell and the mycelium basically...
I ordered twice from them; never had an issue but it usually takes a week/week and a half for the goods to arrive.
I've had those shots; personally, I would recommend the dried shrooms over the shots.
