Tight is better for keeping out contaminants. The whole idea with PF-Tek is to give your mushroom spores an advantage over contaminants by allowing them to fully-colonize a sterile environment before being introduced to the not-so-sterile fruiting chamber. If your lid is too loose, contaminants can enter the jars and cause your spores to lose their edge.

[/quote]k, so light isnt good until later...
But the jar shouldnt be completely airtight correct? there should be some airflow?Although I guess the lid is on upside down so it isnt fully airtight. havent had any luck yet, i think its mostly to do with my pressure cooking/boiling technique or lack of. i have tried about 6-8 jars so far and had no success, just a whispy white, with greenish mold in it
i read about contaminants and says that its over moisture, but i dont think so.anyways, so what about the jarlid? mycelium needs Oxygen, but how much? shouldnt there be enough in the jar already for it to get started?
