At what point in the cultivation process do the mushrooms become safe® from outside contamination?  Is it after I start to see pins?

Welcome DC! It is in my opinion and observation that mushrooms are never safe from outside contamination unless they are in a sterile environment the whole time without any competition. Although fully colonized mycelium is more resistant to contamination than uncolonized substrate. I am not sure when any organism is safe from contamination. But here is a good place to to seek some more guidance on the subject. Hope it helps

Mushroom spores are another contaminant. They are just the ones we want to win and eat the food we put in their cage.


If they eat all the food, other airborne contams will have a hard time getting established.


Fully colonized cakes or bulk is most resistant, every time you expand by adding more casing, you take a chance of introducing another competitor.


Taking it to fruiting you have to consider the air in your grow chamber and the water you keep the humidity up with. I've had quite a few that pinned, even grew a couple fruits, then turned south.


Keep trying. Each area has its own idiosyncrasies. I had water one place that was 8.5 pH. That caused me some grief.
