It’s hard to know how much salt was added then. 1g per liter is recommended. You added a lot more mushrooms to one bucket.

I spoke to a mushroom grower in the Facebook JADAM group and he told me mushroom spores from the leaf mold soil will survive in the JMS you apply to the soil and/or compost. My compost was a diverse range of materials but mostly shredded cardboard and rotted yard waste  

I added mushrooms after, so let's say when the bucket got full. I would say a month after on both of those. I picked some wild mushrooms and threw them in the bucket. It was mostly fruits, a lot of watermelons; nothing cooked, raw, cheese just simple fruits and vegetable. The amount of salt was sprinkle every time , the fruit was added. The bran was already made prior with EM1. what material did you use for your gunnysack compost?  

Also, did those visible mushrooms grow there? Or did you place them there, and not in the other bucket?  

Did you make this bokashi with food waste? Did the food waste already have salt on it? How much salt did you add?

In JADAM it is not recommended to add sea salt to food waste fertilizer because it already has salt.

But when I poured JMS on my gunnysack compost, I had mushrooms growing out of the bags and inside the bags.
