I'm on this forum since long time ago, never registered, but i ned help ..
I've make a monotub, and make substrat with coco coir and vermiculite.
My cake was BRF tek, when fully colonized, i put it in my substrat.
So wait about 1 month, the mycelium was white, and smell very good !
When it was time to harvest the first mushroom, i found some problems .. (I think ?)
As you can see, there is yellow/orange mark.
So i taken the first harvest, here is the second, and yellow continue to be. And substrat look so strange. But, no smell problem..
