Its funny that of 4 culutures of this fungus on coffee grounds, 2 have boomed, yet the other 2 are lagging behingd. Could it be variations in coffee brand? Moisture content? There are no contaminants visible.
Does it need perhaps some added vitamins in water?
I am enjoying this hobby but haven't grown a single mushroom so far!!!
