EDIBILITY

This Black Reishi is considered edible and medicinal, but it's very tough, woody, and bitter, so it's typically used in teas, powders, or tinctures rather than eaten like a culinary mushroom, requiring significant preparation like pressure cooking and blending to soften it. 

HOW MUCH SPAWN TO BUY

The weight of your mushroom spawn ordered determines its intended use, so:

300g - Used to inoculate a sterilized/pasteurized block of 1.5 Kg

500g - For larger sterilized/pasteurized substrate inoculations of up to 2.5 Kg.
