All products are impulse and vacuum sealed when necessary to prevent contamination during transit. I have three types of substrate listings, below is a guide explaining the differences between them, choose which is best suited for you, or ask me for advice. Raw unsterile - choose this option if you want to sterilize or pasteurize the substrate yourself. Pasteurized - this is my preferred method because it kills most harmful bacteria while leaving useful and nutritious microbes for the mushrooms to consume.

Sterilize - kills most, if not all potentially harmful bacteria, but can also kill useful and nutritious microbes, that mushrooms need to grow. This item is made of coco coir, vermiculite, gypsum, water and oyster shell flour.
