Mushroom substrate 15kg coconut perlite gypsum

  
15kg coco substrate + perlite + gypsum for mushroom cultivation. The substrate is sterilized by us at 127 c for 2 hours to ensure its sterility. The coco / perlite substrate is non-nutritious which gives it an important resistance to external contamination. On the other hand, the texture is airy, which allows the mushrooms to grow quietly without worries.
