Sterile substrate perfect for those manure loving mushrooms 

Our special manure mix consists of horse manure, Coco Coir, Vermiculite, Gypsum, Lime and Wheat Straw. We then sterilise the sealed substrate to get rid of any of the nasty stuff. This mushroom substrate is perfect for people who want to grow their own mushrooms at home using the monotub method. Please see our full guide here to help you in this process.

**Please use as soon as received for best results. However you can store in fridge for around 1-2 months and for longer you can store in freezer. Just remember to thaw at room temperature before use if storing this way.**
