Sterile Manure Mushroom Substrate

Larger fruits, larger yields.

Manure based substrates have been shown to produce larger and much healthier mushrooms. Easily the best substrate for dung loving species!

Ready to use

We’ve done all the hard work, simply open up and mix with your spawn. Can be stored in the freezer for up to 6 months.

How much do I need?
