Want to make your own fruiting blocks? Then you need mushroom grow bags!

We offer Unicorn 10A bags, which can be used to make 2-4lb blocks.

Made out of polypropylene, these bags can handle the extreme heat that comes with sterilization. They also feature a 0.5 micron filter that allows for adequate air exchange while keeping out contaminants.

You can make fruiting blocks with these bags without sterilization, but this only works with certain kinds of mushrooms and substrates. To learn how to make your own fruiting blocks without any expensive sterilization equipment, check out our Growing Mushrooms for Beginners course.


  • Material: 3.0 mil polypropylene
