The XLS-B Unicorn bag is the largest mushroom fruiting bag in the Unicorn range. It’s ideal for the mycologist looking to make their own substrate. Plus, thanks to its large 5.0 micron filter, it’ll allow for more gas exchange than its XLS-A and XLS-T counterparts - which is perfect for faster growing strains.

To use this Unicorn bag, mix up your substrate and pour it inside (don’t forget to leave space for your spawn!) then fold the bag over and pop into your pressure cooker (at your own risk). Once sterilised, allow to cool and take out your substrate bag in a clean environment - open the top and pour your spawn in. From there, seal your bag and give it a mix.
