ANNOUNCEMENT! Ask us about a bio-degradable bag option. Unicorn is currently developing a solution to better serve the mushroom community.

What The Fungus has been the Canadian Distributor of Unicorn Bags since 2014. We proudly support and rely on Unicorn Bags for our mushroom business.

Please refer to the Unicorn Bag’s website for a complete list of bags that they manufacture. Be sure to order the proper bags: Polypropylene (PP) for high temperature autoclave or polyethylene (PE) for low temperature irradiation.

Available in 100 or case quantities of 1000 bags. We generally keep in stock 14A, 3T and XLS-A bags; however, we are happy to custom order anything that Unicorn Bags Manufactures.

14A is the standard bag used throughout the mushroom industry for wood-based substrates.

3B allows more air exchange for mushroom species that require more oxygen during the spawn run, and in some cases, to initiate pinning.

3T has a finer filter and is recommended for grain spawn use.

XLS-A a high yielding bag that can hold approximately 12-14 lbs of substrate
