Unicorn 3B bags are made for mushroom growing, and are a popular choice for those wanting to make 5-6lb mushroom fruiting blocks.

Fill with your desired substrate such as supplemented sawdust, fold the top of the bag down, and sterilize in an autoclave or pressure canner at 15psi.

Made of polypropylene, these mushroom growing bags can withstand this extreme heat.  However, be sure follow the equipment manufacturer directions.  A couple of our customers have melted their bags by not using the necessary amount of water in a pressure cooker.

After sterilizing substrate, let cool then inoculate with a mushroom culture in your sterile lab or “still air box” and seal.  Bags can be sealed with an impulse heat sealer, bag clamps, or zap strap.  The 5.0 micron “B” filter provides for adequate air exchange while keeping out mold spores and any contaminants larger than 5.0 micron.
