Choosing Mushroom Bags

mushrooms bags

Mushroom bags are a great way to make the process of growing mushrooms simple and convenient. They’re easy to cut holes in for air exchange, and they come in all shapes and sizes.

There are different kinds of mushroom bags on the market, and choosing the right one depends on three variables: filter size, bag size, and thickness. The thicker the bag, the more resistant it is to breakage.

Most growers choose to use breathable polypropylene bags with filters for their spawn production. They can be purchased with or without a sterile barrier, and many different filter types are available for commercial use.

Growing Mushrooms Made Easy: The Benefits of Using Mushroom Bags

Filter size varies from 0.2mm to 5mm in diameter. The larger the pore size, the more air can pass through. This is important for the growth of healthy mycelium and ensures that the substrate is free of contaminants.

Thickness varies between 2.2mm to 4.0mm, with thicker bags being more expensive. Depending on how often they’re used, growers may want to consider using stronger bags.

Heat resistance varies between 125F and 250F. This is important for a variety of applications including pasteurising and growing.

Inoculation & Sterilization

Most mushroom cultivation bags are autoclavable, meaning they can be sterilized in an autoclave where temperatures reach up to 250F (121C). This allows growers to add their substrate and then heat sterilize it. This saves growers time, money, and effort by allowing them to pasteurise their substrate in a single step.
