Mushroom grow bags are an essential tool for cultivation, both for the professional cultivator and the enthusiastic hobbyist.

They can be used as spawn bags- in which the bags are used for sterilizing grain and propagating mushroom cultures- or, they can be used to create supplemented sawdust fruiting blocks for growing gourmet mushrooms.

If you’re growing mushrooms, you’ll want to be familiar with grow bags.

Why use mushroom grow bags?

However, grow bags offer certain features that are difficult to access otherwise:

Choosing the right mushroom to grow bag

Not all mushroom grow bags are exactly the same, but choosing the right bags for a given operation means paying attention to just three variables: filter size, bag size, and bag thickness.

Filter size

Filter sizes vary. That is, the size of the holes, or pores, in the filter varies, usually from 0.2 microns to 0.5 microns. The smaller the pore size, the less can get through. That means fewer spores and other contaminants, but it also means less air. The key is to strike workable a balance between the need for air and the need for protection. For most purposes, the filter should be no larger than 0.5 microns.

Bag size

There is no hard and fast rule about bag size. Bags that are too small are inefficient; bags that are too big are inconvenient—but what sizes are too big or too small varies from grower to grower. Points to consider include the size of the sterilizer and the size of the hoped-for crop. Above all, how big will a bag of a given size be when full?

A large bag, one that is 20 cm across and 46 cm tall, can hold about 2 kg of inoculated substrate.


The thicker the plastic, the stronger the bag – but the stronger bags are also more expensive. The normal range is between 2.2 mils to 4.0 mils. Growers can start off with bags at the thin and inexpensive end of the scale, and if the bags rip too often (a ripped bag is vulnerable to contamination), step up to something thicker. The occasional rip is not considered a problem, just part of the cost of doing business.
