Unicorn Mushroom Growing Bags

These are industry standard mushroom growing bags. They are made of a plastic that is durable enough to withstand sterilization conditions which makes them perfect for making mushroom spawn or substrate.

Simply fill the bag with the desired substrate, fold it over itself and sterilize it in a pressure cooker or atmospheric steam sterilizer (ex. bubbas barrel).

There are two filter patch options; 14A (0.5 micron) and 3T (0.2 micron).

The 14A filter patches are designed to allow more airflow and are typically used for bagging substrate.

The 3T filter patches are designed with much smaller pores for increased sterility. These are most often used for bagging grain spawn.
