Synthetic Jar Lid Filters
Synthetic Jar Lid Filters can be placed on top of a jar with ¼” holes to allow for maximum airflow in inoculated grain without compromising the environment. These are a great option for mycologist’s larger grain or spawn batches, as well as mycelium that thrive in higher oxygen environments or require a longer period of incubation.
