Product Details

Insect Frass can be used as an additive to Liquid Cultures, Agar Petri Dishes, and Spawn mediums to promote vigorous, aggresive mycelial growth of "dung-loving" mushroom species.

Insect Frass provides a plethora of nutrients, minerals, and microogranisms which aid the health of mycelial cultures. Pacific Northwest Mycology adds insect frass to our in-house Liquid Cultures, Agar Petri dishes, and spawn medium, with excellent results.
