Small mushroom grow bag. 4" X 3" X 18" makes these mushroom grow bags perfect for running the spawn of your choice. These bags are autoclavable and used for spawn incubation. Our small mushroom grow bags have a microporus filter patch that allows proper gas exchange but will not allow contaminants into the grow bag. These bags use a .05 micron filter patch so you can seal the bags before sterilization. This side-gusseted bag gives a sturdy stand-up bag after filling and a strong bottom seal. We manufacture it with equipment we designed and with proprietary additives, Our bags are pliable at any temperature as well as after sterilization. The bag opening is designed for easy sealing and the bag's bottom seal can withstand agitation.
