This Polypropylene Plastic Container is produced by Sac02, a Belgian company who is one of the world leader in filtered growing containers. This container is specifically designed for mycology, and allows optimal gas exchange for colonizing/incubating/spawning mushroom mycelium.
This container is also fully autoclavable, meaning it can withstand several cycles in a pressure cooker without warping or deforming (up to 7 cycles). The 0.2 micron filter strip in the jar lid is thicker than a standard 0.2um filter, and this thicker design has been patented by Sac02.
This container will effectively prevent contamination, and provide optimal gas exchange, which results in exceptionally fast colonization/incubation.
This container can also be used for fruiting by simply removing the lid and fanning daily, and replacing the lid lightly on top, not sealed.
