The details
These
high-quality injection port grow bags
are designed for reliable, contamination-resistant mushroom cultivation. Made from durable 3.0 mil polypropylene, each bag features a built-in self-healing injection port for sterile inoculation with liquid culture or spores—no need to open the bag during inoculation.
The
side-gusseted design
expands into a sturdy, stand-up bag once filled, while the reinforced bottom seal is built to withstand mixing and agitation. A
Type T breathable filter
with a 0.2-micron pore size allows for optimal gas exchange while protecting your culture from contaminants throughout colonization.
Manufactured using proprietary materials and custom-designed equipment, these bags remain pliable at all temperatures and retain their strength even after sterilization. The wide opening makes sealing quick and easy, making them ideal for grain spawn, supplemented substrates, and other sterile growing applications.
