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.

Recommended use

These injection port grow bags are recommended for sterile mushroom cultivation using grain spawn, supplemented substrates, or bulk media. Ideal for inoculation with liquid culture or spore syringes through the self-healing injection port, allowing sterile transfer without opening the bag.

Fill bags with your prepared substrate and/or grain, seal using an impulse sealer, and sterilize according to your standard protocol. Once cooled, inoculate through the injection port and allow the filter patch to provide proper gas exchange during colonization. The reinforced bottom seal and durable construction make these bags suitable for mixing, shaking, and agitation as needed.

Designed for use in laboratory, home, and commercial mushroom cultivation settings.
