We sell professional-grade Unicorn and Sac O2 mushroom grow bags to ensure reliable, high-yield mushroom cultivation. These bags are crafted from high-quality, autoclavable polypropylene, making them capable of withstanding high heat and pressure. This makes them ideal for use in pressure cookers and autoclaves during sterilization. Each bag features a micron-rated filter patch designed to allow optimal gas exchange while reducing the risk of contamination during the spawn or substrate colonization process.
Both Unicorn and Sac O2 bags come with a side-gusseted design, allowing them to stand upright when filled. They also feature durable bottom seals that can withstand movement and agitation during incubation. This practical design makes them suitable for commercial and at-home growers alike.
