30 Pack Mushroom Grow Bags with 0.2 Micron Filter Patch, 8 x 5 x 20 Inch

• 【30% Thicker for Superior Strength】Made from 0.08mm autoclavable polypropylene, Gymgit mushroom grow bags are 30% thicker than standard 0.06mm bags. Built to withstand high-temperature sterilization, they resist micro-tears, punctures, and leaks, helping reduce contamination risks while providing greater durability during filling, handling, and transport.
• 【Stable Self-Standing Design】Featuring an expandable gusseted base, Gymgit grow bags stand upright once filled for easier handling, filling, and inoculation. The reinforced heat-sealed bottom provides added strength to support substrate weight and withstand sterilization cycles with confidence.
• 【Built for High-Temperature Sterilization】Crafted from premium food-grade polypropylene, these grow bags are autoclavable up to 250°F (121°C) at 15 PSI for 90–120 minutes. Engineered to resist warping and maintain seal integrity during sterilization, they're compatible with both household pressure cookers and commercial autoclaves for reliable, repeatable results.
• 【Premium 0.2 Micron Filter Patch】Unlike common 0.5-micron filter bags, Gymgit's 0.2-micron filter offers finer filtration to help reduce contamination risks while maintaining excellent airflow for healthy CO₂ outgassing and O₂ exchange. Designed to support strong, consistent mycelium colonization.
• 【Perfect for Home & Commercial Growing】Large 8" × 5" × 20" grow bags hold 4.4–5.5 lbs (2–2.5 kg) of substrate, making them ideal for fruiting blocks and cultivating oyster, shiitake, lion's mane, king oyster, and more. A great choice for beginners, hobbyists, schools, mushroom farms, and professional growers.
