TonGass 60-Pack Large 8x5x20 Autoclavable Mushroom Grow Bags with 0.2 Micron Filter Patches – Durable Substrate Bags

Overview

TonGass offers a 60-pack of large mushroom grow bags designed to support clean, efficient cultivation workflows. Each bag measures 8 inches by 5 inches by 20 inches, providing ample interior space while staying compact on standard shelving. The film is thick and robust, built to withstand autoclave sterilization and repeated use when paired with proper care. A microporous 0.2 micron patch enables essential gas exchange while helping to keep contaminants out, creating a controlled environment for your substrate.

Key benefits

• Autoclavable design ensures reliable sterilization of substrate and mix.
• Generous 8x5x20" dimensions maximize workspace efficiency without crowding racks.
• Durable 6mm film provides tear resistance during filling, handling, and transport.
• 0.2 micron filter patches support air flow while acting as a barrier to particulates.
• Value-pack of 60 bags helps you equip larger or ongoing cultivation projects.

Real-world use cases

These bags suit hobby growers, small cultivators, or suppliers preparing spawn runs. The sturdy material feels substantial in the hand, and the filter patches are clearly visible against the bag’s clear surface, signaling readiness for gas exchange. Use them to fill substrate, sterilize in batches, and store inoculated or colonized material. The 8x5x20" footprint helps you organize multiple runs on a single rack, reducing clutter and supporting a steady workflow.

Care and considerations

• Follow standard sterilization protocols and allow bags to cool before handling.
• Inspect patches and seams for damage prior to use.
• Label batches clearly and store in a clean, dry area away from direct heat or sunlight.
