Mushroom Grow Bags Autoclavable With Filter Patch 20cm x 12cm x 50cm

Mushroom Grow Bags – Autoclavable with 0.2 Micron Filter Patch (200mm × 120mm × 500mm)

These high-quality autoclavable mushroom grow bags are designed for reliable grain spawn and substrate cultivation. Made from durable polypropylene (PP) film, they withstand high-temperature sterilisation without warping or melting, ensuring a clean, contamination-free growing environment.

Each bag includes a 0.2-micron filter patch, allowing optimal gas exchange while blocking harmful contaminants such as mould spores, bacteria, and dust. The result is faster colonisation, stronger mycelial growth, and consistently higher success rates.

With a generous size of 20 × 12 × 50 cm, these bags provide ample space for bulk substrate or large grain batches. The 2.4 mil (0.06 mm) film thickness offers toughness and puncture resistance while remaining flexible and easy to seal with an impulse sealer.
