Mushroom Grow Bags Autoclavable With Filter Patch 25cm × 14cm × 50cm

Mushroom Grow Bags – Autoclavable with 0.2 Micron Filter Patch (250mm × 140mm × 500mm)

These premium autoclavable mushroom grow bags are built for dependable grain spawn and substrate cultivation. Made from robust polypropylene (PP) film, they endure high-temperature sterilisation without deforming, ensuring a sterile, contamination-free environment for vigorous mycelial growth.

Each bag includes a 0.2-micron filter patch, which provides excellent gas exchange while preventing contaminants such as mould spores, bacteria, and dust from entering. This promotes faster colonisation, stronger growth, and more consistent results.

With a spacious size of 25 × 14 × 50 cm, these bags offer extra volume for bulk substrate loads, large grain batches, and commercial-scale projects. The thicker 3.2 mil (0.08 mm) film delivers superior durability and puncture resistance while still remaining flexible and easy to seal with an impulse sealer.

Features:

• Made from autoclavable PP film

• 0.2 µm filter patch for safe, efficient gas exchange

• Ideal for grain spawn, bulk substrate, and liquid culture transfers

• High clarity for easy monitoring of colonisation

• Extra-durable 3.2 mil thickness

• Compatible with pressure cookers and autoclaves

• Large 25 × 14 × 50 cm capacity for hobbyists and commercial growers
