Grow Gourmet Mushrooms at Home – Medium Mushroom Grow Bags (with Free Shipping!)
Start your mushroom growing journey with these premium-quality medium mushroom grow bags, trusted by commercial cultivators and home growers alike.
Constructed from 0.08mm polypropylene—30% thicker than the standard 0.06mm used by many competitors—these bags offer superior tensile strength and heat resistance. Fully compatible with autoclaves and pressure cookers, they withstand the sterilisation cycle without compromising structural integrity, making them ideal for high-performance substrate preparation.
Each bag includes a 0.2-micron filter patch (38mm x 38mm) to ensure clean airflow while keeping out contaminants—supporting strong, healthy mycelium growth.
✅ Bag dimensions: 200mm x 120mm x 500mm (slightly larger than the Unicorn 3T for more substrate volume)
✅ Reliable filtration: 0.2μm filter patch for optimal gas exchange
✅ High-temperature resistant: Suitable for autoclaving and pressure sterilisation
✅ Available in clear and black: Black bags are preferred by growers to reduce side pinning and encourage mushrooms to fruit at the top
✅ Versatile pack sizes: Choose from 10, 20, 50, or 100 bags
✅ FREE untracked shipping Australia-wide on 10 and 20 packs!
✅ FREE tracked shipping Australia-wide on 50 and 100 packs!
Perfect for growing oyster, lion’s mane, shiitake, and other gourmet mushrooms. Ideal for hobbyists, educators, and commercial growers looking for professional-grade results.
Choose from either clear or black grow bags—black is our favourite as it is especially effective in reducing side pinning though can be more challenging to check for containments. Hint, run a clear bag in each batch for checking production quality. Smelling the blocks when opening for fruiting is another good indicator of any issues
Let customers speak for us
I live in WA, and placed a large order of both turmeric and ginger as we can’t get anything organic here in WA! let me tell you ! This is OUTSTANDING quality Ginger and Turmeric! It arrived within 3 days in perfect condition as the owners took every effort to prepare the produce properly before packaging and shipping.
