Grow Gourmet Mushrooms at Home – Large Mushroom Grow Bags (with Free Shipping!)
Start your mushroom growing journey with these premium-quality large 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 (45mm x 80mm) to ensure clean airflow while keeping out contaminants—supporting strong, healthy mycelium growth.
✅ Bag dimensions: 250mm x 140mm x 560mm (slightly larger than the Unicorn XLS for more substrate volume). 5KG recommended maximum weight with substrate and spawn.
✅ 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, 25, 50, or 100 bags
✅ FREE untracked shipping Australia-wide on 10 packs!
✅ FREE tracked shipping Australia-wide on 25, 50 and 100 packs!

Packaged with care, really impressed with the freshness and quality. Thanks
Mushrooms, ginger and turmeric are top quality. Fantastic, quick service and very helpful with any questions I had 🙏💖
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. Never have I been so happy and I’ll continue to support them! Their commitment to deliver not only quality produce but quality service is not often seen anymore these days Thank you guys , 🧡

Beautiful fresh ginger, great quality
Three weeks ago I received the kit and have just had my first harvest. The process was very easy and I loved watching the mushrooms grow daily.
This is my first experience of eating Lion’s Mane mushrooms and have been pleasantly surprised at how delicious they are.
