Dung Loving Mushroom Grow Bags

Grow dung loving mushrooms like never before in our high-quality mushroom grow bags. 

We've perfected the perfect formula for consistent results - we hand-pack every bag to ensure the grain spawn and compost don't mix, and seal it before sterilization to ensure no contamination risks at all. 

Discover High-Quality, All-In-One Mushroom Grow Bags

✔ A Superior Result - We use temperature probes to monitor core bag temperature during sterilization to verify that we reach the correct time/temperature targets.
✔ Consistency Everytime - We ensure the grain and substrate are separated to facilitate easy monitoring and faster colonization. This is unlike many large suppliers, who mix the grain and substrate to create a homogeneous mixture.
✔ Sealed Before Sterilizing - Through our proprietary process, we seal the bags before sterilization to ensure no contamination. Shelf-stable food products are made the same way, which guarantees product integrity.
✔ Meticulous Attention To Detail - We hand-fill every bag, carefully packing the ingredients and neatly folding the bag to prevent premature mixing. We place these in a perfect-size box and protective liner bag for further protection.
✔ Highest Quality Ingredients - We source local organic ingredients from USA businesses and prepare them in-house to ensure consistency in every batch.

FAQs

What is the difference between our mushroom grow bags and kits?

The difference between the two is simply the size; the all-in-one grow bags are ideal for beginners as they come with everything you need to see superior results. The kits, which come with four bags, are ideal for more experienced mushroom growers who might be growing multiple strains at the same time. 

How do we prepare our mushroom grow bags?

We meticulously hand-pack every bag using the highest-quality grain spawn and substrate to ensure the two are separated within the bag. 

Once packed, we carefully seal the bags to maintain a controlled environment. They are then subjected to a thorough sterilization process to eliminate potential contaminants and create the best environment for mushrooms to grow.
