Hardwood Mushroom Substrate - Oak Sawdust/Wheat Bran - Fully Sterilized

Why This Hardwood Mushroom Substrate Supports Strong Mushroom Growth

A special formula combining oak sawdust, straw, wheat bran, and some lime has produced excellent growth results in many hardwood-loving mushroom strains. This hardwood mushroom substrate comes fully sterilized and ready for inoculation, helping reduce contamination risk and save preparation time.

Please note that once the substrate is inoculated, you will need to wait several weeks, depending on the mushroom spawn, for full colonization. After full colonization, the mushroom block can be fruited. This is all explained in the instructions provided.

1.6 Kg - This bag is the minimum to properly fruit a mushroom strain, but it may be too small to give enough yield to be able to make enough food.

This product is a fully sterilized mushroom substrate, which can accommodate a number of mushroom species to be able to see the growing process of various mushroom strains.

Ideally the product should be used immediately after delivery, otherwise keep it stored in the fridge at 4° Celsius for a maximum of 2 weeks and it will still be viable. It is good for both grain-to-grain inoculation and liquid culture inoculation. Instructions will be provided within the package. Once the bag is opened, the sterilization is compromised and so inoculation must be made immediately. Preferably open in front of a flow hood to avoid contamination.


PLEASE NOTE THAT THIS PACKAGE DOES NOT INCLUDE ANY MUSHROOM STRAINS. WE CAN PROVIDE MANY MUSHROOM STRAINS AND SPAWN.

Fully Sterilized and Ready to Use

This hardwood mushroom substrate is designed for growers who need a clean, reliable base for cultivation. Made from oak sawdust and wheat bran, it is fully sterilized and ready for inoculation right out of the package. That means less preparation time, lower contamination risk, and a smoother growing process. The substrate arrives in a form that supports immediate use, making it a smart choice for both commercial growers and home growers. With a balanced nutrient profile and a stable hardwood foundation, it provides the consistency mushrooms need to colonize efficiently and develop strong, healthy fruiting bodies.

Oak Sawdust and Wheat Bran for Balanced Nutrition

The blend of oak sawdust and wheat bran gives this substrate an ideal mix of structure and nutrition. Oak sawdust offers the dense hardwood fibers preferred by many gourmet mushroom varieties, while wheat bran adds extra nutrients to support faster mycelium growth. This combination helps create a productive growing environment without sacrificing quality or stability. Because the base is a true hardwood mushroom substrate, it works especially well for species that thrive on hardwood materials. Growers can rely on its texture, moisture retention, and nutrient balance to encourage strong colonization and healthy yields across a range of cultivation setups.

Consistent Performance for Serious Growers

Consistency matters in mushroom production, and this substrate is built to deliver reliable results batch after batch. Each bag is prepared to maintain uniform quality, which helps reduce variation from one grow to the next. The sterilized format supports clean inoculation and gives mycelium a strong head start in the growth cycle. Whether used for small-scale testing or larger production runs, this hardwood mushroom substrate is made to perform with minimal hassle. Its ready-to-inoculate design saves time and simplifies workflow, while the oak-based formula offers the dependable performance growers expect from a professional-grade substrate. It is a practical option for efficient, high-quality mushroom cultivation.
