Masters Mix Mushroom Substrate Sawdust and Lupin hull Pellets (Non Soy based )

Our 3 kg pre-sterilized, ready-to-use Master Mix Mushroom Substrate is ideal for mushroom cultivation. Designed specifically for Wood-loving mushrooms, this substrate is hydrated to field capacity, ensuring optimal moisture content for mushroom growth. It is ideal for all woodloving mushroom species that like wood.

This substrate is a balanced blend of 50% hardwood sawdust and 50% Lupin pellets. Lupin pellets are rich in fermentable fiber and nitrogen, essential for boosting mushroom growth. However, as the mixture contains only half wood, the later stages of mushroom growth might not be as prolific as the initial burst. This mix is excellent for various mushrooms but is not the best choice for species like Shiitake and Turkey Tail, which thrive in environments with more wood. The Master’s Mix is famous in mushroom farms and starter kits because it helps achieve a quick and impressive first harvest. It is incredibly motivating for beginners in mushroom cultivation and offers a faster turnaround for mushroom farmers.

The Master’s Mix Mushroom Substrate also comes with Woodchips. When mycelium comes in contact with woodchips while growing, they become really Vigorous—resulting in thicker and faster colonisation. For more information about Mycelium, check out Our Grain Spawn.

If you are working with our Grain spawn and do not want to use up all the spawn in one go,  inoculated a grain bag with agar or inoculated a substrate bag with grain spawn for which you had to cut open the bag but have no way to seal the bag again consider to have our Large  Sealing Bag Clips.
