Masters Mix Mushroom Substrate - 100% Australian Grown

Unlock the full potential of your mushroom cultivation with our Masters Mix, a premium blend of 100% Australian-grown hardwood and non GMO soy hull pellets. Designed for high-yield and rapid colonisation, this substrate is the same mix used by us in our farm for its superior performance.

Choose Your Ideal Mix:

✔ 70% Hardwood / 30% Soy Hulls – A well-balanced ratio optimised for strong mycelial growth and abundant fruiting whilst only requiring heat pasteurisation (add boiling water to mix) for use.

✔ 50% Hardwood / 50% Soy Hulls – A higher nutrient content for those seeking maximum supplementation and yield.  This mix does require either steam sterilisation, autoclave or pressure cooker for best results.

Available In Multiple Sizes:

• 1KG – Ideal for trials or hobby setups
• 2KG – Small batch growing
• 5KG & 10KG – Great for ongoing or commercial use

Both formulations come in easy-to-use, pelletised form, ensuring a dust-free mixing process and efficient hydration. Whether you’re using sterilisation or pasteurisation, Masters Mix provides consistent results and higher mushroom yields. 

Hint, for 2.5KG bags use 950g substrate with 1400mL water per bag.
