Description
Buy Soya Hull pellets for bigger and better mushrooms.
Soya hull pellets (also known as soybean hull pellets) are a high-quality substrate supplement used in gourmet and medicinal mushroom cultivation. When combined with suitable base substrates such as hardwood sawdust or coco coir, soy hull pellets provide easily digestible carbohydrates that support vigorous mycelial growth and improved yields.
These pellets are supplied clean, dry, and consistent in size, making them ideal for controlled substrate preparation in mycology applications.
What Are Soya Hull Pellets?
Soya hull pellets are produced from the outer husk of soybeans after food processing. The hulls are dried and compressed into pellets for ease of storage, hydration, and accurate mixing.
In mushroom cultivation, soybean hull pellets are valued because they:
Provide fast-access energy for mycelium
Improve substrate performance when used in correct ratios
Break down evenly when hydrated
Are widely used in both small-scale and commercial grows
Why Use Soy Hull Pellets in Mycology?
Soy hull pellets are commonly used as a supplement, not a standalone substrate.
They are especially popular in:
Supplemented CVG-style bulk substrates
Hardwood + soy hull mixes (e.g. Master’s Mix–style substrates)
Gourmet and medicinal mushroom production
When used correctly, soy hull pellets can:
Improve colonisation speed
Increase fruiting consistency
Support larger and more uniform flushes
⚠️ Because soy hulls add nutrition, correct hygiene and preparation are essential.
Suitable Mushroom Species
Soya hull pellets are commonly used with wood-loving and supplemented-substrate species, including:
Oyster mushrooms
Lion’s Mane
Reishi
Turkey Tail
Other gourmet and medicinal varieties
They may also be used in lightly supplemented bulk mixes when contamination control is high and ratios are conservative.
How to Use Soya Hull Pellets
Soy hull pellets should be:
Fully hydrated before use
Evenly mixed with the base substrate
Used at controlled ratios
For lightly supplemented bulk substrates, small amounts may be hydrated using boiling water.
For higher supplementation levels, pressure sterilisation is strongly recommended.
Always combine with:
Fully colonised grain spawn
Clean tools and containers
Appropriate airflow and moisture control

Important Notes
Intended for mycology and cultivation use only
Not a complete substrate on its own
Increased nutrition means increased contamination risk if mishandled
For growers new to supplementation, we recommend starting with small ratios or choosing a pre-prepared substrate.
