Rey Grain -1000 GR

Rye Grain - 1000 GR is widely used as a base for growing mushrooms. Thanks to its firm grain structure and natural nutritional profile, this grain is ideal for developing strong and uniform mycelium. The product is unprocessed and intended for those who prefer to maintain control over their own cultivation process.

Rye grain is often chosen as a substrate because the mycelium can develop evenly and steadily throughout it.

What is rye grain?

Rye grain is a type of grain that is naturally rich in carbohydrates and fibre. In mushroom cultivation, it is mainly used as a spawn substrate: a growth medium on which mycelium can grow before being transferred to a larger substrate.

This variety is 100% natural and contains no additives or treatments. This makes it suitable for growers who want to work as naturally as possible.

Why do growers choose rye grain?

Many experienced growers use rye grain because of the balance between texture and nutritional value. The grains remain well separated after sterilisation, allowing the mycelium to spread rapidly.

• Solid grain structure
• Good moisture absorption
• Suitable for various mushroom species
• Easy to combine with other substrates

How do you use rye grain as a substrate?

Rye grain is usually used in the preparatory phase of the cultivation process. It requires some attention, but offers a great deal of control over the quality of your crop.

1. Soak the grain in water to hydrate it.
2. Boil or steam it briefly so that the moisture is absorbed properly.
3. Sterilise the grain (for example, using a pressure cooker).
4. Allow it to cool, then inoculate it with mycelium.

Always work as cleanly as possible to prevent contamination. Many growers use rye grain as a starting point before transferring the mycelium to bulk substrates.

What can you expect?

When used correctly, many users experience uniform colonisation of the grain. The speed and quality of growth depend on factors such as hygiene, temperature and the mycelium culture used. Results may vary from person to person and depending on the situation.
