Your strawberry production is in good hands with us - From start to finish

The young plants grow in a special tray-plant substrate that encourages rapid rooting, uniform growth and plant development. For your rack cultivation, early crop, ongoing production and/or summer crop you can choose from a wide range of substrates to fit your own requirements.

The composition of our substrates is based on careful consideration of many criteria, such as:

• The workability of the substrate mixture
• Rooting speed once the tray plants have been planted
• Use of components such as perlite and coconut products
• Drainage properties
• Water and air content of the medium
• Cultivation method
• Fertilisation method during production
• Desired pH of the medium
• The yield produced by the substrate

Working with the criteria listed above we have developed a range of professional substrates that are proven in practice for many years.

Tref can also produce a specific substrate that is tailored to your requirements. All our substrates are RHP-certified.

The Tref group has total control over all its raw materials so we can be confident of their quality, so you can be certain of your production.
