Every stage needs the right root environment. Our range follows the journey from sowing and rooting to propagation and growing on.

A compact starting size for the first growing stage. Choose a size to suit your sowing method, tray and next propagation step.

More room for root development after the plug stage. Match the block, planting hole and transplanting time to your crop.

Elongated formats for the next growing stage. Choose according to plant spacing, crop duration and your irrigation system.
Alongside plugs, blocks and slabs, we are developing new applications for grass fibres. From our smallest fractions to a potting mix suited to the plant.
Our smallest grass fractions take a new form: grass-fibre pellets. This also gives our fine material a place within the GramiGrow product family.
We are developing potting soil improved and optimised with grass fibres. We tailor the balance of ingredients to the plant and its use.

The substrate, irrigation and growing conditions work together. We will discuss how to test and monitor GramiGrow in your system.
Monitor moisture distribution, drainage and irrigation frequency.
Measure EC and pH and match your feeding programme to the crop.
Observe rooting, transplanting time and the transition between formats.
Include light, temperature and evaporation in your assessment.

We develop with growers, guided by practical experience. Choosing the right product starts with the crop and your way of working.
Sowing, cuttings and young plants: discuss your tray, transplanting time and root-space requirements.
Match the next step to your irrigation, plant spacing and crop duration. Sweet pepper is part of our growing trials.
Different crops need different approaches. We are gaining experience with crops including Phalaenopsis and lavender.
Start with the growing stage. A plug is a starting format; a block offers extra root space during propagation; a slab is a format for growing on. Discuss the combination for your crop with us.
A different growing medium may change moisture distribution and drainage. Start with a growing trial and monitor moisture, EC, pH and root development before setting your programme.
Tell us which crop you grow, how your system is set up and which size you need. Together we will discuss a suitable trial and current availability.
