Tray SSF3

Fine substrate for high-density tray seeding, with Baltic peat and extra-fine wood fiber.

Tray SSF3 is the Arber professional substrate for seeding in plug trays, produced in Germany. It combines Baltic blonde peat 0–5 mm and German black peat 0–5 mm with extra-fine wood fiber: fine structure, medium-high dry bulk density, and a calibrated profile for high-density plug trays.

Features

Tray SSF3 solves the problem of mechanical filling: the dry bulk density of 281 g/L and the granulometry (particle size) 0–5 mm ensure full cells with no air pockets. This is a critical factor for automated high-density plug tray lines (240–400 holes). The fine structure combines Baltic blonde peat 0–5 mm and German black peat 0–5 mm with a small fraction of extra-fine wood fiber. This supports uniform contact between the substrate and the seed in each cell.

The PG Mix starter fertiliser supports the first stage of germination. The wetting agent allows you to re-wet the seeding root zone evenly after drying cycles. The substrate uses selected peat from the Baltic countries and Germany, consistently from the same fields, to guarantee quality continuity from batch to batch.

Why choose it

  • Fine granulometry (particle size) 0–5 mm: uniform seed contact and even coverage.
  • Integrated extra-fine wood fiber: lightens the mix without breaking down the structure.
  • pH 5.2–6 and EC 0.6–1 mS/cm: stable acid profile for professional seedling production.
  • Dry bulk density 281 g/L: stable load-bearing capacity for stacked trays, without collapse.
  • PG Mix starter fertiliser and root biostimulant: promotes seedling root development.
