Features

The prevalence of brown peat ensures mechanical cohesion during pressing. It also provides stable pH buffering and cation exchange capacity. Integrated dolomitic lime corrects the naturally acidic pH of peat to a range of 5.5–6.5. This range suits azaleas, camellias, blueberries, and other sensitive crops.

The PG Mix starter fertiliser supports the first growth phase. The wetting agent allows the plug to re-wet evenly after drying cycles. Press RK-W is developed for year-round use, with predictable behaviour batch after batch and across different seasonal conditions — fewer process adjustments for the grower.

Selected peat from the Baltic countries: consistently from the same fields, season after season, to guarantee quality continuity batch after batch.

Why choose it

  • Fine structure 0–7 mm: particle size suited to both containers and pressed plugs.
  • Predominant brown peat fraction: rich surface area for the early root zone.
  • pH 5.5–6.5 and EC 0.4–0.7 mS/cm: low salinity for professional seedling production all year round.
  • Density 270–280 g/L: full substrate body, cohesion suited to pressed plugs.
  • Base fertiliser + root biostimulant: fast rooting support from the start.
