Black Peat
Arber black peat is a raw material with a high decomposition grade (H6–H8), extracted from deep deposits in German peatlands. It is available in two granulometries — 0–10 mm for seeding and plug trays, 0–20 mm for cultivation and rooting — and in two pH options: standard (natural) or pre-corrected to pH 5.5–6.5 with dolomitic calcareous pH corrector.
