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 pH corrector.
Discover → Loose raw material for custom mix formulation. Sphagnum blonde peat moss, block-cut from selected Baltic origins. Available in four granulometries (0–10, 10–40, 20–40, 0–40 mm) and two pH options: standard (3.5–4.5) or pre-corrected (5.5–6.5).

Arber expanded clay is an inert raw material produced by controlled thermal expansion. Available in 10 L Bag and 45 L Bag, you use it as a professional drainage layer, as a component in custom mixes for long-cycle plants, as a substrate for hydroculture, and as a decorative top-dressing for indoor pots.
Arber Perlite is a mineral raw material of volcanic origin, thermally expanded to a granulometry of 2–6 mm. It is a lightweight, draining, and chemically inert component. It improves the water profile of Pro substrates and supports the formulation of custom mixes in seedling production and nursery. Available in 100 L bags.
Arber Pumice is an inert raw material of natural Italian volcanic origin, sourced from a consolidated supply chain. Available in two granulometries — 3–8 mm in 50 L Bag and Big Bale, 3–5 mm in Big Bale — for custom mix formulation and integration into Pro substrates for medium- to long-cycle plants.
Arber Vermiculite is a thermally expanded mineral raw material, available in 0–2 mm and 0–4 mm granulometry (particle size). Its lamellar structure retains water and nutrients and releases them gradually to the plant. It is a preferred component in seeding mixes, cutting propagation, and seed covering in plug trays.
Arber volcanic Lapillus is an inert mineral raw material of natural Italian volcanic origin, sourced from a consolidated supply chain. Two granulometries — 3–5 mm and 5–10 mm in Big Bale — calibrated for different crop cycles: fast drainage and fine mulching for short cycles, stable structure for long cycles.
