Orchiata is aged New Zealand Pinus radiata (radiata pine) bark — processed through a natural aging method that modifies the outer chip surface while leaving the hard inner core intact, producing a stable, pathogen-free orchid substrate.
Pinus radiata was introduced to New Zealand in 1859 and grows faster and denser there than in its native California range, yielding thicker bark with harder, rounder chips that resist delamination and compaction. Orchiata's aging process — distinct from composting, which degrades the entire chip — is what allows the bark to outlast conventional fir bark by 2–3 times. Natural Dolomite is added during processing to pre-set pH; no other chemicals are used.
- Orchiata raw material: 100% Pinus radiata bark sourced from New Zealand plantation forest — no chemical treatment.
- Orchiata processing method: natural aging (not composting), which preserves chip core hardness for 5+ years in the pot.
- Orchiata pH range: 5.5–6.5, established by Dolomite added at end of processing.
- Orchiata EC: below 0.3 mS/cm — no salt accumulation, no flushing required.
- Orchiata chip sizes: five grades from Precision (1/8"–1/4") to Super (3/4"–1").
