cancel Sold out
Approximately 5L of Collectors Blend Orchiata Bark Power+ 12–18mm, a premium-grade substrate crafted from aged Pinus radiata bark, provides superior drainage and airflow for optimal orchid health. The coarse 12–18mm particle size is ideal for mature orchids like Cymbidium and Dendrobium, encouraging strong root systems and long-lasting media performance. Naturally processed and pathogen-free, this large-chip bark is the preferred choice for growers demanding structure, stability, and outstanding results.
Why Orchiata?
Produced in New Zealand, Orchiata undergoes a rigorous 10-step process that includes aging, calcium/magnesium buffering, and laboratory testing to ensure exceptional consistency, cleanliness, and root-readiness. Learn more about the process here.
Note: You may notice natural fungal speckling on the bark surface — this is normal and harmless. For details, see Fungal Appearances on Orchiata.
