Orchid Bark Orchiata Power 35L | 9–12mm

Give your plants an ideal root environment with Orchiata Power, a standalone growing medium crafted from 100% renewable New Zealand Pinus radiata bark. Produced using a proprietary natural aging process rather than composting, Orchiata retains a hard physical structure that will not break down or compact over time.

The Power grade features a medium 9–12mm chip size, providing an optimal balance of aeration, water retention, and nutrient absorption. It is a choice for mature orchids undergoing their second potting, as well as chunky potting mixes for aroids, hoyas, and bromeliads. Available from suppliers such as Sage Horticultural, Dr Greenthumbs, or Richos 4 Hydro.
