Orchid Chunky Mix is designed to be extra light and avoid compaction to provide maximum oxygen to the root system, a must for these unique plants. Well-suited for a wide range of orchid species. This includes Phalaenopsis (most commonly found in any store), Cymbidiums, Dendrobiums, Catacetum, Oncidiums, Paphiopedilums (Lady Slipper), Masdevallia, Cycnoches, Epidendrum, etc. **Some Jewel Orchids or really young orchids would be better suited for the Houseplant Chunky Mix as the root systems are just so much more fine than a traditonal orchid species. | Sol Soils Pumice Premium Potting Mix | Size 2 qt
