Substrate designed for the cultivation of the main types of orchids such as Cattleya, Dendrobium, Cymbidium, and Phalaenopsis. Orchids are plants that simultaneously need a well-ventilated substrate and moisture at the roots. For these reasons, the orchid potting soil has been formulated using pine bark, coconut fibers, and peat. These materials provide the characteristics of porous soil and optimal drainage for the growth of all types of orchids, while allowing an adequate amount of water and nutritional reserve for the plant.
