Substrate designed for the cultivation of the main species of orchids such as Cattleya, Dendrobium, Cymbidium and Phalaenopsis. Orchids are plants that both require a well-ventilated substrate and fluid in the roots. For these reasons, the orchid tree is formed using pine bark, coconut and peat. These materials provide the characteristics of porous soil and optimal drainage for the growth of all kinds of orchids while allowing sufficient water and nutritional reserve for the plant.
