A natural, fibrous material derived from the outer husk of coconuts, commonly used as a growing medium in cannabis cultivation. Known for its excellent water retention and aeration properties, coco coir provides an ideal environment for root growth and is often used as a substitute for soil. It is particularly popular in hydroponic and soilless growing systems, as it offers greater control over nutrient delivery while being an eco-friendly, renewable resource.
