Capillary mat is a fabric or felt material used to provide consistent, passive water delivery to plants by drawing water up through the growing medium via capillary action. The mat is placed under pots or seed trays, and water is supplied to the mat, allowing plants to absorb moisture from below as needed. This method helps ensure uniform moisture distribution and reduces the need for manual watering. Capillary mats are commonly used in greenhouses and nurseries for efficient plant care.
