Kapmat is a capillary matting that is perfect for your Greenhouse Pot Benches or in your home garden, where a water irrigation pad is required. This is especially useful for water sensitive plants where plants may need to absorb water from below rather than be watered from above (Example: African Violets). This is an environmentally friendly product that soaks up excess water, while keeping plants moist. Kapmat can easily be cut to any shape or size to fit any pot bench or display. It is a lightweight polyester felt and is approximately 3/16" (4.6mm) thick.
