Ready to use: Shaped to fit a 75cm wall hayrack planter, these preformed coco liners just drop straight into place and can be planted up immediately Retain moisture: The coco fibres are naturally moisture absorbent and will release water slowly to the plant as needed. At the same time, they will release excess water to prevent waterlogging Help with aeration: The fibres are woven with plenty of air pockets that allow the free movement of oxygen to the roots Create healthy growing conditions: Naturally having a pH of 6, the fibres have anti fungal properties which prevent soil borne diseases Durable and tough: The fibres are tough and can resist tearing, providing support for plants, as well as a degree of insulation Dimensions: This liner measures 75cm (30 inches) by 15cm
