Description Build a capillary watering setup for seed trays or houseplant pots with this 4-foot-wide mat, sold by the linear foot. The absorbent material helps distribute moisture under your plants and can be cut to fit your tray or growing area. How much mat do you need? The mat is 4 feet wide. One linear foot covers 4 square feet before trimming. For example, covering a 4-foot by 8-foot area requires 8 linear feet of mat. Contact us before ordering if you need a particular cut arrangement. How to build your capillary-mat setup Place plastic sheeting underneath the mat and a top cover or perforated foil above it. Cut the layers to fit your growing area. The mat can also be used in trays under houseplant pots or in seed-starting trays to help keep moisture more even. You can supply water manually, use a Surface Blumat, or place a preset Blumat in one of the pots on the mat. Material and specifications Width: 4 feet; sold by the linear foot. Thickness: 1.0 mm. Capillary lift: 8.0 cm. Lightweight, high-strength polypropylene, polyester and viscose material. Resists rotting, shrinking, chemical decomposition and crushing. Reversible; will not fray after cutting. Highly absorbent, allowing water to wick toward roots. Can I cut the mat to fit a smaller tray? Yes. The mat can be cut to size and will not fray at the cut edges. Do I need a Blumat sensor? No. You can supply water manually. A Surface Blumat or a preset Blumat in one of the pots provides another way to supply water to the mat.
