Broad mat material for shelf watering

This two-pack of automatic plant watering mats gives greenhouse shelves, indoor plant tables, and seed-starting trays a large capillary surface. Each mat measures 47.2 by 39.4 inches, which gives a gardener room to plan a broad watering zone.

The 3 mm material can be trimmed for shelf sections, tray bases, and plant groups. A cut piece belongs inside a protected tray or lined area where water stays contained.

How the mat helps

Capillary mat material spreads moisture under pots and tray pieces. It works well when pot bottoms touch the mat and the water source is easy to check.

The two-mat pack suits a greenhouse bench, a seedling shelf, or a group of indoor plants that share a watering station.
