The SUNCORE S3 Seedling Heat Mat provides steady bottom heat to help create favorable conditions for seed germination and plant propagation. Its innovative far-infrared heating film warms quickly and distributes heat evenly across the mat.

Unlike traditional wire-coil heating elements, the far-infrared film produces softer, more evenly distributed warmth to help reduce the risk of concentrated hot spots around seeds and roots.

The included heating controller features an adjustable dial that allows you to regulate the heat output over time. Instead of simply switching the mat on and off, you can adjust the heat level to maintain a more consistent growing environment. The controller offers low, medium, and high settings for convenient adjustment.

The mat maintains a typical temperature range of 80–87°F (27–31°C) and can raise the rooting area by up to approximately 20°F above the surrounding ambient temperature, depending on environmental conditions.

Built for repeated use, the S3 features IP67-rated quad-layer PVC construction that is flexible, wear-resistant, and easy to wipe clean. The mat can be rolled up when not in use, making storage simple and convenient.

A water-resistant nylon drawstring bag is included for storage and transportation.

The SUNCORE S3 is well suited for seed starting, germination, propagation, cuttings, rooting, indoor gardening, and other applications where supplemental root-zone warmth is beneficial.
