AC Infinity | SUNCORE A1 | Seedling Heat Mat, IP- 67 Waterproof, 3" x 20"

A narrow 3 x 20 in heat mat for a single row of seed cells, a windowsill tray or a small propagator. It draws 6.5 W and warms the root zone to 80-87°F, up to 20°F above room temperature.

Heat comes from a far-infrared film rather than wire coils, which spreads it more evenly. The multilayer PVC is IP-67 rated with sealed seams, including the 60 in cord, and wipes clean. It is UL (E518635) and MET (E115128) certified, runs on 100-125V, and comes with a nylon drawstring bag.

Tip: a humidity dome over the seeds holds the warmth and moisture in; take seedlings off the heat once most have sprouted.
