AC Infinity SUNCORE H3 Seedling Heat Mat with Digital Controller

Precision Far-Infrared Heating Mat (10" × 20.75") for Seed Starting, Germination, and Rooting Propagation

The AC Infinity SUNCORE H3 (AC-SMH3) provides consistent, gentle root-zone warming to accelerate seed germination and cloning success inside a standard 10×20-inch tray footprint (10.0" × 20.75"). Engineered with advanced far-infrared heating film technology, the SUNCORE H3 distributes thermal energy evenly across the entire mat surface without hot spots or heating coil spikes that can scorch delicate roots or dry out media.

Equipped with an integrated digital heat controller, this heating mat allows growers to monitor real-time temperature readouts and dial in precise target levels, eliminating the guesswork that often leads to seed rot. Constructed from a durable, quad-layer IP-67 waterproof PVC housing, the SUNCORE H3 resists moisture, spills, and wear while easily rolling up for compact off-season storage.

Key Features & Benefits

• Far-Infrared Heating Film: Lined with innovative far-infrared heating elements that emit soft, uniform heat up to 20°F above ambient air temperature—preventing hotspots and root scorching.
