AC Infinity SUNCORE H3 Seedling Heat Mat with Digital Heat Controller | IP67 Waterproof | 10" x 20.75"

Give your seeds, clones, and young plants the perfect start with the AC Infinity SUNCORE H3 Seedling Heat Mat. Designed for professional growers and hobbyists alike, this premium propagation heat mat uses advanced far-infrared heating technology and a precision digital controller to create the ideal root zone temperature for faster, healthier germination.

Unlike standard heat mats that simply switch on and off, the SUNCORE H3 includes a digital temperature controller that displays the mat's current temperature in real time and allows you to set an exact target temperature. This eliminates guesswork, helping maintain consistent warmth without overheating delicate seedlings or propagation trays.

Ideal for seed starting, cloning, propagation, hydroponics, and indoor gardening, the SUNCORE H3 raises root zone temperatures by up to 11°C (20°F) above ambient while evenly distributing heat across the entire surface. The durable IP67 waterproof construction makes it easy to clean and suitable for humid grow room environments.
