{"product_id":"ac-infinity-suncore-h3-heat-mat","title":"AC Infinity Suncore H3 Heat Mat","description":"\u003cp\u003eThe AC Infinity Suncore H3 Heat Mat is a 20 W far-infrared seedling heat mat supplied with its own inline digital heat controller, warming the root zone where germination speed and cutting strike are actually decided. Within AC Infinity's SUNCORE range the H designation is the distinction that matters: where the mat-only A-series runs flat out whenever it is plugged in, the H3's included controller holds an exact setpoint, powering the element only while the sensed temperature sits below it. Placed beneath a propagation cover such as the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-humidity-dome\" target=\"_blank\" title=\"AC Infinity Humidity Dome\" rel=\"noopener\"\u003eAC Infinity Humidity Dome\u003c\/a\u003e, its bottom warmth accelerates germination and drives humidity up quickly under the canopy.\u003c\/p\u003e\n\u003cp\u003eThe mat is a quad-layer PVC laminate just 2.48 mm (0.09 in) thick, heated by a far-infrared film lining rather than wire coils, so warmth spreads evenly across the full 25.4 x 52.7 cm (10 x 20.75 in) surface instead of concentrating into scorching lines. Sealed seams and a sealed cord connection earn the mat an IP67 rating, meaning watering spills wipe straight off, though it must never be immersed. AC Infinity rates the mat to lift the rooting area approximately 5 to 11 °C (10 to 20 °F) above ambient, settling into a steady 27 to 31 °C (80 to 87 °F) band in typical rooms. The controller sits inline on the 152.4 cm (60 in) cord in a compact 8.0 x 4.5 cm (3.14 x 1.77 in) body, with a backlit display showing sensed and set temperatures side by side, up and down buttons spanning a 0 to 50 °C (32 to 122 °F) range, a switchable °C or °F readout, and screw mounts for fixing it to a wall.\u003c\/p\u003e\n\u003cp\u003eThe mat matches the standard 1020 tray footprint and pairs almost exactly with the XL Humidity Dome tray at 54.5 x 28.4 cm. The box includes the mat, the inline controller, a water-resistant nylon storage cover with drawstring closure, two machine screws and two wood screws for wall mounting. Where a seed packet gives no figure, the manual suggests holding 18 to 24 °C (65 to 75 °F), and a crop temperature chart is printed on the mat face itself, while an independent reading at tray level from an \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-cloudcom-b-hygrometer\" target=\"_blank\" title=\"AC Infinity CLOUDCOM B Hygrometer\" rel=\"noopener\"\u003eAC Infinity CLOUDCOM B Hygrometer\u003c\/a\u003e confirms what seedlings are actually experiencing. AU-supplied units run on 240 V. The included controller cycles the mat thermostatically against its setpoint, holding a set root-zone temperature through cold nights without overheating a tray on warm afternoons.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e place the mat on a flat, well-drained surface free of standing water and sharp objects. Never position it inside a tray, cover it directly with soil or growing media, or lay heat-insulating materials over it, as trapped heat can build dangerously. The mat is rated IP67 for spills and wipe-downs but must not be immersed in water.\u003c\/em\u003e\u003c\/p\u003e","brand":"AC Infinity","offers":[{"title":"Default Title","offer_id":45953077313694,"sku":"819137024540","price":64.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/AC_Infinity_SUNCORE.png?v=1784690693","url":"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-suncore-h3-heat-mat","provider":"Hydro Oasis","version":"1.0","type":"link"}
