Review: Nur zu empfehlen - Angaben können nur in Fahrenheit geregelt werden, ansonsten wird die Raumtemperatur über das Steuergerät ausgelesen, NICHT über die Heizmatte. Regelt aber korrekt bei mir und sehe darin eine Stromersparnis, da nicht durchgehend beheizt wird, sondern nur wenn die Raumtemperatur sinkt. ## Features - 10” x 20.75” heating mat to accelerate and improve the success of seed starting and germination. - Digital heat controller displays real-time mat temperature, which can be adjusted to exact levels. - Eliminates the guesswork of determining heat levels to germinate any seed with no risk of scorching. - Features innovative far-infrared film that warms faster and evenly distributes heat across the mat. - Crafted with IP-67 quad-layer PVC that is flexible, resistant to wear and tear, and easy to wipe clean. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D94XY74G | | Brand | AC Infinity | | Country of Publication | USA | | Customer Reviews | 4.4 out of 5 stars 118 Reviews | | Item Weight | 0.46 Kilograms | | Manufacturer | AC Infinity | | Manufacturer Part Number | AC-SMH3 | | Model Number | AC-SMH3 | | Net Quantity | 1.0 Count | | UPC | 819137024540 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** AC Infinity - **Item Weight:** 0.46 kg - **Item dimensions L x W x H:** 20.75 x 10 x 0.09 inches - **Material:** Polyvinyl Chloride - **Special Feature:** Digital Thermostat Controller ## Images ![AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - Image 1](https://m.media-amazon.com/images/I/61QrEDFXHoL.jpg) ![AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - Image 2](https://m.media-amazon.com/images/I/71tmOawth0L.jpg) ![AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - Image 3](https://m.media-amazon.com/images/I/61iaSR0eoaL.jpg) ![AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - Image 4](https://m.media-amazon.com/images/I/71TVjHEwbFL.jpg) ![AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - Image 5](https://m.media-amazon.com/images/I/71coz1ohfpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well for the money *by D***S on 12 November 2024* I like the thermometer, it's easy to read. ### ⭐⭐⭐⭐⭐ Nur zu empfehlen *by J***S on 28 April 2026* Angaben können nur in Fahrenheit geregelt werden, ansonsten wird die Raumtemperatur über das Steuergerät ausgelesen, NICHT über die Heizmatte.
