Its innovative far-infrared film delivers fast, even warmth to accelerate seed germination and propagation without scorching.

The seedling mat’s steady 32-122°F (0-50°C) temperature range heats the rooting area by up to 20°F above the ambient air temperature. It uses a durable quad-layer PVC that is resistant to wear and tear and is easy to clean and roll for storage. Achieving an IP-67 rating, the heating mat is sealed along its seams to keep water and dust from seeping in. This ingress protection is extended to the power cord, its connection specially sealed to prevent electrical damage from occurring.Innovative TechnologyEach mat for seedling growth is lined with an innovative far-infrared film that provides even heating distribution while producing softer warmth output than wire coils, protecting your seeds from scorching. Its connected digital controller supports this protection by allowing you to set your exact desired temperature. The controller conveniently displays the mat’s current temperature, making it easy to program your preferred heating level and view the change in real time. Modify your seedling mat’s temperature as needed without guesswork, which can otherwise cause seeds to rot due to extreme changes.ApplicationsBest used for seed germination and propagation, this seedling mat is primarily set indoors (e.g., in basements and terrariums) to jumpstart the rooting stage. For best results, you may use a greenhouse dome over your seeds to provide humidity and supplement their sprouting. The seedling mat can also be used for home brewing and fermenting beverages, as well as heating pet enclosures for reptiles.. ## 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 | |---------------|-------| | Product Dimensions | 52.7 x 25.4 x 0.22 cm; 458 g | | Part number | AC-SMH3 | | Manufacturer | AC Infinity | | Item model number | AC-SMH3 | | ASIN | B0D94XY74G | ## Product Details - **Brand:** AC Infinity - **Colour:** Grün - **Unit count:** 1.0 Count - **UPC:** 819137024540 ## Images ![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) ## Frequently Bought Together - 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 - AC Infinity Heavy Duty 3mm Thick Humidity Dome Germination Kit with LED Grow Light Bars, Drip Tray, Seedling Tray, Vented Height Extension Panels for Seed Starting, Cloning, Indoor Gardening - AC Infinity CLOUDFORGE T3, Plant Humidifier 4.5L with VPD Humidity Controls, 10-Level Precision Vaporizer, Extendable Targeting Hose and No-Leak Seal for Grow Tents --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/713780011-suncore-h3-seedling-mat-10-x-20-75-with-digital](https://www.desertcart.co.th/products/713780011-suncore-h3-seedling-mat-10-x-20-75-with-digital) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
