Perfect for indoor gardening, this combo includes a digital controller for precise temperature management, ensuring your seedlings thrive in any environment. ## Description Instructions: 1. Locate a flat, dry surface of the appropriate size for your heat mat. Avoid cold surfaces, and they will counteract the heating ability of the heat mat. 2. Plug the heat mat's electrical cord into a standard 120-volt outlet. 3. Place a propagation tray or other plant container on the heat mat. For best results, cover seedlings/cuttings with a humidity dome. Attentions: Failure to observe the following safety guidelines may result in fire, electrical shock and/or damage to the heat mat. 1. Never allow the heat mat to become submerged in water or any other liquid. 2. Don't place the heat mat on or under any other heating, warming or insulating device. 3. Don't place the heat mat on rough or pointed surfaces, as this can damage it. The digital temperature controller device allows gardeners to select and maintain optimum rooting temperatures for faster seeding or cutting growth. It is compatible with many other heat mats. Tips: The Digital Heat Mat is designed to achieve the desired heat temperature within 5 hours. If it takes longer than 5 hours, or if the mat runs for longer than 5 hours, desired temperatures are not being reached. To conserve power and increase the mat's effectiveness, move the mat to a more insulated surface. You can also add a humidity dome to cover the seedling tray, which makes for heat retention. Warning: Do Not Immerse Digital Controller in Water. ## Features - Reliable Results: The VIVOSUN professional heat mat maintains optimal temperatures around 68-86℉ (20-30℃), perfect for Seedling start and cutting propagation; Made from durable PVC material, it's designed to last - Stable & Uniform Heat: The advanced far-infrared heating technology of this heat pad provides your plant with a warm environment to create optimal conditions for speeding up germination and accelerating the growth rate; The strengthened heating film with double insulation layers ensures this durable mat will not scorch the root and can produce plenty of invigorating dew when being used in combination with a humidity dome - Built to Last: Designed with soft, flexible, and ultra-lasting material, this warming mat goes beyond stringent MET standards; The IP67 rating waterproof surface is easy to clean that enables safe scrubbing; Note: please only use the product indoors and do not immerse it in the water; Equipped with a carrying bag in the package, you can simply roll it up and pack it away, which is handy to move to different places; This product does not specify any expiration date - Great Combination: This warming mat also runs on only 20 Watts to help you save on electricity; Combined with VIVOSUN thermostat, it can not only use for plant sprouting and other indoor gardening but also for home brewing and terrarium warming, meeting your different daily needs - Innovative Heating: With the radiate far-infrared light wave, this seedling heat mat makes the heat source softer and provides enough heat, which can be heated up to 40 β„ƒοΌˆ104℉）at an ambient temperature of 20-25 β„ƒοΌˆ68-77℉）in minutes; We recommend using it with the VIVOSUN thermostat controller and humidity dome ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016MKY7C8 | | Best Sellers Rank | #130,579 in Garden & Outdoors ( See Top 100 in Garden & Outdoors ) #303 in Thermometers (Garden & Outdoors) | | Capacity | 10"x 20.75" | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (11,863) | | Date First Available | 9 January 2016 | | Is Assembly Required | No | | Item Dimensions LxWxH | 11 x 11 x 27 Centimeters | | Item Model Number | VS-330101 | | Item Part Number | x000vnd2y3 | | Item Weight | 454 g | | Manufacturer | rotary | | Primary material | Plastic | | Shipping Weight | 0.75 Kilograms | | Weight | 1 Pounds | ## Product Details - **Brand:** VIVOSUN - **Colour:** Mat&thermostat Combo - **Item Weight:** 454 g - **UPC:** 742920469795 ## Images ![VIVOSUN 10"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set MET Standard - Image 1](https://m.media-amazon.com/images/I/71nbaZc+Q3L.jpg) ![VIVOSUN 10"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set MET Standard - Image 2](https://m.media-amazon.com/images/I/51eA5Nt1vHL.jpg) ![VIVOSUN 10"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set MET Standard - Image 3](https://m.media-amazon.com/images/I/51P-t6JsNXL.jpg) ![VIVOSUN 10"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set MET Standard - Image 4](https://m.media-amazon.com/images/I/511ypSCs4TL.jpg) ![VIVOSUN 10"x20.75" Seedling Heat Mat and Digital Thermostat Combo Set MET Standard - Image 5](https://m.media-amazon.com/images/I/41X92XTVrhL.jpg) ## Questions & Answers **Q: Anyone use this on a 20 gallon long tank for a leopard gecko???** A: I use mine to heat my 29 gallon reptile aquarium. Get the thermostat for it because these mats run at about 100 degrees without it. **Q: can you put splitter on controller and run multiple mats?** A: You surely can, the 1020 mats are only about 20 watts each. What you need to watch out for though is after you get various brands of mats. They are not equal. Some run hotter than others. If you place your temperature probe in a tray on a hotter mat and set it to 85F, one of your cooler mats may only be maintaining around 78F. **Q: What do you do to get this mat to lay flat? Mine seems permanently creased and bent from its shipping position.** A: I had to put something about the same size on it for a couple of days to get it to lay flat. Even a piece of wood with a weight on it would work, about 5 pounds is all that's needed. Hope this helps! **Q: Can the probe be left in the air to read temperature? I'm trying to keep an enclosed container warm at a set temp.** A: Yes, it can read room temperature, however it's the soil temperature that helps the seedlings grow. Also, I believe when it reaches set temperature it has a delay before turning back on. So use sand or rocks to retain the heat longer. ## Frequently Bought Together - VIVOSUN 10"x 20.75" Seedling Heat Mat and Digital Thermostat Combo Set, UL & MET-Certified Warm Hydroponic Heating Pad for Germination, Indoor Gardening, Greenhouse - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter Β± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Yellow Blue, UL Certified --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/210707703-vivosun-10x20-75-seedling-heat-mat-and-digital-thermostat-combo](https://www.desertcart.jp/products/210707703-vivosun-10x20-75-seedling-heat-mat-and-digital-thermostat-combo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-27*
