They are well made, and, when paired with a controller and temperature probe, give precise bottom heat to flats of seeds or cuttings. I succeeded with the germination of some seeds that had failed to sprout for me before. Review: Seeds sprouted in two days! - I was BLOWN AWAY, yes you heard me right, BLOWN AWAY when I planted some pink zinnias and purple basil TWO DAYS AGO and they sprouted using these mats. I ordered the two pack during Black Friday $17.60 - should have ordered more, if I knew how amazing these were, dang it. Now I have to wait for another sale!! I am using these mats in combination with another Black Friday purchase I've made, the Bstrip DIY Plant Shelf on desertcart ($169), and these two products together has changed my plant-growing and cooking hobbies forever! To sprout my seeds I use tofu containers because they are nice and square and fit on these mats well, and they are cheap because I already have them and when I am done they can go into the recycle for plastic. I drill holes into the bottom, that's the only real work using the tofu containers. I can get 8 tofu containers onto one mat. I use a sterile seed starting formula like Jiffy, wet the soil thoroughly in a bucket, press the soil into the tofu containers to allow excess water to drain out. To plant my seeds, I use a rounded chopstick to poke holes into the soil, and a fine tweezer set such as the 6 pcs Kaverme fine precision tweezer set $6.99 (also purchased on desertcart), then cover the seeds, place the tofu containers into BlueSky Multi-Purpose Food Storage Bags Gallon size $4.96 (desertcart) and use the twist ties to seal. I like this set up because I don't have to worry about water getting onto my floors and the plastic bags serve as mini-greenhouses to speed up germination. I've also started to place my water propagated plants onto the heating mat to speed up root formation as I've seen a lot of gardeners do on social media. I use these heat mats also for my sourdough starter, which has been great because the bottom heat is just right enough to speed up the fermentation without having to use my oven/light. I've tried placing sourdough starter in my garage, but it's still not warm enough, and I live in the tropics! ## 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 - Multiple Uses: This 10" x 20.75" heating pad with a 5.7ft power cord is suitable for standard 1020 trays and slightly larger than comparable mats on the market; It also runs on only 20 Watts to help you save on electricity; 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 ℃（104℉）at an ambient temperature of 20-25 ℃（68-77℉）in minutes; We recommend using it with the thermostat controller, it is convenient for you to adjust the temperature manually ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #26,470 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #8 in Plant Heating Mats | | Customer Reviews | 4.7 out of 5 stars 8,124 Reviews | ## Product Details - **Brand:** VIVOSUN - **Color:** Black - **Item Weight:** 0.65 Kilograms - **Unit Count:** 2.0 Count - **UPC:** 742920469658 - **Global Trade Identification Number:** 00742920469658 ## Images ![VIVOSUN 2 Pack Durable Waterproof Seedling Heat Mat 10" x 20.75" | UL & MET-Certified Warm Hydroponic Heating Pad for Germination, Indoor Gardening, Greenhouse - Image 1](https://m.media-amazon.com/images/I/81Fsn0nWsxL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: So just to be clear this is not ul approved and has not safety features , fuses or overheating safety? correct** A: I just received two of these heating mats. Yes! It is marked on each mat "UL approved" **Q: Can i put this mat in between dirt** A: Yes, it's waterproof. **Q: Is it safe to plug it in indoors and use it outdoors?** A: You can use it indoors. A regular heating pad you buy at a drug store gets much warmer, so ya it's safe. **Q: Is the plug safe for outdoor use?** A: if you mean can rain get in it, the answer would be no. However, i have this in use in my outdoor greenhouse, though covered by greenhouse plastic. if you are concerned about the weather, i found this thing at Home Depot by the Christmas lights. it is a hard plastic tube, that has a soft rubber on the ends, and is sliced in half lengthwise. you can put a plug down the middle, and close the tube around it making it pretty water tight. i bought several for areas around my farm with plugs that are outdoors. This would work if you are plugging into an extension cord. (My friend uses her heat mats on her covered patio. not a concern there either. but, if exposed to rainfall, I suggest looking for that cord cover i described above. (It is sturdy. not flimsy.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for germinating "fussy" seeds. *by A***R on August 8, 2026* After one seedling starting season I can recommend these pads highly.

But then after leaving it on overnight under a filled seed tray, I could easily feel the warmth. It's such gentle heat that it just takes a while to get the soil up to temperature, but once it does, it creates a good 15 degrees F or more difference between the soil temperature and the surrounding air temperature. Last year many of my seeds failed to germinate and I suspected that they rotted in the cold damp soil. My house just isn't warm enough in late winter/early spring to get seedlings going. But this product kept the soil pleasantly warm to the touch, and I had seeds sprouting in just two days! Then the seedlings grew like gangbusters in the warm soil--in fact, they grew so fast I had to take the heat away so they wouldn't get too big before it was safe to transplant them to my garden! One tip I learned: the heat is of course going to be highest in the middle of the seed tray, and the cups along the sides that are more exposed to open air will be coolest. So it's a good strategy to plant heat-loving seeds (tomato, pepper, eggplant) in the middle and cool-tolerant seeds (spinach, broccoli, lettuces, radishes) along the sides. Also, since this speeds up germination and growth so much, you might want to plant a little later than you usually would! Otherwise, like me, you might get plants actually starting to blossom in your window in mid-April! ## Frequently Bought Together - VIVOSUN 2 Pack Durable Waterproof Seedling Heat Mat 10" x 20.75" UL & MET-Certified Warm Hydroponic Heating Pad for Germination, Indoor Gardening, Greenhouse - VIVOSUN Digital Heat Mat Thermostat Controller, 40–108 ºF 1000W for Reptiles, Seedlings, Germination, Incubation and Fermentation - 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 --- ## 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.tw/products/19488928-vivosun-2-pack-durable-waterproof-seedling-heat-mat-10-x](https://www.desertcart.tw/products/19488928-vivosun-2-pack-durable-waterproof-seedling-heat-mat-10-x) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-12*
