Its durable quad-layer PVC construction ensures flexibility and easy cleaning, while IP-67 waterproof rating and UL/MET certifications guarantee safe, reliable indoor use. Perfect for accelerating seed germination, hydroponics, and cloning, it’s a must-have for serious indoor gardeners aiming for thriving roots and faster growth. ## Description Product DescriptionA seedling mat designed to improve germination success and accelerate your seeds’ growth process by emitting steady heat. Each mat is lined with an innovative far-infrared film that provides even heating distribution. Because it produces softer warmth output than wire coils, your seeds will be protected from being scorched. The seedling mat’s steady 80-87°F (27-31°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. Includes a water-resistant nylon drawstring bag.Safety CertifiedThis heating mat is UL-certified (E518635), achieving safety standards for electric heating appliances and electrically heated warming pads. It also meets MET standards (certificate #E115128) for electrical appliance safety, ensuring harm-free use in indoor heating applications. These certifications are verifiable through their respective online directories under AC Infinity Inc. The heating mat is additionally rated for fire resistance and safe temperature regulation.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 60-inch power cord, its connection specially sealed to prevent electrical damage from occurring.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. Review: Living in Michigan, growing indoor during the cold winter months can be a challenge, especially if you use LED lights and are growing in an area that's not well-heated (i.e. an unfinished basement). I bought these to help increase the temperature of the root zone for mature plants in five-gallon fabric Smart Pots, as well as raise the temperature in the tent overall, since an oil heater in the room outside the tent wasn't quite cutting it. Having purchased an AC Infinity fan, I figured I'd give these a go, as the quality seemed to be good, the price was competitive (not the absolute cheapest, but not the most expensive) and the product descriptions were the most detailed. These mats hold a consistent temperature of right around 90-95 degrees Fahrenheit, but there does seem to be a slight bit of variation between the two mats I purchased (not enough to matter, for my purposes). I found that I needed to use two thin plastic saucers (the cheapest kind available) instead of one saucer, as that extra couple of millimeters of space between the mats and the pots keeps the soil from getting too hot. So, make sure to measure the temperatures of your root zone and adjust spacing between the mats and the pots accordingly, depending on the plants you're growing and the type of pots and saucers you use. I also put two-inch foam insulation board underneath the grow tent, and this also seems to be helping keep temperatures warmer and steadier. Measuring the soil temperature with a probe, I get a reading in the mid-70's, which is about a 15 degree increase from the temperatures I was getting without these mats—exactly as advertised. If your soil is getting too cold for ideal growth, I'd definitely recommend these—especially combined with some foam board insulation to decouple them from the floor. The only thing I wish these mats had are temperature controls (ideally with WiFi control) so you can dial up and down the temperature, as needed. Yes, controllers can be purchased separately, but still... it'd be nice. But for the price, they're great, and do exactly as advertised. Review: Lovely and large! A must-have for seedling starting. ## Features - A heating mat designed to accelerate and improve the success of seed starting and germination. - Features an innovative far-infrared film that warms up faster, and distributes soft heat more evenly. - Crafted with IP-67 quad-layer PVC that’s flexible, resistant to wear-and-tear, and easy to wipe clean. - Verifiable UL (E518635) & MET (E115128) certifications for electrical safety thru online directories. - 48 x 20.75 in. | 80-87°F Heating Range | Warms up to 20°F above Ambient Temp. | 105W | Inc.

X 120 ---> W/V equals A 105W/120V = .875A **Q: Can you use a thermostat with this?** A: So far out of four AC Infinity Suncore mats [2X 48x20] [2X 20x20] THREE mats overheat my seed trays. I've lost FIVE 72 cell trays all seeded. Puzzled by NO germination, I used a meat thermometer and the readings in three of the trays was 95-100*F and the fourth was 75*F. Either AC Infinity Suncore mats have zero quality control or the overall quality is POOR. Be aware these mats will bake your seeds killing the seed germ. If you have them use a probe thermostat. **Q: What temperature is L M H?** A: Put your seed tray under a grow light, preferably with a dome. Then lay a thermometer underneath the dome on top of the seed tray. Then turn the thermostat to medium; Wait for about 6 hours and see what the temp. is.In my case it was about 85 degrees ; I then turned the thermostat between low and medium and it went to 82 degrees.( I put a piece of insulation between the wood shelf and the seed mat.) My seed tray is in the basement; The air temp. is 67 degrees .So the mat raised the temp in the seed tray about 15 degrees. Now, I hope I have good germinating seeds. **Q: Can this be hvac taped to the back of a terrarium for inside ambient heat?** A: I would not that's not what it's for. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***. on 6 January 2021* Living in Michigan, growing indoor during the cold winter months can be a challenge, especially if you use LED lights and are growing in an area that's not well-heated (i.e. an unfinished basement).
