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. 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. Innovative Technology Each 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 heating controller supports this protection, featuring an adjustable dial that sets your desired heat output. Control the mat temperature over time without having to turn it on and off, which can cause the seed to rot due to extreme changes in temperature. Threshold levels include low, medium, and high. Safety Certified This 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. Review: If you want quality products that do what you need them to do and keep on doing it then ac infinity is the brand to go with. Their products just feel like quality and they perform just as good as they feel. I’m so glad they have focused so much on their line of indoor gardening equipment because it gives growers a high quality option. Anyway, these mats are perfect! I grow thousands of out her plant seedlings and I prefer to use a heat mat while germinating them. The past few mats have fallen short because they use a thermostat that must be inserted into the soil to read the temp. While this may not seem like a big deal, I’ve had the sensor come out before and narrowly avoided frying my seedlings! These mats however use a dial that you can tune to perfectly set your desired temperature (I use a laser thermometer for soil temps) not only is that helpful but it makes it much simpler to achieve your desired results. Another thing I really like about these mats is they are not bulky at all. The technology they use is infrared and not heat coils. Which means it’s EVEN HEAT and with no hot spots like coil mats have. I feel like that’s a much safer option as heat coils, while rare, can short out. They do take slightly longer to reach peak heat but does a few extra minutes really matter when germinating seeds? Not really. If you are looking for a high quality heat mat that will outperform any others you’re going to find, just do yourself a favor and go with these. They won’t disappoint!!

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 A***W on 11 June 2023* If you want quality products that do what you need them to do and keep on doing it then ac infinity is the brand to go with.
