## 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: American plug - Comes with American plug
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!!

## Questions & Answers

**Q: How much watts and amps does this pull?**
A: Watts (power) = Amps X Volts
Description says matt requires 105W in power/energy to operate
Common current in the US is 120V
Just Solve for X      W= ? 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.

### ⭐⭐⭐⭐⭐ Review
*by Y***Y on 8 February 2025*

I'm NOT getting paid for this review and not getting compensated in any form or fashion. I love AC Infinity company, their customer service is second to none and they have top quality growing supplies. I was excited when I found out that a digital version of the heating mat is coming out which I thought would be more convenient and I wouldn't have to use a thermometer/hygrometer to put inside the dome to monitor temperature and humidity to have proper germination and/or cloning rooting success rates but when I received it I was quickly disappointed because first of all for those in colder climates will have issues getting temperature to 80° or above 80° because for some reason even when I set the temperature to get to 110° it takes quite a while to climb to 102° but when I check the temperature with a couple of separate thermometers It shows that the temperature is around 74 to 76° and in order to get it to climb up I would have to put something under the heating mat like a piece of plywood or styrofoam and I add one of the Amazon bubble envelopes too avoid losing any of the heat radiating down to the floor and that definitely helps but if someone needs higher temperatures like 84° for instance I don't think they will be able to achieve that with this heating mat. For the most part the temperature that's needed for my plants for germination is 78 to 80° which is the sweet spot and to get there I have to set the temperature to 102° and it fluctuates between 100 and 102°, which actually keeps the temperature at 78 to 80° F with a piece of plywood under the heating mat and a couple Amazon bubble envelopes stacked on top of each other. The one that I would recommend is the same one but with the dial/knob which works flawlessly and I would need to have the temperature either in the middle or between the first quarter and the middle. Just make sure you use a thermometer/hygrometer inside the dome to dial in temperature and humidity. Here's the hygrometer / thermometer set of four that I highly recommend and they have two options either without a probe or with the probe. The ones with the probe you can only measure the temperature with the probe but to measure temperature and humidity you would need to unplug the probe and put the device itself inside the dome but if you never need to check only temperature then get the ones without the probe because it's a little cheaper and you won't have that probe port open that can get dirty and something can get stuck in there. These are a lot more reliable than those really cheap ones, the black rectangular ones.
