## Description

Product Description: Seedling mat designed to accelerate the seed growth process by improving germination success rate and release stable heat. Each mat is backed by an innovative Far Infrared film to provide even heat distribution. Provides softer warmth than wire coils to protect seeds from scorching Made of durable four-layer PVC that is resistant to wear and tear, easy to clean and roll for storage. Comes with a waterproof nylon drawstring bag. For the growth of innovative technology seedlings, each mat is backed by an innovative Far Infrared film that creates softer warmth than wire coils and protects seeds from burn. Connected heating controller supports this protection and features an adjustable dial to set desired heat output. Control the mat temperature over time without turning on and off. This can cause seeds to rot due to extreme temperature changes. Threshold levels include low, medium and high SAFETY CERTIFIED: UL Listed (E518635) to meet the safety standards for electric heating appliances and heating pads. It also meets the MET standards for the safety of electrical appliances (certificate #E115128) and ensures non-toxic use for indoor heating applications. These authorizations can be verified through their respective online directories of AC Infinity Inc. The heating mat is also rated for fire retardant and safe temperature regulation. Reached IP-67 rating, the heating mat is sealed along the seams to prevent water and dust from penetrating through. The input protection extends to a 60" power cord and is specially sealed to prevent electrical damage.

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!!
Review: Me gustaron los tapetes, se sienten de muy buena calidad y si me funciona en conjunto con el domo de humedad también de ac infinity, ojalá los hubiera comprado al mismo tiempo para ahorrarme el envío, pero de ahí en fuera funcionan tal y como se menciona en la descripción 👍

## 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.
