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.

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 ### ⭐⭐⭐⭐⭐ Great for mature indoor plants in cold climates *by T***. on January 6, 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).

Set up is neat and easy. Simply wrapping the mat the opposite direction gets rid of the curved memory. Lay it out, plug it and a light comes on telling you it is working. You can feel it working in seconds. The material is easy to sanitize. The manual contains directions for just about everything Suncore makes. The storage bag for the mat is nice but I'm not sure that I will ever use it. I bought this on Amazon last April and am using it for the first time. I'm happy, but as I check the Amazon and ACINFINITY sites, I'm not certain that I can purchase this exact item again. ## Frequently Bought Together - AC Infinity SUNCORE A7, Waterproof Seedling Heat Mat 48" x 20.75" MET & UL-Certified Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning - AC Infinity SUNCORE A3X2, Dual Waterproof Seedling Mats with Heat Controllers 10" x 20.75", UL & MET Certified Heating Pads, for Indoor Gardening, Hydroponics, Germination, Cloning - AC Infinity IONBEAM S16, Full Spectrum LED Grow Light Bars 16”, Deeper Penetration Samsung LM301H EVO Diodes and Digital Dimming Timer Controller, for Veg Bloom Indoor Plants, Grow Tents, Greenhouses --- ## 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.hr/products/241808154-ac-infinity-suncore-a7-waterproof-seedling-heat-mat-120x50cm](https://www.desertcart.hr/products/241808154-ac-infinity-suncore-a7-waterproof-seedling-heat-mat-120x50cm) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-11*
