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. ## 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.kr/products/241808154-suncore-a7-waterproof-seedling-heat-mat-48-x-20-75](https://www.desertcart.kr/products/241808154-suncore-a7-waterproof-seedling-heat-mat-48-x-20-75) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-29*
