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.

Very versatile. I use it for both starting my seeds prior to planting as well as a mat to put my sourdough starter on.

I ordered 2 of these seedling heating mats from Amazon. Neither of them appeared to be radiating the slightest bit of heat; even when turned all the way up. Another customer contacted me about the same issue. But when I reached out to AC INFINITY, they contacted me back promptly, and made the situation right, on the spot. OUTSTANDING CUSTOMER SERVICE! Truly grateful.

Unfortunately I can't check to see whether it is the correct temperature. It doesn't seem to get very hot even though the temperature control goes way up. My plants all germinate even though my instincts tell me to set it ten degrees higher that the suggested temperature for certain seed germination. It's easy to operate and is the correct size. I do prefer the heat mats with a temperature gauge that you insert into the soil though.

I received this AC Infinity SUNCORE seedling mat to help maintain ideal temperatures during a recent cold spell, and it’s been a lifesaver for my greenhouse plants. The mat consistently kept my seedlings warm, holding steady between 75 and 80 degrees, even when the greenhouse temperatures dipped into the low 60s during the day. It gave me peace of mind knowing my plants were protected and thriving despite the chill.The digital thermostat controller was easy to use, letting me dial in the exact temperature I needed. The mat heats evenly, so every tray stayed warm without hot spots. It’s also waterproof, which was great for handling the inevitable spills during watering without any worry about damage.After a few weeks of use, I’m impressed with how well it’s performed. It’s a simple, reliable solution for keeping seedlings happy in cooler weather, and I’ll definitely be using it for future germination projects. Highly recommend it for indoor gardeners or anyone needing consistent warmth for their plants!

The best seedling mats I've ever used. Adjustable temperature controller with digital display for dialing it in exactly but probably more important, no hot spots. I have cooked seeds using cheap mats before and it's cost me quite a bit of money. This mat distributes the heat evenly and won't cook your soil if you set it down in the wrong spot. Accurately heats from 32 degrees all the way to 122 degrees, so it can be used in very cold environments and still be effective. I've got 2 of these now, 1 for seedlings and the other for dialing in the temperature on my compost teas. If i set it under 4 gallons of water in ambient temps and set to 110, my teas reach 75 degrees which is optimal for microbe growth. Very effective and multiple uses. A must-have product for the serious grower.

Works exactly as it should, heats up evenly and disperses the warmth properly. Working very well for me and I am pleased with it. I always plug mine into a surge protector outlet strip. Recommended.

I like the thermometer, it's easy to read.
