AC Infinity SUNCORE H3, Seedling Mat 10” x 20.75” with Digital Thermostat Controller for Exact Temperature Levels, Waterproof Heating Pad for Indoor Gardening, Hydroponics, Germination, Cloning

Perfect even heating and excellent quality.

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.

I am so impressed with this mat. I have several other less expense mats from various brands. This is SO MUCH BETTER! It lays flat, heat goes clear to the edge of the mat. The digital controller is an added bonus. Definitely worth paying more for. As the rest of my other mats wear out I will be replacing them with the AC Infinity ones!

First time starting from seedling and this mat has been extremely helpful! I'm brand new at this but I already have some sprouting and this is very exciting!

Had to send back.. mat would not get warm hardly and I turned it all the way up and it still was barely warm to the touch

The AC Infinity sun core H3, seating mat is the perfect size for just about any seeding box. Functions just like any other seeding mat. Extremely easy to use. A great value for the money. The digital temperature reading is a very nice added a bonus. And made of high-quality materials. However, the only flaw that I did find was in my opinion, the cord between the mat and the digital controller is a little too short. Other than that, I feel it’s an excellent product.

A very useful tool for indoor gardening and seedling cultivation.

I used this inside a large plastic container to make a humidity dome for some plant cuttings I had received in December. The mat worked exactly as advertised, and kept an accurate and constant temperature of 75 degrees when set at 75 degrees (there was a thermometer in the box). I had several pots in the box and had good results with all cuttings. Overall the mat performed exactly as expected, and was worth the money. I’ll be using it again this winter for some sensitive plants.

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

Absolut die beste Heizmatte . Im Vergleich zu meinen anderen Matten verbraucht diese von AC die Hälfte an Strom !

جيد وممتاز ولاكن لاينصح به لمن يزرع بتربة لانه غير دقيق بدون مسبار لضبط حرارة التربة والارقام غير دقيقة ١٠٠٪؜ يجب ان تضع كرتون تحت الوساده وقماش او كرتون فوقها لتضمن عدم ضرر بذورك وشتلاتك

Top! Macht genau was es soll.

Tolle Heizmatten, hält die Temperatur konstant auf die angegebene wunsch Temperatur, auch die Verarbeitung ist top, habe inzwischen zwei dieser Heizmatten und bin absolut begeistert.
