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

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!!

I got these to grow mushrooms. The mats are large and seem very sturdy. The controls consist of a simple dial with "low" "medium" and "high." I set mine on medium to test it out and after about 10 minutes, it was warming up, though not too hot. These should work well for growing mushrooms or for any kind of seed sprouting.

Gave as gift to wife. She intends to use to get seedlings started. 4 stars for now till used

You get two of them .They work extremely well.I use these under 1020 trays and they fit perfectly to keep those little plants babies warm enough to germinate.The temperature control is pretty great to have and you can fit two of them on a wire shelf of 2x4.You can also use these for fermentation and I have used these to speed on some ferments of sauce and Kimchi.

I just can't say how happy and satisfied I am for ordering these pair of mats. I use these for germinating, and I also use them for my clones and small seedlings. In the winter, I'll wrap one around one of my watering buckets to bring the temps up for the little ones. I absolutely love these! And for the price too! One of the very best investments for my grows.

Having extra mat for backup is great. Works well. Need thermometer or hydrometer to set right temp.

I first bought some RK link on here. There was no control [which I knew] but they did not get very warm/hot. The minor extra cost for the Suncore is well worth it. If later I need to move them to the basement or garage for space, this puts out the higher needed heat. I am very pleased with these. A much better option.

I like the method these pads use to heat vs the ones with wire or whatever that creates hot or cold spots. With the temp dial to regulate the heat it really isn't that much more than others with adjustable heat levels and a lot better quality.
