Work well, reasonably priced
I have used these heat pads for two things around my house. First, they are great for encouraging seeds to germinate. I haven’t been able to control the temperature, but they won’t cook your sprouts. I’ve gotten good germination rates by using them when I start seedlings indoors in the late winter/early spring.Second, I discovered that they make feral cat shelters nice and toasty on bitter cold nights. Whether they’re the wooden shelters that I built, or the ones I’ve fashioned from plastic totes, the poor cats seek them out. Just put some cardboard between the bottom of the shelter and the heat pad and then on top of the heat pad and you’ve got a warm place for them to sleep. It’s cheaper to use these to heat your animal shelters than buying a whole manufactured unit. Either way, they are a good way to spend your money. St. Francis would approve!

adjustable for accurate temperature control
I bought this heating mat to sprout various medicinal herbs. It worked very well and maximized my germination rates even for difficult to sprout seeds.When I was done, I began using it for something else.I have a little 4 pound dog that gets very cold in the winter on my hardwood floors. He sits in his little dog bed shivering.I took this heat mat, set it at 80 degrees and put it under his bed. He now sleeps comfortably with no shivering. I put a thermometer in the bed that has a wifi alarm, to make sure it didn’t get too hot. It stayed at 80 degrees with no variation. I ended up turning it down to 78, where it stayed with no fiddling with the temperature control.I will use it again in the spring for sprouting seeds, when the pup no longer needs it.I love it when a product can be used for several purposes. The ability to change the set temperature made sprouting seeds trouble free, and being able to set the temperature at a steady rate enabled me to make the pup more comfortable.I couldn’t have used my last heating mat in this way, as it was not adjustable.I am well satisfied with the quality and usefulness of this product.

So far, I’m pleased with the products’ construction and function for the price
I’ve only been using this for about 24 hrs out of the box. But, so far, I’m pleased with the products’ construction and function. The red LED control display is bright and sharp. I followed the instructions supplied with the controller and I had my temperature set point set up in just seconds. My seed starting table is in a basement area that’s around 60 degrees ambient. With an 85 deg. set point, the mat has brought my soil temperature up to around 80F, which is close to where I wanted it to be. It’s probably capable of getting the soil much hotter, but I have had no need to go higher. I don’t believe the product description mentions it, but the controller display is also a thermometer, that shows actual soil temp. Not sure how accurate it is, but most seed starting temps aren’t all that precision. If exact soil temp is a concern, you might want to invest in a precision dedicated soil thermometer to verify. Also the description says the mat accommodate one seed flat? My 20″x20″ will actually accommodate two standard flats, which is why I bought this one instead of one of the small 20″x10″ mats that are offered on Amazon.

proofing bread-update
Tried to use this for a bread proofing box made from a Sterilite tote.. House was 72, this pad could only get it up to 78. The controller worked fine, and with a 75 watt bulb, this controlled the heat to 85, and the box heated up in no time. Just get a controller if you want a proofing box.Updating this. After seeing my review, the seller sent me another pad and controller. Tried it again. I set up the pad in an inverted Sterilite box. Put a thermocouple on the pad and the sensor 5 inches above the pad. The pad did get to 110F, but the box only hit 74 (Room at around 70). So it did help, but I like to proof my bread around 80F, and if the hose gets colder in the winter, not sure the pad will do the job. I am moving my rating from 2 to 4 stars because it is working as advertised (reaching 110F) and the seller was prompt in reaching out to me. And the controller works just fine. It may work for seeds, I don’t know, but while some people use his for bread, I can’t say it works for that purpose. The controller is working for a light bulb I use to heat the box, and that is ideal.Updated – tried this again in winter. Put reflective mylar insulation underneath. Keeps the box at 72-74F now. Haven’t tried hotter, but this is working well for a slow proof at that temp. House temp is 68-70, so working well.

Plant warming pad
We’ve had this warmer for our chilli’s the last few months and it’s a great value for the money. Just plug it in, can’t bet the ease of use and speed of setup. The compact size fit well on our end table and the temp accuracy seems spot on. A great product ð

Inconsistent temperature areas
Temperature ranges on mat are wide. Spots in the middle ate 90 deg f while the outer areas range from 67 to 72.

Must have for indoor seedlings
If you start your garden seedlings indoors, you need this heat mat. This is the second one I purchased. They work great. I start seeds for tomatoes and peppers 2 months before I put them in the ground. Heat mat and grow light are must haves to do this.

Muy bueno sobre todo que es seguro no como los de resistencia… aunque me da la impresión que calienta menos

Compared to the expensive heating jackets at the Beekeeping suppliers this works great. I wrapped this around my storage tank which is inside a insulated box. Set the temp to 100 F and within a week my honey was back to liquid. I keep it at 80F to maintain.

I purchased this mat primarily to use as a proofing mat for bread making and for sourdough starter. It is working perfectly for both. I will also start seeds on it in the spring. It heats quickly and maintains the temperature. The price was very reasonable and delivery prompt. I am very pleased with my mat.
