This is a basic heating mat but it does have a control that allows you to pick a general range of heating. It's not thermostatically controlled, that's a more expensive item if a thermostat is built in or if you're by a separate thermostat to control the mat. It has a control that allows setting it to a certain range but there's no thermostatic control that is measuring to see what temperature you're actually getting and giving feedback to raise or lower the temp. But it did the trick for me. Based on the reviews from other people I put it on a piece of cardboard which helps keep the heat going in the right direction. I used a thermometer to test the temperature of my soil after it was on for a few hours, adjusting the dial upward and downward to get the temperature I was looking for. These heat mats don't have a specific temperature as much as they have a differential above the ambient temperature in the room. So this heat mat is unlikely to start peppers in a cold greenhouse. But in my house it worked great and the price was right.

I wish I got this sooner. It makes germination much easier. No more looking for a warm spot to put the seeds while they germinate in a towel. This is water resistant and very durable. The controller is very simple and easy to use. I never need to go above medium heat. If you are working with clones, this is also a must have. It makes propagation a breeze. It adds just enough warmth to create the right amount of moisture in the enclosure.

I use this in the winter in my cats bed. She loves it

Quality as always. Fast delivery. THANKS AC INFINITY!

Set up is very basic but my issue is that it does not want to maintain a certain temperature when you set it. Plug in he unit, rotate the thermostat dial to desired temperature and you can feel it heating up. 5-10 minutes later you adjust the thermostat if needed. Next morning you check the temp of the mat and it feels like it's not even on.. something isn't working.
