This thing seems to work pretty well. I use it in germinating and it really seems to work well. I have a 9x19 hydromat with it.

This is a handy device for controlling power to something in response to heat sensed from its tethered sensor, and its easy to use. You can control many things by plugging them into a power strip plugged into this controller, up to something like 500 watts. Presently, I just have it controlling a small 17 watt heat mat as my garage gets too cold at night for some of my seedlings, but its nice to know I can add other things.
I did some accuracy tests of this digital thermostat with my heat mat by placing the thermostat's heat sensor with that of a digital thermometer and found them to agree within a degree or two Fahrenheit. You can put the sensor probe inside the soil if you want to control root temperature, or positioned in the air if air temperature is your concern, but never into water or other liquids.
If you have problems with your heat mat warming up and suspect this controller, you can plug a power strip into this controller and your heat mat into the power strip along with a small test lamp to see that power really does turn on when it is supposed to.
I really like this interesting and very useful device and am happy that I bought it, though I would be happier if it were made in the good `ol USA instead of abroad.

arrived early and in good condition. It was less expensive than the identical items that I purchased from a commercial greenhouse.

Thermostat didn't work. Propagation mat worked fine, but when plugged into the thermostat the thermostat took the correct temperature readings, but despite having the power light on, and the light stating that it was heating, I watched the temperature drop within a matter of 30 minutes after having the mat heated up before plugging it into the thermostat. Almost makes me think I'd be better off spending $10 on a outlet timer from the hardware store and just having turn on periodically to keep the seedlings warm. The other 1 star review was spot on too.
Totaly awesome Heat Mat monitor. February 3, 2010

Works like a charm.
Connect the Heat Mat monitor's power cord into the wall, then connect the seedling heat mat into the monitor.
To set the degrees is very easy. Hold down the button "SET" until the numbers are blinking. Then using the up and down arrows, set the desired temperature.
There is a little wire with a plastic white tip that hangs from the monitor.
Push the white part into the soil for temperature reading.(Once temperature is set, do not be alarmed when your heat mat reaches its maximum temperature you set it to then the Heat Mat monitor temperature will go up and down 3 degrees to prevent over heating)
This is very helpful for starting seeds.
