Any out there you can control.......like "high, medium and low?" They all seem to be one universal setting. If you know of one, send me company info to buy online.

Here is a thermostat designed for controlling a heat mat.

This is the thermostat for the mats they sell. Not sure why I can't pull up the prop mats themselves, they have 22" x 44" size which is pretty handy (they also have an 8' long mat).

the thermostats made for the germination mats work great. place the sensor in one of your pots right at seed level. i have found they hold soil temps within a plus and minus 2 degree range at the most when they cycle on and off. you still need to play with it a bit and check the actual temp reading of your mix at seed level and adjust your thermstat setting to compensate if it tends to run a little hotter or cooler.

also, actual temps at seed levels in pots towards the center of the mat may run a degree or 2 higher with pots sitting together in the center as opposed to pots on the outside edge of a grow mat in my experience.
