Thermostatically controlled heating mats

[clearsky57]

So how many folks are using heating mats and what temps do you set yours at???
I have used them and am presently thinking about adding in more to my greenhouse to allow seedings a more stable temp. that way i can moderate my mean temps in the house...

I have used these for decades, generally for seedlings, setting the temp to between 75 and 78 degrees F, depending on the size and hardiness of the plants.
