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.

I use them for brachys and hookerae I believe I read somewhere that one of the nurseries (Paph Paradise?) uses them to keep their roots from staying too cold/wet and rotting.

All of my brachys have done well with this method, so I continue to use it. All of my orchids are in my house office (PNW/Oregon) and temps are typ in the low 70s during the day and I open the windows at night to let the temps drop.

I set the mat at 70.”
