I’d like to purchase a greenhouse heat mat, and while searching find some come with a temperature controller (more $) and some come w/o a heat controller. I happen to have a spare Inkbird 308 Temperature controller that can control power on/off to any device via a temp probe that senses a value that I can set.
Would the 308 Inkbird I already have function similar to the way a mat that comes with a temp sensor also function? This would save me $30 if I just bought the heat mat and could set the Inkbird to turn off at 78F (for example). I guess I’d simply lay the probe on the mat and tape the probe down flush on the mat to ensure full contact? Any ideas…is this a plausible idea?
