Wow awesome suggestion!
I had spiking temps in my Rack with Herpstat after moving to a cooler place. I also had my probe covered in aluminum tape like most people seem to do...
I did exactly what you suggested in the pic and now the Herpstat is stable with in 0.06 up and down to where I set it.
I would recommend making a new thread out of this pic/sugestion and making a sticky under Husbandry as it seems to help new and old keepers alike! :banana:
Thanks again! and yes definitely learn something new everyday! :D
