thermostat probe placement

[PitOnTheProwl]

I know that Dion at spyder robotics (herpstat's designer) recommends against using foil tape on his probes. I changed from foil tape on his recommendation and found the temps actually stabilized after the change I don't need to have the set point much higher than the actual temps.

I havent had any problems with the foil tape at all, then again I check mine several times a day AND had my rack up and running for two weeks before animals were in it.
I have not found any reason not to use foil tape yet.

***I also only have a 2-3 degree difference between set temp and actual temp***
