Rack temps?

[tttaylorrr]

Basically i think what im asking is should i take the temp reading from the paper not the tub? Ie point the laser temp gun at the paper above the heat mat area till it reaches 90 degrees.
Thanks for your help.

no, below the paper. you need to regulate the absolute hottest part of the tub your snake can touch, which is over the hot spot BELOW the paper.

and it's my pleasure.
