Warning: stupid question alert

Okay, I just got a new rack the other day. I'm curious as to the best placement for my probe to my herpstat.

Do I tape the probe directly on the heat tape itself? My one friend will cut out a piece of a bin (same as in his racks), place that over the heat tape and then tape the probe to the plastic, to get a better reading.

How do you have your probes on your heat tape?

I always place the probe direct on the heat as this gives the thermostat the info it needs.

Place the probe directly on the heat tape, but use a temp gun to monitor the inside of the tub's surface. Adjust the T-Stat up or down until you are maintaining the desired temp on the tub surface. Remember, even if you are using a substrate like aspen and have it fairly deep, the snake will eventually move it and have its body touching the surface, so you don't want the surface temp to exceed the proper (safe) range. That being said you probably don't need more than about a 1/4 inch of substrate. If you have an empty tub, you can set up an accurite thermometer with the probe over the hotspot and the body on the end without the heat source. Trust the temp gun over the thermometer, but you can use the thermometer to see that the temps are staying stable.

My substrate in my tubs is straight up paper towels. Thanks for the input! I'm gonna change the placement of my probe then using my temp gun appropriately set my herpstat.
