So we have a home built rack made of melamine with belly heat tape hooked up to a nice $200 thermometer. We have the probe taped down in a "dummy" tub underneath the substrate and underneath a hide, as all of the tubs have hides in them. Basically we try to have the probe in the most similar spot as to what the environment is like for all the tubs in the rack.
We have crazy variation throughout the rack when it comes to temperature. For instance, the heat gun is reading the probe tub to be 90 degrees on the hotspot, which is what he have the thermostat set to. I'll go to another tub, and its reading 95 degrees under the hide on the hot spot. 93 in another, 88 in another, etc. Really frustrating when we're trying to make these tubs identical and all the hotspots are different degrees up to a dangerous heat. Could more holes in different tubs be affecting the temp so much?
