where to put prob

[Drew87]

Ok so ive had my new rack for about 3-4 weeks i just moved it back to my place from my girls. at her place all the temps were the same but now i cant get them all to match im putting the prob in the tub under the hide on the warm side but it will show 91* and two tubs down reads 85* and im useing a dig temp gun so i dont know what im doing putting prob in the wrong spot?

Is it sitting on the floor? I had to pick my rack up off the ground to get the temps right. Heat rises and the bottom level would be as low as you can get.

I have my racks (4 of them, stacked 2 high and next to each other) on a table and sitting on 3" of foam insulation and my lower tubs are still a little cooler than my top tubs. I keep the bottom tubs empty and use them as spares when cleaning out dirty tubs every morning!

see thats weird becuase my buttom ones get hotter then the top tubs explaine that haha
