Well its been 24 hours in the new room amd im having an issue. I cannot get a standard temp throughout all the tubs. All are 12inchs of 4inch flexwatt.. Wired to 2 powerbars. Into my herpstat on probe 1. Output 1 is set to 104 degrees. With the probe underneath the flexwatt. In a routered groove. My tubs vary from between 81 to 91. And in no particular order. Not as if jut the bottom ones are cooler. Its all over. One top tub is 83 and one bottom is 89.

The gap between tubs is for air to circulate through. It doesn't look like you have much room between each level.
The way it's set up you could just as easily have put the rats in a box with a few air holes.

check all your connections, check for any bending or obstruction of the flexwatt, any pinching, anything. Unplug and redo ... see what happens... GL

I disagree. If u look at the pictures u can see how the tubs are sloped. There is approx 4inches of open mesh on either side of the tub that is wide open. Not to mention the 2 inches created by the bottom supports that allows air flow on top of the tubs.
Regardig the flexwatt... I was really hoping that wasnt the trouble shooting i would need. All are soildered and taped down really well. I have trouble using my temp gun on the flex watt itself due to its refectivness.. Was considering putting dull tape in the middle of all the strips so that i could shoot it better.

you should just be able to shoot at the black strips, or even on the tubs if you can.

i wouldnt use duct tape. it will just become a sticky goo. not sure what chemicles would be off gassed into the room as well. always use the temp gun on the substrate in the enclosure to know what temp the snakes are actually seeing. not what just the tubs are seeing. you will notice a difference.
as far as the difference in temps go. make sure all the pieces are the same exact length and that the connections are solid.

Edit: just relooked at the pics and realized they dont show how much of a slope the ends of the tubs really have. But its approx 4 inches inward from the top to the bottom.

I was thinking hockey tape. And the black strips on the stuff i got just bounce it right up to the top shelf. Id like to find out if its an issue with the flexwatt itself before i tear it all out. Or if it has to do with how i have it wired.

I see what you're saying.
I guess most people, myself included, don't think that's enough space to allow for air to flow through the tub which is why you see plans that have 9-10 inch spacers between levels. You are not just trying to supply air but to allow air to circulate.
BTW, what space did you save by stacking them closer together? Floor space used is th same. Are you building something above the rack? Just curious.
ETA: I have a rat rack using the same tubs and the gap between the bottom the tub and the next level screen is 5-6 inches.
