Sorry I was a little rattled.
They are 36 inch plastic neodesha cages. I at first didn't have the 2 probes from my double ranco thermometer's set up. I put them inbetween the cage and pad on the middle cage and set the thermometer's for 82. On e reads 83 and one reads 81.
I am only temping in the 80's in one little spot. the cool side is in the high 60's which isn't horrible but I was hoping for low 70's.
Ambient temp is 72. They've been set up for about an hour
