So I just built my new rack out of an old desk and i am having trouble with the temps I was wondering if yall might have some suggestions. I am using Flex watt heat tape, and its running off a ranco. My temps on the first row of the rack are perfect 86, the middle row is 90 and the bottom sits around 84. I was wondering if there is any tricks to make them a little more consistent. The heat tape is 1 continuous strip snake'd from top to bottom. I have the thermostat running at 87-88. If there are any tips yall have or any more information needed please let me know thank you very much.
P.S. this is just the testing phase of the rack so there are no animals/water/bedding just empty bins.
