I am having trouble equalizing the temps in my rack - it is a 5 shelf 41q rack.

The difference from my lowest shelf to my top shelf is about 6-7 degrees!!

I have run every test I can think of and i have concluded that the problem lies not with the equipment. I'm using 11" flexwatt with a herpstat and they all run at very similar temps when I place them on the same shelf???

I have my probe on the middle shelf between the flexwatt and shelf.

How do i get more equall temps in my rack?? This is strange...


Thanks

Chad
