Switching from tubs to rack

[Eric00]

I have the same problem. I set my thermostat initially at 93 hoping to get a hot spot of about 90. I found I was getting nowhere close. I kept bumping it up until I reached the highest limit on my thermostat (108) and it gets the middle rack to 92 hot spot (I taped the probe to the middle slot) and the top and bottom to like 88-89. I figured it was just the cheaper thermostat I'm using which is a Jump Start from Amazon. BTW I'm also using the 3 high 28qt tub from CSerpents.

Must be that I need to bump it up more, I let it run all night and it never got me more than 80 degrees. I guess I'll bump it up a few and see where it gets me
