I have my system built and thermostats set up. I have my helix set at 88 degrees and the Ranco set at 92 degrees for my back up. Front of the tub temp is around 78 degrees and rear tub heat is showing around 84 degrees. I do have 3 inch heat tape for belly heat. What temp do you have at the front and rear of your racks? What will be the best thing to put in the tubs, paper towels or go with the coco husk bedding I have them on now. Naturally I plan on feeding them right in their tubs so I am leaning towards the paper towel beding so I dont have to worry about them ingesting anything.
