Well I have a rack half complete, so I decided to stick down a sheet of flexwatt, put a tub on top, and placed another shelf on top of it. I plugged the heat tape into the thermostat, set it for 100, and it's STILL climbing, after 10 minutes it's only at 93. I remember in your video you said that an advantage to soldering is that it heats up much quicker, does this slowed heat-up time possibly have anything to do with my connections?? Thanks again for your help guys!
