Kind thanks all!
I made a quick trip to pick up some supplies.
I grabbed 2 of the digital Acurite Thermometers and in case I switch her to the tub method I also grabbed a 6.2qt plastic tub with latching lid (into which I will drill air holes) and 2 plastic 6" bowls that I plan to cut for hides (they did not have any of the flower pot holders like the article called for).
I'll run by Lowes later this afternoon and grab that Lutron dimmer. Thank you!
For now...
Step 1 - Replace crappy stick-on thermos with new digital acurites.
Step 2 - Drill holes in 6qt tub and cut plastic bowls for hides in case BP needs to be transfered.
Step 3 - Go to Lowes for Lutron dimmer
Step 4 - Plug in dimmer to UTH, wait 8 hours, measure temps and humidity
I'll upload updated pics after I get all of this done to make sure I'm on the right track.
Again, thank all of you very much!
