got my first snakes last week. my set ups seems to be great, after much worry about them (i worry about everything) i think i got almost everything down pat. here are my only problems:

i have a herpstat 1 with 4" flexwatt wired in parallel. the top piece is the one with the probe. it has the best readings, closest to 90 degrees unless the probe gets moved. how do i keep the probe from moving? i have it taped down with metal tape but not taped directly to the UTH, i have it taped along the corner of my rack and then the probe rests on the UTH. do you guys have any pictures?
the second piece of flexwatt seems to not heat up as much. when i do my temp gun readings, it comes at 80-89 but not usually 90. i think i may be checking at odd times, or when i check i dont go fast enough and it loses a degree or two.

my acurites are odd. both of them give me almost perfect readings, 91 degree hotspots, 79-82 cool side. the humidity for the good acurite reads at 69% and thats when the only water source is a small bowl with a closed lid on one tub and a normal bowl on a lidless tub this reads at 69%. lid tub has plenty of holes. the other tub has less holes, but no lid with a space between the rack and this reads at 66%. so is 66% and 69% humidity too much? how should i lower it? more holes, or do you think acurite is not acurate?
