I need advice on thermostat probe placement

[The Serpent Merchant]

Both strips heat the entire rack. The rack is 6 shelves high and the two strips of flex watt snake up each shelf. I see you seem a bit skeptical of the post in regards to placing the probes in the tub and I'm new to rack systems, can you explain what you think would be the best way of going about probe placement in my setup. Thanks.

ok, what i would do is place both probes on the center shelf. The top and bottom of the rack will always be different temperatures since heat rises. if you have a probe at the top and one at the bottom with flexwatt that goes through all of the levels you will have very inconsistent temps. I would try to get the middle shelf to 90 degrees. this allows the top of the rack to be warmer 92ish, and the bottom to be cooler 88ish while still being in the ideal range of 88-92 degrees.

My issue isn't putting the probe in the tub, that is a viable option. No my issue is the whole dimmer shorting out thing.
