Which way should thermostats face?

[ZoeFugazi]

ok im havin major difficulties with my 2 tubs as far as temp and humidity go. i think the humidity may be because i drilled air holes on the lid instead of the sides of the tub right?

ok now...in each tub i have 3 digital thermostats. The 2 on each far end ( cool & hot side) are suction cup mounted with the air vent facing down. The 3rd digi thermostat also has digi hygrometer. On that one the vents face back towards the inside of the tank. im getting diff readings...do i need to mount the ones with the vent facing downward so that the vent faces to the inside of the tub instead of down at the newspaper on the floor? HELP!

First off do you mean digital thermometers? A thermometer tells you the temperature, a thermostat is something you hook up to a heating source to controls the heat it outputs.
I’m not sure what you mean by air vent but I’m guessing it’s a thermometer with no probe, which is very inaccurate as its just measuring the air temp. If I’m wrong and just not getting what kind of thermometer you are using please post a picture. You are going to want a thermometer with a probe and have that probe contacting the surface of what you are trying to get the temperature of. Even with those though they have a margin of error and will only give you an approximant temperature. For a accurate temperature reading you need a inferred thermometer.

For the humidiy you can try sealing up a few of the holes you made, adding a bigger waterbowl or adding a humity hide (a hide with moist Sphagnum moss)
