do you mount a Flueker's thermo-hygrometer inside or outside of the terrarium?

lol thats what i thought...my mom was swearing up and down you put it on the OUTSIDE of the glass...hahah makes no sense!

inside. it reads the temperature of the air around it. and you want to know the temp of the inside of your pets cage.
