terrarium set up q's

[mommanessy247]

1) i know the uth goes under the terrarium but where do i place the thermostat & its probe? &
2) will i need to put anything between the uth & my dresser surface? if so, what works best?
i am trying to work out how i am going to set this thing up, so that when the times comes to do it, i've got it all written down & i know what to do instead of trying to figure it out on the spot and becoming confused and/or frustrated.
thanks in advance for replies.
