Okay I feel a bit foolish asking this but there are no stupid questions right (well, few stupid questions).
Where should I place the probe I hope to pick up ambient temps. I have the cool side probe right near the substrate by the hide, I have the hot side probe inside the hot hide- so where is "ambient" does that mean like in the middle half way down or in the middle down by the substrate or in the middle near the top? I just want to be sure I get a good reading for my thermostat because I may be out of town all day saturday and it is supposed to really heat up around here which will affect my outside temperature and thus my tank temp - so since I will not be around all day to make sure it doesn't get too hot or cold I want to make sure I do this right.
