I'm using two digital thermometers/hygrometers. One is an acu-right and one is a wal mart brand that I forgot. I'm also using a temp gun for the temps but so far the temp is up to par. They're not dimpling too badly, but it was enough that I noticed. They've just got slight areas where they dip a little, about .5 cm or somewhere around there if I had to take my best guess. I'm just freaking out as a first timer.
