From what little I know, low 60 will slow aging and make burn hotter/faster. Just gently squeeze a stick toward the middle. If you get that nice spongy feeling & bounces right back and not leave a dent, then your fine. If it leaves a dent, then it is too wet. If you get that dry feel, crackles, and just does not feel right, then it is to dry. Don't go crazy with any hydro, let your fingers and how they smoke tell you.
