I have that same ph and moisture tester, didnt work too well for me but it said if you are in between b and c its water time, nad if it gets too hot go to home depot and spend 20 bucks on a small yet powerful fan and point it directly at the light towards the opening in your closet, it should help!

Good luck again!
