Temp fluctuation during aging

[tonyportale]

Hello,
I bulk age (3 gal and 6 gal.carboys) in my 3' x 4' x 9' closet in my basement. I've noticed that the temp in the closet, with door closed, is fluctuating between 52 - 58 degrees. Is this O.K.?
Maybe I should keep the door open to the main basement living area to help stabilize the temp.

not if the living area is warmer....52-58 is not the worst that it could be,....what you could try is placing a blanket or something similar over the carboys to even out the fluctuations
