I got a couple mo' pennies.

Not sure how low temps would be more conducive to mold growth.
Most organisms increase growth with increase in temperature.

And my experience has shown that humidity is the main cause of jar mold.
Since cooler air is generally drier air, low temps. should retard mold growth.

My drying closet is rarely cooler than 70F. and averages ~78F.

Here, it's about air circulation when drying, and moisture content when curing.
If the humidity inside the jar is ~ 70 % or >, mold is assured.
If I burp them down to about 60% they won't mold at any reasonable temperature.
And lower temps make for a long, slow, cure, so I store some jars in the fridge at about 40F.
Since I started putting humidity meters inside the curing jars I have had 0 mold.

So I gotta question the low temperature assumption.
Anyone got some more input in this?
