Low temps for fermentation

[Indy418]

Need to leave town for a few days so I can't monitor fermentation temps on my Belgian Wit I just put in the fermenter. White Labs Belgian yeast--White Labs says its good 67 F. Planned to ferment in the fridge but the highest the fridge will go is 64. Temps in the house hover around 85 during the day. No central air.

Suggestions? Is 64 too low? Any other ideas?

Better 64 than 85+. Since fermentation is exothermic, you'll probably end up fermenting in the upper 60s at the 64 deg setting anyway.
