I'd read about hanging it outside, but I don't have any place where it would be protected from rain. Our nights have been getting down to mid-50s as well and I didn't think the cold would do it any good. So that's why I opted to hang it indoors in a warm shady spot.
I've also seen videos where they hang it anywhere from 7 days to 1 month. I must have missed the one where Maria said 6 weeks, I watch a lot of her videos (or I just don't recall it, I was looking up so much info at the time).
