Lake Arrowhead and Big Bear will low into the mid-20's during winter. Some wil say that 20* would be fine, some say it's on the bubble, and others will say switch to a winter UQ and keep the TQ. My current set up is also 3-season (WB Mamba and Yeti), I may pull the trigger on a winter yeti versus a full length UQ like incubator 0*.
I live in Carlsbad, CA, so there's no 'go-outside-and-test' options for winter temps.
