Depends on a lot of things, mainly the enclosure and the size of bowl (and distance to the hygrometer). My plastic enclosures manage to keep theirs at about 40-44 this time of year (without "assistance"), which is great compared to what I used to get in all my previous enclosures. Even with a large water bowl, there were times when it would drop to less than 20% during the winter. I think the record low was 18%, which is low enough to safely store grain.
