To those in old retrofitted brick buildings in the north. How bad are your humidity swings?

We are in an old retrofitted brick building where the people designing the rooms opted for drywall and didn’t construct a bubble room as a buffer. As a result, in some rooms you can literally see where the studs are because there is condensation dripping down the wall in the winter. Also as a result, it’s extremely difficult to control humidity because of the thermal bridging between the cold air outside and the warm air inside the grow room. I have my dehumidifiers staggered to help but it’s a constant struggle. In the winter very early on in flower I’m able to achieve a dryer room but as I get more foliage and the plants are transpiring more later in flower I hit a wall with being able to keep humidity down without making changes to room temperature. Just seeing what’s others do that are in a similar position, or if you just roll with the punches.
