All mold cares about is humidity. If relative humidity is over like 55-60% then mold will grow. That's it. Stale air and lack of airflow help to keep humidity high because air is not being circulated evenly. You can get pockets of high humidity in certain areas. So that will add to the chances of mold.
Technically it’s a combination of absolute humidity and temperature. Bathrooms can be prone to mold even if they’re not any more humid than the rest of the house, because metal plumbing can conduct heat out of the room into the ground—causing the room to get cold enough for moisture to condense even if the water fixtures in the room aren’t in use.
Yeah, for sure. Relative humidity is influenced heavily by temperature so i kinda baked that into my answer haha.
