My Adventure With DIY Concrete Foundations

I see what you're getting at, but honestly, intermittent ventilation can work pretty well if you get the timing right. The key is consistency—shorter bursts might feel effective, but humidity doesn't clear out instantly. I've found that slightly longer cycles at moderate airflow tend to balance things out better. Had a similar issue on a basement reno last year...took some tweaking, but eventually nailed it by extending the ventilation periods just enough to keep humidity from creeping back up.
