Hi, Yes i put my Girls after the Flushs into my natural cellar, it was cool and dark.(around 18 degree and 50 percent rh) I looked daily for them. First day everything was fine. Second day started to rot ( mold). I harvestd them immediatey. If I look back i would say, A fresh flushed Pot dont belong to a dark and cool cellar. I think 24 hours will be ok , but longer you need some airflow . I would tra to give the plant similar conditions Like in the growbox for temperature and HUmidity and airflow, then you dont get problems, if it provides the Quality of the Harvest, i honestly can tell you.
