This time I did not use the named DeLonghi dehumidifier but an ALDI Nord Quigg 20/d dehumidifier. And I did not use it a lot. Just at times, when had more than over 80% humidity.
Since its my first time, I can say the product is good. But I had some problems with wth Hydro Grow bottle. Dont know why but some salt crystals were fallen off in the bottle. So u could hear them if ı rolled the bottle. So b4 u buy rollt the bottles and listen. Because of wrong storage the chemicals could get old fast.
