Just remember,even with beads you need to open the coolerdor door/lid now and then.Stick a fan from a pc with a battery in there for flow of fermented gases....unless its just box storage.
If boxes are stored,only the non varnished cedar boxes need not be propped open,I think dressed cardboard ones too.I keep my lids slightly open a tad for airflow and a fan to circulate twice a day and open the lid for an hour before filling with water and once a week.
I also keep a big piece of foam with distilled water because the heartfelt beads are not the best at giveing humidity but excellent at takeing and maintaining.With cooladors and tuppadors with tight air tight seals,foam and or other humidity source isnt really needed with beads as the new sticks' moisture will take care of things.


I keep tupadors cracked a tad too and they stay at 65% with beads and also rid the tuppador of fermentaion gases.
