I was wondering how accurate the beads really are. Would i need a hygrometer still if i kept the beads moist? I have heard they keep great accurancy and need very little maintanence and i wondering if i would save on buying a hygrometer if its guarenteed to hold say a 65% humidity level. I mean as long as i keep them moist it shouldn't be a problem right?

Im brand new at this so sorry for any ignorance. I really appreciate any knowledge past onto me.
