Hydrocell units are old hat these days. In the past years many of those were sold and put inside uprights and grands. Indeed, one had to fill them either in a special plastic bag, or just put them in a tub. I think inside an upright, they worked pretty well, because if you checked the (inside) humidity with a humidity gage, it showed much more humid after refilling the hydrocell. The negative side of those things was, that after a year or two, the insides (the filling) got hardened and did not really absorb water anymore (I do know about it, because I sold quite a lot of these). I am now greatful for dampp chasers.
