Floral foam + water= Damp sponge. You are not regulating humudity, you are culturing mold. By changing to these "beads" you simply changing the method of delivering moisture. Most of us prefer a source that will absorb as well as release moisture as needed. I am not willing to risk my collection on such a foolhardy attempt to save a few dollars. My Heartfelt beads have kept my Rh steady at 62-65% for the last 3 years and I find them to be excellent investment.
