The absolutely best way to store any sleeping bag is to lay it out flat in a cool, dry place with good air circulation. Quilts and bags that open flat can be put into a duvet and used like a comforter. But you are in Florida. I presume your home is air conditioned because you are mobile enough to post here. But if your closets get warm and humid, watch out. I keep my quilts (I don't use sleeping bags) that are not being used in a comforter laid flat on a bed in a spare bedroom. I turn them when I think about it.
