WoldoClean plant adhesive is a simple and non-toxic method to attach aquarium mosses and ride-on plants to wood, roots, decorations and clay hiding places. The adhesive is best used on dry surfaces, because when in contact with water it becomes firm. Smaller moss pieces of about 1-2 cm length are simply applied to the surface with a few drops of the plant glue; ride-on plants are attached with the rootstock. In about half a minute, the glue hardens, turns whitish and is finally completely covered by the moss.
