While many adhesives can be used to attach Tillandsias, Tilly Tacker is applied at room temperature, unlike hot glue, and it is completely waterproof, unlike most adhesives. Finally, due to adhesive brittleness, degradation, and dissolution, the plants do not come off over time. We have used it for our wholesale mounted Tillandsia production for over 25 years and we cannot imagine attaching the Tillandsias with anything else. We wholeheartedly recommend it.
