Net cups provide a secure place for your plants inside a vivarium. Net cups can either be incorporated into a background, or placed directly into the substrate of your vivarium. Net cups allow free drainage of excess water, and their open design eliminates the threat of root binding. Great for vivariums, terrariums, and propagating plants.
