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.  For more information see how to use net cups see our article on how to plant epiphytes or how to use net cups when building a background for your terrarium.
