Broken Brick
Broken brick is large inorganic chunks that are ideal to provide support for orchids grown in large vanda baskets. Broken brick is popular in wet climates for its modest moisture retention properties. Broken brick can be used to provide weight in the bottom of a pot, and to aid drainage in much the same way that chards of broken clay pots would be. For terrestrial orchids, layer peat, coir or soiless mix on top of broken brick for drainage.
