How Should the Soil and Clay Pellets Be Mixed?

Clay pellets are a soilless growing medium made from small, hard-fired clay balls. The pellets are usually between .03 and .08 inches around. The firing process causes the clay to expand creating a porous medium. Clay pellets are most commonly used in hydroponics and for orchids and other plants that require a soilless growing medium. Use clay pellets to increase drainage in potting soil mixes for houseplants and other container grown plants and trees.
