This growing medium is made by heating small clay
pellets to 2000 F. At these temperatures the clay expands, developing a
hard shell and tiny air spaces in the core.
ceramic shell promotes strong capillary activity and minimzes salt
buildup. The hollow inner core absorbs moisture that will be used by
the plant's root system.
pebbles are a sterlie ceramic that will not compact, decompose, or
harbor mold and disease. Their irregular shape promotes good air
circulation around the root zone, creating a stronger root system and a
