Isolite Origin  ISOLITE is diatomaceous earth that has been eated to 1800 degrees and then extruded into a range of sizes. (2mm to 1/8" diameter sized particles are commonly used in hydroponic culture. The microporous structure holds water   Characteristics  ISOLITE is chemically and physically inert. It does not absorb trace nutrients from hydroponic solutions, and it does not add potentially toxic trace elements to nutrient solutions. Roots will not attach to isolite, so it is a good media for university research and perhaps for raising high quality root vegetables.   Durability  ISOLITE does not breakdown over time, so it can be reused by heating it up to 82 degrees C (180 degrees F.). Since ISOLITE was originally fired to 1,800 degrees F., heating it up to that temperature to rid ISOLITE of any pathogens or chemicals will not harm the granules' integrity.
