Agrolite Perlite is a uniquevolcunic mineral which expands to about 13 times its original volume when it is heated to a temperature of approximately 1700^oF (927^oC) during the heating process, the mineral particules pop like popcorn and forms a granular, snow-white material so light in density that it weigh only 5 - 8 pounds per cubic foot (80 - 128 Kg/cubic meter).

Each partical of agrolite perlite is comprised of tiny closed air cells or bubbles.   The surface of each particle is covered with tiny cavities which provide an extremely large surface area.  These surface cavities trap moisture and make it available to  plant roots and to the stems of cuttings.  In addition, because of the physical shape of each Agrolite Perlite particle, air passage are formed in the growth mix providing optumum aeration.

Features

• Improves aeration and drainage
• Makes moisture and nutrients readly available to plants.
• Is inorganic and doesnot deteriorate.
• Has essentially neutral pH of 6.5 to 7.5
• Serves as an insulator to reduce extreme soil seterile and is free of weeds and disease.
• Is clean, odorless, lightweight, and safe to handle.

Applications

• Plant Propagation - Is a standard among professional nurserymen mainly for the "sticking" of cuttings. Agrolite Perlite may be used alone or with peatmoss in various proportions.
• All purpose grade - Agrolite Perlite is ideal for container growing of pots, planter boxes hanging plants, etc. An excellent potting soil is produced by mixing equal parts by volume of Agrolite Perlite and peatmoss or other humus.
• Soil amendment - Agrolite can be of great benefit to lawn, vegetable and flower gardens where the native soil is heavy and sticky.  In this case it will markedly improve aerationa nd dranage. On the other hand this grade of Agrolite Perlite can be very beneficial in loose, sandy soils where it will improve water and nutrient retention.
• Soil conditioner - Commercial growers often use the term "soil structure" and "soil texture" interchangeably in discussing solid characteristics, but this is neither acurate or correct. It provides excellent material to use as a soil conditioners because of its unique characteristics.
