Perlite is a unique volcanic mineral which expands to about 13 times its original volume when it is heated to a temperature of approximately 1600 F (871C). During the heating process, the mineral particles pop like popcorn and form a gr
anular, snow-white material that is so light in weight it weighs only about 5 to 8 pounds per cubic foot (80-128 kg/cubic meter).
Each particle of 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. In addition, because of the physical shape of each particle or perlite, air passages are formed in the growing media thereby providing excellent aeration. Fertilizer appropriate to the plants being grown should be added. Horticultural perlite is available in several different grades. The coarse sand size has been used for many general gardening and horticultural applications, but the finer grades work best when used outdoors.
Advantages of Horticultural Perlite
Improves aeration and drainage
Makes moisture and nutrients readily available to plants
Is inorganic and does not deteriorate.
Has an essentially neutral pH of 6.5 to 7.5.
Serves as an insulator to reduce extreme soil temperature fluctuations.
Is sterile and free of weeds and disease.
Is clean, odorless, lightweight, and safe to handle.
Just as horticultural perlite has served the professional grower for many years, it can help the home gardener solve a multitude of common problems. In addition to promoting drainage and aeration in heavy clay soils, horticultural perlite provides optimum moisture retention for successful plant growth.
When horticultural perlite is added to heavy clay soils, water ponding and surface crusting may be eliminated. In addition, plant roots may more easily penetrate the perlite/soil growing media and develop more fully. Horticultural perlite can be particularly advantageous in modifying the structure of general garden soil, patio plantings, and roofscapes.
VERMICULITE, hydroponics,horticultural,seed starter,soil complement
grade: 3-6 mm
Vermiculite is always used in the horticultural sector in its exfoliated form and it has the benefits of improving soil aeration while retaining moisture and nutrients to feed roots, cuttings and seeds for faster, maximum growth.
Vermiculite:
Is permanent, clean, odorless, non-toxic and sterile and will not deteriorate, turn moldy or rot
Possesses cation exchange properties, thus it can make available ammonium, potassium, calcium and magnesium to the growing plant
When combined with other media such as peat or composted pine bark compost, promotes faster root growth and gives quick anchorage to young roots
Mixtures help retain air, plant food and moisture, releasing them to the plant as required
Is the preferred material by professional nurserymen for the rooting of cuttings
Is used as a carrier and bulking agent in fertilizers, pesticides and herbicides
Is part of the standard mix used in the very popular Square Foot Gardening system
