Horticultural Perlite
Perlite is a unique volcanic mineral which expands from four to twenty times its original volume when it is quickly heated to a temperature of approximately 1600-1700 degrees F. This expansion is due to the presence of two to six percent combined water in the crude perlite rock which causes the perlite to pop in a manner similar to that of popcorn.
When expanded, each granular, snow-white particle of perlite is sterile with a neutral pH and contains many tiny, closed cells or bubbles. The surface of each particle is covered with tiny cavities which provide an extremely large surface area. These surfaces hold moisture and nutrients and make them available to plant roots. |

|
|
|
In addition, because of the physical shape of each particle, air passages are formed which provide optimum aeration and drainage. Because perlite is sterile, it is free of disease, seeds, and insects.
Perlite has been used for many years throughout the world for soil conditioning and as a component of growing mixes with materials such as peat moss or bark. Extensive studies have shown that the unique capillary action of perlite makes it a superior growing media for hydroponic cultures.
Among the many uses of perlite today are propagation and seed cultivation, plug production and transplants, interiorscape and planter growing, composting, hydroponic cultures, turf and lawns, and around shrubs, trees, and landscaping.
Schundler Horticultural Perlite is available in 4 Dry Quart (1 Dry Gallon), 16 Dry Quart (4 Dry Gallons), and 48 Dry Quart (12 Dry Gallons, 1.5 Bushel) sizes. 1.5 bushels is equal to 1.86 cubic feet. For more information about the origins of perlite and its current uses, please visit The Perlite Institute at http://www.perlite.org.
Special Note: Schundler Company has experienced a devastating fire and will no longer be producing consumer size bags of perlite and vermiculite. As our present stocks sell out, we will be switching over to Hoffman Brand perlite and vermiculite. Hoffman Brand will be available in 8 dry quart, 18 dry quart, and 2 cubic foot bags. |

Coarse Horticultural Vermiculite
Vermiculite is a member of the phyllosilicate group of minerals, resembling mica in appearance. It is found in various parts of the world, but currently the major mines are located in South Africa, China, Brazil, Zimbabwe, and the United States.
The largest mine today is located in the Palabora region of North-Eastern Transvaal in South Africa. It's vermiculite is basically a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated---a property known as exfoliation.

Horticultural Vermiculite has the excellent property of improving soil aeration while retaining the moisture and nutrients necessary to feed roots, cuttings, and seeds for faster growth. Like perlite, horticultural vermiculite is permanent, clean, odorless, nontoxic and sterile. It will not deteriorate, turn moldy or rot. The pH of vermiculite is essentially neutral (7.0-9.5) but owing to the presence of associated carbonate compounds, the reaction is normally alkaline. It also will vary (become more alkaline) with changes in processing techniques and time, and with the presence of moisture. The pH, color and chemical composition of vermiculite also will vary from mine to mine.
Vermiculite possesses cation exchange properties, thus it can hold and make available to the growing plant ammonium, potassium, calcium and magnesium. When mixed with peat, composted bark, organic compost, or natural soils, vermiculite like perlite helps promote faster root growth, and gives quick anchorage to young roots. These mixes help retain air, plant food, and moisture, and releases them as needed by the plant. Because vermiculite is very light and easy to handle, it easily mixes with soil, peat, composted pine bark and other composted organic materials, fertilizers, pesticides and herbicides. And when used as a carrier or bulking agent, it ensures more even distribution.
Schundler Horticultural Vermiculite is a coarse grade vermiculite with a varying average diameter of 1/4 to 3/8th inch. Available in 16 Dry Quart (4 Dry Gallons) bags. For more information about the origins of vermiculite and its current uses, please visit http://www.vermiculite.com.
Special Note: Schundler Company has experienced a devastating fire and will no longer be producing consumer size bags of perlite and vermiculite. As our present stocks sell out, we will be switching over to Hoffman Brand perlite and vermiculite. Hoffman Brand will be available in 8 dry quart, 18 dry quart, and 2 cubic foot bags. |

Mother Earth
Large & Coarse #4
Horticultural Perlite
Mother Earth Perlite begins as naturally occurring siliceous rock. After it is heated to 1,600 degrees Fahrenheit, the rock expands up to 20 times its original volume. This kilning process is similar to popping popcorn and produces a growing medium that is sterile and has a neutral pH of 7.0.
The exceptional physical properties of this giant perlite make it tops in the perlite world for adding porosity to soil, soilless mixes, as well as hydroponic applications.

|
|
|
|
|
|
Garden Tip: In containers, spread Mother Earth Large & Coarse Perlite in a one-inch layer along the bottom of the pot, then mix one part Mother Earth Large & Coarse with four parts potting soil. Water thoroughly and allow soil mixture to settle before planting.
In hydroponic systems, fill pot with Mother Earth Large & Coarse Perlite, and position plant properly so its root system is supported in the medium.
Mother Earth Large & Coarse Perlite #4 measures between 1/2 and 1 inch in diameter and is available in a 4 cubic foot bag.

PVP Perl-Lome
Horticultural Perlite
Perl-Lome Horticultural Perlite is a semi-coarse soil additive that improves soil structure, eliminates soil crusting and compaction and improves drainage and aeration. Among the unique properties of Horticultural Perlite is its ability to work for many years in the soil. It does this because it is inorganic and does not deteriorate. In addition, perlite is chemically inert and has an essentially neutral pH.
Because it is sterile, perlite is free of disease, weed seeds and insects. Its light weight makes perlite easy to handle and is clean and odorless too. |
|
|
|
|
|
|
As a soil additive mix equal parts perlite and soil. Moisten and mix thoroughly. Firm the mix well around the roots but do not pack too tightly. Water thoroughly.
For starting seeds or cuttings, mix equal parts of perlite and soil. Moisten thoroughly and add your seeds or cuttings. Pack gently. Approximately four weeks later transplant to growing container. Eight (8) dry quart (8.8L) bag. |
