 2.Vermiculite advantage

1). Physical appearance

Vermiculite refers to a small group of minerals resembling the lamella structure of the micas.It is dark gray brown to golden brown in color and flake-shaped when dry.When heated to intense temperatures vermiculite expands in volume and its lamellae separate,and thus exfoliate

2). Moisture retention

The space created by exfoliation trap moisture.Ideal for horticultural applications, vermiculite has the capacity to retain several times its weight in water.

3). Air circulation

Vermiculite flakes are irregular in shape allowing better air circulation when exfoliated, .Widely used in horticulture to aerate soil mixes or for hydroponic cultures.

4). Low density

Exfoliation cause a great increase in volume without an increase in mass.Being extremely lightweight,vermiculite is an ideal material to lighten aggregates such as concrete,plaster,and asphalt,and to fill walls and partitions Inert and neutral PH:8-11

3.Vermiculite used for horticultural

Exfoliated vermiculite has been long established in the horticultural market.  Mixed with vermiculite , peat or other growing substrates it is used to produce a range of growing media to suit every application. 

Vermiculite increases aeration and moisture retention, and through its high cation exchange capacity it minimises fertilizer leaching.

Manufactured at high temperatures, vermiculite is sterile.  It is an excellent carrier and extender for fertilizer and pesticides and works well as packing material for bulbs and tubers.

4.Perlite expanded for horticultural

1>Perlite is used throughtout the world as a component of soilless growing mixes where it provides aeration and optimum moisture retention for superior plant growh.For rooting cuttings,100% perlite is used .studies have shown that outstanding yields are achieced with perlite hydroponic systems

2>Perlite are its neutral PH and the fact that it is sterile and weed-free .in addition ,its light weight makes it ideal for use in contaner growing

3>Perlite are as a carrier for fertilizer ,herbicides and pesticides and for for pelletzing seed.Horticultural perlite is as useful to the home gardener as it is to the commercial frower .it is used with equal success in greenhouse growing ,landscaping applications and in the home in house plants
