Vermiculite
Vermiculite features
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 temperature 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 intert
and neutral PH:8-11.

1, In our nursery, we find that the soil there is clay type. The roots cannot grow well. How your vermiculite works to decrease or avoid the roots to rot?
--When water too much, our vermiculite can store the excess water to avoid the root rot;while water too little, it can release water to guarantee the plant water content.
2,We can not see the product progress so cannot know whether the goods quality good or not.
