The appearance of nutrient syderolite is rotundity and oval.The diameter is from 3mm to 10mm. Big syderolite and small one are mixed.So there is no difference about the grade.
Nutrient syderlolite is made of clay which is from Guizhou Province in China.We append 12 kinds of elements including nitrogen,phosphorus,kalium,calcium,magnesium,sulfur,ferrum,boracium,manganese,zinc,cuprum and molybdenum which are necessary to plants.
Clay is treated in high temperature of around 850 centigrade .The appearance of clay become to syderolite.They are acidic,and the PH value is 6.79.
The syderolites contains lot of pore which has strongly adsorbability .Water and mineral elements are contained in the pore.Beacause nitrogen,phosphorus and kalium are needed plenty,they are consumed very promptly.You can recharged them with nutrients.Treated by high temperature ,the syderolite has no plant diseases.So they don't house microbial consoutiums of benificial bacteria and beneficial funfal colonies.The syderolite contains no organic substance,so it can't give birth to smell unpleasant.
By right of our experimentation and the reflection from consumers,the syderolite is very suitable to grow plants.It is particular to grow orchid .
Because it can't give birth to diseases,the syderolite is widely used to grow plants and nuisance-free vagetables.It can be used in hydroponics or bioponics too.In the attachment,there is one photograph in which the syderolite is put into fish jar to plant float grass.
We are pleasure to provide sample.But we hope you can afford the postage and we will don't charge the cost of the sample.
We can also provide special flowerpots which match with nutrient suderolite.Plants will not grow well if you water them more or less.But our flowerpot can control the amount of water .
