In order to simplify the choice of coir Coco-peat products PreMiereCocos.com® has defined four quality of coir. By controlling all stages of production and having the ability to treat the coir Coco-peat, PreMiereCocos has the ability to guarantee treated products as well as non treated products. PreMiereCocos's experience enables PreMiereCocos to recommend the best and required quality of Coco-peat Mixture for each specific plants and crops grower.

Treated Coir Peat Coco-peat

"PreMiereCocos" has identified the need of some growers to receive the Cocopeat after it was treated with CaNO3. Therefore PreMiereCocos offers its customers, treated materials which were treated with CaNO3, and then washed with clean water. The treated products are very popular in vegetables nurseries and flowers nurseries.

It is possible to buy treated products that were disinfected with steam and treated pathogens, weeds and seeds We show here a sample of treated material that was tested in a trustworthy laboratory. The results in the table are for demonstration.

PremierCoco's method for Coir Coco-peat extraction

  1. The compressed Coir Coco-peat is reconstituted to its full volume by adding distilled water in the required amounts. The moisture should be such that when a gentle squeeze is given, few drops of water ooze out between the fingers. The reconstituted wet sample is then mixed well and left overnight.
  2. From the above material 60 ml of the sample is placed in a measuring cylinder. A gentle pressure of 10 kPa is applied over this while filling. Alternatively a measuring device with a provision to apply this pressure can also be used to achieve consistency.
  3. This sample is emptied into a conical flask to which 90 ml of distilled or de-ionized water is added. The flask is well shaken by placing it on a mechanical shaker rotating at10 rev/min for 15 minutes. Allow it to stand for 30 minutes and filter the extract through a low-mesh filter paper.
