Know more about Coir Disc

Coir discs, also known as coco discs, are small, compressed discs made from coconut coir (fibers from coconut husks) that expand when moistened, providing an excellent growing medium for plants. They are commonly used in nurseries and for seed starting due to their water retention, aeration, and drainage properties.

Specifications of Coir Discs:

• Material: 100% natural coconut coir.
• Composition: Primarily composed of cellulose, lignin, and hemicellulose.
• Color: Natural brown or yellow.
• Moisture Content: Typically less than 15%.
• EC (Electrical Conductivity): Usually less than 0.6 millimhos/cm, indicating low salt levels.
• pH: Typically ranges from 5.8 to 6.8.
• Impurity: Less than 3%.
• Weight: Varies, commonly between 3 and 80 grams.
• Diameter: Ranges from 30mm to 100mm.
• Thickness: Typically 1cm.
• Expansion: When hydrated, coir discs expand significantly, providing a larger volume of growing medium.
• Types: Available as plain discs or covered with a non-woven cloth.
• Packaging: Often sold in boxes, with the number of discs per box varying based on size.
• Applications: Used for seed starting, as a growing medium in pots, and as a component in potting mixes.

Additional Specifications:

• Covering: Some coir discs are covered with a non-woven cloth to improve stability and ease of handling.
• Expansion Volume: Compressed coir discs expand significantly when wetted, with some expanding 4-6 times their original volume, according to a manufacturer.
• Fines Content: May be specified to have a low percentage of fine particles to optimize aeration and drainage.
• Impurity Level: Should be relatively free from impurities like sand and other foreign materials.
• Packaging: Typically packed in boxes, with the number of discs per box varying based on disc size.
