Coconut coir are fine fibres from the husks of Coconuts. It is a versatile substrate and can be used in pure form or in a mix for a variety of applications. It is clean and free of bacteria which makes it the ideal substrate for growing microgreens, edible flowers and vegetables. Commonly used in seedling mixes, aquaponics, hydroponics and commercial farming.

When selecting grow medium for microgreens or any growing practices, it is important to know the characteristics of the medium and its uses. Coco Coir, Vermiculite and Perlite are extremely clean and free of harmful chemicals.

Washed Coco Coir VS buffered Coir

In short, washed Coco Coir has been through a simple washing process that removes water soluble components like sodium. Buffered Coco Coir gos through a further process where the sodium and potassium are replaced by calcium.

If the sodium and potassium is not replaced, the fibres will draw out available calcium and magnesium from the seeds or available nutrients. In other words, there are less nutrients available for plants

Which one should you use?

Microreens grow better and stronger with buffered Coco Coir. Peas for instance struggle heavily in unbuffered coco coir. We highly reccomend using buffered coir for best results.

Our recommended mix is 1 kg Coco Coir : 10 L water : 2 L Perlite : 2 L Vermiculite

The process:

In a clean container add 1 kg Coco Coir, add 10 litres water. The Coir will expand and soak up all the water. Make sure there is no dry bits. Then add 2 litres of Perlite and 2 litres of vermiculite and mix. This should be enough for 10-12 standard 53 x 27 x 3 cm grow trays.

Origin:

Coco Coir is originally from India. It is a product of the inner fibres of the coconut husk. Fibres are washed with water, dried and compressed into blocks.

Please note our Coco Coir blocks vary in weight. This is due to the manufacturing process being quite variable. The large 5kg blocks weigh between 4 and 5kg.
