Coir Hydrating and Buffering

Coir Hydrating and Buffering

Coir is simply Coconut Husk in varying grades of coarseness.  As Coconut is grown close to the sea there is usually a certain content of Sodium Chloride present.  Sodium is quite poisonous to plants.  Some plants are more susceptible to Sodium damage than others.  Lettuce for example is very susceptible whilst tomatoes are less susceptible.

Due to the above it is strongly recommended that the Coir is thoroughly rinsed and preferably ‘buffered’.  Buffering is achieved by the addition of 1kg of Calcium Nitrate being added per 1 cubic metre of Coir.

When you receive the Coir it will be in a solid block.  This block is hydrated by the addition of water.  It simply swells up many times it size.  we recommend that after hydrating it you rinse it a lot, say change the water in it by 4 times as a minimum.  After rinsing add the Calcium Nitrate.  You may add the Calcium Nitrate by either adding its solid state or by dissolving it.  If you add it in its solid state we recommend that you wash it into the Coir.  Leave the Calcium Nitrate in the Coir for 24 hours and rinse it out thoroughly.  The Coir is then ready for use.
