What is Coir?
Coir is made from grinding the husk of a coconut. It is an organic and environmentally friendly product used for horticultural and hydroponic practices. This growing medium is the sustainable choice for soil-less cultivation and can be manufactured into grow bags for soft fruits, vegetables and flowers.
Unlike other crop yielding products such as peat moss or rockwool, coir is completely harmless to the environment.
Coir, also known as cocopeat has the ability to hold excessive amounts of water in, right levels of air porosity, and deliver consistent supply of moisture and nutrient to the crop. Fibrous in nature, coir holds many air pockets which helps the crops to root profusely. The rise in the surface area of the root system facilities the better absorption of nutrients from the soil. Coir also absorbs water rapidly and the high retention prevents the dehydration of plants in high temperature climates.
The substrate has a relatively good structure stability and is very easy to handle. Coir has a big CEC (cation exchange complex). This is a negatively charged complex, that is naturally saturated with sodium (and potassium). Calcium and magnesium however have a stronger attraction to the coir complex.
