RIOCOCO PCM mix coir block is made from fresh coir fiber natural and crush chip materials blended together and compressed to a 4.5kg/10lb format.  It is five times washed and heat-treated before compressed.  It has over 28% air fill porosity and moderate water holding capacity.  Natural PCM coir mix can be used straight without adding any perlite or any other type of amendment to increase aeration.

All RIOCOCO soilless coir growing mediums are processed from coconut trees in the island nation of Sri Lanka and utilize the natural properties including the fiber, pith and fractions.

    • Coir is biodegradable.  Rockwool is made of basalt and chalk so it will not breakdown.
    • Coir costs less than Rockwool.
    • Coir is pH neutral and sterile.  Rockwool often has higher pH levels which can lead to plant nutrient deficiencies, slow growth rate and difficulty in plant flowering
    • Coir does not need buffering.  Rockwell must be buffered and prepped before being used.
    • Coir is Hydrophilic.  Rockwell will tend to dry out quickly.
  • Can Coir be blended with other products?  Yes.  Coir is often used to replace peat moss to amend and aerate soil.  Coir can be used as a planting medium on its own, or blended with other products to make custom mixes.
