RIOCOCO PCM Open Top Grow Bags are produced with a special blend of coconut fiber raw materials, which provides the ideal substrate characteristics to the plants.  The selected raw materials are five times washed, blended without fine dust particles to make PCM bags for the required sizes.  This Coir Open Top Grow Bag is specially designed to reach the optimum water holding capacity (WHC) and air-filled porosity (AFP).  

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. 
  • 100% natural, organic coir-based components
  • Neutral pH and Low EC (Salt content)
  • Inert and Sterile
  • Exceptional ability to retain and release nutrients
  • High porosity
  • High composition of lignins
  • Uniform in composition
  • Biodegradable and compostable
  • Will Coir reduce water usage?  Yes.  Compared to open field operations, Coir can save up towards 90% water usage for large greenhouse operations.
  • Are there benefits to using Coir over Rockwool?  Yes:
    • 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.
  • Are the bags biodegradable?  Yes.  The bags are Ecopure so they can run through the chipper or sent to the compost pile where the compost or landfill microbes will activate the enzyme in the bag to completely break down in 6-8 months.
  • Do the grow bags need to be hydrated?  All grow bags are dehydrated less than 18%.  The Open Top Bags are pre-drilled with dripper holes.
