pH: 5.4 – 6.8 Perfect for use as a growing medium
Air Filled Porosity (AFP): 10 – 11% perfect for use as a growing medium.
The Air Filled Porosity (AFP) of a growing medium defines the air spaces in the pot needed for good water dispersal and drainage, and to allow good healthy root growth.
Root growth: With coir you will find this will be much faster, making it excellent for cuttings. In some cases freshly repotted plants may appear not to be growing for a week or so but if you check, they are growing roots rather than tops.
Water Absorption Time: Immediate wetting/re-wetting time is immediate
Cation Exchange capacity: In excess of 120 meq/1000 combined with a good conductivity figure allowing holding and dispersal of nutrients.
Carbon/Nitrogen: Ratio of between 90:1 and 110:1. This combined with coir’s lignin content makes it a good long term growing medium.
Nutrition: Coir contains a useful amount of available potassium, and small quantities of:
