The Coconut Coir Difference

Coconut Coir as a growing medium

Why Coconut Coir?

Coir is quickly becoming the most popular growing medium used in aquaponics. Coir is the fibrous material found between the hard internal shell and the outer coat of the coconut.

  • 100% natural by-product of coconut processing
  • Naturally balanced pH
  • Naturally free of bacteria, plant disease, fungal spores, weeds, seeds or pathogens
  • Holds water well, up to ten times its volume
  • Biodegradable and Compostable

Net Pot Not Required

The grow pucks do not require a net pot when used with the PFC pre-formed Expanded Polystyrene Rafts. Eliminating the necessity of a plastic net pot, as used  with loose coir, the puck is disposable, compostable with a cotton outer shell as the pot.

Vermiculite Free

Loose coir and vermiculite are frequently mixed and used in net pots by many practicing and teaching aquaponics. The vermiculite is used to create over compaction. Vermiculite is a know carcinogen (causes cancer).

First we eliminated vermiculite with our proprietary blend of pure coconut fibers and particles. Next we eliminated the net pot with our compostable cotton shell, allowing us to get OMRI Certification. This eliminates the labor of cleaning the net pot, saving both time and money.

The grow puck consists of coir and cotton mesh, making it both compostable and disposable.
