Manufacturing Process

How HortGrow container growing media are made?

HortGrow Solutions LLC of California works cooperatively with coconut fiber suppliers and manufacturers in India (HortBio Technologies PVT LTD) and in Sri Lanka (Wayamba Cocopeat). We partner with these manufacturers to produce superior growing media under HortGrow brand. At our Factories, we process raw coconut husks into its various coco fractions known as coco pith, fiber, and chips.  Using scientific research and our experience as active growers of soft fruits, we create our versatile and sustainable growing media with optimum water and nutrient retention and aeration to nurture superior container-grown plants.

01

Collection of Coconut Husks
  • We choose coconut growing areas that are free from major contaminants such as toxic chemicals, salts and industrial pollutants
  • We collect mature and dried coconut husks from fresh-water grown coconut trees

02

Processing of coconut husks
  • Husks are submerged in pools with constantly replenishing fresh water for several months. Mature husks may also be processed without this step
  • Dehusking separates pith and fiber. Husks may also be cut in to chips and shreds of various sizes

03

Washing and drying of cocopith and fiber
  • Cocopith/fiber/chips used in our growing media are washed 4 times to lower salts to optimum levels with fresh water on concrete pads.
  • Buffering with Calcium Nitrate is carried out for certain applications
  • Washed pith and fiber are then dried under full sun to achieve a moisture content below 16% for processing
  • Well dried coco fractions are packed in sacs and stored dry for several months to achieve optimal maturation

04

Pressing cocopith and fiber into final product
  • Each lot of well aged coco fractions are again tested to ensure optimum EC and pH and are sifted to remove any grit or extraneous matter
  • Sieved cocopith, fiber and chips (as required) are pressed into functional shapes, according to customer requirements
