Rocky Points new industry- leading fibre substrate
RP HydroGro Wood Fibre is a revolutionary growing medium that has been a staple in European and American horticulture for over 30 years. After three years of research and development, with both internal and external grow trials here at Rocky Point we are excited to introduce to the market – RP HydroGro – a Wood Fibre substrate.

What is RP HydroGro?
RP HydroGro is created using a thermal refinement process. Pine chips are defibrillated under high pressure, transformed and sterilised exceeding 100-degree heat which produces fine, long strands of fibre with an expansive surface area. These unique fibres maximise moisture availability, making RP HydroGro’s properties similar to coir pith and peat moss. Unlike these imported products, however, RP HydroGro is a local Australian-made substrate. Our timber stock is sourced from PEFC-certified sustainably managed Australian plantations making this a truly sustainable resource.
RP HydroGro has been engineered to optimise water retention and plant growth. It is an advanced fibre substrate offering low bulk density which cultivates aeration and root development.

Pine trees
Pine Trees
It starts with Australian sustainably sourced pine tree, we use Pinus elliottii, Southern pine (lob lolly pine), and Pine caribae- Caribbean pine.
Wood chips

This is then broken into raw pine bark chips that is loaded into a specialised machine to defibrillate and grind into tiny fibres.

Q & A
How does RP HydroGro compare to peat or coir?
RP HydroGro has similar abilities to peat and coir, but RP HydroGro is locally supplied and sustainable. RP HydroGro comparatively has greater re-wettability. RP HydroGro has been tested to absorb water in 13 seconds, whereas peat moss has little re-wettability and coir pith can take up to six times as much to absorb.
What species of pine are used?
We use Pinus elliottii, Southern pine (lob lolly pine), and Pine caribae– Caribbean pine.
Why is wood fibre white in appearance in potting mix?
Rocky Point HydroGro is made from a soft wood pine chip which is white in appearance. It goes through a process of extreme pressure and temperature which sterilises and defibrillates the chip leaving the fibres ready for use and the colour intact.
