Stonewool/Rockwool is recognised the world over as the ideal hydroponics growing substrate. Rockwool is known for it’s quality, consistency and performance against other substrates.

Rockwool is manufactured by melting basaltic rock and spinning the molten mix into fibers which are then air cooled and compressed into the blocks we use today. By adjusting the amount of pressure, the density of the medium is adjusted. The large slabs can be cut into smaller slabs and propagation blocks for easy handling in the hydroponic and horticulture industry.

  • Environmentally friendly.
  • Light weight.
  • Naturally a medium with plenty of aeration.
  • Easy to handle, cut and install.
  • Comes in a range of sizes from propagation cubes to large slabs.
