Pargro is lightweight stone wool made from basalt rock. It’s a highly uniform substrate that’s pathogen, disease, and seed-free, offering consistent plant growth.

Pargro media has rapid water distribution and excellent re-saturation capabilities, making it easy to use.

  • Vertical fiber orientation; inert hydrophilic fiber technology
  • Uniform slabs ensure plants will have uniform crop development through to harvest
  • Easy irrigation and good EC refreshment thanks to the fiber structure as well as the loose wrap
