» GS-1 Hydro Stones

Engineered Hydroponic Substrate For Consistent Results

GS-1 Hydro Stone is the perfect media for your hydroponic garden. Even though you’re growing hydroponically, your roots still need a stable and well-drained foundation for maximum stability and growth. GS-1 provides that perfect foundation with a highly porous, non-compacting non-clogging substrate, which facilitates aeration of the root environment. Roots will grow and be ready to take full advantage of the dissolved nutrients and oxygen.

GS-1 is the larger size stone in the range; perfect as stand-alone medium or can be added to coco or soil for powerful 60/40 or 50/50 mix.

Why Use GS-1 Hydro Stones

  • Delivers 40% more aeration than other mediums
  • Holds 3 to 4 times more water content than clay pebbles
  • Helps nutrients and oxygen flow more freely
  • Ultra light-weight and easy to handle
  • Simple to prep for pH stability

How To Use GS-1 Hydro Stones

As with all grow media; the more time taken to prepare a substrate pays off by giving you a pH-stable nutrient solution, which will be easier to correct and maintain later on.
