Growstones Hydroponic Growth Mediums and Soil Aerators Deliver Superior Air and Water Retention for Superior Plants.

Growstones are a horticultural, scientific and environmental win-win-win. They are a breakthrough substrate environmentally engineered from discarded glass. Never strip-mined or shipped long distances like perlite or Hydroton they help create happier plants and a healthier planet.

Growstones are highly porous, chemical and toxin-free hydroponic growth mediums and soil aerators engineered to deliver superior air and water retention ratios for superior plants. They can be customized to fit a wide range of plants and climates as well as different growing systems.

While other substrates maximize either aeration or moisture, Growstones are designed to maintain the proper air and water balance in the roots without the danger of overwatering.

Growstones deliver higher oxygenation of roots than rockwool as well as better water retention than perlite making them a superior substrate without the environmental issues of other available products.

Their lightweight, dust-free composition make them easy to use and their results make them easy to love. Growstones make everything better. Your plants and our planet.
