Whether you grow hydroponically or in soil, Growstones not only treat the planet beautifully, what they do for your plants are nothing short of spectacular. They are made in the USA from start to finish.
Growstones are engineered for excellence in an eco-friendly exclusive process that requires no water. Even our kiln runs environmentally on landfill gasses. Unlike perlite and Hydroton, no destructive strip-mining or overseas shipping in energy guzzling tankers are ever involved in Growstone products or production. They are an environmental and horticultural win-win from start to beautiful finish.
