History of Growstone

In response to the destructive pumice strip-mining they saw taking place in Northern New Mexico’s Jemez Mountains, Growstone’s founders saw an opportunity for replacing these strip-mined products across many industries. Their work resulted in a number of alternative agricultural products to the commonly used and strip-mined hydroton, perlite and pumice – all created with foamed glass from recycled bottle glass.

Working with Dr. Gene Giacomelli, Director of the Controlled Environment Agriculture Center at the University of Arizona, and then graduate student, Paula Costa (now Dr. Paula Costa, our Director of Research and Development at Growstone), they explored the potential of a “rigid foam glass” as a new substrate for hydroponic production.

What they discovered was nothing less than revolutionary. A sustainable growing medium that wicked water fast, retained a relatively large amount of water after readily draining the excess, was easy to rewet after being dry, and had a very high air filled porosity even after irrigation. This new and highly steerable aggregate base substrate became known as Growstone.

Between 2006-2009, Growstones were used in multiple greenhouse trials. Every trial confirmed the high performance capacity of Growstone for hydroponic crop production.

Growstone then approached the City of Albuquerque to take the discarded bottles in New Mexico’s landfills for Growstone production. Today, Growstone takes over 250 tons of discarded glass bottles out of New Mexican landfills each month and turns them into high-performance horticulture products for the hydroponic and garden markets.

We’re growing a revolution!
